Hva betyr feilkoden?
The engine control module (ECM) receives information about the desired engine speed from the transmission control module (TCM). If the TCM has registered a fault in the speed signal, it sends a fault message to the engine control module, which then stores the code. This is a follow-on fault: the root fault lies in the TCM and must be fixed first, and only then can the code be cleared.
Mulige årsaker
- The root fault lies in the transmission control module (TCM)
Hva du kan gjøre
- 1If you have a diagnostic tool, read the fault codes in the transmission control module (TCM) and fix those first
- 2Clear the fault code in the engine control module only after the root fault is fixed, then check that it does not return
- 3Have a workshop troubleshoot the transmission control module and the speed signal if the fault remains
Symptomer du kan merke1
- No noticeable symptoms for the driver
