, hello. If false alarms occur from the shock sensor, then you just need to: 1. Check how securely the link sensor is fixed in the bowels of the car (sometimes it has to be re-attached or moved to a better place - for example, when mounted on plastic, the plastic crunches when the temperature changes and clicks and this triggers the sensor). It is better to mount the sensor on metal structures in the depths of the dashboard. 2. Adjust the sensor settings according to the trigger zones (if the sensor is already fixed to the metal and securely - does not dangle, then it is enough to slightly reduce the sensitivity of the sensor). 3. StarLine alarms are so reliable that their manufacturer gives them a three-year warranty and a service life of five years. But in reality there are alarms (installed by me) of this brand that have been working without problems for 8-9 years. And this is not the limit. In most cases, failures and false alarms are a consequence of unsatisfactory installation.

If you are not sure that you can handle checking and adjusting the sensor yourself, contact your nearest installation center link @x444ce

Starline A91 is one of the most popular car alarms in Russia. The great demand for it is supported by the combination of a large number of technical advantages with a reasonable price. One of these advantages is the Starline A91 two-level shock sensor, which is triggered if the car body encounters an external impact on it.

The sensor is protected from false alarms by special protection, which protects it, among other things, from the effects of electromagnetic interference. Correctly adjusting the sensitivity of StarLine A91, which is done immediately after installing the alarm on the car, helps reduce the number of erroneous reactions.

The Starline anti-theft system is distinguished by the presence of wide functionality:

special protection of the control panel;
reduced sensitivity to radio wave interference;
automatic engine start in different modes at a distance;
effective sensitivity of the “friend or foe” system;
capacious battery that does not require frequent replacement.

In addition to the above, the system operates reliably in a wide temperature range from -45 to +85 degrees, which is extremely important for the domestic climate.

Control is carried out using the 2 key fobs included in the kit, each of which is capable of influencing the device from a distance of 600 meters.

The efficient and correct operation of the entire StarLine system largely depends on the correct connection of two key fobs to the alarm system. To do this you will need to follow a number of steps:

Find the Valet service mode switch in the car, which allows you to enter the settings - it looks like a regular button and is often located under the glove compartment, steering wheel, or in the fuse box.
To activate the system, press the service mode switch seven times with the engine off.
Immediately after this, turn off the ignition and wait for seven beeps from the siren, indicating that the actions were performed correctly.
Turn on the key fob by simultaneously pressing keys number two and three - another signal will indicate its connection.

The system may not work correctly for various reasons, but the main ones are:

incorrect setting of the shock sensor itself;
unsuitable location for installing the device;
sensors and signal unit incorrectly attached to the body of the car.

Causes and solutions

According to experienced motorists, there are 4 reasons why the alarms of Tomahawk, Pandora, Sherkhan, Starline, Sheriff, Panther and others involuntarily go off:

The shock sensor may not work;
moisture enters the system;
the machine is loaded above normal;
The error is caused by the limit switches of the alarm system.

All anti-theft systems are equipped with a shock sensor. Its operating principle is quite simple: the device detects vibrations and sends a special impulse to the siren, which is activated and may not turn off.

The Starline sensor or another brand of signaling needs to be properly configured so that its activation is not erroneous. First you need to determine the location of the device. So, on Chinese analogues and on models of an older design, the sensor is separately brought to the central unit, where it is connected through wiring. There is a plastic screw on the outside of the case that allows for adjustment.

The photo shows the place for adjustment

Adjustment is carried out manually using a shaped screwdriver. You must be able to set the sensitivity parameter correctly so that Sheriff, Tomahawk 9030, Starline A91 or other alarms from the wind, passing cars, etc. do not go off on their own.

You cannot set a high threshold for the sensitivity of the shock sensor, since the alarm will constantly go off at the slightest reaction, for no reason. It is advisable to stick to average values.

On top models of anti-theft systems, this sensor can be built into the unit itself. To make adjustments in this case, you must read the operating instructions that come with any high-end device. The manual says how to use the key fob to adjust the sensitivity of the device.

If you couldn’t find a manual, you can adjust the device like this:

Disable the permanent alarm mode.
Enter the control unit into programming mode.
Press the key fob buttons while simultaneously holding C and H (the name and location of the keys are individual for different brands and models).

Models of modern sensors are displayed separately and mounted in the cabin under the dashboard. Instead of a tuning screw, keys are used to adjust sensitivity. Several levels indicate the degree of reaction of the device, but it is advisable to set it to the middle position so that the Tomahawk or other alarm does not start to go off on its own.

Why the alarm goes off and what to do

The following reasons contribute to the involuntary activation of the alarm mode in security systems of common manufacturers:

malfunctions of the shock and tilt sensors;
penetration of moisture into external parts of the system;
machine overload;
closing the limit switches of the security system (the alarm goes off on its own when the contacts oxidize).

