Starline A91 shock sensor: how to disable it, sensitivity settings

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. How to disable automatic activation of Starline security.

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 second key fob is connected in exactly the same way as the first.
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.

The control unit is used to adjust the sensitivity of the sensors.

Connecting the key fob

For the Starline A 91 alarm to work correctly, it is necessary to connect the key fob to the vehicle’s electronic security system.

Connection is made in the following sequence:

To carry out the registration process, you need to find the “Valet” button (in the fuse box, under the steering wheel or glove compartment) and press it 7 times to activate the system with the engine off.
Turn on the ignition. The siren should sound 7 times if all operations are completed correctly.
To do this, we activate the key fob at the same time, press buttons 2 and 3, as a result of which one siren signal should sound, signaling that the key fob is connected.
We connect the second key fob in the same sequence.

The correct operation of the Starline alarm is influenced by 3 main reasons;

adjusting sensor sensitivity;
installation location;
correct fastening of sensors and signal unit to the car body.

The sensitivity of the sensors can be adjusted using the control unit.

How to disable

Disabling the shock sensor is used to reduce the number of false alarms caused by external factors. At the moment of remote or automatic start of the power unit, the security complex turns off the sensor, since vibration from a running engine is perceived by the sensor as an attempt to penetrate the vehicle interior. When setting the operating parameters of additional channels, it is possible to set a parameter that temporarily disables the shock sensitivity sensor.

To disable the shock sensor on Starline A91 or A93, you will need to press the remote control button, indicated by the closed lock icon, twice. The car will respond with a double signal from the external light alarm, the key fob will give a melodic signal, and the text DAT1 will be displayed on the display, indicating a temporary disabling of the warning sensitivity level. When you press the button twice again, triple signals are sent by lamps and a buzzer, and then the alarm level is turned off. A text like DATE2 appears on the display.

The car owner can turn off the sensor by turning the sensitivity control to the minimum position. On the A93 complex, you need to set the zero value through the setup menu. It is not recommended to disconnect the shock sensor on the Starline A91 by disconnecting the cable harness from the processor unit.

Basic alarm faults

Most often, motorists have to deal with malfunctions that arise during the operation of the Starline A 91 car alarm:

When you press the key fob control buttons, the alarm does not go off (you need to replace the battery, replace the key fob).
A false alarm occurs (the settings of the alarm sensitivity unit need to be calibrated).
When you turn on the car door locking mode, a malfunction occurs (the reason may be a malfunction in the alarm system or the locking mechanism).

How to set up a shock sensor for a Starline A91 alarm using a key fob

Starline A91 has piezoelectric elements with regulators that are adjusted using a screwdriver, which is used to rotate them clockwise. In order to correctly adjust the parameters, follow the explanations drawn on the body of the gadget - they indicate the direction of movement to decrease or increase sensitivity. Additionally, green and red LEDs help in determining the moment of operation.

Sensitivity can also be adjusted using key fobs that serve as control panels. Each of them has a display with a two-way communication unit. During autorun programming, additional settings are made. In particular, it is set to ignore a running motor or starter at the moment of rotation.

Full adjustment of the sensitivity of the Starline A91 system sensors looks like this:

The first step is to turn off the car's ignition and security mode.
Next, click on the button adjacent to the one on which the round icon is drawn.
The success of the actions taken will be indicated by two activations of the alarm siren and triple flashing of the headlights.
In turn, the key fob emits a melodic signal and its indicator displays an indication of what level of the sensor warning zone is already programmed: by default it is 10.
Now the car owner can independently specify the desired parameter in the range from 0 to 14. To do this, he uses buttons with triangular icons on the remote control.
To adjust the level of anxiety in the car, hold down the same key as in the second point until a sound signal appears. After which they press it a second time, but for a short time.
If the action is successful, the already set sensitivity value appears on the display, the default value being five. It is adjusted in the same way as the warning zone.
Saving the settings occurs by holding down the signal and pressing the same key again as above.

