1.CONNECTOR INSPECTION
1. Turn ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) connector.
3. Check terminal for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or replace terminal.
4. Reconnect connectors and then perform the self-diagnosis. See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Testing and Inspection/Scan Tool Testing and Procedures.
Is any item indicated on the self-diagnosis display?
YES - GO TO 2
NO - Poor connection of connector terminal. Repair or replace connector.
2.CHECK SOLENOID, VDC SWITCH-OVER VALVE AND ACTUATOR RELAY POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) connector.
3. Check voltage between ABS actuator and electric unit (control unit) connector E125 terminal 32 and ground.
Is the inspection result normal?
YES - GO TO 3
NO - Repair or replace malfunctioning components.
3.CHECK SOLENOID, VDC SWITCH-OVER VALVE AND ACTUATOR RELAY GROUND CIRCUIT
Check continuity between ABS actuator and electric unit (control unit) connector E125 terminals 16, 47 and ground.
Is the inspection result normal?
YES - Replace ABS actuator and electric unit (control unit). See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Hydraulic Control Assembly - Antilock Brakes/Service and Repair.
NO - Repair or replace malfunctioning components.

Special Repair Requirement
1.ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION
Always perform neutral position adjustment for the steering angle sensor when replacing the ABS actuator and electric unit (control unit). See:
Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Steering Angle Sensor/Testing and Inspection/Description.
- GO TO 2
2.CALIBRATION OF DECEL G SENSOR
Always perform calibration of decel G sensor when replacing the ABS actuator and electric unit (control unit). See: Brakes and Traction
Control/Antilock Brakes / Traction Control Systems/Yaw Rate Sensor/Testing and Inspection/Description.
