Where is the Immobilizer VAZ 2112 located?

VAZ-2112 cars were equipped with 8 and 16 valve injection engines, which in turn were equipped with their own protection system - the so-called immobilizer. Using this device, any attempt to start the engine without a special key was blocked. In case of problems with the immobilizer, starting the engine was not possible even with a set of original keys and tags, what should I do in this case? Just disable the immobilizer!

The video shows how to disable the immobilizer on VAZ cars:

Types of immobilizers for VAZ-2112 (APS-4, APS-6)

Installed immobilizers can be contactless and contact , the former are, of course, the most popular on the modern market, since a special key fob card was invented for their interaction, and in the case of contact ones, a special key is provided for control. In any case, such a protection system is combined with the car alarm that is most familiar to us.

Two types of immobilizers were installed on the VAZ-2112: APS-4, and after APS-6.

The advantage of the more recent model is its active interaction with power windows and fog lights.

The principle of operation of the immobilizer

The principle of operation of the immobilizer on the VAZ-2112 is the exchange of information between the ECU and the device itself. When these devices interact, the system is allowed to start the engine, or it is blocked by closing the fuel supply circuit and the fuel pump.

Accordingly, when the fuel line is closed, the car will not go anywhere and will not even move.

When is shutdown necessary?

There are several reasons why you need to disable the immobilizer:

1. Disabling is necessary when errors occur in the immobilizer that prevent the engine from starting. It happens that this is due to defective goods supplied from the manufacturer's factory. Without disabling this anti-theft device and having faults in it, you will not be able to start the engine.
2. When your battery is completely discharged (for example, in the cold season - approx.), the immobilizer may take this as an error and prevent the engine from starting. This happens because the anti-theft system, exchanging information via the diagnostic line, loses contact and perceives this as an attempt to steal.
3. The third reason why it will be necessary to disable IMMO is because it is blocked . It can occur due to a broken code when connecting diagnostic equipment to the system with the ignition on.
4. And the fourth reason, the most banal one, is that the anti-theft device may simply break.

As you can see for yourself, there are quite a few reasons why the immobilizer can fail, but you cannot simply disconnect the power connector from it, because this will result in a complete blocking of the engine and all its systems.

When performing such an operation, it is important to follow a certain sequence and order of actions.

How to extend the life of a generator

We figured out a little about the question of which generator is better to install on the VAZ-2110 by listening to the opinions of experts. Now is the time to talk about how to extend the life of a current generator without repairing or replacing components. You will definitely find these tips useful:

• carefully avoid puddles, and if it is impossible to avoid them, then cross the water at minimum speed. This must be done because water getting on the hot winding will lead to cracking of the varnish insulation. The next puddle, overcome at high speed, will already lead to a short circuit of the winding;
• Washing the engine can also lead to a similar problem. You need to carefully pack the generator in plastic in advance. Require drying of the engine with compressed air; after this procedure, try not to immediately load the generator, including all consumers. And don't accelerate too hard for a while to avoid sudden temperature changes;
• Never help start a stalled car using your battery without turning off your engine. Double load can literally kill your generator;
• do not unnecessarily connect all consumers of the on-board network, this will create an excessive load on the generator, especially if the generator is standard;
• check the tension level of the alternator belt more often and tighten it if necessary;
• Never remove the terminal from the battery without fully loading the generator, otherwise the voltage regulator will fail.

If you listen to these tips, your generator will last longer.

If the generator is seriously damaged, it does not have to be repaired, but completely replaced. Parts necessary for repair may be missing, or the breakdown may not be repairable at all. Meanwhile, the on-board voltage and the quality of battery charging depend on the good operation of the power unit. It's a shame when, despite a good motor, electrical equipment does not work properly.

And if we are talking about VAZ cars, then sometimes a replacement is in demand due to the lack of power of standard devices. Modern automakers offer many additional devices that increase the level of comfort when traveling, but they also consume a large amount of electricity, and old devices cannot cope, so they have to be replaced with more powerful ones.

Procedure for disabling the immobilizer

Please note that if the immobilizer is disabled incorrectly, the car will be completely locked and only a specialist can restore its performance.

There are two types with which you can disable immo - mechanical and technical. The first involves simply cutting the wires, and the second involves reflashing the device. Since the second method is quite difficult and requires a lot of effort and certain skills, below we will tell you how to achieve exactly the same result, but faster and with a minimum of skills.

Step-by-step work order

1. We find the immobilizer control unit; as a rule, it is located directly behind the center console of the cabin, approximately at the level of the radio.

This is what the immobilizer looks like behind the instrument panel.

Next, when the immobilizer is removed, it is necessary to restore the line by installing a jumper in the ECU block.

