Hva betyr feilkoden?

The CEM has no contact with the parking assistance module (PAM), so the park assist does not work. The fault most often lies in the supply to the PAM, its earth or the connector at the module. It can also be a break in the LS-CAN wiring.

Mulige årsaker

No supply to the PAM
Open circuit in the earth wire to the PAM
Contact resistance in the connections
Open circuit in the LS-CAN wires to the PAM
The PAM does not suit the car, for example a used module with other software or hardware

Hva du kan gjøre

1Engage reverse and release the handbrake. If the park assist text does not appear in the display, the fault is probably in the PAM or its supply
2Check the PAM fuse in the CEM. If it has blown, check the circuit after it for a short to earth before replacing it
3Use a multimeter to check that the supply wire from the CEM to the PAM has no break and is not shorted to earth
4Check the PAM earth point for contact resistance and oxidation, and that the wire to it is not broken
5With a diagnostic tool, read the PAM ID. If it reads, the communication is probably fine and the fault may be intermittent
6Check the supply first before replacing any part, since that is where the fault most often lies
