Co oznacza ten kod błędu?
The audio control module (AUD) measures the DC voltage on the two outputs to the front left door speaker. If the difference between them becomes too large, the code is set and sound from the speaker may be lost. The fault most often lies in the module itself, but a short to supply voltage or to ground in the wiring can give the same symptoms.
Możliwe przyczyny
- Damaged audio control module
- Short circuit to supply voltage in the wiring to the speaker
- Short circuit to ground in the wiring to the speaker
Co możesz zrobić
- 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
Objawy, które możesz zauważyć2