VAZ cars: repair, maintenance, tuning

The standard immobilizer of the VAZ 2110 APS-4 car is equipped with two working keys with black marks and one training key with a red mark. Any operations with the standard immobilizer will be accompanied by light signals from an LED located on the vehicle’s dashboard and sound signals from a buzzer mounted inside the control unit. How to learn a working code key for the VAZ 2110 immobilizer, what to do if the working key is lost, we’ll figure it out right now.

Alternator voltage regulator for VAZ 2110 – replacing it + Video

The voltage regulator on a modern car automatically and continuously adjusts the excitation current of the generator. Moreover, this process proceeds in such a way that when the current load and rotation speed of the generator changes, the value of its voltage remains in a strictly defined range.

On a VAZ 2110 car, the voltage potential in the generator is formed under the influence of alternating current. This phenomenon becomes possible due to the presence of silicon diodes in the generating device of the vehicle. The generator rotor (the rotating component of the mechanism) operates according to the following diagram:

• First, the crankshaft begins to function, which is affected by the current;
• the crankshaft sets the movement of the rotor;
• After this, the generating device itself begins to work.

All stages of the sounded process are monitored by a voltage regulator, which is also often called a relay. It is this that is considered the main control unit of the generator.

Without a regulator, the current-generating mechanism of the VAZ 2110 will not perform its tasks, which are listed below:

• starting the generator;
• control (in offline mode) of current supply;
• “holding” in a certain voltage range.

The described relay cannot be repaired. In the event of a breakdown, the regulator must be replaced, which is done after checking the functionality of this unit.

How to check the relay on a VAZ 2110?

To analyze the condition of the regulator, you need to purchase a voltmeter, which has a measuring scale in the range of 15–30 volts. The check is performed as follows:

• start the car engine at medium speed and let it run for a quarter of an hour (the operation is carried out with the headlights on);
• A voltmeter is used to determine the voltage between the “ground” of the generating device and the “plus” on the battery.

If the measurement shows a voltage value from 13.5 to 14.2 volts, replacing the regulator is not necessary. But in situations where the voltage has a different value, indicating a constant overcharging or undercharging of the battery, the relay needs to be replaced.

You can also remove the voltage regulator and check it together with the generator brush holder. To do this, a 12-volt light bulb with a power of 1–3 watts is placed between the brushes, a power source is connected to the “ground” and the positive terminal of the battery, from which a voltage of 12 volts is first supplied, and then 16 volts.

If the light comes on at 12 volts and goes out at 16, replacing the regulator on a VAZ 2110 is not necessary. If the lamp does not light up, this indicates that there is no required power contact between the relay terminals and the brushes, or that a break has occurred. And the burning of the lamp at 12 and 16 volts indicates a breakdown of the regulator.

How to replace the generator voltage relay?

If you have some skills, removing and disassembling the mechanism described in the article does not cause difficulties for a person. The most difficult thing is to change it for the first time, and subsequent replacements, as a rule, take place quickly and without problems.

The regulator on a VAZ 2110 is dismantled according to the following scheme:

• disconnect the negative terminal from the battery;
• disconnect the drive block from the terminal marked “D+”;
• unscrew the nut, which is located under the rubber boot (it needs to be moved a little to the side);
• disconnect all existing wires in the contact pin;
• unscrew the nut in the generating device circuit (this fastener secures the terminal) and remove it.

Then you will need to remove the generator casing by unscrewing the nuts (there are three of them) that hold it in place, as well as dismantle the relay housing and remove the screw securing the disassembled mechanism from the rectifier compartment. Now the VAZ 2110 voltage regulator can be easily removed. You can install a new device instead. After replacing the relay, all the described steps are performed in the reverse order.

Three-level generator voltage regulator for the “ten”

When the heating system, headlights and other additional loads are turned on on the VAZ 2110, the car battery discharges very quickly. This phenomenon is observed even when the “native” generator relay is functioning normally. A three-level regulator allows you to get rid of this problem. You can purchase it at any auto store, equip yourself with a simple set of tools (terminal pliers, a knife, an S10 open-end wrench and a Phillips screwdriver) and install it on the car yourself.

The three-level mechanism is mounted as follows:

• first remove the old relay according to the algorithm given above;
• grind the ends of the spacer bushing using a file (this operation ensures more reliable contact with the diode bridge);
• a new element with a brush holder (sold as a set) is installed in place of the relay;
• Sealant is used to seal the cable entry point;
• put back the plastic casing;
• lay the cable along the standard wiring to the area where the relay is mounted, and secure the new wire tightly with small plastic clamps.

It is recommended to connect the housing of the installed voltage relay and the autogenerator using a reliable shunt. This ensures the necessary contact of the device with ground. However, you can do without a shunt.

