Now regarding the connectors. Many people burn out 2 TsBKE on Kalina, some even burn out the wiring. Previously, no one could find connectors for these blocks, so I did it!

After restyling, instead of fuses and numerous relays, the Lada Kalina is equipped with a central body electronics control unit (CBEC). The device is available in “Lux” and “Norma” trim levels.

Programming the duration of control pulses

Even if the alarm is connected correctly, it is not a fact that the owner will be able to control the locks from the key fob. The point is that it is necessary to correctly select the duration of the control pulse (for locking and for opening). There is no need to make it too large so as not to overheat the actuators.

See what exactly the manufacturer Starline offers. We can set the pulse duration to 0.7 s, which should be enough. The value “3.6” will be redundant at the same time.

The “Lux” package has the following property: after 15 minutes of inactivity, the electronics “fall asleep”. It may take an extra boost to wake her up. So, try to use the option that provides for a double pulse. The main thing is not to activate the “comfort” option, which uses a 30-second duration. To connect the signaling with “comfort”, you need to install an additional unit in Grants (AvtoVAZ does not produce it). We wish you success.

Is the comfort block on the luxury grant being treated or is it only for replacement?

I may blurt out off-topic, what is wrong with it, either the relay is jammed - change it if it is done on the relay, which I am 99% sure. or the relay control is faulty. If you want, I’ll look behind the scenes, the main thing is that without this module the turn signals don’t light up)))

and if there is a diagram for connecting the wires, it will also not be superfluous. PM contacts.

If only it were that simple. In the luxury version of this car, there is no turn relay on the seat (in the steering column relay/fuse block, F5 is empty), as I understand from the Internet, it is “tied” to the comfort block (the link to which was given above).

In response to: Actually the question is on topic, a question for auto electronics engineers. Diagnosis: three yellow left turn signals are on (constantly) (both when the car is running and when the car is turned off), so far I solve the problem solely by removing the terminal and closing the car manually with the key. The dealer (the car is under warranty) does not have this unit in stock, they sing about the uncertain delivery times from AvtoVAZ, they are ready to solve the problem at their own expense, the issue is the price. You can do it in person or publicly.

Lada Granta control units and their problems

ECU – electronic control unit. It processes information about the state of the car and controls the operation of all systems. Data for processing comes from sensors that are installed in different components of the machine. The comfort of travel and the power of the car depend on how the unit’s software works. In fact, the ECU is the brain of the car.

At StoVesta you can have your car serviced and also purchase all the necessary spare parts and accessories.

What blocks are installed on the Lada Granta?

ECUs M74.5, M74 and M74M are installed on Lada Granta. Which unit is included in the car depends on the year of manufacture and engine type.

Until 2022, units M74 and M74.5 were installed.

The software for the M74 was developed by AvtoVAZ. There are 5 block options and more than 50 software. But there are no fundamental differences for the driver in these blocks and software.

The software for the M74.5 block was developed by NPP ITELMA. This unit is installed only on machines with engine 21127. The differences with the M74 are in appearance and connectors.

Starting from 2022, the Lada Granta began to be equipped with an M74M ECU. The software was developed by AvtoVAZ and this unit became a clone of the M86, which is installed on Lada Vesta, Khrey and Largus.

The software of all blocks is different and it is impossible to upload, for example, M74 or M74M software into the M74.5 block.

Any of the software options provided by the Lada Granta manufacturer does not make the car settings optimal. For example, the gas pedal does not always respond quickly to driver inputs. Or gears change for a long time and with jerks. You can improve the car's reaction speed, its power and smoothness with the help of chip tuning.

Weaknesses of Lada Granta control units

Firstly, the weak point of any Lada Granta control unit is its leakage and installation location. The ECU is located under the glove compartment, behind the upholstery.

With this arrangement, there is a high probability that liquid will enter the block. In what cases can this happen:

• Antifreeze will get into the ECU if the interior heater leaks.
• Water from under the hood if the rubber plug dries out.
• Water if the drain hole at the bottom of the windshield becomes clogged.

If liquid gets inside the unit, it will fail. In this case, the car simply will not start. And if this happens during a trip, then anything can happen. But the unit will definitely not work correctly, and the trip will turn into torture.

Secondly, the weak point of any Lada Granta unit is poor protection against theft. This is especially true for the M74M block. It is easy for a hijacker to find the block and either reprogram it or replace it with a pre-prepared one.

How to protect the ECU from liquid?

