Controller (ECU) 11194-1411020-30 for Kalina

Design and purpose of the Lada Kalina ECU

The electronic control unit is also called a controller. Its main task is to collect information from all sensors, process it and then issue appropriate commands to the executive nodes. The ECU is an element of the on-board network; it continuously exchanges data with other systems, for example, APS (traction control system), automatic transmission (automatic transmission), security system, air conditioning system, etc.

The controller is a visually small chip, but its structure is quite complex. The ECU has several types of memory:

1. PROM. Contains all executive control circuits and is responsible for fixing commands in accordance with a certain sequence. This memory contains calibration data or a standard for setting up the operation of all processes depending on the power and type of power plant, as well as other parameters (weight, transmission, etc.). The EPROM does not depend on external power sources; even if the on-board network is completely de-energized, all information will be saved.
2. RAM. Memory, which is completely dependent on the on-board power supply, if this condition is violated, all information is deleted. As a rule, these are diagnostic codes and data necessary for the ECU to carry out calculations.
3. EPROM is an electrical programmable memory device. Immobilizer combination codes are stored here. If this data is not in memory, starting the engine will not be possible. The system does not depend on power, information is saved permanently.

The controller is a multifunctional device. It not only controls the operation of the engine, but also protects the car from unauthorized access.

Location of the ECU in Lada Kalina

The electronic control unit is located under the center console on the driver's side. To access it, just remove the protective panel. It is worth noting that the location for the ECM was chosen very poorly. The ECU under the console often fills with coolant, because the heater radiator and hoses are in close proximity. Therefore, many motorists strive to move it to a safer place as soon as possible.

How does the ECU work?

The data that comes from sensors contains various characteristics. For example, a mass air flow sensor (MAF) collects and transmits data on the volume of air entering the system - the more air the engine consumes, the higher its dynamic characteristics. If the indicators are overestimated, this will inevitably lead to increased fuel consumption. The ECU on the Lada Kalina is able to track such deviations and report a malfunction to the owner, although it will continue to issue commands based on incorrect data.

The controller collects information about the following processes:

• position of the crankshaft and camshaft;
• incoming air temperature;
• error reset;
• vehicle speed;
• amplitude of body vibrations;
• on-board network voltage;
• coolant temperature;
• content of impurities in exhaust gases.

The ECU also transmits data about throttle position, fuel consumption, ignition angle and much more.

Where is the ECU controller located on the Lada Kalina

So, the Kalina engine control unit is located at the very bottom of the console, between the floor and the heating radiator. It is accessible from the passenger's feet.

To do this, you need to remove the plastic cover, which is attached with one screw. We unscrew it and move the lining forward along the direction of the car, after which it should completely disengage. We remove the cover to the side. Below it we see the following picture.

Main malfunctions and their causes

There are not many problems with the ECU. Basically, controller failure occurs due to a power surge in the network. Other possible system problems:

1. The device often fails due to mechanical damage. For example, the device received a strong blow or prolonged vibrations were observed, which caused cracks to appear on the soldered contacts and in other places.
2. The controller overheats due to strong temperature changes. For example, in winter, some motorists start the engine at high speeds, trying to ensure it starts, which results in overheating of the ECM.
3. Corrosion. Oddly enough, rust appears on the module due to frequent changes in air temperature and, as a result, the occurrence of large amounts of condensation.
4. Depressurization. For this reason, moisture gets inside, which leads to failure of the device.
5. Lack of communication with the control unit. Occurs after interference in the control system from the outside. This often happens when they try to “smoke” another car with a dead battery from one car. It is possible that while the engine is running the battery terminals are reset or the polarity is incorrect when connecting (the terminals are reversed). Less often, lack of communication occurs due to the starter starting without connecting power to it.

If the device fails for some reason, repair or replacement should be carried out only after comprehensive diagnostics have been performed. The nature of the malfunction may indicate problems associated with the functioning of other systems. If they are not corrected in a timely manner, repairing or replacing the module with a new one will lead to repeated failure.

