Vehicle Stability Control System: Calibration

  1. DESCRIPTION 
    • After replacing the VSC relevant components or performing "Front wheel alignment adjustment", clear and read the sensor calibration data.
    • Follow the chart to perform calibration.

      OPERATION CHART

      Replacing Parts / Operation Necessary Operation
      ABS & TRACTION Actuator Assembly (Skid Control ECU) Yaw rate sensor and acceleration sensor zero point calibration.
      Yaw Rate Sensor (Acceleration Sensor)
      1. Clearing zero point calibration data.
      2. Yaw rate and acceleration sensor zero point calibration.
      Front Wheel Alignment Adjustment
      1. Clearing zero point calibration data.
      2. Yaw rate and acceleration sensor zero point calibration.
  2. CLEAR ZERO POINT CALIBRATION (WHEN USING TECHSTREAM:) 
    1. Connect Telecaster to the DLC3.
    2. Turn the ignition switch on (IG).
    3. Operate Telecaster to erase the codes (select "RESET MEMORY").

      HINT:

      Refer to Telecaster operator's manual for further details.

    4. Using Telecaster, perform zero point calibration of the yaw rate and acceleration sensor.
  3. PERFORM ZERO POINT CALIBRATION OF YAW RATE SENSOR AND ACCELERATION SENSOR (WHEN USING TECHSTREAM:) 
    NOTE:
    • While obtaining the zero point, do not vibrate the vehicle by tilting, moving or shaking it and keep it in a stationary condition. (Do not start the engine.)
    • Be sure to do this on a level surface (with an inclination of less than 1 degree).
    1. Procedures for test mode.
      1. Check that the steering wheel is in the straight-ahead position and move the shift lever to the P position.
        NOTE: DTC C1210/36 and C1336/39 will be recorded if the shift lever is not in the P position (See DTC C1210/36 ZERO POINT CALIBRATION OF YAW RATE SENSOR UNDONE; DTC C1336/39 ZERO POINT CALIBRATION OF ACCELERATION SENSOR UNDONE  ).
      2. Connect Telecaster to the DLC3.
      3. Turn the ignition switch on (IG).
      4. Set Telecaster to test mode (select "TEST MODE").

        HINT:

        Refer to Telecaster operator's manual for further details.

    2. Obtain the zero point of the yaw rate sensor and acceleration sensor.
      1. Keep the vehicle in the stationary condition on a level surface for 2 seconds or more.
      2. Check that the VSC warning light is blinking in TEST MODE.

        HINT:

        • If the VSC warning light does not blink, perform zero point calibration again.
        • The zero point calibration is performed only once after the system enters the test mode.
        • Calibration cannot be performed again until the stored data is cleared once.
    3. Turn the ignition switch off and disconnect Telecaster.

  4. CLEAR ZERO POINT CALIBRATION 
    1. Turn the ignition switch on (IG).
    2. Using SST, connect and disconnect terminals TS and CG of the DLC4 times or more within 8 seconds.

    3. Check that the VSC warning light indicates the normal system code.
    4. Remove the SST from the terminals of the DLC3.
    5. Using a check wire, perform zero point calibration of the yaw rate and acceleration sensor.
  5. PERFORM ZERO POINT CALIBRATION OF YAW RATE SENSOR AND ACCELERATION SENSOR 
    NOTE:
    • While obtaining the zero point, do not vibrate the vehicle by tilting, moving or shaking it and keep it in a stationary condition. (Do not start the engine.)
    • Be sure to do this on a level surface (with an inclination of less than 1 degree).

    1. Procedures for test mode.
      1. Turn the ignition switch off.
      2. Using SST, connect and terminals TS and CG of the DLC3.

      3. Check that the steering wheel is in the straight-ahead position and move the shift lever to the P position.
        NOTE: DTC C1210/36 and C1336/39 will be recorded if the shift lever is not in the P position (See DTC C1210/36 ZERO POINT CALIBRATION OF YAW RATE SENSOR UNDONE; DTC C1336/39 ZERO POINT CALIBRATION OF ACCELERATION SENSOR UNDONE  ).

    2. Obtain the zero point of the yaw rate sensor and acceleration sensor.
      1. Turn the ignition switch on (IG).
      2. Keep the vehicle in the stationary condition on a level surface for 2 seconds or more.
      3. Check that the VSC warning light is blinking in TEST MODE.

        HINT:

        • If the VSC warning light does not blink, perform zero point calibration again.
        • The zero point calibration is performed only once after the system enters the test mode.
        • Calibration cannot be performed again until the stored data is cleared once.
    3. Turn the ignition switch off and disconnect the SST from the DLC3.
