What is an autostart system for a car without an alarm?

Installing an alarm system with auto start is not always the optimal solution. If your car already has an anti-theft system installed, then there is no point in modifying it for the sake of one single function. In this case, the best solution is to install an external module that ensures autorun functionality.

Installing autostart without an alarm must meet several requirements:

1. Compatible with already installed anti-theft means - at least have the ability to bypass the standard immobilizer.
2. Flexible programming – for cars with a “Start-Stop” button, this is necessary in order to correctly simulate the driver’s actions when starting the engine. For modern cars, it is necessary to ensure correct “falling asleep” of on-board circuits, implemented through simulating the opening and closing of the driver’s door.
3. Security of the control channel: autostart without alarm must use either a secure radio channel (as in alarms) or be controlled from a mobile phone.

How to check if there is autorun?

The verification algorithm is not that complicated, follow all the steps sequentially:

1. Put the car on the handbrake, move the gear selector to neutral position.
2. Turn off the ignition; if the engine stalls, use the starter to start it again.
3. Next, on the Starline key fob, press the button with the key icon.
4. Now try to remove the key from the ignition, if you succeed, then your car has auto start. When you lock the doors, the engine will automatically stop after 30-60 seconds.

If, when you press the autostart button, you hear the engine cranking, but the engine does not start, you should check the settings. Read the security alarm operating manual carefully, then you can configure its operation correctly.

Selection of alarms and selection of tools

First of all, the car enthusiast must purchase a set of devices that are suitable for a specific car.

In order for the independent installation of an alarm system on a car to be successful, it is important during the selection process to remember the type of engine (gasoline or diesel) and the features of the transmission (mechanical or automatic). And the rest of the set of options will be determined by the level of comfort that the driver wants to receive from the alarm

For successful work, you will also have to collect a small set of tools and simple materials. Connecting an alarm system will require:

• Phillips screwdrivers;
• set of wrenches;
• sharp knife;
• lighters;
• black electrical tape;
• double-sided tape;
• multimeter;
• foam rubber.

Installing an alarm system with auto start is a rather complex process, so the average car enthusiast is better off entrusting this work to experienced specialists at specialized auto centers.

Their advantages and disadvantages

• lower cost
  . Some service stations install “clean” auto-start, functionally cutting off standard car alarms with auto-start. That is, the cost is not much different;

• reduction of abnormal electrical connections
  . This point is more effective on older cars. For new cars, the alarm connection is made via the CAN bus; the number of non-standard conductors is minimal.

Disadvantages of autostart units without alarm:

p, blockquote 39,0,0,1,0 —>

• If your car has an alarm, it will go off when you start the engine. If it is unlocked during autostart, then the car will be vulnerable to theft. It is difficult to coordinate the security mode with the engine running for different systems;

• the car becomes overgrown with various key fobs, non-standard units in the cabin, and additional wiring, which increases the likelihood of its malfunction;

• When installing a new auto-start system, it is better to simultaneously replace the old security system with a new one with auto-start. If the old alarm becomes unusable or starts to malfunction, repair will be extremely difficult.

Connection

Following the instructions from the alarm, you need to connect the following wires:

• to the button for turning on the handbrake light (without the handbrake, autostart will not work)
• to the neutral or parking sensor (to prevent starting at speed, for an automatic machine you can use a parking “indicator light”)
• according to the instructions, or at your choice, if not indicated, we connect the engine start detector (this could be a tachometer, a charging or oil pressure light, an ECU)
• connect to the brake pedal (if not connected previously)
• energize the stove or air conditioner (we recommend low speed)
• install the ignition key bypass circuit (indicated in the instructions)
• connect and hide the immobilizer bypass system well
• We assemble the relay block (according to the diagram)

Next, we program the time for turning on the starter, the pause time to determine the start and the time for the second start of the starter, if the engine does not start, if necessary, program the turn on of the stove (air conditioner)

Typical engine control system connection diagram:

Using a telephone - is it possible?