To avoid troubles with liquid getting inside the Lada Granta control unit, just do the following:

• Place the plug on the sealant that leads to the ECU from under the hood.
• Regularly clean the drainage holes located under the windshield.
• Move the control unit higher, closer to the passenger airbag. But we recommend doing this at our service center.

These actions are enough to protect the control unit from liquids.

How to protect the ECU from hacking

There are two directions of protection - mechanical and electronic.

In order to protect the ECU mechanically, it is enough to place it in a safe. The block remains in the same place, but access to it becomes much more difficult. An attacker will not be able to quickly replace the ECU or disable the standard alarm system. The safe will also seal the block from moisture, but such protection cannot be called reliable.

For electronic protection of the unit, we recommend chip tuning. This will not only prevent the ECU from being hacked electronically, but will also make the car more powerful and more comfortable to travel with.

Now the Lada Granta is a very popular car. And the more they buy it, the more they steal. Therefore, we advise you to take the safety of your car seriously and additionally protect it from theft.

Of course, a safe on an ECU will not provide 100% protection, but it will significantly increase the time it takes to bypass the anti-theft system. And for an attacker it is important to do everything quickly. Therefore, faced with such mechanical protection, the hijacker will most likely simply give up.

To further secure the car, you can install additional alarms and mechanical protection.

Solution

If such a problem happens to you, it is recommended to contact the Lada dealership. In this case, you should not count on warranty service, since in this case there is no fault of the plant.

The thing is that the resistance of the diodes is greater than that of standard lamps, which is why the electronics unit burns out. In this case, there is a reckless decision by AvtoVAZ designers, who abandoned fuses and installed an electronic unit from the Renault Trafic model in Vesta.

Vesta’s design uses this electronics unit.

To restore the operation of the electrics, it is necessary to replace the additional body electronics unit of the Lada Vesta.

Replacement instructions

First you need to remove the instrument panel on the center console, then remove the lower part of the dashboard trim under the steering wheel. Now you need to unscrew the fuse box and turn it so that it takes a horizontal position. You need to stick your hand into the freed space until it comes into contact with the shelf on which the TsBKE is installed.

By unscrewing the fixing bolt, you can pull up the control unit and, after disconnecting the two electrical connectors, carefully pull it out. After dismantling the device, it is repaired or replaced with a new one. Installation of the device is carried out strictly in reverse order.

The introduction of modern technologies in the field of control of electronic equipment of a car makes the driver’s work easier, frees him from unnecessary loads and reduces the likelihood of road accidents. Along with the positive aspects of the implementation of CBKE, there are also a number of disadvantages associated with the unreliability of some nodes.

The electrical package control unit (pictured below) Kalina Lux does not work. Or rather, it does not respond to my clicks. It is illuminated, when I press the buttons, click, I hear a single short sound in the area of ​​the speedometer/heater (you can hear it in the video below). This thing appeared in the morning, I walked away for an hour, everything worked.

How to remove cbke? repair of faulty pulp and paper plant

So, CBKE (eng. BCM - Body Control Module) - the Central Unit of Body Electronics is located in the car interior, on the left, above the fuse box.

You can view the pinout of the TsBKE, a description of its functions and the diagnosis of its malfunctions by following the link - TsBKE - Purpose, Functions, Diagnostics (*.pdf format, size

To dismantle it, according to AVTOVAZ technological instructions, it is necessary to remove the instrument panel. Not the instrument panel, with gauges and indicators, but the entire panel! Something like this.

26.1MB). Information on removing the CBKE is on page 281.

On our own behalf, we can add that it is difficult to remove the TsBKE without removing the instrument panel. And installing it back in its place, securing it as it should be, is even more difficult, but possible. The Internet is full of instructions, everyone can make it up, just like we can in our own way.

We had to remove the body electronics unit because the left turn light was constantly on. All paths and electrical circuits led there. There was no turn relay in this Lada Granta.

Block number 21900-3840080-20.

From the inside, the TsBKE board looks like this. Next to the large gray connector, the “culprit” of the constantly lit direction indicators is the BTS-5242-2L microcircuit (power key).

You can get acquainted with the “datasheet” of this microcircuit by following the link: Datasheet BTS-5 242-2L (*.pdf format, size

In general, in terms of repairs, there are no tricks. Either we order and change the microcircuit, or we order and change the TsBKE.

Regarding replacing the block. According to the document “CBKE - Purpose, Functions, Diagnostics”, there is also a unit with number 21900-3840080-10, but it does not control the electric drives of the side mirrors, does not have auto lights, does not control the rear windows and does not control the trunk lighting.

