CAUTION:

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 [at approximately 50 mm (1.97 in) or more]
• When pulling away just after starting engine [at approximately 10 km/h (6 MPH) or higher]

NORMAL OPERATING CONDITION

[WITH VDC]

NORMAL OPERATING CONDITION

Description

INFOID:0000000007565839

Symptom

Result

Slight vibrations are felt on the brake pedal and the operation noises occur, when VDC, TCS or ABS is acti-
vated.

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 a normal, and it is
caused by the ABS op-
eration check.

Depending on the road conditions, the driver may experience a sluggish feel.

This is normal, because
TCS places the highest
priority on the optimum
traction (stability).

TCS may activate momentarily if wheel speed changes when driving over location where friction coefficient
varies, when downshifting, or when fully depressing accelerator pedal.

The ABS warning lamp and VDC warning 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 the ABS warning lamp and VDC warning lamp may illuminate, when run-
ning on a special road that is extremely slanted (e.g. bank in a circuit course).

A malfunction may occur in the yaw rate/side G sensor system, when the vehicle turns sharply, such as dur-
ing a spin turn, axle turn, or drift driving, while the VDC function is off (VDC warning lamp illuminated).

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.)

Be careful with the following when removing sensor.

CAUTION:

• Never twist sensor harness as much as possible, when removing it. Pull sensors out without pulling

sensor harness.

• Be careful to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before remov-

ing front or rear wheel hub. This is to avoid damage to sensor wiring and loss of sensor function.

• When you see the harness of the wheel sensor from the front side of the vehicle ensure that the

color lines (B) are not twisted.
