Decel G sensor calibration

CAUTION: Always use CONSULT-III for the decel G sensor calibration. (It cannot be adjusted other than with CONSULT-III.)
NOTE: Yaw rate/side/decel G sensor calibration is performed when performing the decel G sensor calibration.
  1. CHECK THE VEHICLE STATUS
    1. Steer the steering wheel to the straight-ahead position. Stop the vehicle on level surface.
    2. Stop the engine.
    3. Turn the ignition switch OFF.

      Is the vehicle stopped in the straight-ahead position on level surface? 

      YES: Go to 2.

      NO: Steer the steering wheel to the straight-ahead position. Stop the vehicle on level surface.

  2. PERFORM DECEL G SENSOR CALIBRATION
    CAUTION:
    • Never allow passenger or load on the vehicle.
    • Never apply vibration to the vehicle body when opening or closing door during calibration.

    With CONSULT-III.

    1. Turn the ignition switch ON.
      CAUTION: Never start engine.
    2. Select "ABS", "WORK SUPPORT", "DECEL G SENSOR CALIBRATION" in this order.
    3. Select "START".
    4. After approx. 10 seconds, select "END".
    5. Turn ignition switch OFF and then turn it ON again.
      CAUTION: Be sure to perform the operation above.

    2. Select "ABS", "DATA MONITOR", "ECU INPUT SIGNALS" and "DECEL G SENSOR" in this order. Check that the signal is within the specified value.

      DECEL G SENSOR : Approx. 0 m/s 2 

      Is the inspection result normal? 

      YES: Go to 4.

      NO: Go to  1.

  4. ERASE SELF-DIAGNOSIS MEMORY

    Erase Self-diagnosis result of "ABS".

    Are the memories erased? 

    YES: Go to 5.

    NO: Check the items indicated by the self-diagnosis.

  5. PERFORM DECEL G SENSOR CALIBRATION (TRANSMISSION)

    Perform decel G sensor calibration. Refer to "SPECIAL REPAIR REQUIREMENT ".
