Where is the VAZ 2114 immobilizer located?

All VAZ cars with an injection power system, regardless of the owner’s wishes, were and are equipped with a standard anti-theft system. Evil tongues say that the system has a slightly different purpose, however, we, as owners, are interested in it primarily as a protective system for the VAZ-2114. How to disable the immobilizer, what will happen to the engine after this, is it possible to live without a standard anti-theft system - a little about everything right after the description of the principle of operation of the device.

Why is an immobilizer needed and when is it not needed on a VAZ-2114?

The standard immobilizer is designed to deactivate the car engine in the event of unauthorized entry. Simpler - a thief can break the door lock, break the ignition switch, or even start the engine. But not for long. The system will shut off fuel and cut off power to the engine as soon as the engine has been running for a few seconds, if it starts at all.

Immobilizer VAZ-2114

The standard immobilizer recognizes the owner using a key with a specific digital code, which is supposed to be quite difficult to fake. Moreover, in more modern cars, the immobilizer can even allow the thief to move away, but the signal about the break-in and theft has already been sent where it should be.

The latter does not apply to the VAZ-2114. There, the immobilizer is only responsible for blocking the engine and nothing else. However, the device itself is not highly reliable and can shut down completely at any moment, preventing the owner from starting the engine.

This was a problem with the factory anti-theft systems of the first releases, and continues to do so now.
It may also be necessary to get rid of a full-time security guard in cases where there is a need for a more advanced alarm system, more reliable and more complex, say, with auto-start. In these cases, you have to turn off the device or look for workarounds.
Operating principle of the immobilizer
The principle of operation of the standard anti-theft system on the VAZ-2114 is simple, like everything ingenious.
The immobilizer can only work with an electronically controlled engine. Therefore, other anti-theft systems are used on carburetor engines.
So, the immobilizer simply exchanges data with the electronic engine control unit and, if necessary, prohibits it from sending impulses to certain systems.
Immobilizer chip in key
The device makes conclusions based on the code that the owner’s chipped key carries. As soon as the key is in the immobilizer's receiving area, the chip sends an encrypted code to the device, the immobilizer accepts it and gives the go-ahead to the ECU to start the engine.
If the code is not accepted due to certain circumstances, you can fiddle with the ignition switch as much as you like, the engine will not start, the electronic control unit permanently blocks the engine.
Immobilizer problems
The whole problem is that the immobilizer in the VAZ-2114 communicates with the ECU via the diagnostic port. This means that you can influence the operation of the security system with the most innocent diagnostic attempts, simply by connecting a diagnostic device or computer. In addition, there are often cases when the immobilizer was blocked by itself simply due to interference from a mobile phone. In short, it is often necessary to completely disable the device, and sometimes in an emergency, when there is simply no other way out (except for completely replacing the electronics).

How to bypass the immobilizer on a VAZ?

How can you disable the immobilizer on the Lada Priora?

If the problem is not brought to a critical state, and the car is still running, you can resort to a number of tricks.

Immobilizer connector

Domestic motorists cope with critical situations as follows:

If you are a prudent driver, install an alternative immo – this is a special module for bypassing the immobilizer in a critical situation. These are two small transceiver devices connected in parallel with a protective device to the computer and ignition system. If the car is blocked by a standard system, you will have a mechanism at hand that can start the vehicle, contrary to the established prohibitions. The only negative is that you will have to fork out extra money for electric ignition.
If you have lost a key and are afraid of losing the second one, take the remaining one apart. The main thing is to carefully remove the chip and not damage it, after which it can be placed on glue near the ignition. A significant disadvantage of the solution is that the car will start with any key.

If the above options do not suit you, then you will have to approach the problem with full responsibility and disable immobilizer 2114 manually.

Disabling the immobilizer on the VAZ-2114

Not every motorist has deep knowledge in the field of radio electronics, which is what numerous services take advantage of and sell new electronics for crazy money.

It is much easier to completely disable the device, and you don’t even need to know circuit design to do this.

It is enough to know that in order to disable the device and further normal operation of the engine, it is necessary to completely erase information about the immobilizer in the memory of the electronic control unit. Theoretically, that's all. Now let's move on to practice.

To disable the immobilizer on a VAZ-2114 you must:

Despite the simplicity of this method, it does not guarantee correct disabling of the immobilizer.

Flashing the ECU

If you are unable to disable the device, you will need to reflash the computer, which we do not recommend doing on your own. However, if there is simply no other way out, we will try to reflash the VAZ-2114 ECU with our own hands.

