ABS (ANTI-LOCK BRAKE SYSTEM)

8-160

Fault code No.

ABS_41

Symptom

Front wheel will not recover from the locking
tendency even though the signal is continu-
ously transmitted from the ABS ECU to release
the hydraulic pressure (when the battery volt-
age is normal)

Order

Item/components and probable
cause

Check or maintenance job

Reinstatement
confirmation
method

1

Rotation of wheel

• Check that there is no brake

disc drag on the front wheel and
make sure that it rotates
smoothly.

• Check the front wheel axle for

loose bearings and bends, and
the brake discs for distortion.
Refer to “CHECKING THE
FRONT BRAKE DISCS” on
page 4-35.

Perform hydrau-
lic unit opera-
tion test 1 and
check that the
operation of the
hydraulic unit is
normal.

2

Brake master cylinder and brake cali-
per

• Check that the brake fluid pres-

sure is correctly transmitted to
the brake calipers when the
front brake lever is operated
and that the pressure
decreases when the lever is
released.

3

Brake fluid

• Visually check the brake fluid in

the brake master cylinder reser-
voir for water, foreign materials,
solidification, and contamina-
tion.

• Check for air in the brake lines.
