Co oznacza ten kod błędu?
The integrated audio module (IAM) monitors the signal from the microphone and has received no signal at all. The microphone therefore does not work. The cause is a break in the signal wire or a damaged microphone.
Możliwe przyczyny
- Open circuit on the signal wire between the module and the microphone
- Damaged microphone
Co możesz zrobić
- 1With the ignition off, disconnect the microphone connector and check the connectors for contact resistance, play and oxidation
- 2Follow the wire between the microphone and the module and look for breaks, chafing or loose joints
- 3Use a multimeter to check that the signal wire is not broken
- 4If no fault is found in the wire, have a workshop replace the microphone
- 5After the work, check that the microphone works and that the fault code does not come back
