The error code consists of several characters.
Get into the car
Simultaneously press the accelerator and brake pedals to the floor
Turn on the ignition (but do not start the engine !!!)
If everything is done correctly, the mileage display will show the message "ECN" (error code number) and error codes. The first 4 digits indicate the error code. All zeros mean no errors are present; the interpretation of all other codes is provided below.
First character:
P - Powertrain codes - the code relates to engine and/or automatic transmission operation
B - Body codes - the code relates to "body systems" (airbags, central locking, power windows)
C - Chassis codes - the code relates to the chassis (suspension) system
U - Network codes - the code relates to communication between electronic control units (e.g., CAN bus)
Second character:
0 - Generic OBD-II code
1 and 2 - Manufacturer-specific code
3 - Reserved
Third character - Type of malfunction:
1 - Fuel or air metering system
2 - Fuel or air metering system
3 - Ignition system or misfire
4 - Auxiliary emission control
5 - Vehicle speed control and idle control systems
6 - ECU or its circuits
7 - Transmission
8 - Transmission
The fourth and fifth positions - Sequential error number