Incorrect sensor sensitivity adjustment

The set of any anti-theft system includes sensors that respond to impacts and changes in body position. The principle of operation of the part is to detect vibration and send a signal to the siren, which is activated and does not turn off. The sensors of any alarm must be configured correctly. The work order includes the following steps:

Determination of sensor localization. In older models of security systems, sensors are located near the head unit, to which they are connected via cables. The housings are equipped with bolts with which the sensitivity is adjusted. In modern models of anti-theft systems, sensors are built into the head unit.
Adjustment. Using a screwdriver with a shaped attachment, tighten the bolts on the housings. You need to be able to change the parameters correctly, otherwise the alarm on your car will go off frequently for no reason. You cannot set a high degree of sensitivity, because the sensors will react to the slightest vibration.

The sensor parameters of modern alarm systems are configured using a key fob. The sensors are adjusted as follows:

The system is disarmed. The control unit is prepared for programming.
Press key fob buttons 1 and 2. The location of the service keys and their names depend on the brand and model of the anti-theft system.
The sensitivity of the sensor is adjusted using buttons. Each level indicates the degree of sensor response. It is necessary to select average values at which false alarms will not be triggered.

Bad contacts

Damage to electrical circuits, loss of insulation integrity and disconnected contacts can lead to the alarm turning on itself at night, causing anxiety to the owner. Similar problems occur when the anti-theft system is installed incorrectly. The likelihood of damage to electrical circuits is greater in devices that can block the engine, fuel tank or ignition switch. It is impossible to eliminate such a malfunction without the help of specialists. In this case, contact a car service.

Low battery

If the battery charge is minimal, the alarm turns on constantly. Two-channel security systems with a liquid crystal display notify about a lack of energy with sound and symbolic indication. The simple system works by activating the siren. You can troubleshoot the problem by following these steps:

With the engine turned off, determine the battery voltage using a voltmeter. If a number less than 11.8 appears on the device screen, the battery should be charged. A value in the range of 12.5-13 V is considered normal.
Eliminate damage to electrical circuits. The latter lead to rapid battery discharge. Check the system using a multimeter set to ammeter mode. The negative contact is connected to the ground terminal, the positive contact to the battery. When electronic devices are turned off, use a multimeter to ring the break points. In the event of a leak, connect the system elements one by one. Normalizing the current helps to understand which part of the circuit is damaged.

Incorrect operation of volume sensors

If you choose the wrong location for installing the sensor, the sensor may be triggered by movements occurring near the car. Removing the system element and changing its location helps solve the problem. The alarm may sound if the machine is overloaded. The sensor will be triggered by a change in the amount of air, mistaking it for an attempt to steal a vehicle.

Excessive humidity

Moisture getting into the electrical wiring leads to the unnecessary activation of the alarm mode. The following reasons contribute to increased humidity:

heavy rains;
condensation observed due to a sharp temperature change (in this case, the siren is activated at night);
clogging of gutters designed to drain rainwater;
penetration of liquid into the head unit and sensors during car washing.

To fix the problem, you need to do the following:

turn off the engine;
disconnect the battery terminals;
disconnect the cables supplying the alarm head unit;
after de-energizing the on-board network, remove the housings of the sensors and control unit;
blot the electronic board with a soft cloth or brush;
dry all parts of the system using a hair dryer blowing warm air.
install parts housings, connect cables;
put the alarm in security mode.

Oxidation of limit switches

The problem often arises when installing alarms on older cars. Limit switches in this case are located on the hood, door and trunk. These parts quickly fail and begin to work even without attempts to open the lock. To eliminate the malfunction, you need to carry out the following work:

restore the correct position of the lock parts (the hinges are adjusted using a hex key);
clean oxidized areas with sandpaper;
Replace severely damaged limit switches.

Modern cars are equipped with electronic locking sensors. If the alarm does not turn off due to their malfunction, the lock blocks are replaced completely.

Electromagnetic interference in a parking area

In megacities, there is an increased intensity of the electromagnetic field, leading to interruptions in the operation of security systems. Spontaneous activation of the alarm mode is observed when the norm specified in the technical data sheet of the car alarm is significantly exceeded. The siren is triggered near mobile operator towers, power lines, tram and trolleybus tracks, and industrial zones. The only way to solve the problem is to change the parking location.

CAN bus fault

This element of the on-board network consists of a pair of cables of different levels. If a tire is damaged, the information transmitted by the sensors is lost. The alarm system recognizes such a malfunction as an attempt to steal a vehicle, which is why false alarms are observed. Troubleshooting a CAN bus requires special skills and special equipment. Similar work is carried out in service centers.