Purpose and characteristics of pulp and paper

The central unit of body electronics Kalina 2 controls:

• alarm system;
• windshield wipers;
• heated windshield and rear windows;
• heated side mirrors;
• lighting system;
• direction indicators;
• central locking;
• trunk opening drive;
• electric windows;
• heated front seats;
• electric side mirrors.

When the alarm is turned on, an automatic check occurs, accompanied by a short flashing of the direction indicators. In security mode, the immobilizer light on the instrument cluster blinks. The security mode is disarmed by pressing the remote control button.

The central electronic unit automatically turns on the windshield wipers if:

• a signal was received from the rain sensor;
• sensitivity regulator in position from 1 to 4;
• The wiper switch is in the intermittent position.

If a malfunction is detected in the operation of the windshield wiper, TsBKE Kalina 2 switches it from automatic to manual control mode. When the windshield heating function is turned on, the body electronics monitor the on-board voltage and limit the heating duration to 6 minutes. When the voltage drops below 12 V, the CBKE switches off the heating mode.

When the voltage drops to 9.6 V, the central unit limits the operation of the rear window and side mirror heaters. This prevents the engine from going into emergency mode. When the voltage is restored to a level of 10.8 Volts, the heaters turn on automatically.

The driver is also assisted by body electronics when working with the lighting system. When the engine starts, the daytime running lights turn on, and when the engine stops, they turn off automatically. The low beam headlights and side lights turn on when a signal is received from the light and rain sensor.

Central unit of body electronics Kalina 2 and Lux ​​and its “diseases”

Auto manufacturers today use many technological solutions to ensure more comfortable driving. One of such devices is CBKE. What is the central unit of body electronics Kalina 2 needed for, what functions does it perform and what malfunctions are typical for it - read in this article.

Non-specific types of services

Even if the rules for safe operation of the vehicle are observed, the heater control unit may require servicing or replacement. This happens as a result of sudden switching of the heating knob of the Lada Kalina car. The operating instructions indicate that you must wait until the system warms up to a minimum, otherwise expensive repairs will be required.

From a financial point of view, the stove control unit will not be cheap, so its careful operation will save the family budget.

The heater control unit cannot be replaced independently due to the need to use special equipment. Much less often problems arise at the level of the engine control system.

The need to visit a service station will be caused by driving on a gravel road, an accident, or the result of unprofessional maintenance. The engine management system is responsible for fuel injection, so any deviations in its operation immediately put the car on hold. How long it will take to replace the engine control unit will be decided by the technician after an inspection.

It is cheaper, but repairs take much longer when the body electronics unit comes under attack. The problem can only be diagnosed in a service center. The duration is due to the fact that if the engine control unit can be replaced as a single whole, then part of the wiring must be changed along with the electronics.

Voltage surges or a simple short circuit can damage a certain sector. The light control unit will be the first to tell you about this.

Incorrectly working turn signals or emergency lights are the first sign indicating a failure in the electronic component of the car. There is no point in delaying a visit to the service center. Otherwise, the ESP unit responsible for dynamic stabilization will come under attack. Even with minor problems, the driver will notice a decrease in the lateral dynamics of the vehicle.

New Lada: Lada Vesta AMT Stepway

Lada Kalina requires regular maintenance as prescribed by the manufacturer. If the specified deadlines are met, each element of the system will work properly.

Functions

The electrical package control unit is designed to perform the following functions:

1. Alarm. If the car's anti-theft system detects a break-in attempt, thanks to the CBKE, it will transmit information about this to the car owner's control panel.
2. Windshield wiper system control. Moreover, we are talking about both manual and automatic control (if the car is equipped with an electrical package control unit marked 21900-3840080-20).
3. The device performs the function of controlling the windshield and rear window heating systems. This unit also controls the heating elements of the side rear-view mirrors.
4. The electrical control unit also monitors the performance of the optics, both in manual and automatic control modes. In particular, we are talking about low-beam headlamps, side lights, and DRLs.
5. Separately, we should highlight the function of ensuring the functionality of the high-range lighting.
6. Turning lights, as well as light signaling.
7. Vehicle interior lighting.
8. The device monitors the performance and energy saving of devices belonging to the category of internal lighting of the car.
9. Monitoring the state of the central lock, as well as performing the functions of locking and unlocking the locks themselves from the key, from buttons installed in the car interior, as well as in the doors.
10. Another option is to open the luggage compartment lid using a button installed in the cabin.
11. An equally important function is the control of electric drives, in particular, we are talking about power windows, as well as side rear-view mirrors.
12. Heating system for driver and passenger seats.
13. Luggage compartment lighting unit (video author - Vladimir Kostyuchenkov).

