2. CLEAR ZERO POINT CALIBRATION (WHEN USING INTELLIGENT TESTER:)

(a) Connect the intelligent tester to the DLC3.

(b) Turn the ignition switch on (IG).

(c) Operate the intelligent tester to erase the codes (select "RESET MEMORY").

HINT:

Refer to the intelligent tester operator's manual for further details.

(d) Using the intelligent tester, 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 INTELLIGENT TESTER:) NOTICE:

• 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).

(a) 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.

NOTICE:

DTC C1210/36 and C1336/39 will be recorded if the shift lever is not in the P position (See page BC-165).

(2) Connect the intelligent tester to the DLC3.

(3) Turn the ignition switch on (IG).

(4) Set intelligent tester to test mode (select "TEST MODE"). HINT:

Refer to the intelligent tester operator's manual for further details. (b) 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.

(c) Turn the ignition switch off and disconnect the intelligent tester.