Let us remind you that our task is to erase information about the immobilizer from the ECU memory.

To remove the immobilizer in a more complex way, we will need special software, a PC, a soldering station (soldering gun), and a programmer for microcircuits. And everything is done like this:

We remove the ECU from the car.
Dismantling the electronic control unit
Open the lid.
We find a microcircuit with registered data about the immobilizer.
On the January 7.X ECU this chip is designated 24C04, this is the ECU EEPROM memory. ECU controller EEPROM 24С04
There are two options - find a new chip in advance, or clean the old one. To clear the memory, you will need to use a Windows computer and a program to reset the chip's memory.
We unsolder the 24C04 microcircuit and replace it with a new one. Or we reflash it.
Flashing (erasing immobilizer data and writing a clean chip) on a PC using a programmer takes several minutes. After that you can solder it in place.

Before installing the ECU and before connecting it, you must physically disable the immobilizer. Otherwise, the flash memory reads the data about it again and you will have to do everything all over again.

Of course, these are not the only ways to remove an immobilizer, but they are the most accessible and effective. Good luck to everyone!

Location of the immobilizer on the VAZ-2114

Location of the APS-4 immobilizer on the car

The fact is that the Tolyatti designers who created the “four” mocked the consumer by installing an ECU and an immobilizer under the pipes of the car’s heater system . Thus, if the tightness of the system is broken, they must be filled with antifreeze.

What is an immobilizer and why is it criticized?

Since the beginning of the 2000s, an automobile anti-theft system (APS) has been installed on all injection engines produced in Tolyatti.

Initially, the first “tens” were equipped with APS-4 , but they were soon replaced by more modern APS-6 .

The standard anti-theft system is otherwise called an immobilizer.

The meaning of the system is as follows: an attempt to steal a car will end in nothing. The attacker will not be able to start the engine, and if he does start it, then after driving a few hundred meters the fuel supply will stop and the engine will stall.

The idea is good, but there are a number of problems that arise during its operation:

Software failure . The electronics does not see the update of information supplied by the ignition key or does not recognize it. There were cases when, having stopped and turned off the engine, it was no longer possible to start it.
Engine blocking due to low battery . Leaving your car in a parking lot for several days in winter can accidentally activate the system.
Serious problems when connecting an alarm system with auto start.
Breakdown, contact closure due to poor location .

Interesting! The first injection VAZ-2114 were produced either without APS, or with an unconnected unit dangling inside on its own wiring. Nobody knows what this was due to (savings, lack of equipment or another reason), but the fact remains.

Troubleshooting

In the case when a car with an active immobilizer does not communicate with the computer, you need to know the following: the K-Line wire connects the diagnostic connector and the APS. Only then does the power enter the electronic control unit.

In the event of a malfunction, you need to make sure that the system is connected to the correct connector. If the result is positive, you can try to disconnect it and bridge the 9th and 18th contacts .

This will result in a direct connection between the ECU and the diagnostic connector, bypassing the anti-theft system.

In case of malfunctions related to the operation of the immobilizer, it is necessary to take into account the fact that this is a complex electronic device. Therefore, to troubleshoot it, it is recommended to contact a professional auto electrician.

Important! In the event of breakdowns associated with its operation, you need to know that restoring functioning after the intervention of unskilled hands can be difficult, and in some cases completely impossible.

Deactivation and activation (pros and cons)

The Bosch ECU on the VAZ-2114 came complete with an APS-4 immoblizer

When deciding whether to deactivate the immobilizer or not, you need to know the following. APS-6 or 4, although it has a number of significant drawbacks, it really counteracts hooligans who may decide to ride in a car parked near the entrance. The alarm does not turn off the engine and fuel system.

The anti-theft system of the 6th series, on the contrary, turns off the power to the fuel injectors (the 4th turns off the fuel pump and glow plugs). Therefore, it’s up to you to decide whether to connect it after the next glitch or not. But at least, if they decide to steal a car, then they will need their own ECU; you can’t take the car with your bare hands.

We are looking for the “culprit” of all problems

Let's assume that we are talking only about the VAZ-2114 hatchback. If the key, that is, the key fob, needs to be leaned against the platform, disconnect its two connectors (the light bulb and the antenna). And then, taking a screwdriver, you can dismantle the separate block attached to the right of the steering column:

Dismantling the APS module

The unit itself is called APS-4, but in its case, if we talk about the last years of production, APS-6 electronics may be located.

