Checking Wiring And Terminals

Check the connector to the brake control module (BCM). Check for damaged or bent pins as well as contact resistance and oxidation.

Check the cable between Brake control module (BCM)terminal #11 (#A11) and Differential electronic module (DEM) terminal #7. Check for an open-circuit and short-circuit to ground or voltage.

Check the cable between Brake control module (BCM)terminal #15 (#A15) and Differential electronic module (DEM) terminal #8. Check for an open-circuit and short-circuit to ground or voltage.

Check that the wiring is not too close to a source of interference such as a carphone etc.

Remedy as necessary.
