Intermittent Malfunction

HINT: The diagnostic trouble code status indicates that the brake control module (BCM) has previously registered a malfunction, but the malfunction is no longer active. 

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

Also check that the CAN-communication cables are not positioned too close to a source of interference, such as a cellular phone.

Remedy as necessary.