Actions of attackers

Criminal acts most often occur in the evening and at night. Due to the frequent operation of the siren, the owner turns off the alarm so as not to disturb the residents of the house. Criminals cause a false alarm trigger in the following ways:

throwing solid objects into the truck;
place special means near the car that contribute to the occurrence of radio interference and vibration of the car.

Experts recommend not disarming the alarm system in case of criminal acts. You can solve the problem in the following ways:

turning on a quiet mode that is not accompanied by a siren;
disconnecting the cable going to the siren.

The choice of security systems equipped with an engine blocker and an alarm light indicator helps protect your vehicle from theft.

Features of problems with alarms from different manufacturers

The reasons for false alarms may vary among anti-theft systems from different manufacturers.

Starline A91

Starline car alarms often go off due to improper installation or loose parts. The operating principle of the sensors is based on the early occurrence of a sound pulse. To prevent A 91 from triggering spontaneously, you need to adjust the sensitivity of the sensors. To do this, perform the following steps:

Tomahawk 9030

The Tomahawk car alarm may turn on spontaneously due to the following reasons:

Installation of sensors on plastic parts. When cooling, this material creates vibration, to which the anti-theft system reacts. Installing sensors on a metal part of the body helps fix the problem.
Incorrect timer setting. In this case, the siren starts to turn on at certain intervals. Resetting the settings helps solve the problem.

Sheriff

The Sheriff security complex is often activated, especially in the following situations:

Rain getting on the hood (when installing the system under the steering column). In this case, it is recommended to move the sensors to the middle part of the body.
The lamp is set to activate when the doors are opened. If this part of the system is equipped with a diode, the anti-theft agent will stop responding to interior lighting.

Alligator

A common reason for the spontaneous activation of the alarm mode is the increased sensitivity of the sensors. If after adjusting the indicator the problem is not solved, you need to move the sensors and evaluate the condition of the limit switches.

Pantera

The cause of malfunctions in this anti-theft system is the breakdown of the limit switches. The contacts of these parts oxidize, so their condition should be assessed and cleaned. If the Panther security complex reacts to passing vehicles, you need to change the sensitivity of the sensors. After this, the car is put on the handbrake, the on-board network is de-energized and electrical circuits are diagnosed, checking the connections.

Sherkhan 5

If the Sherkhan Magikar system falsely triggers, you need to do the following:

disable additional functions;
clean the door limit switch contacts (replace parts if necessary);
check that the system is installed correctly (false alarms occur if only the car doors are equipped with sensors).

Pandora

If the alarm mode is triggered frequently, you need to evaluate the operating conditions of the security system. Spontaneous operation occurs in frosty weather. A malfunction may occur when the key fob is placed near the steering column or the system is connected incorrectly.

Advantages and disadvantages

The main advantages of the Starline car alarm include:

Support for a large number of useful functions that ensure maximum safety and comfort of operating the machine. These include: feedback, autorun programming, etc.
Possibility of remote engine start.
The use of GSM communication channels to send important information about the condition and coordinates of the vehicle from anywhere in the world.
Availability of a CAN interface. Due to the presence of this element, the process of connecting the “signaling” is greatly simplified. The user will not need to be connected to the standard electrical network.
Low power consumption. With an extensive range of functions, the system consumes a small amount of electricity and is not afraid of wear. Battery life reaches 60 days.
Availability of a detailed instruction manual. Having studied it, the user can independently change the alarm settings or reprogram it for himself.

As for the shortcomings, there are few of them. First of all, this is the lack of stability of autostart operation in the presence of a standard immobilizer. To fix problems, just use the blocking bypass module. Users also point out poor signal reception quality, although the manufacturer claims different information.

Actions if there is no response to the key fob

A common mistake made by owners of modern alarm systems is to frequently press the key fob buttons when the alarm does not respond to them (for example, in a supermarket parking lot). The fact is that StarLine alarms perceive frequent messages that are not recognized as correct due to interference, as code grabber attempts, and block reception for a while: by trying to perform the same action several times, you are interfering with yourself.

How to set up an alarm?

Setting up the alarm comes down to setting the correct level of its sensitivity and perception of the sensors. It is recommended to stick to average settings, as choosing too high values leads to reactions for no reason.

Before you begin to eliminate the causes of spontaneous alarm activation, you should de-energize the battery to avoid a short circuit.

In budget-class security systems, in order to set up an alarm, you need:

Set the sensor location. Very often it is mounted between the front seats, immediately behind the handbrake.
Reduce sensitivity by rotating the special regulator on the sensor in its upper part. To set the correct values, you can hit the body several times with different forces to determine the level of its perception.
If no changes occur, it is enough to reboot the sensor by turning it off and then on again. After such actions, it should resume correct operation.

