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.

    COMPONENTS OPERATION CHART

    Replacing Parts / Operation Necessary Operation
    Skid control ECU Yaw rate and acceleration sensor zero point calibration.
    Yaw rate and 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. OBTAIN ZERO POINT OF YAW RATE AND ACCELERATION SENSOR (TECHSTREAM) 
    NOTE:
    • While obtaining the zero point, keep the vehicle stationary and do not vibrate, tilt, move, or shake it. (Do not start the engine.)
    • Be sure to perform this procedure on a level surface (with an inclination of less than 1 degree).
    1. Clear the zero point calibration data.
      1. Turn the engine switch off.
      2. Connect Techstream to the DLC3.
      3. Check that the steering wheel is centered and move the shift lever to the P position.
      4. Turn the engine switch on (IG).
      5. Operate Techstream to erase the codes (select "Reset Memory").

        HINT:

        Refer to Techstream operator's manual for further details.

      6. Turn the engine switch off.
        NOTE: If the engine switch is turned on (IG) for more than 15 seconds with the shift lever in the P position after zero point of the yaw rate and acceleration sensor has been cleared, only the zero point of the yaw rate sensor will be stored. If the vehicle is driven under these conditions, the skid control ECU will store the zero point calibration for the acceleration sensor as not being completed. The skid control ECU will then also indicate this as a malfunction of the VSC system using the multi information display.
    2. Perform zero point calibration of the yaw rate and acceleration sensor.
      1. Turn the engine switch off.
      2. Check that the steering wheel is centered and move the shift lever to the P position.
        NOTE: DTCs 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  ).
      3. Connect Techstream to the DLC3.
      4. Turn the engine switch on (IG).
      5. Set Techstream to Test Mode (select "Test Mode").

        HINT:

        Refer to Techstream operator's manual for further details.

      6. After the Test Mode has been entered, keep the vehicle stationary on a level surface for 2 seconds or more.
      7. Check that the VSC test mode message is displayed on the multi information display (Test Mode).

        HINT:

        • The SLIP indicator light remains on during Test Mode because TRAC is prohibited.
        • If the VSC test mode message is not displayed on the multi information display, perform zero point calibration again.
        • Illustrations may differ from the actual screen displayed depending on the specifications of the vehicle and customized settings.
        • 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.

      8. Turn the engine switch off and disconnect Techstream.
  3. OBTAIN ZERO POINT OF YAW RATE AND ACCELERATION SENSOR (SST CHECK WIRE) 
    NOTE:
    • While obtaining the zero point, keep the vehicle stationary and do not vibrate, tilt, move, or shake it. (Do not start the engine.)
    • Be sure to perform this procedure on a level surface (with an inclination of less than 1 degree).
    1. Clear the zero point calibration data.
      1. Turn the engine switch off.
      2. Check that the steering wheel is centered and move the shift lever to the P position.
      3. Turn the engine switch on (IG).
      4. The warning light and indicator light come on for 3 seconds to indicate that the initial check is completed.
      5. Using SST, connect and disconnect terminals TS and CG of the DLC3 4 times or more within 8 seconds.

      6. Check that the check VSC message is displayed on the multi information display.
        NOTE: If the engine switch is turned on (IG) for more than 15 seconds with the shift lever in the P position after zero point of the yaw rate and acceleration sensor has been cleared, only the zero point of the yaw rate sensor will be stored. If the vehicle is driven under these conditions, the skid control ECU will store the zero point calibration for the acceleration sensor as not being completed. The skid control ECU will then also indicate this as a malfunction of the VSC system using the multi information display.

    2. Perform zero point calibration of the yaw rate and acceleration sensor.
      1. Turn the engine switch off.
      2. Check that the steering wheel is centered and move the shift lever to the P position.
        NOTE: DTCs 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  ).
      3. Using SST, connect terminals TS and CG of the DLC3.
