If master cylinder pressure sensor check can not be com-
pleted, do not depress the brake pedal frequently. It may
further reduce negative pressure and make the sensor
check difficult to complete.

If the negative pressure is insufficient, master cylinder
pressure sensor check may not be completed. In this
case, idle the engine to get enough negative pressure.

If the brake pedal is depressed while engine is stopped,
negative pressure may become insufficient and the BRL
may come on. (It runs the motor and performs incorrect
control.)
(c) Check the yaw rate sensor:
(1) Shift the shift lever to the D position and drive the
vehicle at a speed of approx. 3 mph (5 km/h), turn
the steering wheel either to the left or right 90° or
more, and maintain a 180° circular drive for the ve-
hicle.
(2) Stop the vehicle and shift the shift lever to the P
position, and check that the skid control buzzer
sounds for 3 sec.
NOTICE:
Deceleration sensor check should be completed before
performing speed sensor check.
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 DTCs.

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 signal:
(1) Drive the vehicle straight forward at 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.
NOTICE:

Before performing speed sensor check, complete
master cylinder pressure sensor and deceleration
sensor checks.

Speed sensor check may not be completed if speed
sensor check is started while turning the steering
wheel or spinning the wheels.

After the ABS warning light goes off, if the vehicle
speed exceeds 50 mph (80 km/h), sensor check code
is stored again. Decelerate or stop the vehicle before
the speed reaches 50 mph (80 km/h).

If sensor check has not been completed, the ABS
warning light blinks while driving and ABS system
does not operate.
HINT:
When sensor check has been completed, the ABS warning light
goes off while driving and blinks in the test mode pattern while
standing.
(3) Using SST, connect terminals Tc and CG of the
DLC3.
SST 09843-18040
(4) Read the number of blinks of the ABS warning light
and VSC warning light.
HINT:

See the list of DTC. (See page 05-779)

If the check result is OK, the ABS warning light link goes
off when the brake pedal is once depressed.

If every sensor is normal, the normal blinking patterns are
output. (A cycle of 0.25 seconds ON and 0.25 seconds
OFF is repeated.)

If 2 or more malfunctions are detected at the same time,
the lowest numbered code will be displayed first.
(5) After performing the check, disconnect the SST
from terminals Ts and CG, Tc and CG of the DLC3
and turn the ignition switch to the off position.
