Lada Kalina ECU: Location, Replacement, Transfer, What are they?

Sometimes situations occur when a malfunction appears in the electronic control unit (or brains) of the Lada Kalina model. This can often be caused by spilled antifreeze, since the control module is located in a very unfortunate place, namely under the radiator of the heating system. Even the most careful owner of a domestic small car cannot prevent such a problem. Many people are interested in whether it is possible to transfer the ECU?

Location

The ECU on the Lada Kalina is located under the center console of the car. You can see it by removing the side cover of the front passenger's footwell air duct. The block is attached to a bolted connection and securely fixed in its place. The connectors of the unit are also tightly inserted into their place and secured with a special lock, which prevents the connector from spontaneously disconnecting from the ECU.

It is quite difficult to call this location of the engine control unit successful, since it is located exactly under the heater radiator and if there are leaks in the heater radiator, the coolant gets directly onto the engine block, which causes irreversible consequences and, of course, a breakdown or short circuit.

In some cases, there is a coolant leak at the ECU, it can be repaired, but most often it is necessary to replace the unit.

Diagnosing the block

After dismantling the liquid-filled module, we inspect it. To do this, take a screwdriver with a star tip and unscrew the 4 small screws. Next, we slowly remove the control board, with which we also perform a thorough visual inspection.

The most common reason for device failure in such a situation is a burnt-out output key of the Lada Kalina ignition coil control circuit. Repair won't help here. After such a malfunction occurs, the engine begins to function on only two cylinders, and in some situations it is not able to start at all. This is where qualified service will come to the rescue. Specialists will dismantle the damaged component, wash and dry it.

The second common cause is burnout of the board itself. This fact is revealed quite simply. There will be a characteristic darkening of the surface of the board, which will eliminate all doubts.

Will repairing the ECU help in this case? The answer can only be heard in a specialized workshop. From experience, we note that the probability of help from repairs tends to zero. Will need replacement.

Sometimes there is a situation related to minor damage to the ECU circuit. In this case, the owner can get away with little expense. To “reanimate” the module, you will need to perform a number of repair procedures, namely:

wipe the device with a dry cloth;
apply repeated washing with WD-40 and blow with a stream of compressed air;
rinse again, but with alcohol and also blow with an air stream;
Dry (thoroughly) for at least 2 hours.

Some Lada Kalina owners believe that replacing the ECU is a faster and more cost-effective process compared to washing and drying. Experience has shown that the situation is the opposite. Here the determining role is given to the price factor. The new ECU will require considerable financial resources from the owner of LADA Kalina. The situation is aggravated by the undesirability of installing used “brains”. Often, a used version of the unit will be cheaper, but there is a likely risk of it not working.

Why doesn't the ECU work?

ECU chip filled with antifreeze

Quite often problems occur that the engine control unit stops working; to find out the reason for the failure of the ECU, you need to inspect it:

Check to see if the connector has come loose from the unit; this happens quite often after installing a radio, or replacing a heater radiator, etc.
Check for ground on the block. Sometimes it happens that after some work, a person forgets to fasten the mass necessary for the operation of the unit.
Check for signs of coolant leakage on the engine block.

If such problems are not found, it is necessary to dismantle the engine block and troubleshoot, repair or replace it.

Let's sum it up

If symptoms appear, the owner of LADA Kalina should contact service as soon as possible, because the cost of repairs can be significantly reduced. It is advisable to independently carry out the procedures we have indicated if the owner of LADA Kalina has a sufficient level of experience in dealing with automotive electronic devices. To do this, at a minimum, you need to know where the ECU is located, as well as how to remove the ECU. However, a 100% positive outcome of the event should not be expected. In case of failure, we recommend contacting the service specialists.

Replacing the ECU

Replacing the engine controller on Kalina is quite simple according to the instructions presented below.

Remove the negative terminal from the battery;
Unscrew the cover of the side air duct of the front passenger's feet;
Disconnect the connectors from the controller;
Unscrew the screw securing the ECU on the left;
We take out the controller by pulling it towards ourselves, as if on a sled;
Unscrew the controller from the pad;
Installation is carried out in the reverse order;

If the controller malfunctions, a “clean” controller must be used for replacement.

Functions

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

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.
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).
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.
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.
Separately, we should highlight the function of ensuring the functionality of the high-range lighting.
Turning lights, as well as light signaling.
Vehicle interior lighting.
The device monitors the performance and energy saving of devices belonging to the category of internal lighting of the car.
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.
Another option is to open the luggage compartment lid using a button installed in the cabin.
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.
Heating system for driver and passenger seats.
