Was bedeutet der Fehlercode?

Hall sensor 18 and hall sensor 5 have positions that do not agree with each other, and the roof control module reacts to this. The cause can be a damaged sensor, a sensor that has been displaced, or a protruding metal part wrongly activating a sensor. The roof may then operate to a limited extent or not at all.

Mögliche Ursachen

Damaged hall sensor
A sensor has been displaced
A protruding metal part wrongly activates a sensor

Was Sie tun können

1Clear the fault code and test the roof in both directions to see whether it returns
2Make sure hall sensors 5 and 18 are fixed in place and their connectors are clean, without oxidation or play
3Go over the parts of the roof and look for damage that could affect where the sensors sit
4If you have a diagnostic tool, follow the sensor positions in live data while the roof moves
5If the fault remains after these checks, a workshop should inspect and if needed replace the sensor

Symptome, die Sie bemerken können1