The mounted three-level mechanism should be checked with a tester at full consumer load (window heating, stove, headlights, etc. are turned on). At maximum, the device should show 14.5 V, in normal mode - 14.1 V, at minimum - about 13.4 V.

Immobilizer VAZ 2110, operating principle

The immobilizer on cars of the tenth family consists of a control unit, a status indicator on the control panel, two working black keys and one training key with a red mark.

Immobilizer of the VAZ-21101 (APS-4): 1 - control unit; 2 — status indicator; 3 - code key.

The location of the VAZ 2110 immobilizer unit is shown in the figure below.

Location of the immobilizer control unit in the passenger compartment of a VAZ-21101 car: 1 - control unit; 2 — control unit of the door locking system; 3 — bracket for fastening electronic units Location of the immobilizer status indicator on the VAZ-21101 instrument panel: 1 — immobilizer status indicator

The immobilizer control unit is connected to the controller via a diagnostic line. In this case, the control unit can detect the connection of the DST-2M diagnostic device, breaking the diagnostic circuit. The electronic engine control unit and the immobilizer can be in one of two mutual positions:

1. With the protective function turned off, then the immobilizer is considered clean, providing the ability to start the engine with any key, bypassing all immobilizer functions (steering column locking, etc.).
2. With immobilizer function enabled. In this case, starting the engine is possible only after sending an enabling signal to the engine control unit from the immobilizer. Automatically, this means that a trained key, already familiar to the immobilizer, is used to start the engine.

Initially, the immobilizer is in a “clean” state, allowing you to use any key to start the engine. But immediately after learning the key, the anti-theft device goes into security mode. After the key learning procedure, the transition to a pure state is not possible. To do this, it is necessary to change both the immobilizer itself and the electronic engine control unit.

By training the key, we generate a new password, which is written in the memory of the immobilizer and the engine ECU. The password is stored in the energy-protected circuit of the electronic engine control unit, in the immobilizer unit and in the key. In this case, the training key with a red mark cannot be used for any other pair of immo-ECUs. When the immobilizer is transferred to the trained state, the password is written to both working keys. It is these keys that are recommended to be used during vehicle operation, and it is advisable to store the training key with a red mark in a safe place.

Generators for VAZ 2115

VAZ 2115, created on the basis of the “nine”, adopted the main components and assemblies from it. Accordingly, there are also many problems with equipment. If the car has a carburetor engine, it can be equipped with a 55 A generator 37.3701, which differs from the above in the mounting method. However, this voltage is not enough for the constant use of modern audio systems, fog lights and other energy-consuming options. Which generator is better to install on a VAZ 2115 - car owners definitely recommend installing it with a power of at least 80 A. Now on the VAZ 2115, as well as on 2113-2114, three-phase 94.3701 with an output of 80 A are installed.

For more power, you can install a 90 A Priorov generator KZATE 9402.3701 in 2020, which is suitable for the mounting and pulley. A reliable unit will provide you with the necessary energy for any number of energy-consuming devices.

Summarizing the above, it can be noted that when buying a generator at a VAZ to replace a broken one or to increase power, it is better to choose Russian models, since they are most suitable in design and you will not have to carry out expensive modifications. In addition, you will always find the necessary

The generator is the power of the entire system of functioning of a single, albeit artificially created, organism called a car. It is specially designed to convert mechanical energy into electricity. But, like all components of any car, the generator on the VAZ 2110 performs its duties, which there is simply no one to do for it.

How to train working keys for the VAZ 2110 immobilizer

For the APS-4 immobilizer, it is possible to train no more than two working keys. Moreover, these keys had to be used only with a specific immobilizer, or not be trained at all. To train a working key, just perform a few simple operations:

1. Turn on the ignition. In this case, the signal LED should light up with a constant light no later than after 5 seconds.
2. We bring the original training key to the immobilizer indicator, while using the other key we turn off the ignition. The device should emit a short beep and the LED indicator should remain lit.
3. We remove the training key from the LED indicator 5 seconds after turning off the ignition. In this case, the indicator should go into continuous flashing mode with a frequency of 10 times/second.
4. Over the next 20 seconds, we bring the learning working key to the LED indicator. We hold it in the area of ​​the indicator until the buzzer emits a sound signal lasting about a second and the LED indicator stops blinking, signaling the end of the learning process.
5. We train the second working key in the same way.
6. After training two working keys, the LED indicator will continue to flash ten times per second until we bring the training key with a red mark to it.
7. After this, the LED lights up with a constant light and stays on for ten seconds. During this time you need to have time to turn on the ignition. The buzzer will emit a confirmation signal and the LED will go off.
8. We wait about 6-7 seconds and check the system. To do this, turn on the ignition, the LED indicator will flash twice per second, try to start the engine - it should not start. Otherwise, we carry out the key learning procedure first, turning off the ignition for at least 15-20 seconds.
9. Turn off the ignition and hold one of the working keys to the LED indicator. The buzzer gives two enabling signals, after which the engine should start.
10. Turn off the ignition, get out of the car by opening and closing the driver's doors. After 15-20 seconds, the buzzer emits a sound signal with a constant increase in volume, which indicates the successful completion of the training procedure. The immobilizer has switched to vehicle security mode, the LED indicator continues to flash every 2.5-3 seconds.

