Hva betyr feilkoden?
The engine control module (ECM) monitors the speed signal that arrives over CAN. The code is set when the ECM gets a signal that data from the BCM or the TCM cannot be trusted, or when the speed signal over CAN is faulty. The fault therefore lies in the speed data from the BCM or the TCM.
Mulige årsaker
- The fault is in the brake control module (BCM)
- The fault is in the transmission control module (TCM)
Hva du kan gjøre
- 1Read the fault codes in the brake control module (BCM) and remedy them first.
- 2Read the fault codes in the transmission control module (TCM) and troubleshoot according to them.
- 3Check that the fuses are intact and that the connectors to the BCM and TCM are secure and clean.
- 4Do not work on the brake system yourself. Have a workshop check the BCM if the code returns.
