Was bedeutet der Fehlercode?
The CEM supplies power to the parking assist sensors. The fault is stored when the supply voltage is too high or missing, caused by an open circuit or a short circuit to battery voltage.
Mögliche Ursachen
- The supply wire has a break or is short-circuited to battery voltage
Was Sie tun können
- 1Check that the fuses are intact
- 2Check that the parking assist is switched on and see whether it gives any signal after the fault code has been cleared
- 3Check the supply wire to the sensors for breaks, chafing and loose connectors
- 4With the connectors disconnected, use a multimeter to check that the wire is continuous between the connector ends and has no contact with the battery positive
- 5If the fault remains, have a workshop with diagnostic equipment check the sensors and the supply from the CEM
Symptome, die Sie bemerken können1
- Parking assist at the front and rear does not work
Was der Fehler beeinflussen kann2
- The function switches off permanently after 100 driving cycles where the fault was detected
- Erasing the fault codes resets the output
