Was bedeutet der Fehlercode?

Hall sensor 9 and hall sensor 13 report positions that do not agree with each other, which the roof control module does not accept. The fault can be caused by a damaged sensor or a sensor that has moved, but a protruding metal part that wrongly activates a sensor can also cause the code.

Mögliche Ursachen

Damaged hall sensor
A sensor has moved out of position
A sensor is wrongly activated by a protruding metal part

Was Sie tun können

1Read out and clear the fault code, test the roof and see whether the fault returns
2Make sure hall sensors 9 and 13 are firmly fitted, and that their connectors are clean, without oxidation or loose contacts
3Look for damage to the roof that could make both sensors activate at the same time
4If you have a diagnostic tool, follow both sensor states in live data while the roof runs and check that they do not show conflicting positions
5If a sensor is damaged, a workshop should replace it

Symptome, die Sie bemerken können1