More expensive alarms are configured through software on the central unit, into which the sensor is built. To set the sensitivity level, the instructions and the key fob are enough.

In most cases, you need to do the following:

Disarm the alarm from the “Security” mode.
Select the “Programming” mode on the key fob.
Simultaneously press the “C” and “N” buttons on the key fob (the letters on the keys may be different depending on the model).
Set the sensitivity halfway between complete deactivation and the maximum value.

Semi-automatic alarm settings allow you to select the optimal sensitivity level. The sensor is activated in learning mode, after which you need to hit the car with different strength and frequency. This information will be remembered by the computer and will be used in the future to recognize impacts.

Price of shock sensor alarm Starline A91

The average cost of the SS 205 sensor intended for the Starline A91 anti-theft device ranges from 400-500 rubles. Used options can be purchased for a hundred rubles cheaper.

Very often, owners of cars that have previously installed the Starline security system are faced with the problem of “false” activation of the alarm system. And it seems that the installation was recently purchased, and it seemed to work properly at first, but the Starline alarm’s shock sensor still goes off at those moments when there is no one around the car. Naturally, such cases cause a lot of inconvenience, and even a false signal causes stressful emotions.

We have already written why the alarm sometimes goes off, but in this article we will try to figure out how to protect ourselves from such a fate, as well as correct an existing problem situation. This material will contain the most common causes of false alarms of the sensor, their detailed analysis, as well as ways to solve this common problem.

If you suddenly have a problem and the starline alarm shock sensor suddenly goes off, you should understand the situation as much as possible and try to find the harbingers. Is the alarm triggered by cars passing nearby or not? Does the alarm go off regularly or not, and if not, at what time of day? Sometimes there may be cases when drivers noticed that the “starline” was activated at those moments when the handbrake was on. Having dealt with the harbingers and understanding the root cause of the signal, you can understand the very essence of the problem and eliminate it.

The most common problem with false positives is an incorrectly configured system. An exclamation from the car service employees who installed the protective platform: “as soon as they installed it, it worked! This means you damaged it yourself...” are inappropriate in this case, since most often errors in the installation appear just after some time.

Increased sensitivity of sensors can be corrected on your own if all precautions are followed and generally accepted rules are followed. Setting up the starline shock sensor can help in cases where the design of the sensors and communication module has been damaged. Such situations are caused by damage or prolonged wear of protective systems.

The sensor and communication module loops can be located close to each other, while intercepting radio waves emanating from them and triggering a signal. In this case, try to separate them to an acceptable distance. Another common case may be improper fastening of the starline platform itself. The plastic material used, as the main fastener, can be damaged due to deformation from impacts, or the influence of elevated temperature. Therefore, you can get rid of false alarms by replacing the mount with a metal base.

Very often, drivers complain about the alarm going off during “wet” weather: rain, fog, snowfall. The key fob displays a message about the car being broken into, or the door being hit. The main reason for this phenomenon is said to be moisture getting into the circuits, which then short out. To get rid of the problem, you should find out in which of the locks the condensate is causing the reaction, and isolate it from moisture.

In addition, most violations can simply be caused by poor quality goods reaching you. “Long-livers” can be checked in a simple way: in the sensor settings, reduce the sensitivity to minimum. Usually in such situations the signal is too early to pass through, and such sensors must be replaced with serviceable ones.

Ways to eliminate false positives

A car anti-theft alarm is a fairly complex electronic system, equipped with a central control unit and several sensors. Failure of any component can lead to false activation of the protective system.

Before you begin troubleshooting, carefully read the instructions and evaluate your strengths. Any unqualified disassembly can lead to repair of the anti-theft alarm or its failure. Calling a car service costs much less than buying a new security car alarm.

The easiest way to troubleshoot sirens, hood switches, doors, and trunk. It is quite easy to check the reaction to humidity of the alarm siren, which is located in a visible place under the hood of the car.

To do this, with a working siren, you need to disconnect the wires, wait for them to dry (or dry them with a hairdryer), and connect the horn to the security alarm.

When the door switches become oxidized, the alarm goes off on its own, perceiving the broken contact as an attempt to open the doors. In order to remove the malfunction, you need to disassemble the mechanism, clean the contacts, oxidized, rusted surfaces, and check the integrity of the electrical wiring.

You should only undertake disassembly of the door mechanism if you have full confidence in your abilities and experience in car repairs. Incorrect installation of the mechanism will leave the door open until you visit a car service center.

The reasons why the alarm system “Tomahawk”, “Cyclone”, “Convoy” goes off on its own are explained in the video:

You can watch a video about independent work:

The ability to independently adjust the interior sensors depends on your qualifications and the specific model of anti-theft alarm installed on the car. Some sensor models are equipped with a rotary adjustment knob, others are assembled in a one-piece housing. If you were not present when the alarm was installed, it is not easy to find the sensors in the cabin; when installing the alarms, they are masked.

