Symptom TableINFOID:0000000012430917
If ABS warning lamp and SLIP indicator
lamp turn ON, perform self diagnostic.
NOTE:
• 1: The ABS does not operate when the speed is 10 km/h (6 MPH) or less.
• 2: Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly depressed (just place a foot on it).
However, this is normal:
- When shifting gears
- When driving on slippery road
- During cornering at high speed
- When passing over bumps or grooves [approximately 50 mm (1.97 in) or more]
- When pulling away just after starting engine [at approximately 10 km/h (6 MPH) or higher] Symptom

NORMAL OPERATING CONDITION
DescriptionINFOID:0000000012430924
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-
diagnostic result memo-
ry.
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.

CAUTION:
• Be careful not to damage front wheel
sensor edge and sensor rotor teeth.
• When removing the front wheel hub, first remove the front wheel sensor from the steering knuckle.
Failure to do so may result in damage to the fr ont wheel sensor, making the front wheel sensor inop-
erative.
• Pull out the front wheel sensor, bein g careful to turn it as little as possible. Do not pull on the front
wheel sensor harness.
• Before installation, check if foreign objects, such as iron fragments, are adhered to the pick-up part
of the front wheel sensor or to the inside of the hole in the steer ing knuckle for the front wheel sen-
sor, or if a foreign object is caught in the surface of the sensor rotor. Fix as necessary and then
install the front wheel sensor.
REMOVAL
1. Remove wheel and tire using power tool. Refer to WT-48, "Removal and Installation".
2. Remove fender protector. Refer to EXT-38, "
