Hva betyr feilkoden?
The tow hitch control module (TRM) has registered that the signal for the trailer parking lamps is too high in the wire to the trailer socket. This can be caused by the wire or the connectors to the socket being short-circuited to the power supply.
Mulige årsaker
- Short to the power supply in the signal wire or connectors between the tow hitch control module and the trailer socket
Hva du kan gjøre
- 1Remove any trailer connector from the socket before troubleshooting
- 2Use a multimeter to check that the wire between the tow hitch control module and the socket has no contact with battery voltage
