Alarm system VAZ 2110 faults

There are two types of immobilizers:

contact;
contactless.

To control the former, keys are used, and for the latter, a special keychain or card is used. As a rule, they are perfectly combined with anti-theft alarms. The first alarms for this brand are called APS-4. They are not particularly reliable, but the successors to the APS-6 are much better. Previously, they were used to control fog lights. It often happens that the APS-6 is located in an old case with the number 4. You should not be afraid of this, the main thing is that the number 6 is indicated on the board.

The basis of the VAZ-2110 immobilizer is the exchange of data between the ECU and the device itself. Either the permission to start the engine or the blocking is triggered, without which the car cannot be started. How to disable the immobilizer on a VAZ 2110 - this question is very relevant for many, especially if the engine has 8 valves.

Immobilizer VAZ-2110: safety requires sacrifices

It doesn't work without sacrifices. VAZ standard immobilizers have been bringing their owners more hassle than benefit for almost 20 years.

Frequent groundless failures , refusals to start, incompatibility with other security systems, unreliability of the elementary base and jambs during assembly force us to disable the standard immobilizer by any means. But first, let’s briefly look at the principle of operation of the device in order to understand how to deal with it.

Principle of operation

The principle of operation of the immobilizer.
The operating principle of any simple immobilizer is ridiculously simple - the device communicates with the engine control unit and gives a certain signal when unauthorized access is attempted . The ECU, in turn, gives or does not give permission to start the engine. It happens like this - to start the engine, it is necessary for the immobilizer to accept the key and only after successful initialization it sends an enabling signal to the ECU. Even in the case when the key fully fits the lock, but is not initialized by the immobilizer, the latter will send a prohibiting signal to the ECU, and the unit will turn off the fuel pump and ignition system. Consequently, starting the engine will be impossible.

Instructions for disabling immo

If you don’t know how to turn off the alarm on a VAZ 2110, then first of all you need to disconnect the plug from the protection. This way you will let the computer know that the immo is physically absent. After disconnecting, you must erase all information about the device from the control unit’s memory. It would seem that everything is simple, but in practice this procedure is not clear to all car owners. So, how to disable the immobilizer on a VAZ 2110?

There are several options - cut the wires or reflash the device, the procedure for cutting the wires is as follows:

First you need to find the system control unit. As we have already reported, in most cases it is installed behind the radio, in the dashboard.
Feel for the connector with your hand and disconnect it from the unit. The connector itself has 20 pins.
Next, you should first count contact number 9 from the plug, then contact 18. Take these wires and cut them with a knife. Next, these two wires must be connected to each other and insulated.
After removing the device, it is necessary to restore the line through which diagnostics are carried out. To do this, you need to install a jumper that will restore communication between the control unit and the diagnostic block. When you cut the wires and then connect them to each other, this is how you restore the K-Line. After all the manipulations, the connector is put in place.

Proper cutting and connection of wires for disconnection

As for flashing the device, for this you will need to prepare a soldering iron with a computer in advance (a laptop will do), as well as a special PAK loader programmer.

Once you have everything in hand, you need to do the following:

Remove and disassemble the control unit.
After disassembly, you need to find the controller plug and connect the PAK loader to it. Having done this, you can consider the standard firmware that was installed during the production of the car.
Similarly, it is necessary to read data through the EEPROM output.
On a laptop or desktop computer, you must save the previously read firmware installed at the factory.
You need to upload a new, clean EEPROM into the control unit via the connector.
Then you can disable the bootloader, assemble the controller and install the device in place.

If your car has a ROM sealed into the control unit, you will need to unsolder it and then perform chip tuning. If you don’t want to do this, then there is a way out - you can use a utility, for example, Combiset, which has the option of clearing EEPROM without the need to resolder the board.

An immobilizer is a vehicle’s protection against theft; if you install an alarm system with auto start, an immobilizer bypass is sold, but experts do not recommend simply picking the brain and removing it from it.