To adjust the regulator (usually installed in the middle position), you need to rotate the wheel in the direction indicated by the pictogram on the case. The correct sensitivity setting of the sensors can be checked by light blows to the body, doors, windshield and side windows of the car.

It is not recommended to repair damage to the sensor board or internal short circuits yourself.

Working with electronics requires knowledge of a specific alarm system, special tools, and testers. It is better to entrust such operations to experienced service organizations. For most car enthusiasts, the easiest way is to contact a car service that installed the alarm.

A properly adjusted security alarm after qualified repairs will not cause you unnecessary worries and will ensure the safety of your car.

How to avoid incorrect alarm operation

To avoid incorrect operation of the alarm, you must adhere to the following recommendations:

Correctly set the alarm sensitivity.
Properly install the anti-theft system. To do this, the wiring is hidden in a corrugation, the contacts are covered with electrical tape, and the unit is installed in a dry and clean place. The optimal location is under the dashboard, closer to the passenger seat.
It is good to fix the control unit.
Select the appropriate type of security system software for a specific car model.
Carefully monitor the condition of the vehicle's electrical wiring.

It is worth remembering that if problems arise in the operation of the alarm due to poor-quality wiring, warranty service is not provided.

Foreign things in the car

Modern car alarm models have the option of configuring the interior volume sensor. Large items left inside the car may cause the alarm to go off.

When setting up a volume sensor installed in the car interior, you should take into account the likelihood of the presence of foreign, large objects in the car.

There have also been cases of incorrect settings of volume sensors in the car interior. When the sensitivity of the sensor settings is high, the car alarm starts to trigger on insects that remain in the car interior. Motorists could only drive out all the flies from their interior before arming the car, or they still had to set up the sensors correctly.

Having identified malfunctions, they begin to eliminate them. We remind you that the main sources of abnormal activation are: sensors; Limit switches; connecting elements of the electrical circuit. The possibility of influence of weather conditions cannot be excluded.

If a car alarm goes off on its own, there is a risk that the owner of the car may not get inside the car, or if the alarm signal works for a long time, the battery will be completely discharged.

Pressing the key fob button

Why does the alarm sound?

There are several main reasons when the alarm may turn on randomly:

The alarm or sensors are faulty. In this case, it is better to contact a service center, since only a specialist can accurately diagnose the problem. In addition, if the installation is not under warranty, the problem will be fixed free of charge.
Some drivers install an internal volume sensor in the cabin. If you leave a large object in the cabin, then if the sensor is incorrectly configured, the alarm will go off constantly.
The car alarm may be triggered due to a malfunction of the limit switch - part of the system that serves to close the circuit that turns on the alarm when the hood, doors or trunk are opened. The malfunction can be identified by the illuminated open door icon on the alarm key fob. The limit switch may not work correctly if the contacts are oxidized, worn out, or due to wiring problems. In the first two cases, it is advisable to replace the element, although cleaning the oxidized contacts may help for a while.
The alarm often goes off in wet weather or after washing. Moisture enters the system and it trips. In this case, you should disarm the car and wait for the system to dry out. After this, you can arm the car again.
The sensors are not configured correctly: their sensitivity is set too high. The sensor, which is triggered by the slightest vibration of the machine, must either be reprogrammed or its sensitivity adjusted.
Most often, water gets on the end switches of the hood, doors and trunk, as a result of which the alarm system begins to work.

Connecting door switches

In what cases is it better to contact a specialist?

Instructions for operating and setting up the Starline A93 alarm
First of all, if the standard alarm goes off on its own, when assembling a car on a conveyor belt, it is easier to “hide” the alarm unit, and its wiring is naturally integrated into the standard wiring harnesses, which makes it difficult to “ring” and repair. Security systems installed after purchasing a car have recently often had a modular structure, distributed in different places, which complicates the task of troubleshooting. In addition, errors in the operation of the alarm unit can be caused by malfunctions of the electronic elements of the engine control system, the operation of which is blocked by the security complex. To identify the cause, a detailed diagnosis of all engine control systems (sometimes gearboxes) is required.

