Was bedeutet der Fehlercode?
The power consumption of hall sensor 10 is lower than normal. When the hydraulic pump for the roof is activated, no sensor pulse appears, which points to the signal wire between the sensor and the control module being shorted to voltage. The roof may then not move as it should.
Mögliche Ursachen
- The signal wire between hall sensor 10 and the roof control module is shorted to voltage
- Damaged hall sensor
- Internal fault in the roof control module (CRM)
Was Sie tun können
- 1Read out and clear the fault code, test the roof in both directions and see whether the fault returns
- 2Check that the connector to hall sensor 10 is firmly fitted and clean
- 3With a multimeter you can check that the signal wire has no contact with voltage
- 4If no fault is found in the wire, hall sensor 10 may need replacing by a workshop
- 5If the fault remains, a workshop needs to check the roof control module
