Hva betyr feilkoden?
The reading at the MOST connector's transmitter diode on the subwoofer control module is too high. The control module has therefore become too hot, and it can switch off so that the subwoofer does not play.
Mulige årsaker
- High ambient temperature around the control module
- High power consumption in the control module
- Damaged subwoofer control module
Hva du kan gjøre
- 1Read out and clear the code, then check whether the bass speaker works again
- 2Check that the control module is not boxed in by items placed around it, so that air can circulate
- 3Check that the control module fuse is intact; the owner's manual shows where it is
- 4If the fault remains, have a workshop replace the subwoofer control module
Symptomer du kan merke2
- Other audio problems in the car's sound system
- No sound from the bass speaker
Hva feilen kan påvirke1
- The subwoofer control module is switched off
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