The success of the manipulation will be indicated by three activations of the siren and three headlight signals. The preset melody will also sound on the remote control.

How to turn on the shock sensor

How to increase sensitivity

The sensitivity of the anti-theft system is adjusted using the above-mentioned regulators, which are turned with a screwdriver all the way counterclockwise. As for adjusting the warning level, for this the corrector is turned by a third.

You can adjust the sensitivity only when the security mode is turned off. The car door must be open. After each turn, the force on the body at which the sensor is triggered is checked. To do this, light blows are applied to the body cover or its central pillar.

The correct operation of the reconfigured sensors is checked when the security mode is turned on. After activating it, wait up to a minute for the sensor to work with the new settings.

As for the increase in the alarm level, this follows the same procedure. It is important to remember that the alarm level value cannot be less than the warning zone. Otherwise, the sensors will not work correctly.

How to reduce sensitivity

The sensitivity mode value is set with the security activation button. The car owner can either completely turn off the sensors by setting the value to zero, or temporarily reduce it only while the power plant is operating. Test runs and warm-ups of the latter are used to determine whether the adjusted level is suitable.

Saving memory parameters is carried out through the same button presses as when entering the settings menu for additional channels. After this, turn off the ignition. The success of the manipulation is indicated by three flashes of headlights and a triple sound of a siren. At this time, the programmed value appears on the remote control, after which it goes into the standard time display mode.

How to disable the Starline A91 shock sensor

The need for shutdown arises from the increased frequency of false alarms due to external factors.

The most common such factor is remote engine start - vibrations from it are perceived by the installation as an attempt to penetrate the vehicle interior. Therefore, it is most important to temporarily disable the sensor at such moments.

The Starline A91 shock sensor is turned off by double pressing the button on the key fob, indicated by the closed lock icon. In response, the external light alarm of the machine will flash twice, and the remote control will emit a melodic sound. The DAT1 parameter will be displayed on the display of the latter, indicating that the warning sensitivity level has been temporarily turned off.

To turn off the alarm level, you must press the same key twice again. The headlights and siren will respond with a triple signal, indicating the success of the manipulations. The DATE2 parameter appears on the display.

The mechanical method of turning off the sensor involves turning the sensitivity regulator with a screwdriver to the minimum level. You can also set the level to zero in the setup menu. In this case, it is strictly not recommended to disconnect the sensor by disconnecting the wires.

Signal sensors

To accurately trigger the Starline A 91 alarm, it is necessary to fine-tune the trigger modes of the shock sensor in the event of an unauthorized attempt to gain access to the car by unauthorized persons.

Modern alarm systems are equipped with 3 types of sensors installed on cars:

a shock sensor, which is triggered by vibration of the car body when a set threshold value is exceeded;
movement sensor, gives a signal when there is an attempt to steal or evacuate a car;
volume sensor, is triggered when an attempt is made to enter the vehicle interior.

Correct configuration of sensors ensures reliable vehicle security and eliminates false alarms.

What are they for?

Starline shock sensors are a key element of any modern alarm system, including Starline A93. Its functions include vibration control and signal transmission to other devices, for example, the central unit. When the Starline A93 sensors are configured correctly, the latter quickly respond to impacts and notify the owner of the negative impact on the car.

The principle of operation is based on a control magnet mounted on a metal spring. At the moment of impact on the car, the spring is triggered. In this case, an electrical signal is generated, and the alert level is determined by the force of the impact. The new devices have a 2-level sensor that detects mechanical impacts and immediately transmits information to the owner.

Setting sensor sensitivity parameters

When adjusting the sensitivity of the shock sensor, it is necessary to determine exactly what is causing the false alarm.

The main factors may be:

the alarm level is set to high;
The alarm unit and sensor are installed in the wrong place or are poorly secured to the car body.

