Hva betyr feilkoden?
The engine control module (ECM) receives a request from the transmission control module (TCM) over the CAN network for a higher engine speed to ease downshifting. If the request lies outside the permitted limits or is otherwise faulty, the fault code is stored. The fault appears when downshifting while driving.
Mulige årsaker
- Fault in the transmission control module (TCM)
Hva du kan gjøre
- 1Read the fault code, clear it and test drive the car with a few downshifts to see whether it returns
- 2First check whether there are fault codes in the transmission control module; these should be traced before the engine control module
- 3If you have a diagnostic tool: read the engine speed request from the transmission in live data during a downshift and see whether the value is reasonable
- 4Have a workshop with diagnostic equipment check the transmission control module and the communication on the CAN network
Symptomer du kan merke1
- No noticeable symptoms for the driver
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
