Inspection Procedure

WARNING: This page is about a different car, the 2005 Nissan Titan. 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 RESULTS CHART

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

    Is above displayed in self-diagnosis item?

    1. YES: GO TO  2.
    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?

    1. YES: GO TO  3.
    2. NO: Inspection End.
  3. CHECK STEERING ANGLE SENSOR HARNESS 
    1. Check CAN communication system. Refer to CAN COMMUNICATION .
    2. Turn ignition switch OFF and disconnect steering angle sensor connector M47 and 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.

  4. 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 REFERENCE CHART

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

    OK or NG

    1. OK: Perform ABS actuator and electric unit (control unit) self-diagnosis again.
    2. NG: Replace spiral cable (steering angle sensor) and adjust neutral position of steering angle sensor. Refer to ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION .
