NORMAL OPERATING CONDITION
Description
INFOID:0000000009365137
Symptom
Result
Slight vibrations are felt on the brake pedal and operation noises occur when ABS is activated.
This is a normal condi-
tion due to the ABS acti-
vation.
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 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.
