(c) Check the yaw rate:
(1) Shift the shift lever to the D position and drive the
vehicle at a speed of approx. 3 mph (5 km/h), and
maintain a 180° circular drive for the vehicle.
(2) Stop the vehicle and shift the shift lever to the P
position, and check that the skid control buzzer
sounds for 3 seconds.
HINT:
If the skid control buzzer sounds, the sensor check is
completed normally.
If the skid control buzzer does not sound, check the skid
control buzzer circuit (See page 05-866), then perform
the sensor check again. If the skid control buzzer still does
not sound, there is a malfunction in the VSC sensor, so
check for DTC.
Drive the vehicle in a 180° circle. At the end of the turn,
ensure that the vehicle is exactly 180° within a tolerance
of ± 5°, and facing the other direction from its original
start position.
Do not spin the wheels.
(d) Check the speed sensor:
(1) Drive the vehicle straight forward at the speed of 28
mph (45 km/h) or higher for several seconds and
check that the ABS warning light goes off.
HINT:
The sensor check may not be completed if the vehicle has its
wheels spun or its steering wheel turned during this check.
(2) Stop the vehicle.
(e) Read the DTC following the tester screen.
HINT:
Refer to the hand-held tester operator's manual for fur-
ther details.
If the check result is OK, the ABS warning light link goes
off when the brake pedal is once depressed.
9. IF NECESSARY, PERFORM ZERO POINT CALIBRA-
TION OF YAW RATE SENSOR AND/OR BRAKE AC-
TUATOR ASSY (USING SST CHECK WIRE)
NOTICE:
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) Clear the zero point calibration:
HINT:
When replacing the yaw rate sensor only (not replace the brake
actuator assy).
(1) Turn the ignition switch to the ON position.

10. IF NECESSARY, PERFORM ZERO POINT CALIBRATION OF YAW RATE SENSOR AND/OR
BRAKE ACTUATOR ASSY (USING HAND-HELD TESTER)
NOTICE:
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) Perform the reset memory by following the prompts on the tester screen.
HINT:
When replace the yaw rate sensor only (not replace the brake actuator assy).