How to disable the alarm on a VAZ 2110 Video

How to disable

alarm system for vaz 2110 video

To find the car where you left it, security alarms will help you solve them.

Security equipment can be classified as follows:

- locks blocking controls and opening the engine hood,

- devices that prevent the engine from starting,

- electrical devices that include an audible alarm,

How does it work

The operating principle of the immobilizer on the VAZ 2110 is based on the exchange of information between the device and the electronic control unit - ECU. Depending on the situation, permission to start the engine or block it is enabled. The ignition circuit and fuel pump are blocked, preventing the engine from starting.

In other words, without using the immobilizer key, you will not be able to drive your VAZ 2110 anywhere. Of course, the immobilizer serves to protect against theft, and not from the car owner himself.

How to disable

We will not delve into the intricacies of the device and circuitry, since to repair, configure and replace immobilizer elements you need to have a good knowledge of microelectronics and experience working with microcircuits.

However, we will briefly look at several options for disabling a full-time security guard. This can come in handy suddenly when the car suddenly stops responding to the working key, and this can happen at any time. History knows of cases when the immobilizer on a VAZ-2110 was completely disabled by a mobile phone call or third-party radio interference.

All ways

To the credit of the developers, it is worth mentioning that the latest version of the decimal immobilizer provides the ability to disable it one-time. This works when such a function is activated in advance. It all looks a little ridiculous , but the engineers couldn’t offer anything better:

When the immobilizer is activated, a six-digit secret code is written into its memory.
The emergency function is activated. (This is described in detail in the instructions for each immobilizer).
Activation occurs by pressing the gas pedal. You need to press the pedal as many times as written in the secret code. That is, if the code consists of the numbers 123456, for example, then you need to press the pedal once, wait a few seconds, then press it twice, wait exactly the same amount, then three times and so on until the last digit. If it doesn’t work out, we train again.

Bypassing the immobilizer when connecting an alarm system

Before you disable the immobilizer on the VAZ 2110, you should study all the methods for such a restart, and the first thing you should start with is this useful option from VAZ. Since it is in these cars that immobilizers most often fail, manufacturers have come up with a simple solution to this problem. Thanks to special software, you can perform an alternative start of the device and make one trip in emergency mode. However, to do this you will first need to enter a six-digit password. It is activated by pressing the gas pedal. This means that if the “reboot” code is “999999” then you need to press the gas the corresponding number of times, at the same interval. This procedure does not cause positive emotions, but in a hopeless situation or when installing an alarm system, this may be the only way to outwit the immobilizer.

Another method is the bypass module (immo crawler). A small electronic device is equipped with transmitting and receiving antennas located inside and outside. The device key or chip is also located inside the case. As soon as you start the car with the alarm, the internal antenna reads the code and transmits it to the ignition switch.

Important! If the car is started with the key, such a crawler will not work.

If one of the keys is lost, the remaining spare can be disassembled and the chip removed from it and secured to the ignition switch. After this, you can use any ignition key and the immo will be disabled.

This concerns generally accepted tricks that will help in solving such issues as disabling the immobilizer on a VAZ 2114. If you want to manually disable the immo, then you must adhere to the following recommendations.

Possible problems with the immobilizer on the VAZ-2114

The standard anti-theft device on the VAZ-2114, according to user reviews, can from time to time block the engine so that even the owner of a working key will not be able to start it. This is due to the peculiarities of the functioning of this device - it draws conclusions about its own actions based on the code of the working key of the owner of the car, and gives commands to start the engine. The driver's problems with an immobilizer begin when the system stops accepting the code. In these cases, the electrical control unit will shut down the engine and it will not start. You can influence the standard anti-theft system by connecting a diagnostic device or an ordinary computer.

Experts note a number of cases where the immobilizer system malfunctioned when the mobile phone was turned on, which created interference.

