Skid control ECU
  1. Housed in the brake actuator assembly.
  2. Processes the signals sent from each sensor to control the ABS.
ABS motor relay
  1. Supplies power to the pump motor.
  2. Housed in the skid control ECU.
ABS solenoid relay
  1. Supplies power to each solenoid.
  2. Housed in the skid control ECU.
