Intermittent fault

HINT: The status of the diagnostic trouble code (DTC) indicates that the brake control module has previously registered a fault but that the fault is not active. 

Check the connectors of the brake control module (BCM) and the differential electronic module (DEM) for contact resistance and oxidation.

Also check that the wiring for CAN communication is not too close to a source of interference such as a carphone etc.

Remedy as necessary.
