Inspection Procedure

WARNING: This page is about a different car, the 2008 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.
  1. SELF-DIAGNOSIS RESULT CHECK 

    Check self-diagnosis results.

    Self-diagnosis results

    YAW RATE SENSOR

    LONGITUDINAL G-SENSOR

    LATERAL G-SENSOR

    CAUTION: When on a turntable, such as at a parking structure entrance, or when on a moving object with the engine running, the VDC OFF indicator lamp might turn on and the self-diagnosis using the CONSULT-III the yaw rate sensor system might be displayed, but in this case there is no problem with the yaw rate sensor system. As soon as the vehicle leaves the turntable or moving object, restart the engine to return the system to normal.

    Is the above displayed in the self-diagnosis display items? 

    YES: GO TO 2.

    NO: Inspection End.

  2. CONNECTOR INSPECTION 

    Disconnect the ABS actuator and electric unit (control unit) connector E125 and yaw rate/side/decel G sensor connector M46.

    Check the terminals for deformation, disconnection, looseness or damage.

    OK or NG 

    OK: GO TO 3.

    NG: Repair or replace as necessary.

  3. YAW RATE/SIDE/DECEL G SENSOR HARNESS INSPECTION 
    1. Turn the ignition switch OFF.
    2. Check the continuity between the ABS actuator and electric unit (control unit) connector E125 and the yaw rate/side/decel G sensor connector M46.
      ABS ACTUATOR AND ELECTRIC UNIT SPECIFICATION

      ABS actuator and electric unit (control unit) connector E125 Yaw rate/side/decel G sensor connector M46 Continuity
      19 1 Continuity should exist.
      36 2
      35 3
      34 4
      4 5
      6 6

    OK or NG 

    OK: GO TO 4.

    NG: Repair or replace as necessary.

  4. YAW RATE/SIDE/DECEL G SENSOR INSPECTION 
    1. Connect the yaw rate/side/decel G sensor connector M46 and ABS actuator and electric unit (control unit) connector E125.
    2. Use "DATA MONITOR" to check the yaw rate/side/decel G sensor.
      YAW RATE/SIDE/DECEL G SENSOR SPECIFICATION

      Vehicle status YAW RATE SEN (Data monitor standard) SIDE G-SENSOR (Data monitor standard)
      When stopped -4 to +4 deg/s -1.1 to +1.1 m/s2
      Right hand turn Negative value Negative value
      Left turn Positive value Positive value

    OK or NG 

    OK: Inspection End.

    NG: Replace the yaw rate/side/decel G sensor. Refer to "REMOVAL AND INSTALLATION ".
