Checking The Component

The infotainment control module (ICM) has registered that there is no communication with the subwoofer module (SUB).

If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults may occur at start up of the subwoofer module (SUB), or may be a different type of fault that occurs on different occasions. The fault is evaluated depending on how it occurs.

Replace the subwoofer module (SUB) in the event of a permanent fault.

Remedy as necessary.
