NORMAL OPERATING CONDITION

Description

INFOID:0000000005275103

Symptom

Result

Slight vibrations are felt on the brake pedal and the 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.

The ABS 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.

ABS warning lamp may illuminate when running on a special road that is extremely slanted (e.g. bank in a 
circuit course).
