BRAKE PEDAL PLAY CHECK
Pedal play should be within specification. If out of specification,
check brake light switch for proper installation position and adjust
if necessary.
Also check pedal shaft bolt and master cylinder pin installation for
looseness and replace if defective.
Pedal play ªdº: 1 ± 8 mm (0.04 ± 0.32 in.)
BRAKE FLUID LEVEL CHECK
Be sure to use particular brake fluid either as indicated on reservoir
cap of that vehicle or recommended in owner's manual which
comes along with that vehicle.
Use of any other fluid is strictly prohibited.
Fluid level should be between MIN and MAX lines marked on reser-
voir.
When warning light lights sometimes during driving, replenish fluid
to MAX line.
When fluid decreases quickly, inspect brake system for leakage.
Correct leaky points and then refill to specified level.
CAUTION:
Do not use shock absorber fluid or any other fluid which
contains mineral oil. Do not use a container which has been
used for mineral oil or a container which is wet from water.
Mineral oil will cause swelling and distortion of rubber parts
in hydraulic brake system and water mixed into brake fluid
will lower fluid boiling point. Keep all fluid containers
capped to prevent contamination.
BRAKE HOSE AND PIPE CHECK
The brake hose assembly should be checked for road hazard dam-
age, for cracks and chafing of the outer cover, for leaks and blisters.
A light and mirror may be needed for an adequate inspection. If any
of the above conditions are observed on the brake hose, it is neces-
sary to replace it.
Inspect the pipe for damage, cracks, dents and corrosion. If any de-
fect is found, replace it.
MASTER CYLINDER CHECK
Check for a cracked master cylinder casting or brake fluid around
the master cylinder. Leaks are indicated only if there is at least a
drop of fluid. A damp condition is not abnormal.

5E1-2 ANTILOCK BRAKE SYSTEM (ABS) (OPTIONAL)
GENERAL DESCRIPTION
The ABS (Antilock Brake System) controls the fluid pressure applied to the wheel cylinder of each brake from the
master cylinder so that each wheel is not locked even when hard braking is applied. This ABS is a 4-wheel type
which controls the fluid pressure applied to the wheel cylinder of each of the four brakes to prevent each wheel
from getting locked.
The component parts of this ABS includes following parts in addition to those of the conventional brake system.

Wheel speed sensor which senses revolution speed of each wheel and outputs its signal.

In this ABS, ABS hydraulic unit (actuator assembly), ABS control module, pump motor relay and fail-safe relay
are combined as one component.

ABS control module which sends operation signal to ABS hydraulic unit to control fluid pressure applied to each
wheel cylinder based on signal from each wheel speed sensor so as to prevent wheel from locking.

ABS hydraulic unit which operates according to signal from ABS control module to control fluid pressure applied
to wheel cylinder of each of 4 wheels.

Fail-safe (solenoid valve) relay which supplies power to solenoid valve in ABS hydraulic unit and pump motor
relay.

Pump motor relay which supplies power to pump motor in ABS hydraulic unit.

ªABSº warning lamp which lights to inform abnormality when system fails to operate properly.

G sensor which detects body deceleration speed. (For 4WD model only)
This ABS is equipped with Electronic Brake force Distribution (EBD) system that controls a fluid pressure of rear
wheels to best condition, which is the same function as that of proportioning valve, by the signal from wheel sensor
independently of change of load due to load capacity and so on. And if the EBD system fails to operate properly,
the brake warning lamp lights to inform abnormality.

ABS HYDRAULIC UNIT/CONTROL MODULE
ASSEMBLY
ABS control module is a component of ABS hydrauli unit / control
module assembly and has the following functions.
Self-Diagnosis Function
ABS control module diagnoses conditions of the system compo-
nent parts (whether or not there is any abnormality) all the time and
indicates the results (warning of abnormality occurrence and DTC)
through the ªABSº warning lamp as described below.
1) When ignition switch is turned ON, ªABSº warning lamp lights for
2 seconds to check its bulb and circuit.
2) When no abnormality has been detected (the system is in good
condition), ªABSº warning lamp turns OFF after 2 seconds.
3) When the vehicle starts to move after the ignition switch is turned
ON (more than one wheel speed sensor signals are inputted),
solenoid valves and motor of ABS hydraulic unit operate once
one after another for electrical check.
During this check, motor operation sound may be heard but that
means nothing abnormal.
4) When an abnormality in the system is detected, ªABSº warning
lamp lights and the area where that abnormality lies is stored in
the memory of EEPROM in ABS control module.
5) When Diag. switch terminal of diagnosis connector (monitor
connector) is grounded, the abnormal area is output as DTC. It
is indicated by flashing of ªABSº warning lamp. (Refer to the
table below. )

For procedure to clear all DTC's, refer to the item ªDiagnostic
Trouble Code Clearanceº in this section.
Also ABS control module turns ON EBD warning lamp (brake warn-
ing lamp) depending on the trouble that detected by the module and
EBD warning lamp does not indicate DTC as well as ªABSº warning
lamp.
Fail-Safe Function
When an abnormality occurs (an abnormal DTC is detected), ABS
control module turns OFF the fail-safe relay which supplies power
to ABS hydraulic unit. Thus, with ABS not operating, brakes func-
tion just like the brake system of the vehicle not equipped with ABS.

NOTE:
Perform this check on a level place.
1) Turn ignition switch ON with parking brake applied.
2) Check that brake warning lamp is turned ON.
3) Release parking brake with ignition switch ON and check that
EBD warning lamp (brake warning lamp) goes off.
If it doesn't go off, go to ªTABLE-Eº in this section.
ªABSº WARNING LAMP CHECK
1) Turn ON the ignition switch.
2) Check that ªABSº warning lamp lights for about 2 seconds and
then goes OFF.
If anything faulty is found, advance to Diagnostic table ± A, B or
C.
DIAGNOSTIC TROUBLE CODE (DTC) CHECK
(USING ªABSº WARNING LAMP)
1) Using service wire, connect diag. switch terminal of diagnosis
connector to ground.
2) Turn ignition switch ON.
3) Read flashing of ªABSº warning lamp which represents DTC as
shown in example below and write it down. When more than 2
DTC's are stored in memory, deflection and flashing for each
DTC is repeated three times starting with the smallest DTC num-
ber in increasing order.
For details of DTC, refer to ªDTC Tableº.
