What does this fault code mean?
The parking assistance module (PAM) has registered that the voltage in the signal wire from parking sensor 5 is too low, or that the signal is missing altogether. The fault may be caused by a short to ground or by a break in the signal or supply wire, or in the connectors.
Possible causes
- Short-circuit to ground in the signal wire or the connectors between the PAM and parking sensor 5
- Open circuit in the signal wire or the connectors between the PAM and parking sensor 5
- Open circuit in the supply wire or the connectors between the PAM and parking sensor 5
What you can do
- 1Read and clear the code, then test drive the car to see whether it comes back
- 2Switch off the ignition and disconnect the connector to parking sensor 5, the outer sensor on the left front side
- 3Use a multimeter to check that the signal wire has no contact with ground and no break
- 4Check the supply wire to the sensor in the same way, for contact with ground and for a break
- 5Check that the connectors are intact, firmly seated and free from oxidation; replace the parking sensor only if the wiring is intact
