Was bedeutet der Fehlercode?

Although the fault is labelled an internal fault in the control module, it concerns the supply voltage to the sensors, and the code is set while that supply is switched on. The sensors are supplied in groups, so a short to ground in one group's supply can cause the fault. The roof may operate to a limited extent or not at all.

Mögliche Ursachen

The supply voltage to sensors 15, 16 and 19, or to sensors 3, 7, 9, 11, 12 and 13, is shorted to ground
The sensors are supplied in groups, and one group has a fault
Internal fault in the roof control module (CRM)

Was Sie tun können

1Read out and clear the fault code, test the roof and see whether it comes back
2Use a multimeter to confirm that the supply wires to the sensor group have no short to ground
3Look at the connectors to the sensors in the group for oxidation and loose connections
4Replace a faulty wire. If the fault remains, a workshop should look at the roof control module