The trained key is lost. What to do

If the trained key is lost, it is necessary to re-train the remaining key. This is necessary to prevent an attacker from using the found trained key. The procedure for learning the remaining key (or a purchased new one) is carried out according to the same scheme, with the only difference being that the LED indicator at the beginning of the learning process does not light up constantly, but blinks at a frequency of 2 times per second.

Chip key VAZ 2110

If the training key with the red mark is lost, you will have to change the immobilizer-electronic engine control unit pair and retrain the purchased keys. Training a clean immobilizer and keys is carried out in the manner described above. Using the same scheme, a failed immobilizer is replaced, having a red training key and two black working keys available.

Functions performed

So, what is a generator for? First of all, in order to provide all VAZ 2110 equipment that runs on electricity with energy. Perhaps someone thinks that this is the battery's task. Not really, because the battery is needed to maintain functionality when the engine is not running (it starts the engine, supports the alarm, music system while parked, etc.).

But when the engine has already started, with the help of the battery, the generator comes into play. During the trip, it is he who supports the operation of all electronics, air conditioning, audio (or even video systems), and everything else that you have added to your VAZ 2110.

Another equally important function of the generator is charging the battery. This also happens when the engine is running. And if it weren’t for this device, the battery would not be able to cope with its tasks, and it would have to be charged all the time.

Considering that today on the VAZ 2110, in addition to the standard layout, many additional energy consumers are installed, it happens that the generator voltage is not enough. In this case, it makes sense to install a 120 amp generator.

How to check the immobilizer of a VAZ 2110

If the APS-4 immobilizer on a VAZ 2110 malfunctions, its functionality can be checked based on the sound signals of the buzzer. To do this, turn on the ignition. Six seconds after switching on, the LED indicator begins to flash for 20 seconds. In this case, the buzzer begins to produce a series of sound signals:

1. If the buzzer emits one long beep, this means that the key code has not been read. This may be due to a faulty transponder in the key or a faulty coil in the ignition switch.
2. Two continuous beeps from the buzzer will indicate that the electrical connection between the immobilizer and the engine control unit has been lost.
3. Three continuous beeps indicate that the key issued an incorrect code.
4. Four signals will indicate that the immobilizer has already been trained, but paired with another engine control unit.

Replacing the original generator with a more powerful one from other car brands

If the power of the generator does not satisfy you or it has simply failed over many years, then you can change it:

1. For an ELDIX 115A brand generator intended for Niva-21214. To install it you will need:

• generator;
• generator mounting bracket 21214;
• tension bar 21214;
• generator mounting bolt 2110-3701376 with nut;
• bolt M 8×25 with nut 2110.

The installation itself does not present any particular difficulty if you know how it is done, otherwise it is better to contact a specialist.

It is a good generator, according to consumer reviews.

1. Generator KZATE 2110-12; 2108-09 14V 90A from a Russian manufacturer is good because all its connections are made with bolts, the relay-regulator is also bolted, which makes it easy to maintain and repair the generator. The diode bridge on this generator is not soldered, but is connected by pressing. Thanks to this, the diode bridge can be replaced without removing the generator from the car. In addition, all components of this generator can be purchased without problems, since the manufacturer provides the domestic market with components.
2. Generator from Priora Lux KZATE 115A - manufacturer is the Samara plant named after. A. M. Tarasova. This model is attached to the VAZ-2110 with bolts. The wiring will require minor modifications. You will have to drill out the positive terminals that fit onto the generator. It is best to take a belt from BOSH, it has already been tested by many owners at random. Once connected, the new generator produces excellent performance:

• voltage with all consumers turned on – 13.8 V;
• The generator operates almost silently.

1. The Start-Volt 120A generator is a new generation of generators that allows you to connect any number of consumers, which, with the current level of technology development, have become simply necessary, and the power of a standard generator is clearly not enough. With the same dimensions and weight as standard generators, the power of Startvolt generators is 50% higher than conventional ones. Due to a fundamentally new approach to the configuration of the Start-Volt 120A generator, not only power has been increased, but also durability; they will last longer than usual without requiring repairs or replacement of components.
