Co oznacza ten kod błędu?
The Hall sensors in the rear door window lifts measure how fast each lift moves, which is used to know where the window is. The fault is stored when the signal from the sensor is too low for too long, because the supply wire has contact with ground, or because of moisture and oxidation in the connections. The automatic window operation for that window is then not available.
Możliwe przyczyny
- The supply wire is short-circuited to ground
- Moisture and/or oxidation in the connections
Co możesz zrobić
- 1Check that the fuses are intact
- 2Test the window up and down with the switch and check that 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 door for moisture, oxidation and chafing
- 5Read and clear the code, and check whether it returns
- 6If the fault remains, have a workshop with diagnostic equipment check the window lift and the control module
Objawy, które możesz zauważyć1
- The window lift does not work, works only partly or works incorrectly
Na co może wpływać usterka1
- Automatic up and down movement (AUTO-UP and AUTO-DOWN) of the window is blocked
