Co oznacza ten kod błędu?
The driver and passenger door modules read the Hall sensor in the rear door window lift, which measures how fast the window moves and therefore where it is. The fault is stored when the signal from the sensor is wrong while the window moves. This can be caused by a wire with contact to supply voltage or ground, a broken wire, a poor connection or a damaged sensor. Automatic window operation is then blocked.
Możliwe przyczyny
- The signal wire is short-circuited to supply voltage
- The signal wire is short-circuited to ground
- Open circuit in the signal wire
- Contact resistance, oxidation or a loose connection in the connectors
- Damaged Hall sensor
Co możesz zrobić
- 1Check that the fuses are intact
- 2Test the rear door window up and down with the switch and see whether it moves smoothly all the way
- 3If you have a diagnostic tool, follow the window position in live data while the window moves and check that the value changes smoothly
- 4Check the connector and the cable to the window lift in the rear door for moisture, oxidation and chafing
- 5Use a multimeter to check that the signal wire is not broken and has no contact with supply voltage or ground
- 6If the fault remains, have a workshop with diagnostic equipment check the Hall sensor and the control module
Objawy, które możesz zauważyć1
- The rear door window lift does not work, works only partly or works incorrectly
Na co może wpływać usterka1
- The control module blocks automatic window operation
