    Perform self-diagnosis for "ABS" again.

    Is DTC "C1109" detected? 

    YES: GO TO 3.

    NO: INSPECTION END

  3. CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) IGNITION POWER SUPPLY 
    1. Turn the ignition switch OFF.
    2. Disconnect ABS actuator and electric unit (control unit) harness connector.
    3. Check the voltage between ABS actuator and electric unit (control unit) harness connector and ground.
      ABS actuator and electric unit (control unit) - Voltage
      Connector Terminal
      E35 16 Ground Approx. 0 V
    4. Turn the ignition switch ON.
      CAUTION: Never start engine.

      ABS actuator and electric unit (control unit) - Continuity
      Connector Terminal
      E35 16 Ground Not existed

      Is the inspection result normal? 

      YES: Perform trouble diagnosis for ignition power supply. Refer to "WIRING DIAGRAM - IGNITION POWER SUPPLY - ".

      NO: Repair or replace error-detected parts.

  5. CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND CIRCUIT 
    1. Turn the ignition switch OFF.
    2. Check the continuity between ABS actuator and electric unit (control unit) harness connector and ground.
      ABS actuator and electric unit (control unit) - Continuity
      Connector Terminal
      E35 3 Ground Existed
      4

      Is the inspection result normal? 

      YES: GO TO 6.

      NO: Repair or replace error-detected parts.

  6. CHECK TERMINAL 
    • Check the ABS actuator and electric unit (control unit) pin terminals for damage or loose connection with harness connector.
    • Check the IPDM E/R pin terminals for damage or loose connection with harness connector.

      Is the inspection result normal? 

      YES: Replace ABS actuator and electric unit (control unit). Refer to "REMOVAL AND INSTALLATION ".
