Was bedeutet der Fehlercode?

The engine control module monitors its link with the transmission control module (TCM). The code is set when the TCM requests that the malfunction indicator lamp be lit, which is treated as a faulty signal, and also when that signal cannot be seen on the CAN network. The fault therefore most likely lies with the TCM.

Mögliche Ursachen

A fault in the transmission control module (TCM)
The signal from the transmission control module is missing from the CAN network

Was Sie tun können

1Read the TCM fault codes first, then the CEM codes
2Remedy the TCM faults and the CAN-related codes in the CEM first; clear this code once they are gone
3Check that the connectors to the transmission control module are fully seated and free from oxidation
4After the repair, road test the car and see whether the malfunction indicator lamp comes on again
