CAUTION
When servicing brake assemblies or components, do not create dust by san\
ding, grinding or by cleaning
brake parts with a
dry brush or with compressed air. A WATER DAMPENED CLOTH SHOULD BE USED.
Many brake components contain asbestos fibers which can become air-borne\
if dust is created during
service operations. Breathing dust which contains asbestos fibers can ca\
use
seriouj bodily harm.

SERVICE BRAKES - Anti-lock Braking System Troubleshooting35-15
ANTI-LOCK BRAKING SYSTEM
TROUBLESHOOTINGM35EElAE
PARTICULAR CHARACTERISTICS OF
THE ANTI-LOCK BRAKING SYSTEM
Models equipped with the anti-lock braking system
(A.B.S.) may exhibit one or more of the following
characteristics from time to time, but none of these
is abnormal.
(1)
(2)
A pulsing feeling in the brake pedal, or vibration
of the body or the steering wheel, when the
anti-lock braking system is activated by sudden
braking or by braking on a slippery road surface.
Actually, this phenomenon is an indication that
the anti-lock braking system is functioning nor-
mally.
When the vehicle speed reaches approximately
6 km/h (4 mph) after the engine is started and
the vehicle starts off (for the first time), awhining motor noise may be heard from the
engine compartment if the vehicle is traveling in
a quiet place. This noise is simply the result of a
self-check being made of the anti-lock braking
system operation.
TROUBLESHOOTING METHODS
Problems related to the anti-lock braking system
(A.B.S.) can be classified into two general categor-
ies: problems in the electrical system and those in
the hydraulic system. For problems in the electrical system, the on-board
diagnostic is built into the electronic control unit
(E.C.U.) causing the A.B.S. warning light to illuminate
as a warning to the driver. In this instance, checks
can be made by using the scan tool and oscillo-
scope.
Problems in the hydraulic system (poor braking,
etc.) can be located in the same way as for ordinary
brakes. There is, however, the necessity to check to
determine whether the problem is related to ordi-
nary brake components or to the components re-
lated to the A.B.S. To make this check, use the scan
tool.
HOW TO USE THE TROUBLESHOOTING
FLOW CHART
(1) Using the flow chart, check the ABS warning
light light-up sequence. Read the diagnostic
trouble codes and check the condition of bra-
king operation.
(2) Following the check chart listed in the remedy
column, perform the checks. There are [Expla- nation] and [Hint] in each check chart. Refer to
them when troubleshooting.
