Calibration
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.
USING HAND-HELD TESTER:
2. CLEAR ZERO POINT CALIBRATION
a. Connect the hand-held tester to the DLC3.
b. Turn the ignition switch on (IG).
c. Operate the hand-held tester to erase the codes (select "RESET MEMORY").
HINT: Refer to the hand-held tester operator's manual for further details.
d. Using the hand-held tester, perform zero point calibration of the yaw rate and deceleration sensor (refer to step 3).
3. PERFORM ZERO POINT CALIBRATION OF YAW RATE SENSOR AND DECELERATION 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).
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.
NOTE: DTC C1210/36 and C1336/39 will be recorded if the shift lever is not in the P position.
2. Connect the hand-held tester to the DLC3.
3. Turn the ignition switch on (IG).
4. Set the hand-held tester to test mode (select "TEST MODE").
HINT: Refer to the hand-held tester operator's manual for further details.
b. Obtain the zero point of the yaw rate sensor and deceleration 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 hand-held tester.
USING SST CHECK WIRE:
4. CLEAR ZERO POINT CALIBRATION
a. Turn the ignition switch on (IG).
b. Using SST, connect and disconnect terminals TS and CG of the DLC3 4 times or more within 8 seconds.
SST 09843-18040
c. Check that the VSC warning light indicates the normal system code.
d. Remove the SST from the terminals of the DLC3.
e. Using a check wire, perform zero point calibration of the yaw rate and deceleration sensor (refer to step 5).
5. PERFORM ZERO POINT CALIBRATION OF YAW RATE SENSOR AND DECELERATION 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).
