    Actuator



    Solenoid
    Removal & Installation

    The actuator contains the solenoid control valves, pump and motor, reservoirs for temporary collection of brake fluid released from the lines as well as check and relief valves. The actuator is located at the right front of the engine compartment.

    The relays and solenoids are controlled by the ECU. Under normal braking conditions, the solenoids are in the open or pressure-build position, allowing brake fluid to pass proportional to pedal pressure. During anti-lock function, the solenoids are commanded into positions to either hold or release brake fluid line pressures as required. When anti-lock function is no longer needed, the solenoids reset to the normal position. Additionally, if the ECU detects a system fault, the solenoids are immediately set to the normal or default position.
