Was bedeutet der Fehlercode?
The rear door window lifts have Hall sensors that measure how fast each window motor rotates, and this is how the window position is determined. The module has detected that the signal from one of the sensors is incorrect.
Mögliche Ursachen
- Signal cable is shorted to voltage
- Signal cable is shorted to ground
- Open circuit on the signal cable
- Contact resistance, oxidation or poor contact in the connections
- Damaged Hall sensor
Was Sie tun können
- 1Read the code, clear it and run the window up and down to see whether the code comes back
- 2Check the fuses for the window lifts in the fuse box and make sure they are intact
- 3Check the connectors at the window lift motor in the rear door and at the door module for moisture, oxidation and loose contact
- 4Use a multimeter to check that the signal cable from the sensor has no contact with ground (the body) or voltage, and that it has no open circuit
- 5If you have diagnostic equipment, read the window position in live data while you run the window up and down and check that the value changes smoothly
- 6If the wiring is intact but the fault remains: have a workshop check the Hall sensor and the control module
Symptome, die Sie bemerken können1
- The electric window does not work, works with reduced function or works incorrectly
Was der Fehler beeinflussen kann1
- The control module blocks automatic window operation
