Hva betyr feilkoden?
The PDM feeds the heating element that defrosts the exterior mirror. The module has detected that the current on the output is too high, which points to the signal cable to the mirror defroster being shorted to ground.
Mulige årsaker
- Signal cable to the mirror defroster is shorted to ground
- Moisture and/or oxidation in the connections
Hva du kan gjøre
- 1Read the code, clear it and activate the defogging to see whether the mirrors heat up and whether the code comes back
- 2Check the fuses in the fuse box; if a fuse has blown, look for a short to ground before a new fuse is fitted
- 3Check the connectors in the exterior mirror and at the door module for moisture, oxidation and loose contact
- 4Use a multimeter to check that the wire to the mirror defroster has no contact with ground (the body)
- 5If you have diagnostic equipment, activate the mirror defroster and check that it starts
- 6If the wire is intact but the code comes back: have a workshop check the mirror and the door module
Symptomer du kan merke1
- The defogging of the mirrors does not work
