  3. READ VALUE USING GTS (STEERING ANGLE SIGNAL INFORMATION) 
    1. Check Data List item "steering angle signal information".

      Chassis > Steering Angle Sensor > Data List 

      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Steering Angle Signal Information Steering angle value (Rotation to the left side is positive) Min.: -3072.0 deg
      Max.: 3070.5 deg      		 Turning left: 0.0 to 3070.5 deg
      Turning right: -3072.0 to 0.0 deg      		 During steering operation: Changes in proportion with steering wheel rotation

    2. Save the steering angle signal information to the GTS memory.
      NOTE:
      • If the value is +/- 360 deg (+/-15 deg), the steering sensor was incorrectly installed by 1 rotation.
      • If the value is +/- 720 deg (+/-15 deg), the steering sensor was incorrectly installed by 2 rotations.
      • In situations other than the above, the steering sensor may have been incorrectly installed by 3 or more rotations.

        In this case, it is possible that the proper installation or removal procedures were not followed, and the steering sensor may have been damaged.

    See step  5

  5. PERFORM ZERO POINT CALIBRATION OF STEERING SENSOR 
    1. Disconnect cable from negative (-) auxiliary battery terminal.
    2. Connect cable to negative (-) auxiliary battery terminal.
    3. Drive the vehicle straight ahead at 35 km/h (22 mph) or more for at least 5 seconds.

      Result

      Proceed to
      NEXT

    Result: 

    NEXT 

    See step  6

  6. CHECK VEHICLE CONTROL HISTORY (RoB) 
    1. Based on the Freeze Frame Data and interview with the customer, attempt to reproduce the conditions when the malfunction occurred.
    2. Using the GTS, check for Vehicle Control History (RoB).

      *A Clockwise
      *B Counterclockwise
      *a Interlock
      NOTE:
      • Do not disconnect the steering sensor from the spiral cable.
      • Make sure that the cable is disconnected from the negative (-) auxiliary battery terminal.
    2. Based on the steering angle signal information that was saved to the GTS memory earlier, rotate the spiral cable with sensor sub-assembly.
      NOTE:
      • Rotate the steering sensor without disconnecting it from the spiral cable.
      • Make sure to follow the adjustment method shown in the table.
      • Failure to observe the following precautions may result in damage to the spiral cable with sensor sub-assembly.
        • When rotating the spiral cable with sensor sub-assembly, make sure to push on the interlock to release the interlock.
        • Do not turn the spiral cable with sensor sub-assembly using the airbag wire harness.
        • Do not forcibly rotate the part.
        • Make sure to perform the correct number of rotations in the correct direction.
      Steering Angle Signal Information Correction Method
      360 deg (+/-15 deg) Rotate clockwise (to the right), 1 rotation.
      -360 deg (+/-15 deg) Rotate counterclockwise (to the left), 1 rotation.
      720 deg (+/-15 deg) Rotate clockwise (to the right), 2 rotations.
