2012 Chevrolet Cruze
Fault: missing dimensions, trunk, feet and cigarette lighter. No trunk relay control.
There are errors in the trunk and dimensions.

All of this is controlled by the electronic body control module - Body Control Module (B CM).
The ECU ID of this car is 13574841. Let's start the repair.
In most cases, repairing this computer is much more profitable than replacing it with a used one with registration and garters.

The body control unit in Cruz is located under the center console in the center at the front. In other words, on the floor under the radio.
Access for dismantling is from the passenger side.

This ECU contains the configuration of a specific car, as well as keys and wine numbers.
With someone else's ecu without registering your wine, pin, configuration and keys, the car will not start.
In some cases, when connecting someone else's computer to your car, you can get out of sync blocks and a big problem in restoring everything to its place.
It is strongly not recommended to connect an unprepared BCM ECU from someone else's car to your own.

We take out the ECU and, according to the electrical circuit diagram, call all the legs of the devices that refuse to work with us.
We find all the faulty channels and change the burnt out elements.
The system is checked for functionality, first on the table, and then on the car.

This defect is caused by an overcurrent in one or more channels controlled by the BCM ECU.
The most common is the installation of additional lamps on any of the channels or the installation of lamps not approved by manufacturers.
Less common a short circuit in the lamps. Even less often, a short circuit in the electrical wiring due to frayed wires.

Before installing another or repaired unit, you need to eliminate all the malfunctions that led to its failure. Otherwise, the defect will repeat itself in the near future.

I carry out all types of diagnostics of Chevrolet cars.
I repair BCM ECU, motor ECU, SRS ECU, etc.
Binding a used engine ECU or BCM.
I reset any ECU for tying new or used keys.
I perform mileage correction in all ECUs of this vehicle.

The cost of repairing an ECU is from 3000 rubles **.
The cost and possibility of repair can be accurately calculated only after diagnostics of all systems interconnected with this unit.
The cost of diagnostic work is not included in the cost of repairing an ecu and is paid separately.
On average, diagnosing the system, finding and eliminating the cause of the short circuit in the high-speed rail ECU costs between 1500-3000 rubles **.
The repair time depends on the availability of spare parts in each case. The procurement period for the necessary parts can range from 1 day to 3 weeks.
Most spare parts for these ecu are in stock. Whenever possible, I carry out repairs within 1 business day.

** All indicated costs of services are relevant for the year of writing the article and are not the final cost of work in each individual case.
Indicated for the concept of the order of value for a particular work.
