Hva betyr feilkoden?
The audio control module (AUD) measures the DC voltage on the outputs to the right rear door speaker. If the difference between the outputs becomes too large, the code is set. The fault most often lies in the module, but a short to supply voltage or to ground in the wiring can give the same symptoms.
Mulige årsaker
- Damaged audio control module
- Short circuit to supply voltage
- Short circuit to ground
Hva du kan gjøre
- 1Check whether similar codes are stored for the other speakers, since a shared fault is then likely
- 2Check the connectors at the module and the speaker for contact resistance, play and oxidation
- 3Visually inspect the wiring between the module and the speaker and replace it if damaged
- 4Check the module and the speaker with diagnostic equipment and replace the faulty part
Symptomer du kan merke2
- No sound from the right rear door speaker
- Front and rear parking assistance does not work
