The engine control module receives the gear ratio information from the transmission over CAN. If that information is missing or faulty, the code is set. It points to the transmission control module or to the communication with it, and the driver normally notices nothing.

Was Sie tun können

- 4After the repair, road test the car and check that gear changes are normal
