Yaw Rate Sensor Zero Point Calibration

NOTE: While obtaining the zero point, keep the vehicle in stationary condition and do not tilt, move or shake the vehicle. Be sure to perform this on a level surface.
  1. Shift transmission lever to P and turn ignition switch ON.
  2. Using special tool (09843-18040), repeat a cycle of short and open between terminals Ts and CG of DLC3 four times or more within 8 seconds. Check that the TRC OFF indicator light is illuminated indicating the recorded zero point is erased.
  3. Turn the ignition switch off. Remove special tool between terminals Ts and CG of DLC3.
  4. Turn the ignition switch ON. Check that the illuminated TRC OFF indicator light turns off about 15 seconds after the ignition switch is turned ON.
  5. Ensure that the TRC OFF indicator light remains off for 2 seconds. Turn the ignition switch off. Even if the ignition is not turned off, the yaw rate sensor zero point calibration can be completed. In this case, the TRC OFF indicator light will light for about 15 seconds and then start flashing (normal code). Make sure that the indicator light blinks for 2 seconds and then turn off the ignition switch.
  6. Perform deceleration sensor zero point calibration. If the vehicle is driven without this calibration, deceleration sensor zero point calibration malfunction will be detected and the VSC warning light will light up. See DECELERATION SENSOR ZERO POINT CALIBRATION  under PROGRAMMING.
