Hva betyr feilkoden?
The fault code means no Hall pulses are registered from motor 2, which controls the backrest rake, 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.
Mulige årsaker
- Damaged Hall sensor in motor 2
- Signal cable short-circuited to supply voltage
Hva du kan gjøre
- 1Check that the seat fuses are intact.
- 2Check that the connector to motor 2 is firmly seated and not corroded.
- 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 2 and check that the Hall sensor value changes.
- 5If the fault remains, have a workshop check the motor with its Hall sensor and the control module.
Symptomer du kan merke2
- Automatic operation of the seat and outer mirrors does not work
- The automatic memory adjustment of the front seat is not working
