Was bedeutet der Fehlercode?

The transmission control module (TCM) does not get a valid signal for the requested engine braking from the engine control module over the CAN network. The signal decides when engine braking should be activated, for example in first gear. Troubleshooting should be carried out in the engine control module or on the CAN link to it.

Mögliche Ursachen

The cause should be looked for in the engine control module (ECM)
Temporary breaks or a short on the CAN wire between the ECM and the TCM

Was Sie tun können

1First read the codes in the central electronics control module (CEM) and in the engine control module, and deal with them
2Do not clear this code until the engine control module fault is fixed and its code cleared
3If no codes are stored, have a workshop troubleshoot the CAN network

Symptome, die Sie bemerken können1

Engine braking is absent, reduced or works incorrectly

Was der Fehler beeinflussen kann1

The transmission control module uses a default value for the signal
