2001 TOYOTA COROLLA brake sensor

1532001MY_COROLLA_U (OM12720U)
You may hear a click or motor sound in
the engine compartment for a few seconds
when the engine is started or just after
the vehicle is started. This means that the
anti±lock brake system is in the self
check mode, and does not indicate a mal-
function.
When the anti±lock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:

You may hear the anti±lock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.

At the end of the anti±lock brake sys-
tem activation, the brake pedal may
move a little forward.
CAUTION
Do not overestimate the anti±lock
brake system: Although the anti±lock
brake system assists in providing ve-
hicle control, it is still important to
drive with all due care and maintain
a moderate speed and safe distance
from the vehicle in front of you, be-
cause there are limits to the vehicle
stability and effectiveness of steering
wheel operation even with the anti±
lock brake system on.
If tires grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the anti±lock brake system does not
provide vehicle control.
Anti±lock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at the moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles without an
anti±lock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:

Driving on rough, gravel or snow±
covered roads.

Driving with tire chains installed.

Driving over the steps such as the
joints on the road.

Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The anti±lock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels' turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed
resulting in a longer stopping dis-
tance.
