Signal missing

Checking the component
The infotainment module (ICM) has registered loss of communication with the integrated audio module (IAM).
If the malfunction is intermittent, it means that the malfunction has been registered at an earlier time but the malfunction no longer remains. Intermittent faults can be caused by interference upon start-up of the integrated audio module (IAM) or may be a different type of fault that can recur at different times. If the problem recurs, replace the integrated audio module (IAM).
In the case of a permanent fault, change the integrated audio module (IAM).
Remedy as necessary.