Let's say they are installing an alarm system with auto start, and a standard immobilizer, such as APS-6, has been activated. There are four solutions:

An immobilizer bypass is connected to the alarm, and a chip key is placed inside the bypass body;
A good option is to install keyless crawlers, only cars of the 2114 family do not have a CAN bus, and there is nowhere to connect digitally;
You can also switch the immobilizer to service mode, but in APS-6 modules, unlike APS-4, this feature is blocked;
Finally, you can get rid of the standard protection completely, but to do this you will need to reset the EEPROM of the ECU.

In general, EEPROM is a “storage device”, and the ECU is the engine controller. It turns out that you will have to work with the controller unit, but the immobilizer itself will remain the same.

Expert recommendations for activating and deactivating the immobilizer on the VAZ 2114

The VAZ 2114 immobilizer is an anti-theft device designed to protect the car from theft. If the car is broken into and when you try to start the engine, the immo will activate the engine blocking to prevent movement in the car. For what reasons the immobilizer may fail and how to disable it yourself, we will tell you in this article.

Manipulations with the ECU controller

The VAZ-2114 controller unit may belong to the following family - January 5.1.X or ITELMA 5.1. The digital designation printed on the label in this case looks like this: 2111-1411020-71 (the numbers “72” may appear). If the last two digits are a “space” or the number “70,” it means that the BOSCH M1.5.4 controller is installed. In the latter case, erasing the EEPROM involves disassembling the block, but without soldering. And in the first case, you don’t even have to open the block cover.

Resetting EEPROM in a BOSCH controller

Let's see what the controller board looks like from below:

ECU BOSCH M1.5

The 24C02 chip is the EEPROM memory. Circle the 5th and 6th taps, B and C, with a marker. These points are intended for connecting the programmer, which is assembled from three transistors.

The programmer circuit in question looks trivial. This means you can quickly assemble it with your own hands:

Programmer for EEPROM 24C02

The device is connected to the COM port of the computer. And the voltage “12 Volts” is taken from the MOLEX connector. Of course, ground must also be taken from this connector. The maximum current consumed by the ECU will in any case not exceed 0.5 A.

Now let’s look at the procedure for allowing the ECU to “forget” about the existence of the immobilizer:

The 18th and 27th contacts of the block are supplied with supply voltage (12 Volts);
The common wire, that is, ground, is connected to pin 19;
Wait 10 seconds;
Connect contact B of the programmer to tap 5;
Connect contact C of the programmer to tap 6;
In the Combiset program interface, select the “Clear EEPROM” item, press the “Install” button;
They wait a few minutes.

The wiring of the main ECU connector looks like this:

ECU block, 55 pins

The Combiset application must be downloaded from the official website (almisoft.ru). Even the Demo version, available in the Download section, is suitable.

In the program itself, you must correctly set the number of the COM port that will be used. The COM-1 port is shown below, but this is not the only option.

Combiset program interface

How “January” controllers are “untied”

A common type of controller in VAZ-2114 cars are the following blocks: January 5.1.X and ITELMA 5.1. They need to be programmed the same way. You need to use an adapter from the COM port to K-Line, but you can easily make it yourself:

Screenshot of the Flashecu program window

The erasing procedure takes several minutes.

The block itself, which was mentioned above and which needs to be “untied” from the immobilizer, is always located in one place - under the tunnel cover on the right:

Interior of the fourteenth model

Of course, we are talking about the 2114 family, and in other VAZ cars the unit will be more difficult to find. Installation and disconnection can be done as follows:

Remove the negative terminal from the battery;
Unscrew the fixing bolt and remove the clamp together with the block;
Disconnect the connector.

During installation, the steps are carried out in reverse order. But there is one trick.

After connecting the ECU, power is supplied to the network. And then, oddly enough, you need to turn on the ignition and wait for the Check lamp to come on. And only then, turning off the ignition, can you continue operation.

Note that the immobilizer itself, after flashing the unit, should not even come into contact with the latter. Therefore, having disconnected its terminal block from the immobilizer, they carry out the standard modification:

The wires are cut off from terminals 9 and 18;
The resulting branches coming from the loop side are connected.

You don’t have to change anything, but simply disconnect the connector completely, losing some features:

Polite lighting;
PTF rear headlight control;
Window control.

As you can see, the immobilizer in modern VAZ cars has many functions. And they turn it off for one purpose - to activate the alarm system with auto start.

The immobilizer bypass module in any VAZ car works well in one case - when it is connected to a break in the antenna circuit. But not all factory-produced modules are designed for this connection option in principle.

