Theory Of Operation

The Brake System Control Module (BSCM) receives it's fused battery power and fused ignition feed input from the Power Distribution Center (PDC). These power inputs are used to power up the BSCM Supply, Pump, and Valves of the controller. The BSCM uses the chassis for its Ground. The BSCM continuously monitors these inputs for voltage and ground.
