wheel with DTC.
2. Check terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace as necessary.
2.CHECK WHEEL SENSOR OUTPUT SIGNAL
1. Connect ABS active wheel sensor tester (J- 45741) to wheel sensor using appropriate adapter.
2. Turn on the ABS active wheel sensor tester power switch. NOTE:
The green POWER indicator should illuminate. If the POWER indicator does not illuminate, replace the
battery in the ABS active wheel sensor tester before proceeding.
3. Spin the wheel of the vehicle by hand and observe the red SENSOR indicator on the ABS active wheel
sensor tester. The red SENSOR indicator should flash on and off to indicate an output signal.
NOTE:
If the red SENSOR indicator illuminates but does not flash, reverse the polarity of the tester leads and
retest.
Does the ABS active wheel sensor tester detect a signal?
YES >> GO TO 3.
NO >> Replace the wheel sensor. Refer to BRC-124, "Removal and Installation - Front Wheel Sensor"
or
BRC-125, "Removal and Installation - Rear Wheel Sensor"
.

NORMAL OPERATING CONDITION
DescriptionINFOID:0000000009463845
Symptom Result
Slight vibrations are felt on the brake pedal and operation noises occur when VDC, TCS or ABS is activated. This is a normal condi-
tion due to the VDC,
TCS or ABS activation.
Stopping distance is longer than that of vehicles without ABS when the vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.
The brake pedal moves and generates noises when TCS or VDC is activated due to rapid acceleration or
sharp turn.
The brake pedal vibrates and motor operation noises occur from the engine room after the engine starts and
just after the vehicle starts. This is normal, and it is
caused by the ABS op-
eration check.
Depending on the road conditions, the driver may experience a sluggish feel in the brake pedal. This is normal, because TCS places the highest
priority on the optimum
traction (stability).
TCS may activate momentarily if wheel speed changes when driving where road friction coefficient varies,
when downshifting, or when fully depressing accelerator pedal.
The ABS warning lamp and SLIP indicator lamp may turn ON when the vehicle is subject to strong shaking
or large vibration, such as when the vehicle is rotating on a turntable or located on a ship while the engine
is running. In this case, restart the
engine on a normal
road. If the normal con-
dition is restored, there
is no malfunction. At
that time, erase the self-
diagnosis memory.
VDC may not operate normally or th
e ABS warning lamp, and SLIP indicato r lamp may illuminate when driv-
ing on a road that is extremely slanted (e.g., bank in a circuit course).
A malfunction may occur in the yaw rate/side/decel G sensor system when the vehicle turns sharply, such
as during a spin turn, axle turn, or drift driving, while the VDC function is OFF (VDC OFF indicator lamp illu-
minated).
The vehicle speed will not increase even though the accelerator pedal is depressed, when inspecting the
speedometer on a 2-wheel chassis dynamometer. Normal (Deactivate the
VDC/TCS function be-
fore performing an in-
spection on a chassis
dynamometer.)
SLIP indicator lamp may simultaneously turn ON when low tire pressure warning lamp turns ON. This is not a VDC sys-
tem error but results
from characteristic
change of tire.
