  Refer to the intelligent tester operator's manual for further details.
5. Using the intelligent tester, perform zero point calibration of the yaw rate and acceleration sensor.
PERFORM ZERO POINT CALIBRATION OF YAW RATE AND ACCELERATION SENSOR (WHEN USING INTELLIGENT TESTER):
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. Check that the steering wheel is in the straight ahead position.
  3. Move the shift lever to the P position and apply the parking brake.
  4. Connect the intelligent tester to the DLC3.

  5. Turn the ignition switch to the ON position.
  6. Set the intelligent tester to test mode (select "TEST MODE").

    Refer to the intelligent tester operator's manual for further details.
2. Obtain the zero point of the yaw rate and acceleration sensor.
  1. Keep the vehicle in the stationary condition on a level surface for 2 seconds or more.
  2. Check that the ABS warning light and VSC warning light blink.

    HINT:
    - If the ABS warning light and VSC warning light do 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.
3. Turn the ignition switch off and disconnect the intelligent tester.
CLEAR ZERO POINT (WHEN USING SST CHECK WIRE)
1. Turn the ignition switch to the ON position.
2. Using SST, connect and disconnect terminals TS and CG of the DLC3 4 times or more within 8 seconds.

    - 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.
