Hva betyr feilkoden?
The subwoofer has two speaker elements, SUB 1 and SUB 2, each driven by its own channel. The audio control module (AUD) has registered too high a signal on the wiring to element SUB 1, usually because that wire is shorted to supply voltage. The code is set while the module is active, and bass from that element is lost.
Mulige årsaker
- Short circuit to supply voltage in the wiring from element SUB 1 to the audio module
Hva du kan gjøre
- 1Check that the audio system fuses are intact and see where they are located in the owner's manual
- 2Check the connectors at the subwoofer and at the audio module for contact resistance, play and oxidation
- 3Look for chafing and places where the wire could have touched a live circuit
- 4Read the signal to element SUB 1 with diagnostic equipment and repair the short to supply voltage
Symptomer du kan merke2
- No sound from the subwoofer
- Front and rear parking assistance does not work