But what to do if the engine starting time is very long? A time relay must be used. But this is not always possible to implement, so it is quite reasonable to use a cellular network. In addition, this is relevant for systems that are located at a considerable distance. Even if you are in another region, it is possible to start a generator, for example, in a greenhouse, to provide heating. But you need to adhere to some requirements, which will be discussed below. Autostart must correspond to them. It’s not difficult to do everything with your own hands. You will also need to change the design of the phone used as the autostart tool.

We install autostart with our own hands

Before you begin the installation work of the autostart on the VAZ, you need to prepare everything required for this. Installing one alarm will not be enough; it will require long and painstaking work. To bring your plan into reality, you will need to prepare the following:

• alarm system with auto start, in this case you can use the simplest model from the manufacturer StarLine;
• a temperature sensor and a controller are purchased separately;
• small electric drive, can be used from a Ladovsk washer;
• a thin cable, preferably soft, made of copper or aluminum, but it is better to give preference to the copper option;
• wiring in the required quantity, it is better to prepare with a reserve;
• In addition, patience will be required, since setting up equipment and autostarting a carburetor is a long and painstaking process.

Scheme for installing autostart on a carburetor

You can start assembly by turning off the manual choke, which is installed on any VAZ carburetor engine. In this case, you don’t have to pull out the cable, but secure it securely under the hood. There is a high probability that it will be useful for something in the future. If you have an auto choke on your car, then it will have to be completely disassembled. The carburetor is completely disassembled and all sensors are removed from it. The last step before assembly is to switch the feed drive to external.

Stages of installing a do-it-yourself autostart on a carburetor

To install a start-up signal on a carburetor engine, the following series of actions must be performed sequentially:

1. First of all, all the components of the structure are placed in their places. The electric drive can be installed on the engine wall. The temperature sensor is mounted on the engine. You should not use an old sensor, as there is a high probability of making a mistake. The microcontroller will need to be placed next to the electric motor, although in some situations it is better to attach it to the carburetor.
2. Using a previously prepared cable, the engine is connected to the damper.
3. All parts of the suction pump should be connected to a microcontroller, which in turn has a direct connection to the signaling system.
4. Next comes a test test, if the system gives a response, then you can move on to the next stage, if there is no feedback in the carb, then you have to recheck the entire connection again.
5. The entire system is tested and brought to perfection. The microcontroller will have to change several operating modes taking into account the temperature sensor readings. You should also adjust the length of the cable as much as possible. Once the system has been tested, the first test run can be performed.

The final stage of installing autorun

It is possible to fully start the engine using the key fob only after installing the air damper servomotor. The device, as a rule, is placed on the wall of the engine compartment, while others, on the contrary, try to mount the element directly on the carburetor. By installing this element, you can forget about the position of the air barrier. This device is produced under the Sadko brand. The model is produced in two types:

1. Standard equipment, which includes a microcontroller, control unit, cable, electric drive and temperature sensor.
2. The maximum configuration, which contains all the previously listed devices, as well as some additions.

The maximum configuration of "Sadko" is distinguished by the following indicators:

• Having received a signal from the alarm key fob, the damper automatically opens slightly;
• Next comes fuel injection;
• after which, due to the control unit, a spark is supplied, which starts the engine for warming up.

If you decide to give preference to the standard set, then you will have to manually configure the entire system, since there may be a problem due to inaccurate calculations and installation, namely:

• The ignition is turned on first and the damper is closed manually;
• after the engine is running normally, you have to close the damper again with your own hands;
• after waiting for some time, you have to completely open the fuel supply;
• the machine should run for some time at idle speed without outside intervention;
• At the end the engine stops and cools down completely.

Upon completion of everything, all that remains is to test start the car with a button from a certain distance, which is accessible for the alarm.

