Was bedeutet der Fehlercode?

The convertible roof module (CRM) cannot communicate correctly on the CAN network. The fault can be an open circuit or short in the network wiring, but it can also come from a fault in another control module on the same part of the network. The control module may switch itself off until its power supply has been broken.

Mögliche Ursachen

Short circuit between the CAN wires
Open circuit in one of the CAN wires
Internal fault in the roof control module (CRM)
Internal fault in another control module on the same part of the CAN network

Was Sie tun können

1Read out and clear the fault code and check whether it returns
2Check that the battery is charged and that the terminals are tight
3If you have a diagnostic tool, read the fault codes in the other control modules, since a fault in another module can disturb the communication
4The CAN network is measured at several points and needs parts disconnected, so if the fault remains a workshop with diagnostic equipment should examine the network

No or limited roof operation

Was der Fehler beeinflussen kann2
