Hva betyr feilkoden?
Hall sensor 18 draws less current than normal, and when the hydraulic pump for the roof is activated there is no sensor pulse. The cause may be the signal wire from the sensor to the roof control module being shorted to voltage. The roof may then not move as it should.
Mulige årsaker
- The signal wire between hall sensor 18 and the roof control module is shorted to voltage
- Damaged hall sensor
- Internal fault in the roof control module (CRM)
Hva du kan gjøre
- 1Read out and clear the fault code, test the roof in both directions and see whether the fault returns
- 2Check that the connector at hall sensor 18 is fully seated and free from oxidation
- 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 18 may be damaged and need replacing by a workshop
- 5If the fault remains, a workshop needs to check the roof control module
Symptomer du kan merke2
- The roof cannot be operated, or only partly
