Inspection Procedure

WARNING: This page is about a different car, the 2005 Nissan Frontier. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK SELF-DIAGNOSIS RESULT 

    Check self-diagnosis results.

    SELF-DIAGNOSIS RESULT

    Self-diagnosis results
    ST ANGLE SEN CIRCUIT
    ST ANG SEN COM CIR

    Is above displayed in self-diagnosis item? 

    • YES: GO TO 2.
    • NO: Inspection End.
  2. CHECK CONNECTOR 
    1. Disconnect steering angle sensor connector M47 and ABS actuator and electric unit (control unit) connector E125 and check terminals for deformation, disconnection, looseness, or damage. Repair or replace as necessary.
    2. Reconnect connectors and repeat ABS actuator and electric unit (control unit) self-diagnosis.

    Is "ST ANGLE SEN CIRCUIT" or "ST ANG SEN COM CIR" displayed? 

    • YES: GO TO 3.
    • NO: Inspection End.
  3. CHECKING STEERING ANGLE SENSOR POWER AND GROUND 
    1. Check voltage between steering angle sensor harness connector M47 and body ground.

  4. CHECK STEERING ANGLE SENSOR HARNESS 
    1. Check CAN communication system. Refer to "CAN COMMUNICATION ".
    2. Disconnect ABS actuator and electric unit (control unit) connector E125.
    3. Check continuity between ABS actuator and electric unit (control unit) connector E125 and steering angle sensor connector M47.

  5. CHECK STEERING WHEEL PLAY 

    Check steering wheel play. Refer to "CHECKING STEERING WHEEL PLAY ".

    OK or NG 

    • OK: GO TO 6.
    • NG: Adjust steering wheel play.
  6. CHECK DATA MONITOR 
    1. Connect steering angle sensor and ABS actuator and electric unit (control unit) connectors.
    2. Use "DATA MONITOR" to check if the status of "STR ANGLE SIG" is normal.
      DATA MONITOR SPECIFICATION

      Steering condition Data monitor
      Straight-ahead -3.5 deg to +3.5 de
      Turn wheel to the right by 90° Approx. - 90deg
      Turn wheel to the left by 90° Approx. + 90deg

    OK or NG
