Hva betyr feilkoden?
The integrated audio module (IAM) has found that the DC level on the wire coming from the AUX panel is too high. It shows up as the AUX panel working poorly or not at all.
Mulige årsaker
- The signal cable is short-circuited to the supply voltage
Hva du kan gjøre
- 1Read the code, clear it and test the AUX panel to see whether the fault comes back
- 2Check that the audio system fuses are intact; the location of each fuse is in the owner's manual or on the cover of the fuse box
- 3Check the connectors at the AUX panel and the audio module for loose or corroded contacts
- 4Look for chafing along the wire leading from the AUX panel and use a multimeter to check that it has no contact with the battery positive lead
- 5If the fault remains, have a workshop check the integrated audio module (IAM) and the AUX panel with diagnostic equipment
Symptomer du kan merke2
