Hva betyr feilkoden?
The head unit (IHU) monitors the signal wire to antenna amplifier 1, which serves the window antenna for AM/FM1. The code is stored when the voltage on the signal wire is too low, which points to a short-circuit to ground between the head unit and the amplifier.
Mulige årsaker
- The signal wire between the head unit and the amplifier is short-circuited to ground
Hva du kan gjøre
- 1Clear the code and check whether it returns
- 2Check that the fuses are intact
- 3Check that the wiring to the amplifier has no chafing or damage
- 4Use a multimeter to check that the signal wire is not short-circuited to ground
- 5If the fault remains, have a workshop check the amplifier and the wiring further
Symptomer du kan merke2
- Poor reception on the FM frequency
- Poor reception on the AM frequency
