Was bedeutet der Fehlercode?
The gear selector has an electrically controlled lock (shift-lock) that is meant to stop it being moved out of position P by accident. The lock should release when the brake is pressed. The fault means the control module has detected a signal to the lock that is too high, because the cable is short-circuited to voltage. The gear selector may then be hard or impossible to move.
Mögliche Ursachen
- Connector or cable is damaged
- Damaged gear selector module (GSM)
Was Sie tun können
- 1With the ignition on and the brake pedal pressed: try to move the gear selector out of P. If it still will not move, the fault is present
- 2Read off the fault code, clear it and check whether it comes back
- 3Check the cable to the lock for chafing and for connectors that may have touched a live wire; use a multimeter to check that the cable is not shorted to voltage
- 4Have a workshop check the connector at the transmission control module and the gear selector module; if no fault is found in the wiring, the gear selector module may need replacing
Symptome, die Sie bemerken können2
- Yellow warning symbol and text message in the display
- Gear selector hard or impossible to move
Was der Fehler beeinflussen kann1
- The gear selector cannot be moved out of position P
