Was bedeutet der Fehlercode?
The fault code means no Hall pulses are registered from motor 4, which controls the seat height at the front edge, even though the motor is activated. Automatic operation of the seat and the outer mirrors then does not work, and neither does the automatic front seat memory adjustment.
Mögliche Ursachen
- Damaged Hall sensor in motor 4
- Signal cable short-circuited to supply voltage
Was Sie tun können
- 1Check that the seat fuses are intact.
- 2Look for corrosion on the connector to motor 4 and check that it is firmly seated.
- 3Use a multimeter to check that the signal wire from the Hall sensor has no contact with supply voltage.
- 4If you have a diagnostic tool: run motor 4 and see whether the Hall sensor value changes.
- 5If the fault remains, have a workshop check the motor and the control module.
Symptome, die Sie bemerken können2
- Automatic operation of the seat and outer mirrors does not work
