Calibration

CALIBRATION

1. DESCRIPTION
a. After replacing the VSC relevant components or performing "Front wheel alignment adjustment", clearing and reading the sensor calibration data are necessary.




b. Follow the chart to perform calibration.

2. CLEAR ZERO POINT CALIBRATION (USING SST CHECK WIRE)

HINT: After replacing the yaw rate and deceleration sensor, make sure to clear zero point calibration data in the skid control ECU and perform zero point calibration.

a. Clear the zero point calibration using the SST check wire.

SST 09843-18040

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.
3. Check that the warning light indicates the normal code.
4. Remove the SST.

3. PERFORM ZERO POINT CALIBRATION OF YAW RATE SENSOR AND DECELERATION SENSOR (USING SST CHECK WIRE)

HINT: After replacing the brake actuator assembly, make sure to perform yaw rate sensor and deceleration sensor zero point calibration.

NOTE:
- While obtaining the zero point, do not give any vibrate the vehicle by tilting, moving or shaking it and keep it in a stationary condition. (Do not start the engine.)
- Be sure to perform this on a level surface (with an inclination less than 1 degree).

a. Shift the shift lever to P position.
b. Clear the zero point calibration.
c. Procedures for test mode:
1. Turn the ignition switch to off.
2. Apply the parking brake is applied (Parking brake switch ON).




3. Using SST, it connects terminal TS and CG of the DLC3.

SST 09843-18040

4. Check that the steering wheel is in the straight-ahead position and move the shift lever to the P position.
5. Turn the ignition switch to the ON position.

d. Keep the vehicle in the stationary condition on a level surface for 2 seconds, or more.
e. Check that the VSC warning light blinks.

HINT:
- If the VSC warning light does not blink, perform the 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.

4. CLEAR ZERO POINT CALIBRATION (USING INTELLIGENT TESTER)
a. Clearing the DTCs.




1. Connect the intelligent tester to the DLC3.
2. Turn the ignition switch to the ON position.
3. Operate the intelligent tester to erase the codes.

HINT: Refer to the intelligent tester Operator's Manual for further details.

5. PERFORM ZERO POINT CALIBRATION OF YAW RATE SENSOR AND DECELERATION SENSOR (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 less than 1 degree)

a. Check that the steering wheel is in the straight-ahead position and move the shift lever to the P position.




b. Connect the intelligent tester to the DLC3.
c. Turn the ignition switch to the ON position.
d. Operate the intelligent tester to test mode (SIGNAL CHECK).
e. 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 blinks.

HINT:
- If the VSC warning light does not blink, perform the 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.

f. Turn the ignition switch off.
