Signal missing

Checking the component
The infotainment module (ICM) has registered loss of communication with the Remote Digital Audio Receiver (RDAR).
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 remote digital audio receiver (RDAR) or may be a different type of fault that can recur at different times. If the fault recurs, replace the remote digital audio module (RDAR).
In the event of a permanent fault, replace the Remote Digital Audio Receiver (RDAR).
Remedy as necessary.
