Calibration

CALIBRATION

HINT: Perform the calibration of the acceleration sensor zero point by following the procedures after replacing the acceleration sensor assembly or stabilizer control ECU, or after clearing the ECU memory.

1. PERFORM ZERO POINT CALIBRATION (USING SST CHECK WIRE)

NOTE:
- Do not tilt, move or shake the vehicle during the zero point calibration. Keep it stationary.
- Be sure to perform the procedures on level ground (inclination of 1% or less).

a. Clear the zero point calibration value.
1. Turn the ignition switch to the ON position.




2. Connect terminals TS and CG of the DLC3 using SST. Perform this procedure 4 times or more within 8 seconds.
SST 09843-18040

3. Disconnect the SST from the terminals of the DLC3.

b. Obtain the zero point calibration value.
1. Turn the ignition switch off.
2. Connect terminals TS and CG of the DLC3 using SST.
SST 09843-18040

3. Turn the ignition switch to the ON position to enter the test mode.







4. Check that the KDSS indicator lamp blinks in the pattern shown in the illustration.

HINT:
- The KDSS indicator lamp blinking pattern changes when the zero point calibration starts and returns to the normal pattern when the calibration ends.

- The KDSS indicator lamp does not return to the normal blinking pattern when the zero point calibration cannot be completed.

- When the zero point calibration cannot be completed, check if the following conditions necessary for performing the calibration are met:
- Vehicle speed is 0 mph (0 km/h).
- The acceleration sensor assembly is normal.
- Acceleration sensor assembly power source voltage is normal.

5. Disconnect the SST from the DLC3 terminals.
6. Check that DTC C1879/79 is not output.
7. Turn the ignition switch off.

2. PERFORM ZERO POINT CALIBRATION (USING HAND-HELD TESTER)

NOTE:
- Do not tilt, move or shake the vehicle during the zero point calibration. Keep it stationary.
- Be sure to perform the procedures on level ground (inclination of 1% or less).

a. Clear and obtain the zero point calibration value.




1. Connect the hand-held tester to the DLC3.
2. Turn the ignition switch to the ON position.
3. Turn the hand-held tester main switch on.
4. Select the SENSOR ADJUST mode on the hand- held tester.
5. Clear and obtain the zero point calibration value.







6. Check that the KDSS indicator lamp blinks in the pattern shown in the illustration.

HINT:
- The KDSS indicator lamp blinking pattern changes when the zero point calibration starts and returns to the normal pattern when the calibration ends.
- The KDSS indicator lamp does not return to the normal blinking pattern when the zero point calibration cannot be completed.
- When the zero point calibration cannot be completed, check if the following conditions necessary for performing the calibration are met:
- Vehicle speed is 0 mph (0 km/h).
- The acceleration sensor assembly is normal.
- Acceleration sensor assembly power source voltage is normal.

7. Check that DTC C1879/79 is not output.
8. Disconnect the hand-held tester from the DLC3.
9. Turn the ignition switch off.