Getting rid of the immobilizer in Lada-2114

Having connected a new alarm system, they often encounter one problem - the autostart does not work. You need to immediately check whether all connection points are used. In the latest VAZ models, such as 2114, the ignition switch contains three terminals: starter, power, ignition. It’s difficult to get confused here, but the engine can start and stop after 5 seconds. In reality, this is how standard protection works. How to deal with it is discussed further.

The unit itself is called APS-4, but in its case, if we talk about the last years of production, APS-6 electronics may be located.

Safety Notes

A standard device such as the APS provides the best level of protection. But an alarm system, even the most modern one, can be considered only an additional security device. It does not exchange data with the ECU and does not prevent the engine from starting. At the same time, when installing an alarm system with auto-start, blocking is always implemented. Two cords going to the main unit are connected to the starter cable. And until the security is turned off, you cannot start the engine.

Typical signaling connection diagram

All wiring connected to the ignition switch carries significant current. But doing the installation yourself does not always ensure good quality connections. In general, it is better to entrust the autostart connection to an experienced electrician. We wish you success.

Polite lighting and door switches

Any alarm or security system is always equipped with an input connected to the door limit switches. In VAZ cars, the control wire can be connected to one point (A). Diodes are not used in this case:

Door control connection diagram

Be sure to carry out the setup: the delay in polling the limit switches should be 20-30 seconds. If this is not done, false alarms will occur when the security system is turned on. The reason is the operation of the APS unit, which does not turn off the light after the driver's door is closed. The option in question is called “polite backlighting.”

There are even modern alarm systems that do not allow delaying sensor polling. Installing diodes will help solve the problem.

In theory, pins 7 and 13 of the BSK are the connection points that need to be decoupled by two diodes. But as practice shows, it is better to implement a circuit with three additional diodes (see figure). The alarm is connected to point B, and setting the polling delay in this case is not required. Good luck.

Main problems and features of immobilizers

Immo can only interact with the ECU, so this anti-theft device is not used in carburetor cars. Immo exchanges information with the control module and, if necessary, prohibits the device from sending signals to certain nodes. This device makes the appropriate conclusions based on the code that is located in the master key chip. When the key falls within the range of the immo, the chip transmits an encrypted signal to the device, which processes it and gives instructions regarding starting the engine or prohibiting it.

What malfunctions are typical for the system:

Since the anti-theft device interacts with the control unit via a diagnostic line, its operation may be impaired as a result of incorrect diagnosis.
Various interference that even a mobile gadget can produce. Interference is usually caused by more powerful equipment and stations, but even a smartphone can be the cause.
A manufacturing defect, due to which the device’s circuitry has “glitched” and can no longer function. As practice has shown, defective systems were often found in the first cars that were equipped with immobilizers and injection engines. In this case, the cause of the malfunction is solved either by repairing or replacing the device.
Also, immo, like the alarm system, may stop working due to a dead car battery. This problem often manifests itself especially in winter, when batteries are more susceptible to discharge as a result of exposure of the electrolyte to low temperatures. In particular, this is true for old batteries that have already reached the end of their service life. In such cases, car owners are required to know how or immo.
Another reason why the immo may stop functioning is a software error. Problems of this kind can be solved by qualified diagnosticians, because there is a possibility that you will have to reflash the control unit (the author of the video about the malfunction of the anti-theft system is the IZO channel))) LENTA).

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.

how to disable the immobilizer.

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

Disconnection Guide

Do I need to turn off the immo or alarm and how to do it correctly? We invite you to take a closer look at these issues.

Is it necessary to disable the immobilizer on the fourteenth VAZ model?

If there is a need, then of course it is necessary. The need to turn off the alarm or immobilizer arises in cases where the system blocks engine operation and starting the power unit becomes impossible.

How to disable?

If we are talking about signaling, then first of all you need to know about the connection points that were used during installation. Every anti-theft system has an emergency stop button, usually called the Valet service button. It doesn’t matter whether it’s a European emergency warning button for a VAZ 2114, a new model or an old one.

The combination with the use of Euro emergency lights in the event of the anti-theft system being disabled is described in the operating manual. This process is individual for each individual signaling model, so we will not describe it. If it’s not on “four”, then you’ll have to turn off the central unit, but you can’t do without the help of a professional in this matter.

