Dotyczy następujących modeli:

Co oznacza ten kod błędu?
The PDM feeds the heating element that defrosts the exterior mirror. The module has detected that the current on the output is too low, which points to the signal cable to the mirror defroster being shorted to voltage or having an open circuit.
Możliwe przyczyny
- Signal cable to the mirror defroster is shorted to voltage
- Open circuit on the signal cable
- Contact resistance, oxidation or poor contact in the connections
Co możesz zrobić
- 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 and make sure they are intact
- 3Check the connectors in the exterior mirror and at the door module for loose, oxidised or corroded contacts
- 4Use a multimeter to check that the signal cable to the defroster is intact, with no open circuit
- 5Use a multimeter to check that the wire has no voltage when the defroster is switched off, which would indicate a short to voltage
- 6If the wire is intact but the code comes back: have a workshop check the mirror and the door module
Objawy, które możesz zauważyć1
- The defogging of the mirrors does not work