Tips for installing crawler

To give the Tens engine the ability to autostart, you can install a crawler. The problem is that the code reader in VAZ-2110 cars is not standard. This leads to the following conclusion:

The purchased crawler is included in the reader loop gap. Any other option is excluded.
You can make an additional antenna yourself. It must correspond to the antenna that is installed in the VAZ reader (410 µH, 25 Ohm).

Let's look at how to connect a crawler purchased in a store:

Inclusion of a trouser loop in a gap

The black wire shown in the diagram goes to the alarm control output.

Usually they purchase a device that is not compatible with the inclusion of a standard loop in the gap. Comments are unnecessary here. Mistakes are also made during installation: in the BP-5 lineman they use the XS4 terminal block instead of the XS3, etc.

How to turn off the car alarm with your own hands without a key fob

Greetings, dear friends! We have a rather interesting topic under consideration, since we will talk about how to turn off the alarm in a car when the key fob does not respond to our commands.

Almost every driver's car has a security system. And it doesn’t matter whether the car was bought for cash, through the Trade In system or with a mortgage loan.

Some people use expensive solutions, others buy more budget tweeters. But let's be honest with ourselves. Even a simple alarm greatly reassures the car owner, since he knows that the car is protected. Therefore, you can find warning lights on a VAZ 2107 or VAZ 2110 just as often as on medium-sized and expensive foreign cars.

But sometimes it happens that the alarm starts screaming, and the commands from the key fob have no effect on it. For example, you stopped at a self-service car wash, and the car suddenly screamed furiously. And here it becomes necessary to disable the security system with your own hands. Today we’ll talk about how to do this.

In what cases is it necessary to disable the immobilizer?

There are a number of cases when there is a need to turn off this device:

If it is defective from the factory and because of this the machine does not work properly. As a rule, this occurs on the very first car models.
If the computer battery is completely discharged and prevents the engine from starting.
If the ECU has blocked it.
It also happens that the system is worn out and requires replacement.

As we can see, there are different reasons for disabling the immobilizer. It should be understood that this procedure is very serious and quite complex. You need to know all the subtleties.

Simply unplugging the connector can completely shut down the entire engine starting system.

Disabling without key fob

To turn off the sound of a blaring alarm, but do it without a remote control, the driver will need to find a way to get inside the car. It’s good if there is central locking and the remote control works fine.

On some cars, thanks to the alarm, the engine does not start. That is, it is unlikely that you will be able to leave the scene and head to the service center on your own. We need to look for alternative ideas. Now, when the car is quietly standing in the yard, you can watch the visual videos and study the features of turning off the alarm without a remote control if it suddenly breaks down. But it is better to have certain knowledge and skills in advance. To do this, you at least need to study the operating manual for your particular alarm.

There are a huge number of security systems. Take the same security system from Starline as an example. And their range is regularly expanding. This is good and bad at the same time. But that’s not about that now.

This is the situation. The alarm works and annoys everyone around you, including you. The key fob does not respond to any pressing. What to do?

There are several basic ways to disable the security system remotely. Let's take a closer look at them. Step by step it looks like this:

Transfer to maintenance mode. For this purpose, many systems have a special secret button, the location of which only the driver should know;
Translation algorithm. Each system has its own. Usually it is written in the operating manual of the alarm system itself, or of the car, if the security system comes from the factory;
Most often, the algorithm is based on sequentially turning on and off the ignition in parallel with pressing a secret button;
Pin. There are systems where the protection is even more complex. Then you need to use a special code that the driver must know and remember. Some manufacturers send a code as an SMS message to the client’s phone;
I can’t find the button, I don’t remember the PIN code. Sometimes it happens. Here you will have to open the hood and completely turn off the power supply. Try to disconnect the wires from the bell, that is, the source of the sound of your security system;
If this does not work, try removing the fuse. It is usually located near the alarm unit. On some cars there is no fuse, but a relay. It is more difficult to dismantle.