As for how to properly disable immo with your own hands, the procedure is as follows:

First you need to find the block of the installed anti-theft system. If you installed the immobilizer yourself, you should know where the control module is located. If the installation is installed from the factory, then the module should be located inside the dashboard, directly under the steering wheel.
Next, you need to disconnect the connector with the signal wires from the control module. Disconnect the wires and move them aside.
Now you will need to find pins numbered 9 and 18, for a total of 20 pins on the connector.
Contacts numbered 9 and 18 must be cut using a utility knife. Strip the contacts of the cut wires, then twist them as securely as possible and insulate them. Use electrical tape to insulate the section. By completing these steps, you can restore the K-Line diagnostic line, which will allow you to monitor the condition of the main systems and components of the vehicle.
Next, reinstall the connector. This way you can disable the anti-theft system and start the engine. This method is the simplest, but it must be borne in mind that it does not guarantee the correct disabling of the anti-theft system.

3. Screenshot of the flashing utility

A more complex, but more effective option is to reflash the control unit. To implement it, you will need a soldering iron, a computer with a flashing utility, and a board programmer.

Flashing is carried out as follows:

First, the control module is removed from the car.
Next, the cover of the device is opened.
Now you need to find a board with immo data written on it. If your car uses the January control unit version 7.x, then the circuit designation is 24С04.
Next, you have two options for solving the problem - you either install a new circuit, or you will clean the old one. To perform the cleaning, you will need a computer or laptop with a Windows operating system, as well as an appropriate memory cleaning utility. There are many programs on the Internet, you can select software for a specific ECU model.
The next step will be to desolder the circuit using a soldering iron, as well as install a new board. Well, or you reflash the circuit, whatever. If we are talking about firmware, then with the help of a properly configured utility you can complete this task in just a few minutes.
When the process is completed, all you have to do is solder back the new board and check the functionality of the system.

Almost all new cars are equipped with immobilizers. These electronic devices make it possible to prevent the theft of a vehicle by disabling the “vital” systems of the car. As soon as the attacker gets into the car, he will try to start the engine and drive away. The immobilizer will either not allow this to be done at all, or the thief will be able to drive away several hundred meters, after which the fuel supply will stop and the engine will stall.

Such immobilizers can be contact or non-contact. The former have already ceased to be produced, while the latter are very popular among car owners. However, sometimes situations arise when a car enthusiast wonders how to disable the immobilizer on a VAZ 2112 or another brand. The fact is that in the brainchild of the domestic automobile industry, problems related to electronics and various devices often occur. Let's look at the main reasons for disabling the immobilizer.

How to disable the VAZ-2114 immobilizer

Disabling the immobilizer on a VAZ-2114 is possible in cases where:

there is a factory defect in the anti-theft device;
interruptions in operation occur after the battery is discharged;
the anti-theft device has been replaced with a newer version;
There was a failure to start the internal combustion engine.

There are several ways to disable the anti-theft device on a VAZ-2114 with your own hands:

Disconnect the device connector or install a jumper to diagnose the device.
Seek help from the installers of the service company by arriving there by car, or deliver there only the dismantled anti-theft system unit.
Disable the immobilizer yourself.

To do this, perform the following operations:

Find the location of the control unit.
Disconnect the connector from the ECU.
The wires are cut off (pins 9 and 18) and connected to each other, the connections are insulated.
Place the device in place, connecting it to the computer.

This method makes it possible to block anti-theft signals sent to the ECU. It is simple, but you need to disconnect the main elements correctly, cut the wires to a length that allows the connection to be made, and insulate them correctly. Thus, this method allows you to bypass the immobilizer.

The last method is to reflash the device, which is recommended to be carried out by a specialist in a repair facility. But this procedure can be performed independently. For this you will need:

special computer program;
laptop or personal computer;
soldering iron and microcircuit programmer.

The device is reflashed by performing the following operations sequentially:

Remove the internal combustion engine computer and open the cover.
Remove the microcircuit responsible for the operation of the device.
The memory of the removed microcircuit is reset using a special computer program or the old microcircuit is replaced with a new one.
Disconnect the system from the vehicle’s on-board network so that the ECU memory does not record information.
The reflashed ECU is installed on the vehicle.

Once the immobilizer flashing is completed, reprogramming is performed using the key. Since the flashing process is not easy, experts recommend doing this work in a service center to ensure that the device is restored to operation.

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.

Why is it needed and when is it not needed?

The standard immobilizer for the VAZ 2114 leaves the assembly line untrained. There is no data about master keys in its memory. Therefore, the complete delivery set of the car contains 3 keys: red (training) and two black (working). The owner will have to learn the system, with which the salon employees or the previous owner will help him when selling the car second-hand.

