Hva betyr feilkoden?
The transmission control module (TCM) can request higher engine speed before a downshift, and the request is sent to the engine control module over the CAN network. It is purely an information code showing that the engine control module has refused the requested speed increase, for example when the vehicle speed is too low.
Mulige årsaker
- The transmission control module (TCM) has requested higher engine speed before a downshift, and the engine control module has not allowed it
Hva du kan gjøre
- 1Because the code is informational it normally does not need remedying. Still check the gear shifts on a test drive
- 2If gear shifting quality is poor, have a workshop read the transmission control module (TCM)
Symptomer du kan merke1
- Gear shifting may feel poorer
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
