Co oznacza ten kod błędu?
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.
Możliwe przyczyny
- Damaged Hall sensor in motor 4
- Signal cable short-circuited to ground
- Broken wire on the signal line running to the Hall sensor
Co możesz zrobić
- 1Check that the seat fuses are intact.
- 2Look at the connector to motor 4, check that it is firmly seated and look for chafed wiring.
- 3Use a multimeter to check that the signal wire to the Hall sensor is not short-circuited to ground and has no open circuit.
- 4If you have a diagnostic tool: run motor 4 and see whether the Hall sensor value changes in live data.
- 5If the fault remains, have a workshop check the motor and the control module.
Objawy, które możesz zauważyć2