It is necessary that the shock sensor be attached directly to the car body, have a strong connection and be mounted in strictly recommended places.

To check and configure the functionality of the Starline A 91 system, you must perform the following operations:

disconnect the car battery terminals or remove the fuse responsible for the interior lighting (this operation is necessary to prevent the battery from discharging);
we find the installation location of the shock sensor (usually under the front panel, in the area of the pedals or steering column);
To configure the sensor, disable the security mode, switch to programming mode and make the necessary changes. In previously produced Starline models, adjustment was made using a special screw, and in new models using buttons;
The system sensitivity level corresponds to the setting scale and contains 10 sections, 0 – min level, 10 – max sensitivity value. The standard factory setting level is 4-5. It must be taken into account that most models have settings for 10 attempts, and for the further process it is necessary to repeat the arming operation;
when setting up, it is also necessary to take into account the weight of the vehicle unloaded and fully loaded;
When adjusting the sensitivity level, it is necessary to achieve a level where there are no false alarms.

It is also necessary after setting a new sensitivity level for 2-3 minutes. wait and then check. This period of time allows you to stabilize the level of sensitivity of the Starline system. When checking the operation, it is necessary to strike all parts of the car (windows, hood, doors, trunk, wheels).

After configuration, it is necessary to turn the security system on and off 4-5 times to confirm the stability of operation. When striking various parts of the car, the amplitude of the impacts is recorded by the microprocessor and these values are subsequently used as the threshold level for the system to operate.

How to connect

The sensor is attached to a metal body panel in the passenger compartment using screws or 2-sided adhesive tape.

It is not recommended to install the element on moving plastic parts or vehicle wiring harnesses due to a decrease in measurement accuracy.

The device is placed openly, which provides access to the rotating elements for adjusting the sensitivity of the shock sensor. The accelerometer is located together with the transceiver unit on the inner surface of the windshield (at a distance of 50 mm from the metal elements of the body).

The connection harness (consisting of 4 wires) is routed under the car interior trim. To connect to the processor unit connector, a standard harness block is used. To switch the transceiver unit, a plug with 5 cables is used; on the processor unit, the plug is installed in connector X8.

Additional alarm settings

If, after connection and configuration, the alarm system malfunctions, then it is necessary to reset all settings.

To do this you need to do the following:

turn off the car ignition, press the Valet button 9 times in a row, as a result the siren should sound (short signal) and the dimensions should blink twice;
turn on the ignition - the headlights should flash twice, and the siren should sound 9 short signals (this means that the system has entered the reset mode);
press the Valet button and hold until the siren sounds;
on the control panel, press the “speaker” button and wait for the control panel to give a signal;
To exit the reset mode, turn off the ignition, after which the lights should blink several times and the remote control should sound a beep.

After the reset, we repeat the sensitivity adjustment according to the instructions to achieve the required parameters.

I also had this problem, how to cure the f... fucking sensor? Where is he anyway? If you don’t know, I’ll find it and destroy it myself, no sleep or rest for my tormented soul))) This game entertained me all night until I extracted the resource of this attraction from under the hood... But that’s not the point, the alarm system is needed so that I I slept peacefully, but here it seemed to be there, but it was better without it... On the one hand... And on the other, the car was unguarded...

For a note I will say this; turning off the alarm with the remote control helps for a few minutes, after which the car turns on the siren mode again, I decided to set the silent mode by pressing: long the first button on the remote control and after a short beep, short the second button, an icon appeared on the display but the problem was not solved, the car did not emit a siren signal, but the remote control was torn into pieces, telling me that the shock sensor had tripped. Then I noticed that the battery indicator on the remote control showed one bar, although I installed a new, expensive battery! I put the car on silent mode, and then took the battery out of the remote control, it seemed like there was silence, you could sleep peacefully! Hence the thought, maybe a weak signal from the remote control is causing the alarm to glitch like that? Let's figure it out and experiment