Symptoms of ECU malfunction

If the device is not working correctly or there is no connection at all, then you can notice this by the following signs:

1. If there are obvious malfunctions, the Check Engine icon on the instrument panel does not light up or flashes intermittently at varying frequencies. You must first make sure that the light bulb is working properly and that it has power, and only then can you diagnose the ECU module.
2. When connecting a diagnostic scanner to the connector, the latter produces incorrect data that raises serious doubts. Simply put, the data is completely different from what it should be. If the controller fails, the scanner may not connect at all.
3. Engine malfunctions, tripping, the car does not start or starts with difficulty. However, there are no objective reasons for such phenomena.
4. Misfires when the ignition system is in good condition.
5. The fan in front of the radiator turns on spontaneously.
6. For no apparent reason, fuses burn out, and different ones. Usually fuses blow due to voltage surges in the on-board network or a short circuit in the circuit, but if the diagnostics do not reveal such problems, then the problem is with the ECM.
7. Pulses from the sensors do not arrive or arrive, but unevenly.
8. Incorrect operation of the gas pedal. This is especially true for the electronic pedal: when the driver presses it, it either does not respond or does so late.
9. Damage to the device body or contacts, for example, traces of burning on the terminal blocks.

A malfunction of the controller may be indicated by the absence of control signals for the ignition system, IAC, fuel pump and other devices whose operation is regulated by the electronic control unit.

Why the ECU on the Lada Kalina does not work - the main reasons

One of the most common problems that Lada Kalina owners encounter is ECU failure. Let's look at the main reasons for controller failure:

• Failure due to a short circuit in the on-board network. Here, you can get by with little effort and solder the main resistors, or it will lead to complete combustion of the element.
• If liquid gets on the unit panel, which will lead to complete failure. Usually the ECU is filled with antifreeze.
• Illegal actions of third parties that will lead to ECU failure.
• Other reasons not previously stated.

All these reasons will serve as a reason for diagnosing and dismantling the car control unit.

How the firmware is installed

The firmware process (software update) is as follows:

1. First, a complete diagnosis of the engine is carried out; if the engine is faulty, the firmware will do more harm than good.
2. The original firmware is saved and a modified one is selected based on it.
3. Using an adapter, new software is written to the ECU through the OBD II diagnostic connector (observing the pinout) using a special computer program.
4. The controller is rebooted and the functionality of all systems is checked.

At first glance it looks quite simple, but flashing the control unit on the Lada Kalina without special knowledge and skills is highly not recommended. In addition, you need equipment and the ability to choose the firmware so as not to cause harm. By contacting specialized organizations, you can not only get diagnostics and firmware, but also a guarantee of performance.

How to remove the ECU on a Lada Kalina - step-by-step instructions

In order to remove the ECU unit on a Lada Kalina, you must perform the following procedure:

1. First you need to unscrew 2 screws, the location of the first is shown by the arrow. The second is at the same level on the engine side. Before doing this, you must remember to remove the terminal from the battery. After unscrewing the screws, do you need to pull the block towards the passenger door? and he must leave from there along the guides. Sometimes it happens that the wires rest against the carpet. Then they need to be corrected.

2. In order to remove the connector and disconnect the unit from the wires, you first need to: pull the connector lock to the side. The latch is a bracket. I think you can easily find it on the connector.

ECU transfer

Every owner of a Lada Kalina car, especially those who have owned it for several years, is familiar with the problem associated with flooding the controller with coolant. Any leak in the heater core or loose connection of the hoses leads to antifreeze getting into the ECU. Even if such problems have not arisen until now, this does not mean that this will not happen at any time. Therefore, it is better not to wait for such troubles and move the control unit to a safer place in advance.

This is not difficult to do; all you need is a screwdriver and a few keys. The most common transfer locations are as follows:

1. Attach under the insulation just above the rug on the front left.
2. On the air duct above the glove compartment.

As a last resort, you can wrap the controller more tightly with plastic film or seal it with sealant. This option is not the most successful, since condensation will accumulate inside and the ECU will fail.

The ECU on Kalina is filled with antifreeze - what to do?

After the block filled with antifreeze has been removed, its initial inspection should be carried out. For these purposes, it is necessary to remove 4 screws using a star screwdriver. Then you should slowly remove the control board for a visual inspection. The most common failure is the burnout of the ignition coil output switch. In this case, repair will not help.

