Yaw Rate Sensor Zero Point Calibration

NOTE: If yaw rate sensor, deceleration sensor or ABS ECU have been replaced, be sure to perform yaw rate and deceleration sensor zero point calibration. Perform yaw rate calibration first and then be sure to continue on to deceleration sensor.

NOTE: While obtaining zero point, do not tilt, move or shake vehicle. Be sure to perform operation on a level surface.

Shift selector lever to Park position. Turn ignition switch on.
Using special tool (09843-18020), repeat a cycle of short and open between terminals Ts and E₁ of (DLC1) 4 times or more within 8 seconds. See Figure. Check that VSC warning light is lit indicating the recorded zero point is erased.
Turn ignition switch off. Remove special tool.
Turn ignition switch on. Check that VSC warning light turns off after approximately 15 seconds.
Ensure that TRAC OFF and VSC indicator lights remain off for 2 seconds. Turn ignition switch off. Even if ignition is not turned off, the yaw rate sensor zero point calibration can be completed. In this case, VSC warning light will illuminate for approximately 15 seconds and then start flashing (normal code). Make sure that indicator light flashes for 2 seconds and then turn off ignition switch.
Perform deceleration sensor zero point calibration. If vehicle is driven without this calibration, deceleration sensor zero point calibration malfunction will be detected and VSC warning light will illuminate. See DECELERATION SENSOR ZERO POINT CALIBRATION .