General information

The installation of VAZ immobilizers was put on stream after the manufacturer started producing injection engines. The purpose of the immo is to block the start of the power unit in the event of unauthorized entry into the car. Before installing or disconnecting the device in your car, we suggest that you familiarize yourself in more detail with the varieties, as well as the principle of operation of the system.

Kinds

Today, cars are equipped with either contact or contactless immobilizers, with the latter being more in demand among consumers. Contact systems are controlled using a key, while contactless systems use a remote control or card. If you don’t know how to connect the alarm to the central locking, then this is quite possible. Installing an alarm system on a VAZ 2110 with your own hands is quite possible with a further combination of the alarm system and immo (the author of the video is the IZO channel))) LENTA).

As for the “dozens,” this type of alarm is found only on injection versions. To control the device there is a set of keys. Red represents the master key, which is used to activate the protection. The black key is used by the owner of the car. The procedure for “learning” or activating the system is usually carried out in the showroom, before the car goes on sale. Although, in principle, connecting the alarm to the central locking of a VAZ with further activation can be done at home.

The first “tens” were equipped with APS-4 systems, but after some time the cars began to be equipped with more modernized versions of APS-6. As for installation, the immobilizer is located either in the steering column, or behind the dashboard, or behind the radio, and the code is in the ignition switch. The APS-6 system does not connect to the VAZ hazard alarm, but can be used to control power windows (if they are electric), as well as fog lights. It should be noted that some APS-6 are equipped with a body from the fourth models, this is probably due to the oversupply of APS-4 production. In this case, the number 4 will be marked on the case, and the diagram itself should have the inscription APS-6.

Principle of operation

Immo connection and operation diagram

If you decide to connect the immo to the central locking of a VAZ 2110, first familiarize yourself with the principle of operation of the system. The operating principle of the immo is based on the exchange of data between the device itself, as well as the control unit. Taking into account a particular situation, the immobilizer determines whether to give permission to start the engine or block it. In the latter case, the ignition circuit and the fuel pump are blocked, making it impossible to start the engine. In other words, if you do not have an immo key, then operating the car will be impossible.

2. ROM on the immo chip

Kinds

Today you can find contact and contactless immobilizers, the latter of which are more in demand. The first ones are controlled using a key, and for the second ones a key fob or card is provided. They are combined with other anti-theft systems.

Key master

On the VAZ 2110, the immobilizer is found only on models with injection engines. When leaving the production line, the car's protective functions are not activated. A special set of keys is provided for this. One of them is red. This is the master key that activates the protection. The other two, which are black, are used by the car owner.

“Training”, that is, activation, is usually performed at a car dealership before preparing the car for sale. Although some clients are easily able to perform the procedure on their own.

The VAZ 2110 was the first to be equipped with APS-4 systems, but after some time improved APS-6 models appeared. The reading part is installed in the steering column, and the code is installed in the ignition key. APS-6 additionally serves to control fog lights and electric windows.

APS-6 module board

Sometimes an updated immobilizer comes in an old housing, which, apparently, was in abundance at production. If this is so, then there is a number 4 on the case, and the inscription APS 6 is printed on the board. Microcircuits may differ from each other due to different periods of their production.

Why do you have to disable the immobilizer?

VAZ began to equip immo only with injection-type cars. The first anti-theft devices of this series appeared on the VAZ 2110 and they were called APS-4. Today, more modern APS-6 models are more common. Now all cars of the 2110 to 2115 series are equipped with this particular device.

The most common problem with this device is the loss of the key or if the car owner, without knowing it, erased its code. Speaking specifically about VAZ standard immos, you can more often encounter a problem related to the fact that the lights in the cabin do not go out and, as a result, the alarm does not go off. In addition, malfunctions of the immobilizer software often occur, as a result of which its central unit does not read information about the key or considers it “not native”. As a result, when you stop to refuel, you risk being left in a stalled car.

To reprogram (marry, bypass, flash, upgrade, adapt) a device, you must first turn it off. In addition, immobilizers are usually disabled when installing a car alarm.