Homemade autostart systems

Recently, the topic of self-assembly of autostart systems has been popular, primarily due to the availability of Arduino-like modules and expansion boards for them, including relay units (simulate the operation of the ignition switch) and GSM modules for control via SMS.

However, such homemade products are primarily the domain of qualified radio amateurs, and you should not blindly repeat designs from the Internet. First of all, because the safety of such systems, unlike factory autostart modules, is not tested by the creators: the likelihood of seeing your car ramming your neighbors in the morning outweighs the pleasure of creating a useful device with your own hands.

System requirements

The most important thing is to limit the circle of people who can call the phone used in the autostart system. You need to prohibit receiving messages and calls from all subscribers except one - the number that you plan to use for management. Even the “don’t tell anyone the number” option won’t help, since it could have been used by someone before. And you don't want your car engine or generator to start on false commands.

It’s not very difficult to do GSM autostart with your own hands. It will be more difficult to secure the mobile number used in the system from outside calls. But this can be done by contacting your mobile operator. It is worth noting that the diagram may differ depending on what model of car or generator you plan to drive. It all depends on the complexity of the ignition system.

Best modules

Today, the market for auto parts, accessories and electronic systems offers a wide selection of autostart modules. Among other modifications, it is necessary to highlight AlarmStart GSM. Such a module costs 29,900 rubles. This is a universal kit that allows you to activate the internal combustion engine using a key fob or mobile application. The system is completely autonomous and does not require integration with an alarm system. It works independently of different automotive technologies. You can launch such a module with a phone call. Commands are also received via SMS messages.

Car owners will be able to activate the function by pressing the corresponding button in the mobile application. AlarmStart GSM also has a programmable timer, which can be adjusted depending on the wishes of the owner. This kit is suitable for any make or modification of car.

No less interesting is the AUTOLIS Mobile

(RUB 29,600). This module is equipped with an Italian-made GSM modem. It is necessary to note the presence of a voice interface. Consequently, owners of this kit will be able to give voice orders. Has equipment and an SMS alert option. Commands can be issued online.

The module is reliably protected from hacking attempts via GSM communication. The same GSM system is responsible for setting coordinates while moving through unfamiliar terrain. You can control such a module using any modern gadget.

The module is configured according to the individual needs of the car owner. Each user will be able to choose the method of notification and autostart of the internal combustion engine. Performs a set and function of a car alarm. It will notify the car owner of any danger in the shortest possible time.

StarLine S96BTGSM

– another functional solution to the problem with remote autostart of vehicles. This security and telematics complex was developed in 2022 and is in great demand on the market. It will cost car owners 10,990 rubles. Using this module, launch can be done in the following ways:

1. From a smartphone;
2. BluetoothSmart;
3. GSM interface;
4. Interfaces 2CAN+2LIN.

This kit can be installed quickly and absolutely safely. It should be noted that the module is extremely energy efficient. With this equipment, the driver will be able to monitor the condition of the car remotely using a mobile application. In addition to starting the internal combustion engine, the interface can also be configured for heated seats, auto glass or steering.

Among the autonomous engine autostart modules, it is necessary to highlight Data StartVW (RUB 12,500), which is programmed online. Most often, such kits are installed by owners of Volkswagen, Skoda and Audi. On sale you will find two versions of this kit. The first one comes with a remote control. And the second one has a one-button analogue. Devices communicate with the antenna via a reliable channel. AES-128 encryption is used, which eliminates system hacking and car theft. Such a kit can be installed in conjunction with an alarm system or independently.

When choosing remote engine start units, you need to pay attention to the domestically produced Autostart module. This kit costs only 3990 rubles

It is produced by the company, which has been producing protective systems for vehicles for more than 10 years. In order for the engine to start using such a module, the driver needs to press Lock four times. The kit is easy to use. And it is installed very easily, without the involvement of specialists. You just need to connect the wires correctly.

