Co oznacza ten kod błędu?
The integrated audio module (IAM) has detected that the signal from the microphone is too high on the signal cable. It most often shows up as the microphone not working and the other party not hearing you during a hands-free call.
Możliwe przyczyny
- Short circuit to supply voltage on the signal cable between the audio module and the microphone
Co możesz zrobić
- 1Read the code, clear it and make a test call on hands-free to see whether the fault comes back
- 2Check that the fuses for the audio system and phone 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 microphone and the audio module for loose or corroded contacts
- 4Look for chafing on the signal cables and use a multimeter to check that they have no contact with the battery positive lead
- 5If the fault remains, have a workshop check the integrated audio module (IAM) and the microphone with diagnostic equipment
