Co oznacza ten kod błędu?
The engine control module takes in data from the gearbox control module (TCM) over CAN. The fault code is set when messages are lost on the CAN network. It is stored first in the transmission control module and then in the engine control module, so the root fault should be fixed first.
Możliwe przyczyny
- Faulty CAN communication
- Internal fault in the gearbox control module (TCM)
Co możesz zrobić
- 1There is no specific fault-tracing for this code. Start in the transmission control module, since the root fault is stored there
- 2Fix the root fault, then erase the fault code in the transmission control module
- 3Erase the code in the engine control module only after the root fault code has been erased
- 4Check that the battery has a good charge and that the fuses are intact
- 5Look for breaks and chafing on the CAN wires between the engine control module and the transmission control module
- 6If the fault remains after these steps, have a workshop check the transmission control module with diagnostic equipment
Objawy, które możesz zauważyć1
- No noticeable symptoms for the driver
