Inspection Procedure

  1. CHECK SELF-DIAGNOSIS RESULTS 

    Check self-diagnosis results.

    SELF-DIAGNOSIS RESULTS

    Self-diagnosis results
    YAW RATE SENSOR
    SIDE G-SEN CIRCUIT

    Is above displayed on the self-diagnosis display? 

    YES: GO TO 2.

    No: INSPECTION END

  2. CHECK CONNECTOR 
    1. Turn ignition switch OFF and disconnect yaw rate/side G sensor connector M145 and ABS actuator and electric unit (control unit) connector E30, check terminal for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or replace terminal.
    2. Reconnect connector and perform self-diagnosis.

    OK or NG 

    OK: INSPECTION END

    NG: GO TO 3.

  3. CHECK YAW RATE/SIDE G SENSOR POWER SUPPLY CIRCUIT 
    1. Turn ignition switch OFF and disconnect yaw rate/side G sensor connector M145.
    2. Turn ignition switch ON or OFF and check voltage between yaw rate/side G sensor harness connector M145 terminal 3 and ground.
      VOLTAGE SPECIFICATION

      Yaw rate/side G sensor Ground Condition Voltage
      3 - Ignition switch ON Battery voltage (Approx. 12 V)
      Ignition switch OFF Approx. 0 V

      G05211857

    OK or NG 

    OK: GO TO 4.

    NG:

    • Repair or replace malfunctioning components.
    • Perform the self-diagnosis, and make sure that the result shows "NO DTC IS DETECTED".
  4. CHECK YAW RATE/SIDE G SENSOR HARNESS 
    1. Turn ignition switch OFF and disconnect Yaw rate/side G sensor connector M145 and ABS actuator and electric unit (control unit) connector E30.
    2. Check continuity between Yaw rate/side G sensor harness connector M145 and ABS actuator and electric unit (control unit) harness connector E30.

      G05211858
      CONTINUITY SPECIFICATION

      ABS actuator and electric unit (control unit) Yaw rate/side G sensor Continuity
      18 1 Yes
      37 2
      16 4
      20 5
      15 6

    OK or NG 

    OK: GO TO 5.

    NG:

    • Repair or replace malfunctioning components.
    • Perform the self-diagnosis, and make sure that the result shows "NO DTC IS DETECTED".
  5. CHECK DATA MONITOR 
    1. Connect the Yaw rate/side G sensor connector and ABS actuator and electric unit (control unit) connector.
    2. Select "YAW RATE SEN", "SIDE G-SENSOR" in "DATA MONITOR" and check Yaw rate/side G sensor signal.
      YAW RATE SEN (DATA MONITOR)

      Vehicle condition YAW RATE SEN (DATA MONITOR) SIDE G-SENSOR (DATA MONITOR)
      Stopped Approx. 0 d/s Approx. 0 m/s2
      Turning right Negative value Negative value
      Turning left Positive value Positive value

    OK or NG 

    OK:

    • Replace ABS actuator and electric unit (control unit).
    • Perform the self-diagnosis, and make sure that the result shows "NO DTC IS DETECTED".

    NG:

    • Replace Yaw rate/side G sensor.
    • Perform the self-diagnosis, and make sure that the result shows "NO DTC IS DETECTED".
