Perform Zero Point Calibration of Yaw Rate Sensor and/or Brake Actuator Assy (Using Hand-Held Tester)

IF NECESSARY, PERFORM ZERO POINT CALIBRATION OF YAW RATE SENSOR AND/OR BRAKE ACTUATOR ASSEMBLY (USING HAND-HELD TESTER)

NOTE:
- While obtaining the zero point, do not tilt, move or shake the vehicle but keep it in a stationary condition. (Do not start the engine.)
- Be sure to perform the operation on a level surface (within an inclination of 1 %).

a. Check that the steering wheel is in the straight-ahead position and shift the shift lever to the P position.
b. Connect the hand-held tester to the DLC3.
c. Turn the ignition switch to the ON position.
d. Operate the hand-held tester to clear zero point calibration.






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

e. Operate the hand-held tester to test mode.
f. Obtain zero point of the yaw rate sensor and deceleration sensor:
1. Keep the vehicle in a 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.

g. Turn the ignition switch off.
