GENERAL DESCRIPTION
COMPONENTS/PARTS LOCATION AND BRAKE HOSE/PIPE ROUTING
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 has also the following function.
While braking is applied, but before ABS control becomes effective, braking force is distributed between the front
and rear so as to prevent the rear wheels from being locked too early for better stability of the vehicle.

ANTILOCK BRAKE SYSTEM (ABS) 5E-3
The main component parts of this ABS include the 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.
ABS warning lamp which lights to inform abnormality when system fails to operate properly.
ABS hydraulic unit/control module assembly is incorporated ABS control module, ABS hydraulic unit (actua-
tor assembly), fail-safe relay and pump motor relay.
–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 4 wheels.
–Fail-safe relay (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.
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 sen-
sor independently of change of load due to load capacity and so on. And if the EBD system fails to operate prop-
erly, the brake warning lamp lights to inform abnormality.

TABLE – A ABS WARNING LAMP CIRCUIT CHECK – LAMP DOES NOT COME
“ON” AT IGNITION SWITCH ON
CIRCUIT DESCRIPTION
Operation (ON/OFF) of ABS warning lamp is controlled by ABS control module through lamp driver module in
combination meter.
If the Antilock brake system is in good condition, ABS control module turns ABS warning lamp ON at the ignition
switch ON, keeps it ON for 2 seconds and then turns it OFF. If an abnormality in the system is detected, ABS
warning lamp is turned ON continuously by ABS control module. Also, it is turned ON continuously by lamp
driver module when the connector of ABS control module is disconnected.
INSPECTION
1. Main fuse 5. ABS warning lamp 9. Brake fluid level switch
2. Ignition switch 6. Brake warning lamp 10. ABS hydraulic unit/control module assembly
3. Circuit fuse 7. Lamp driver module 11. ABS hydraulic unit/control module connector
4. Combination meter 8. Parking brake switch
Step Action Yes No
1 1) Turn ignition switch ON.
Do other warning lamp come ON?Go to Step 2. Go to Step 4.
2 1) Disconnect ABS hydraulic unit/control mod-
ule connector.
Does ABS warning lamp light with ignition
switch ON?Substitute a known-good ABS
hydraulic unit/control module
assembly and recheck.Go to Step 3.
3 1) Remove combination meter.
Is bulb of ABS warning lamp in good condition?“RED/BLU” circuit shorted to
ground. If OK, replace combina-
tion meter (lamp driver module).Replace bulb.
4 Is IG fuse in good condition? Open in “BLK/WHT” wire to
combination meter or poor con-
nection.Repair and replace.

TABLE – E EBD WARNING LAMP (BRAKE WARNING LAMP) CHECK – LAMP
COMES “ON” STEADY
CIRCUIT DESCRIPTION
EBD warning lamp (brake warning lamp) is controlled by parking brake switch, brake fluid level switch and ABS
control module/hydraulic unit assembly through lamp driver module in combination meter. Refer to “TABLE – A”
for circuit diagram.
INSPECTION
Step Action Yes No
1 1) Make sure that :
Parking brake is completely released.
Brake fluid level is upper than the minimum
level.
Are the check results OK?Go to Step 2. Release parking brake
completely and/or replen-
ish brake fluid.
2Does “ABS” warning lamp come on? Perform “TABLE – B” pre-
viously outlined.Go to Step 3.
3 1) Disconnect ABS hydraulic unit/control mod-
ule connector.
2) Check for proper connection to ABS
hydraulic unit/control module connector at
terminals “E19-10”.
3) If OK, apply chocks to wheels and select
gear in neutral position (P range for A/T).
4) Keep brake pedal depressed and start
engine.
Release parking brake.
5) Connect terminal “E19-10” of disconnected
connector to ground using service wire.
Does EBD warning lamp (brake warning lamp)
turn off?Substitute a known-good
ABS hydraulic unit/con-
trol module assembly and
recheck.“PNK/BLU” circuit open.
If wire and connection are
OK, replace combination
meter.