Modern car enthusiasts are afraid for the safety of their vehicle - now it is difficult to find a car that is not equipped with anti-theft protection. At the same time, in recent years, many inexpensive Chinese devices have appeared on the market, which are purchased and installed in budget cars. Such solutions do not have any special security functions, but they greatly irritate the neighbors. Many owners of such car alarms complain about false anti-theft alarms. Yes, such a phenomenon exists. To verify this, you can simply read any automobile forum. Let's try to find out why the car alarm goes off for no reason. After all, if the siren goes on late at night, when everyone is dreaming, it will not be very pleasant. For this, “grateful residents” may even take revenge - for example, by puncturing a tire. And the owner of such a car himself will not be able to get a good night’s sleep before the next working day - when the alarm siren goes off, the owner immediately rushes to see if everything is okay with the car. And if there are 5-10 of them, then you simply won’t be able to fall asleep and get enough sleep. Turning off the alarm is also not an option, because the car will be left unguarded, and it is unknown what could happen to it at night. Gasoline is often poured out in yards, wheels, mirrors, wipers are stolen, and cars are simply stolen.

What to do if the StarLine alarm does not arm

Sometimes a Starline car alarm can malfunction and cause problems for its owner. Among the most common complaints.

The alarm does not pick up at 20 meters and does not go off. The reason why the car is not disarmed may be a bad signal. In this case, the car simply does not have feedback from the key fob, and accordingly, it does not perceive commands. In this case, you need to check the condition of the power supply element of the remote control, perhaps precisely because of the weak signal, and replace the battery if necessary. Additionally, you need to check the area for radio interference;
There are also options when the siren goes off spontaneously. The reason for this behavior is that the shock sensor is too sensitive. Both stages (impact and hacking) can be adjusted using a standard screwdriver, reaching the sensor itself (it has special controls);
Sometimes autostart with automatic transmission does not work on the car, and SP lights up on the key fob display. This means that the car tried to start the car four times, but the starter simply did not have enough force. It is recommended to start it manually or increase the duration of its operation. In this case, for autostart it is necessary that the car is in neutral and the parking brake lever is fully tightened;
If the alarm does not work, and additional software errors appear (the car starts and stalls, does not close the doors, etc.), then it is best to reset to factory settings. After this, most of the problems should disappear, but if they cannot be fixed, then it is better to take the car to a specialized service, where qualified specialists will sort out the issue and fix all the problems, perhaps there is a mass loose or there is a bad contact somewhere.

Pros and cons of automatic start technology

Like any other device, autostart for a car without an alarm has its positive and negative sides. Its obvious advantages are:

Complete preparation of the engine for operation in advance. By the time the driver hits the road, the engine will already be started, brought to operating speed and warmed up. You don’t have to waste time and go straight away - and in the winter season this saves a lot of time.
Comfortable conditions in the cabin. The heating system or air conditioning usually starts together with the engine. Thus, by the beginning of the trip, the inside of the car is already warm or cool, depending on the time of year.
Autostart is indispensable on trucks, where frozen hydraulics can damage the entire vehicle.

However, there are also disadvantages, and quite serious ones. They are:

Vulnerability

Automatic start of a car without an alarm system attracts the attention of car thieves or thieves - and you can lose either the car or valuables left in the cabin. Operation of the engine together with an alarm and immobilizer is usually impossible

Therefore, you can use the device without an alarm only in a guarded parking lot, or when the car is in the owner’s field of view. Excessive fuel consumption. The electronic unit must be carefully configured; without this, it will drive the engine at those speeds that it considers normal. In addition, starting by a timer or temperature sensor will cause the machine to turn on itself, even when it is not required. This problem is solved by correctly configuring the sensors and programming the unit itself. Winter autostart in a parking lot often leads to freezing of the muffler, in which condensation accumulates. To avoid this, you need to set a limit on the operating time of the motor. In practice, about 10 minutes is enough, after which the engine can be turned off. Without a gear sensor, automatic starting is dangerous: if the driver forgets to put it in neutral or does not apply the handbrake, the car may well roll away. In the past, it often happened that the driver accidentally pressed the autostart remote control in his pocket when the car, for example, was standing at a traffic light with the gear engaged - and without his participation the car was thrown into red. The only method to solve the problem is to use high-quality sensors.

Unlock methods

Having installed an external alarm system, for example, Starline, it is advisable for the car owner to carefully study the instructions for the rules of its use and operation. The instructions also contain tips on what to do if there is a malfunction in its operation.

The easiest way to unlock an external alarm is to re-close the car doors. To do this, get out of the car and close the door tightly. Then turn on the remote control to arm the car and wait about ten seconds. It is during this time that the car is armed. On some types of alarm systems, the arming process takes longer, from one to two minutes. Open the doors again using the remote control and try to start the engine. If the failure occurs due to the door switches, hood, or trunk lid, then the car will start.

An attempt to return parameters to factory settings using the key fob can work effectively. Due to the fact that there are very many types of alarm systems installed on cars, and at the same time the settings algorithm is also varied, resetting parameters and returning to factory settings must be carried out according to the instructions.

Situations arise when the central unit does not respond to commands sent by the key fob. In this case, you can use the Valet service button. The button may be located in a secluded place, where the hijacker will not find it and it will take time to find it through the wires.

