Replacing The Component

The Subwoofer module (SUB) has registered an internal fault.

If the fault is intermittent it means that it has been registered previously but is no longer present. Intermittent faults can occur for a number of different reasons. The fault is evaluated depending on how it occurs. If the fault recurs, replace the Subwoofer module (SUB).

In the event of a permanent fault, replace the Subwoofer module (SUB). See SUBWOOFER MODULE (SUB), REPLACING .

Remedy as necessary.