Typical faults

If the electrical package control unit fails for some reason, this can lead to the following problems:

1. Failure to operate power windows. Of course, before disassembling the control module, you should make sure that the window regulators do not work precisely because of it. It would be logical to first check the safety element, as well as the lift control unit, which is built into the driver's door. In practice, it often happens that the cause of power window failure is poor wiring contact on the unit itself.
2. The optics stopped working - low beam, turn signals, etc. In this case, the safety elements, light sources and steering switch are first checked. There is a possibility that the reason lies in a broken contact directly on the switch; if this is the case, then they should be re-soldered. If the reason is that the unit is not working, it will need to be dismantled and disassembled in order to find the burnt-out element and re-solder it. If soldering does not help solve the problem, the device will have to be replaced.
3. Some of the equipment has stopped working, while the devices, as at first glance may seem, are in no way connected with each other. The fact is that the module itself includes many elements and controllers, each of them is responsible for performing certain functions. If two or more controllers fail at once, it can cause serious damage. For example, the optics, heated rear and front windows, the trunk door and the window regulator will immediately refuse to work. It is necessary to locate the failed controller and replace it by re-soldering.
4. A fairly common problem that can occur is a break in the wiring of the unit. It is installed in a virtually inaccessible place, but if electrical work is being done, for example, installing an anti-theft system, then most likely the car owner will encounter a TsBKE. And if the wiring is damaged during the work, of course, this will affect the functioning of the device and, accordingly, the performance of certain functions.
5. Oxidation of contacts on module connectors. If you encounter such a problem, we recommend paying attention to the humidity in the cabin. Often, oxidation at the outlets occurs precisely as a result of high humidity. The contacts can be cleaned, this is not a problem, but the problem of humidity must be addressed, since otherwise it can lead to failure of the microcircuit as a whole.
6. Board failure. The most terrible problem for the car owner, because because of this the device simply will not be able to work normally. Accordingly, it will need to be replaced, and this, in turn, costs a lot of money (author - Alexander Fisher).

Connecting the signaling to the central locking system

Now we get to the most interesting part. The contacts of the signaling relay must be connected to the gap in the brown wire (see diagram in Chapter 1). Moreover, this will be required regardless of the configuration. Oddly enough, we won’t need power cables at all. And the task now looks like this: you need a two-wire signal cable connected to the break in the brown cord.

The moral here is:

1. If you were able to remove the central lock control unit, connect the cable to the break in the wire connected to pin “7” of the control unit;
2. If you have removed the door trim, then pull the cable out of it (from the point where the brown cord breaks).

It is clear that the second side of the cable must reach the relay connector of your alarm.

Option for the “Lux” package

So, this means that there is a button on the armrest in the cabin that allows you to lock the locks. From one of the contacts of the button, to which a “plus” is applied when pressed, you need to stretch the cord to the signaling unit. Nothing else is required, and you can connect the alarm according to the following scheme:

According to reviews, this option is suitable if we are talking specifically about the “luxury” configuration. By the way, the resistor can be connected to the gap in the wire designated “blue” (the common contacts are then connected with a jumper).

It must be remembered that when working with any electrical equipment, you must first remove the negative terminal from the battery.

Each cord that is re-laid must not touch metal surfaces. Otherwise, in places of contact, the wire is protected with a tube that can withstand temperatures of 250 degrees. This is how you can protect yourself from unforeseen consequences.

Option for the “Norma” configuration

Let's say there is no button in the cabin that allows you to perform emergency closing. Then you need to connect the signaling to the central locking system according to the following scheme:

As you can see, unlike the first option, there are no resistors here, and positive voltage is not used at all. But in the luxury configuration the effect that is characteristic of this scheme will not be observed:

• We perform closing from the key fob - all locks are locked;
• We try to open the locks with the key fob - only the driver's lock unlocks.

If you are satisfied with this property, try to implement the scheme in practice. And other options, more advanced, look much more complicated.

Read what is said about installation safety in the previous chapter. Do not neglect the advice about disconnecting the negative terminal. We work only with signal circuits, so nothing will fail even if connected incorrectly. However, be careful not to confuse the locking and unlocking relays, which are located in the alarm unit. This unit is usually equipped with a 6-pin connector (for details, see the signaling manufacturer's instructions).
