    ABS Control Unit

    Print

    The ABS control unit and Powertrain Control Module (PCM) manage the entire system via inputs from various sensors and programmed decisions which are stored within the unit. This management system includes the Vehicle Speed Sensor (VSS), pump motor, various electronic solenoids, ABS wheel sensors and an internal self-diagnostic mode. The main function of the ABS control unit is to perform calculations on the signals received from each one of the sensors at the wheels. This will enable it to control the system by actuating solenoid valves that regulate the flow and pressure of the brake fluid to each wheel. The system was designed with a sub-function that gives driving signals to the pump motor as well as signals the self diagnostic mode which is a necessity for backing up the anti-lock braking system.