The location of the Valet button is indicated in the description, but often installers choose its location at their own discretion. It is recommended that after installing the alarm, you check with a specialist in what place he placed it. Forgot to ask or bought a used car, and then there were problems with the signaling. No problem - the service button is easy to find along the wires coming from the central unit.

If the alarm system is blocked so that not only the engine does not start, but the doors do not open, then you need to open the door lock with the key. Opening the door will automatically trigger a loud sound alarm, which can be turned off by disconnecting the terminal from the battery. Using the dialing method or using a diagram, the terminal numbers on the central unit and the color of the wires are determined. Using this information or visually using wires with the corresponding color, we find the location of the button.

Switching to service mode (or unlocking) is individual for each type of anti-theft system. Therefore, how to use the Valet button is described in the manufacturer’s instructions. Basically, all actions are almost the same for most types of alarms.

Here is an example of Starline deactivation:

Open the car with the key.
Turn on the car's ignition and press jack three times (time limited to 20 seconds).
Turn off the ignition.
The siren will sound and the emergency lighting will turn on at intervals.
Starline deactivation is complete.
Start the engine.

What to consider

When adjusting, you should take into account the weight of the car, methods of mounting the control unit, and parking features. To reduce sensitivity, lower the response threshold using the remote control, and then check it with light strikes of the palm of your hand on the body. This is how the level of physical impact is determined. For greater accuracy, the car is armed and left for 2-3 minutes. Only after this time can you lightly knock on the center of the windshield. The main inconvenience of such settings is the need to set and disarm the car several times. In addition, you should prepare in advance for the siren to sound approximately 10 or more times.

This is usually not related to the car model and alarm malfunction. This is due to VIOLATION OF THE RULES FOR INSTALLING THE ALARM. Very often people do not read what is written in the instructions or do not care about the recommendations, thinking - I always did it differently - it was easier and faster for me and everything worked - I won’t bother. And then problems. 1. It is necessary to lay the communication module cable (black five-wire noodles to the box with horns on the glass) SEPARATELY FROM OTHER WIRES, especially from the shock sensor cable (four-wire noodles red-white-blue-black) Read here viewtopic.php?f=33&t= 3382 This is for the C-series, but for the dialogue A91, A92, B92 with a remote shock sensor and younger sisters without warming up, this has become even more relevant. 2. And to prevent this from happening when starting the engine and turning on the service relays, all relays installed additionally must have shunt diodes placed parallel to the relay windings. 3. Another reason could be: recorders/navigators/FM modulators and other baubles. More precisely, their Chinese power supplies are “emitting” interference into the air. Do you have nothing left powered during the period of protection of such “gadgets”?

And the last thing - in general, the cables of both the communication module and the shock sensor should be laid as close as possible to the IRON elements of the body and as far as possible from the standard wiring, alarm wires and each other. These are the rules of good manners during installation. You will have to catch fewer glitches and redo them in the future.

Setting up periodic autorun

Periodic autostart for Starline E90 starts from the moment the corresponding mode is activated (“Hourglass” or “Thermometer”). Once the appropriate icon is selected, the key fob will display the current periodic launch setting:

https://youtube.com/watch?v=G2UOKsmmnyo

For the “Hourglass” you can set an interval from 4 to 24 hours in 2-hour increments; the options change cyclically by pressing button 1.
For the “Thermometer” you can set the temperature from -27 to -3 degrees in increments of 3 degrees.

Having selected the desired value, long press button 1. A few seconds after this, the engine will start for the first time, further starts will take place according to the settings until the periodic start is turned off.

At the same time, it is by no means necessary that at the time of autostart the key fob has a stable connection with the central alarm unit. The same applies to auto-start on an alarm clock, which is a serious advantage in comparison with alarms, where the key fob issues the start command every time.

Increased sensor sensitivity

The sudden activation of a car alarm is due to incorrect adjustment of the sensors.
The settings of the elements responsible for the response to impact are performed poorly, with a high level of sensitivity. This is especially true when there is heavy traffic nearby, creating vibration. Shock sensors mounted on the vehicle are triggered, notifying others with loud signals, causing panic among the owners. The problem that arises is solved by reducing the susceptibility of car alarm sensors responsible for reacting to an impact. Before making adjustments, it is recommended that you thoroughly read the operating instructions. Installing a security device on a vehicle has many nuances. Our experts will tell you how to properly adjust the sensitivity of shock sensors.

You can perform this elimination operation yourself. Independent elimination is fraught with certain difficulties. This is especially true when reconfiguring car alarms of an earlier generation. In such car alarms, to prevent unauthorized operation, the sensitivity is adjusted mechanically.

