Hva betyr feilkoden?
The parking assistance module (PAM) checks the supply voltage to the rear parking sensors. The code is stored when the DC voltage is too low, which means the supply wire is short-circuited to ground. If it is stored together with codes for individual parking sensors, fault tracing should start from it.
Mulige årsaker
- The power supply wire is short-circuited to ground
- Short-circuit in the connections
Hva du kan gjøre
- 1Check that the fuses for the parking assistance are intact; the fuse list in the car shows which one applies
- 2Read and clear the code, then test drive the car to see whether it comes back
- 3If you have a diagnostic tool, read the fault data for the supply to the rear sensors and see whether voltage is present when the ignition is on
- 4Use a multimeter to check that the supply wire to the rear sensors has no contact with ground
- 5Check the connectors in the supply circuit and that no chafing gives contact with ground
- 6If the wiring is intact, have a workshop trace the fault further
Symptomer du kan merke4
- The parking assistance does not work
- The information lamp is lit
- Message in the text display