In domestic cars, the immobilizer communicates directly with the car's ECU, which locks or unlocks the system. This is the biggest disease of the entire system, because domestic automatic systems leave much to be desired. Communication between the immobilizer and the ECU can interfere with the connection of diagnostic equipment, signal interference, and even normal interference from a mobile phone.

Another weak point of the device is the battery. If it goes down completely, the K-Line (communication line with the ECU) will be disrupted and the same consequences will occur as with unauthorized access. Regardless of the reasons for decoding the connection between devices, you cannot avoid a trip to the service center on a tow truck.

INTERESTING! Until the latest series of VAZ cars, domestically produced immobilizers were the favorite way to make money for service stations. They solved the problem in the most profitable (for themselves) way - by completely replacing the ECU.

There were so many unreasonable system failures (especially in cars before 2001) that VAZ designers developed separate software for emergency starting of the car. A machine controller configured in advance for this function will allow a single start followed by a safe trip.

The device does not have external controllers, and therefore the password is entered by pressing the gas pedal. A special algorithm must be followed, which turns this function into a perversion. You can read more about the setting algorithms in the instructions for the immobilizer.

Having assessed the above-described system errors, the VAZ design bureau in 2004 replaced the brand of the serial device with APS-6 (previously APS-4 was installed). They developed new software.

Immobilizer software interface

The most noticeable innovations were: a code key, which moved from the gas pedal to the steering column and door controls (including power windows).

Although the new functionality has become noticeably better than the previous one, failures and “miracle masters” still force car owners of the fourteenth to change the ECU. Sometimes the owner can unintentionally delete the code on his own, after which the question of expensive car repairs will arise. Also, do not forget about some of the tricks that domestic car enthusiasts go to in order to deceive the cunning system.

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.

How to disable the immobilizer on a VAZ-2114 with your own hands

The manufacturer equips basic VAZ-2114 cars with an injector with an anti-theft system such as an immobilizer. But for various reasons, some owners of this vehicle model complain that it is impossible to start the engine (ICE) due to a malfunction of the immobilizer. Solving this problem and disabling the immobilizer on the VAZ-2114 is a task that many car enthusiasts are trying to solve on their own.

Rules for disabling the immobilizer

Before disabling the immobilizer, you must disconnect the connector from the protection, that is, give the system a signal that the immobilizer is missing. After this, you can erase the data on the device and replace it with new ones. But in practice everything is not so simple.

If you turn off the device incorrectly, the system may perceive this as unauthorized access and the car will be completely blocked. In this situation, it will be difficult to do anything, all that remains is to call a tow truck. Therefore, be extremely careful. There are two schemes for disabling the immobilizer.

Cut the wires.

To do this, find the immobilizer control unit. Most often it is located behind the center console, next to the radio. After this, you need to find the connector on the block and remove it. In this connector you will find 20 contacts, first find the ninth and then the eighteenth. These two wires need to be cut, connected and insulated.

After this, all that remains is to remove the immobilizer and restore the line used for diagnostics (K-line). To do this, install a jumper that will restore communication between the ECU and the diagnostic block. We cut the wires and connect them, after which the connector is placed in its rightful place.

Reflash it yourself.

For this you will need:

PC or tablet;
soldering iron;
PAK-loader programmer.

Next, you need to disassemble the ECU, find the controller connector and connect the PAK loader to it. We read the factory firmware with the BIN extension. It is also necessary to read information through the EEPROM connector. After this, you need to save the factory firmware on the computer and upload a clean EEPROM to the ECU. After this, you can disconnect the bootloader, assemble the controller and install it in place.

A soldering iron will be required if the auto ROM unit will be sealed. Or you can use the COMBISET program with the EEPROM cleaning function, then you won’t have to unsolder anything.

If we are talking about a specific APS-6 immobilizer, then it will be useful to know the purpose of the immo outputs.

The green wire belongs to the antenna coil in the ignition switch.
Blue is responsible for the additional power relay (for power windows).
Green-white comes from the headlight switch.
Orange and white refers to the rear fog lights.
Pink is a constant plus from the battery.
The yellow wire connects to ground when the rear fog lights are turned on.
Yellow-black refers to K-line, if it is CL 7, then we have a wire from the diagnostic block, and if CL 8, then from the EUR control unit.
The white one goes to the antenna coil located in the ignition switch.
The green-black one comes from the driver's side door VC.
Brown - from VK dimensions.
Black is mass.
Orange refers to terminal 15 of the ignition switch.
