Inspection Procedure

WARNING: This page is about a different car, the 2007 Nissan Quest. 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

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

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

    Yes: GO TO  3.

    No: GO TO 2.

  2. DATA MONITOR CHECK 

    Conduct "Data Monitor" of the "STR ANGLE SIG" to check if the status is normal.

    STEERING ANGLE SENSOR SPECIFICATIONS

    Steering condition Data monitor
    Straight-ahead -5° - + 5°
    Turn wheel 90° to the right. Approx. +90°
    Turn wheel 90° to the left. Approx. -90°

    OK or NG 

    OK: Inspection End.

    NG: GO TO 3.

  3. CONNECTOR INSPECTION 
    1. Disconnect the ABS actuator and electric unit (control unit) connector E125 and steering angle sensor M47.
    2. Check the terminals for deformation, disconnection, looseness or damage.

    OK or NG 

    OK: GO TO 4.

    NG: Repair or replace as necessary.

  4. CHECKING STEERING ANGLE SENSOR POWER AND GROUND 
    1. Turn the ignition switch ON.
    2. Check voltage between steering angle sensor connector M47 and ground.

    OK or NG 

    OK: Check the CAN communication system. Refer to "CAN COMMUNICATION SYSTEM INSPECTION ". If the CAN communication system is OK, replace spiral cable (steering angle sensor) and adjust neutral position of steering angle sensor. Refer to "ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION ".

    NG: Repair the circuit.