In modern models installed on a car, sensitivity is adjusted electronically. To be on the safe side, you should engage the service center of the company that installed the security system on the car. Adjusting the sensitivity is accompanied by the activation of a car alarm and the periodic activation of a warning light.

The problem of alarms going off for no reason is often exploited by car thieves. At night they shake the car so that the alarm goes off, and they hide. The car owner looks out the window, the car is in place, the reasons for the alarm are not visible, then the car is armed again. The thief again loosens the car, and the car owner repeats his actions. This happens many times. The neighbors start screaming because it’s night outside and the alarm is going off making it difficult to sleep. After several alarms go off, for no reason in the owner's opinion, he disarms the car or puts it on silent, after which the thief opens the car without fear that the sounds of the siren will wake up the owner and he steals the car.

To prevent theft, the owner of the car should not immediately go to bed after the alarm goes off, but wait and see why the alarm goes off, or you can immediately drive the car to a safer place, for example, to a guarded parking lot.

Differences

There are differences on older systems - in this case, the sensitivity threshold is adjusted not by electronics, but by a special screw. To reduce it, the element is rotated counterclockwise. On more modern models, buttons are used instead. The scale has several levels, which indicate the degree of response of the device. Standard adjustments are level 5 out of 10 possible on most systems. During the setup process, you should not increase the sensitivity too much, because the security device can only be triggered on average 10-12 times per cycle.

After this, the system is re-armed and then the configuration continues.

Where are the sensors located?

Starline A93 shock and tilt sensors are located in the antenna module. It receives and transmits the signal. The module is installed on the windshield away from the alarm control units. The sensitivity of devices is also affected by the location of the antenna. Therefore, to change the parameter, you can try moving the module across the windshield.

Temporarily disabling the tilt sensor

How to turn off the Starline A93 tilt sensor - press key 3 twice. To turn it on, just do the same.

5.1. Video of turning off and turning on the A93 tilt sensor

5.2. What is dh off, dh on on the key fob

When working with a tilt sensor, it will be useful to know what dh off and dh on mean on Starline A93. The inscription dh off means a temporary shutdown, and dh on means the sensor is turned on. The first inscription is displayed on the key fob screen when you press button 3 twice for the first time, the second, respectively, when you press the same button for the second time.

Autostart based on temperature and time

However, there are more convenient ways to control autorun. On diesel engines, which consume practically no fuel at idle, the best option for autostart is to independently maintain the temperature. In this mode, the alarm constantly polls the engine temperature sensor and, as soon as it drops below the set value, starts the engine for the time specified in the settings. When the engine stalls, the same cycle starts again, and after cooling to the limit temperature, the StarLine A94 will autostart again.

To enable periodic autostarts based on temperature, place the cursor on the “thermometer” icon and press button 3. A melodic signal will sound and the screen will display the current temperature at which autostart occurs. Now, if necessary, you can change it by short presses of button 3; the permissible range is from -3 to -27 degrees.

You can run the engine cyclically and on time to prevent the car from drying out overnight. The principle of operation is the same, but the cursor is placed on the “alarm clock” icon. After briefly pressing button 3, the screen will display the current value of the time interval through which startup attempts are made. Short presses of button 3 change this interval from 4 to 24 hours.

However, the cold weather passes over time. How to disable timed autostart of Starline A94 if it is no longer necessary? Move the cursor over the “alarm clock” icon and press button 2, similarly with temperature triggering - only the “thermometer” icon is used.

This is where the benefits of telematic alarm control come into play: to manage these parameters, go to the settings menu of the mobile application.

You can immediately set a set of conditions: for example, periodic startup every 4 hours if the temperature is not higher than -3 degrees. Compared to programming autostart conditions through the main key fob, this is both faster and more intuitive.

Finally, how to choose autostart for a car without an alarm? The rating of this kind of systems distributes prizes as follows:

Pantera SLK-868RS - fifth place, the ideal combination of price and quality.
StarLine A91 - fourth place.
Scher-Khan LOGICAR 1 - third place. Very good functionality, the module is relatively easy to install.
Pantera SLK-675RS - second place. Excellent functionality and high reliability for quite reasonable money.
And again StarLine: the A94 model is beyond any competition. Excellent functionality, reliability and ease of installation. And a price that is lower than competitors' offers.

Here's how to choose an autostart for a car without a 2014-2015 model quite clearly shows the most “bright” and reliable representatives of the market.

Carburetor cars are still in great demand in the secondary market today. Therefore, installing autostart on a carburetor is a fairly pressing topic. With carburetor cars, serious problems often arise when starting from cold, especially at extremely low temperatures below -25°C. In this article, we will look in more detail at how autostart is installed on a carburetor using the example of a domestic VAZ 2107 car.
