Yaw Rate Sensor: Testing and Inspection
With TOYOTA Hand-Held Tester
IF NECESSARY, PERFORM ZERO POINT CALIBRATION OF YAW RATE SENSOR AND DECELERATION SENSOR (USING
HAND-HELD TESTER)
HINT: When having replaced the yaw rate sensor and/or the brake actuator assembly, make sure to perform yaw rate sensor and deceleration sensor
zero point calibration.
NOTE:
-
While obtaining the zero point, do not give any vibration to the vehicle by tilting, moving or shaking it and keep it in a stationary condition. (Do
not start the engine.)
-
Be sure to do this on a level surface (within an inclination of 1 %).
a. Shift the shift lever to P position.
b. Hook up the hand-held tester to the DLC3.
c. Operate the hand-held tester to clear zero point calibration.
d. Operate the hand-held tester to test mode.
e. Turn the ignition switch ON.
f.
Keep the vehicle in the stationary condition on the level surface for 2 sec. or more.
g. Check that the VSC warning light blink.
HINT: If the VSC warning light does not blink, perform the zero point calibration again.
