Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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 for the brake control module and the central electronic module. Check 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.
