Hva betyr feilkoden?
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.
Mulige årsaker
- The supply wire has a break or is short-circuited to battery voltage
Hva du kan gjøre
- 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
Symptomer du kan merke1
- Parking assist at the front and rear does not work
Hva feilen kan påvirke2
- The function switches off permanently after 100 driving cycles where the fault was detected
- Erasing the fault codes resets the output
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