As a result of such a malfunction, the Lada Kalina starts working on only 2 cylinders, and sometimes refuses to start at all. You can cope with a similar problem in a stationary workshop. There they will remove the damaged element, wash and dry it. The second most common problem is board burnout. It is not difficult to detect such a defect: the characteristic blackening of the board will leave no doubt.

Is it possible to repair the ECU in this case? The answer to this question can only be given by a service center, but experience shows that repairs will not help here. A complete replacement is required. It happens that sometimes the brain circuitry is slightly damaged. If this happens, then the car owner can get off easy. To restore the car to working order, you will need some minor repairs:

1. wipe the block with a dry cloth;
2. rinse with WD-40 several times and blow it out with a compressor;
3. rinse several times in alcohol and blow again with a compressor;
4. dry well, otherwise the Lada Kalina will not move;
5. drying takes at least 1-2 hours.

Removing the ECU and installing it in a safe place

The whole job will take no more than an hour. Armed with a screwdriver and a 10mm wrench, we proceed to dismantling:

1. Remove the plastic cover on the front passenger side.
2. The controller is immediately accessible, but removing it is not so easy. First, unscrew the self-tapping screw with a screwdriver and try to pull the ECU towards you. If that doesn’t work, remove the cover from the driver’s side and apply pressure from that side.
3. After removing the ECU, you need to unscrew the mount on which it is fixed.
4. Now you can install it in a new location. As an example, the place under the glove compartment shelf was chosen.
5. Make three holes in the shelf for 5mm bolts in the same places as on the ECU. After this, screw the controller to the shelf.

When installing, you need to be careful not to damage the wires. In this simple way you can avoid possible flooding of the electronic control unit and problems associated with this nuisance.

The controller, or in common parlance the “brains,” on Kalina is one of the most important components of the car, it’s not for nothing that it received such a nickname. Without it, it is impossible to imagine the normal functioning of all vehicle systems. In addition, the ECU significantly facilitates monitoring the operation of the engine and on-board network, helping to timely identify faults and eliminate them.

ECU interchangeability on Lada Kalina

I will give a table of interchangeability of Kalina ECU

. This data was not verified by me personally, but by one authoritative master. The interchangeability of these blocks applies only to blocks with factory firmware (that is, after installation there is no need to reflash the block for your engine and sensors). So, in each line there is a block marking, firmware version and toxicity class.

1. Bosch 21114-1411020-40 with software B104CR01(02) Euro3 (in my cases it was this one) can be replaced with:
2. Bosch 21114-1411020-40 with software B102СQ05(CR06) Euro3;
3. Bosch 11183-1411020-02 with software B101CR01(02) Euro2.

There is one peculiarity here. If your car has an air conditioner, then the firmware version must be B104CR02 and no other, otherwise the engine will not compensate for the load from the air conditioner. But since in this article we are talking about a car without it, you can ignore the last 2 digits of the firmware.

All of the above Bosch blocks can be replaced with domestic Janvr7.2 and 7.2+ blocks.

Domestic blocks are all Euro 2, with the exception of M73 blocks - they are Euro3. January 7.2 and 7.2+ blocks manufactured by Avtel or Itelma (Euro2) for Kalina 1.6l 8V: 7.2 11183-1411020-21(22) with software A(I) 201CO56(57)(58); 7.2+ 11183-1411020-21(22) with software A(I)201CP57. These blocks do not support air conditioning, as I understand it. And, in fact, the M73 blocks, which are suitable for Kalina. These units are all Euro 3: M73 21114-1411020-41 with software A303CE05(CF06) Euro3 (support air conditioning); M73 21114-1411020-42 with software I303CE05(CF06) Euro3 (support air conditioning).

Thus, all of the listed ECUs with Euro3 toxicity class can be changed and can be changed among themselves without hesitation (only if they have factory firmware). It is also possible to replace a block with Euro 3 class with a block with Euro 2 class, but vice versa is not possible. All markings are located on a white plate glued to the ECU cover. Next, I consider it necessary to consider the option of replacing the unit with a used one that was installed on a car with an activated immobilizer, since in this case there is one unpleasant feature.
