CALIBRATION
HINT: Perform the calibration of the acceleration sensor zero point by following the procedures below 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)
NOTICE:
- 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 light blinks in the pattern shown in the illustration.
- The KDSS indicator light blinking pattern changes when the zero point calibration starts and returns to the normal pattern when the calibration ends.
- The KDSS indicator light 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 C1779/79 is not output Kinetic Dynamic Suspension System.
(7) Turn the ignition switch off.
2. PERFORM ZERO POINT CALIBRATION (USING TECHSTREAM)
NOTICE:
- 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 Techstream to the DLC3.
(2) Turn the ignition switch to the ON position.
(3) Turn the Techstream on.
(4) Select the "Sensor Adjustment" mode on the Techstream.
(5) Clear and obtain the zero point calibration value.




(6) Check that the KDSS indicator light blinks in the pattern shown in the illustration.
- The KDSS indicator light blinking pattern changes when the zero point calibration starts and returns to the normal pattern when the calibration ends.
- The KDSS indicator light 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 C1779/79 is not output Kinetic Dynamic Suspension System.
(8) Disconnect the Techstream from the DLC3.
(9) Turn the ignition switch off.
