Hva betyr feilkoden?
The Central Electronic Module (CEM) supplies power to the sensors for the parking assist. The fault is stored when the supply voltage is too low, which is caused by the supply wire being short-circuited to earth.
Mulige årsaker
- The supply wire is short-circuited to earth
Hva du kan gjøre
- 1Check that the fuses are intact
- 2Try the parking assist when reversing and see whether it gives a signal, then clear the fault code and road test
- 3Check the wiring to the parking sensors and the CEM for chafing and pinch damage
- 4With the connectors disconnected, use a multimeter to check that the supply wire has no contact with earth (the body)
- 5If the fault returns, have a workshop with diagnostic equipment check the parking sensors and the control module
Symptomer du kan merke1
- Parking assist at the front and rear does not work
Hva feilen kan påvirke3
- The function switches off during the driving cycle in which the fault is detected
- If the fault remains, the function is switched off permanently after 100 driving cycles where the fault was detected
- Erasing the fault codes and starting a new driving cycle resets the function
