Yaw Rate Sensor: Testing and Inspection

PERFORM ZERO POINT OF YAW RATE/SIDE/DECEL G SENSOR: Description
^ After replacing the VDC relevant components or performing "Front wheel alignment adjustment", clear and read the sensor calibration data.
^ Follow the chart to perform calibration.





PERFORM ZERO POINT OF YAW RATE/SIDE/DECEL G SENSOR: Special Repair Requirement

CAUTION:
^ While obtaining the zero point, keep the vehicle stationary and do not vibrate, tilt, move, or shake it.
^ Be sure to perform this procedure on a level surface (with an inclination of less than 1 degree).

1. Clear the zero point calibration data.
a. Turn the ignition switch OFF.
b. Connect the CONSULT-III.
c. Check that the steering wheel is centered and move the shift lever to the P position.
d. Turn the ignition switch ON with the brake pedal released.
e. Operate the CONSULT-III to erase the codes.
f. Turn the ignition switch OFF.
2. Perform zero point calibration of the yaw rate/side/decel G sensor.
a. Turn the ignition switch OFF.
b. Check that the steering wheel is centered and move the shift lever to the P position.

CAUTION:
DTCs C1210 and C1336 will be recorded if the shift lever is not in the P position.

c. Connect the CONSULT-III.
d. Turn the ignition switch ON (READY) with the brake pedal depressed.
e. Select "TEST MODE" in "WORK SUPPORT" to start TEST MODE.
f. Leave the vehicle stationary without depressing the brake pedal for 1 or 2 minutes.
g. Check that the interval between blinks of the Electronically Controlled Brake warning lamp changes from 1 second to 0.5 seconds.

NOTE:
^ The zero point calibration is performed only once after the system enters the Test Mode.
^ Calibration cannot be performed again until the stored data is cleared.

h. Select "TEST MODE END".
i. Turn the ignition switch OFF and disconnect the CONSULT-III.
j. Perform the zero point of steering angle sensor.