Conclusion

Modern autostart modules for internal combustion engines help to achieve the optimal operating temperature of the entire vehicle and prepare the interior for the driver and passengers. They differ in their functionality, reliability and durability. In the winter cold, such systems are responsible for warming up the main unit of the vehicle, and in the summer heat they help cool the interior by starting the air conditioners.

However, we should not forget about the increase in energy and fuel costs when installing such units. Excessive fuel consumption is a serious problem for most car owners. Therefore, it is better to make the final decision on installing such equipment taking into account all the positive and negative aspects.

"Samodelkin's" dream

First, let's plug in the eight-pin power connector. For owners of automatic transmissions: you should connect before the automatic transmission circuit breaks. If there is an alarm and it blocks the network after it is connected, you will have to use some kind of service relay.

Next you need to deal with the additional power output. It is designed to power all systems that must start working immediately after starting the engine. So, the car's autostart system in most cases does not need this connection. However, it all depends on the model of the complex you purchased (but this needs to be clarified in the instructions). This is followed by the input to power other power circuits IGN1.

“Fucking basin. "

Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.

Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY! I also advise you to download the application to your phone, it’s much more convenient to work from your phone. Download here.

Car alarm with auto start, how to achieve interaction

Engine starting is designed to disable or bypass certain alarm functions. Therefore, it is very difficult for the autostart system to interact with the car’s security system. If the unit is connected to a security system, most alarm sensors are turned off, after which the ignition is activated. You can purchase an immobilizer bypass unit separately, as it is not expensive.

Those who develop security systems need to create types of security and protection while the engine is running. Often, when the engine is started, protection duties are assigned to the limit switches. One sensor is located on the brake light switch. When an alarm is received, all sensors turn on, doors are locked, etc.

The most common causes of breakdowns

• The shock sensor does not work. Reconfiguring the shock sensor itself may help.
• The alarm goes off too often. There are two probable reasons. Either the settings are set too sensitively, or there is corrosion on the connection ends.
• There is no response from key fob commands. If there is no response from the car to commands sent from the control key fob, the control buttons are stuck or the battery is dead. It may be necessary to completely replace the remote control with a new registration in the system.

The car doors do not close using the remote control.
Technicians at service centers can help you deal with the problem. It is necessary to check and determine where there are breaks in the circuit between the main unit and the door, compliance with the technical requirements of the actuator wires and how the door closing impulse is programmed. Autostart stopped working. Most often the cause lies in faulty wiring. It may be damaged. The immobilizer bypass (most likely the antenna itself) is also installed incorrectly. You should also check the device programming. The car siren does not work. Either the siren itself broke down, or there was a break in the electrical wiring. Complete replacement of the siren itself or rewiring of the entire system will help eliminate the problem. Source

Autostart from phone or application

The modern and most convenient way to activate autostart on a car. Managing remote launch parameters and sending execution commands is available from any place where there is cellular communication and/or the Internet.

Below are the most popular models that are perfect for implementing autorun from your phone:

StarLine S96 BT GSM is a car alarm system with a keyless start system from a smartphone, the ability to authorize using Bluetooth Smart technology and integrated 2CAN+2LIN interfaces. The system has an integrated immobilizer with a Bluetooth tag and a GSM interface for full control of the car from a smartphone at any distance.

The simplest option

Oddly enough, many well-known alarm manufacturers have recently begun to produce additional autonomous modules that work regardless of the presence or brand of the car’s security system, and therefore can be connected at any time. How good is this autostart for a car? Reviews indicate that this is the best option: such systems are easy to connect, you don’t need to be fancy with inserts into the machine’s electronic networks, since the manufacturing company has already done everything for you.

An excellent option is modules from the well-known StarLine in our country. Yes, yes, this company not only has reasonable prices for its equipment, but also offers everyone who wants to integrate an automatic start system into their car. The module can be controlled using two methods at once:

• Smartphone application. Supports Android, iOS, and Windows platforms. Moreover, using the program you can not only start or stop the engine, but also find out the state of charge of the battery, the temperature in the cabin, as well as other useful data.
