Was bedeutet der Fehlercode?
The tow hitch control module (TRM) has found that the brake light input signals for the trailer do not agree. One signal comes over a direct wire from the central electronic module (CEM), and the other over the CAN network. Normally nothing is noticed, but in extreme cases the trailer lighting can stop working.
Mögliche Ursachen
- Open circuit in the direct wire for the brake light signal
- Wire short-circuited to ground
- Contact resistance or oxidation in the connections
- Short circuit in the connections
- Open circuit in the CAN wire
Was Sie tun können
- 1Check the connectors to the tow hitch control module and to the left rear light for looseness, oxidation and contact resistance
- 2Use a multimeter to check that the brake light signal wire has no open circuit or contact with ground
- 3Remove any trailer connector from the socket before troubleshooting
- 4Have a workshop check the CAN wire and the central electronic module (CEM) if the fault remains
Symptome, die Sie bemerken können2
- Normally no symptoms are noticed
