Hva betyr feilkoden?
The central electronic module (CEM) has lost communication with the transmission control module (TCM) and sets this code. The fault lies in the communication, not in the CEM, so the CEM should not be replaced. Without contact with the TCM, gear changes may not happen and a substitute gear is engaged.
Mulige årsaker
- The TCM is not getting power
- The ground wire to the TCM is broken
- Contact resistance in the connections
- Broken CAN wiring to the TCM
- Wrong TCM for this car, for example a used module with different software or hardware
Hva du kan gjøre
- 1Check the TCM fuse. If it has blown, replace it once. If it blows again, use a multimeter to check the wire after it has no contact with ground.
- 2Check that the connectors to the transmission control module are seated and free of corrosion, chafing or damage
- 3Check that the ground wire to the transmission control module is tight and clean. Use a multimeter to check it has no break
- 4If the fault remains, read the module ID with a diagnostic tool
- 5After the work, clear the code and drive the car to check that gear changes work
Symptomer du kan merke3
- Gear changes do not happen
- The malfunction indicator lamp (MIL) is lit
- A message appears in the display
Hva feilen kan påvirke1
- A substitute gear is engaged
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
