5. Bleed the air from the rear brake piping.
6. To adjust the LSV correctly, proceed as follows:
a. With unladen vehicle (12 liters of fuel, radiator coolant and
engine oil are full). Spare tire, hand tools and mats in desig-
nated positions. Check the length of LSV spring ªLº.
b. If the spring length is different from that specified, move the
regulation lever (2) until the specified value is obtained. Move
the LSV lever (1) until it contacts the stopper bolt and recheck
the spring length.

NOTE: Do not disturb stopper bolt.
c. Start the engine and run it at idling speed.
d. Slowly depress the brake pedal until an input pressure of 4,805
kPa (48.1 bar, 49 kg/cm

2, 252 - 363 psi) is obtained (at
the rear axle pressure gauge).
If the output pressure at the rear axle pressure gauge is not within
the specified values, adjust LSV spring length as described under

OPERATING CHECK
IDepress brake pedal several times with engine off, and check
that there is no change in pedal stroke.
IDepress brake pedal, then start engine. If pedal goes down
slightly, operation is normal.
AIRTIGHT CHECK
IStart engine, and stop it after one or two minutes. Depress
brake pedal several times slowly. If pedal goes further down the
first time and gradually rises after second or third time, booster
is airtight.
IDepress brake pedal while engine is running, and stop engine
with pedal depressed. If there is no change in pedal stroke after
holding pedal down30 seconds, brake booster is airtight.
OUTPUT ROD LENGTH CHECK
1. Apply vacuum of þ66.7 kPa (þ667 mbar, þ500 mmHg, þ19.69
inHg) to brake booster with a manual vacuum pump and check
output rod length ªAº.
Specified length ªAº:
22.15 - 22.45 mm (0.872 - 0.884 in)
(The length ªAº in this case is the distance from end of output
rod to outside of brake booster, when the specified vacuum is
applied.)

Purpose
The Anti-lock Brake System (ABS) with an integrated Electronic Brake force Distribution (EBD) system con-
sists of electronic and hydraulic components. It allows you to control the braking force so that wheel lock can
be avoided during braking.
The advantages of ABS with EBD
1) Better tracking performance through improved steering wheel control.
2) Improved maneuverability and safer vehicle control.
3) Improved vehicle stability by preventing flat spins.
4) Shorter stopping distance and optimal utilisation of the rear brakes under many different circumstances.
Operation
IABS with EBD has self-test capabilities. The ABS warning lamp is illuminated for 1 second each time the
ignition switch is turned ªONº. After the engine is started, the ABS warning lamp turns off. An ABS self-test
is performed the first time the vehicle reaches 6 km/h (4 MPH) to ensure the system is operational. A
mechanical noise may be heard as the ABS performs this self-test and is a normal part of the self-test
feature. If a malfunction is detected during this check, the ABS warning lamp will stay on.
During the self-test, it also performs a EBD check when it detects a failure the ABS warning light will go
on simultaneously with the brake warning light and an audible sound will sound constantly.
IEBD system will only operate when the ABS is not in active status and it uses the inlet valves of ABS con-
trol unit to limit the pressure to the rear wheels when they tend to go into slip.
IWhen the vehicle speed is less than 10 km/h (6 MPH) the ABS system does not operate.
IWhile driving, a mechanical noise may be heard during ABS operation, this is a normal system condition.

How to Perform Trouble Diagnoses for Quick
and Accurate Repair
INTRODUCTION
The ABS system has an electronic control unit to control major
functions. The control unit accepts input signals from sensors and
uses this data to compute control characteristics to instantly drive
the actuators. It is essential that both kinds of signal are accurate
and stable. It is also important to check for conventional brake
system problems: such as air leaks in booster lines, lack of brake
fluid, or other problems with the brake system.
It is much more difficult to diagnose a problem that occurs intermit-
tently rather than catastrophically. Most intermittent problems are
caused by poor electric connections or faulty wiring. In this case,
careful checking of suspicious circuits may help prevent the
replacement of good parts.
A visual check may not be sufficient to determine the cause of the
problems, so a road test should also be conducted.
Before undertaking actual checks, take a few minutes to talk with
a customer who approaches with an ABS complaint. The customer
is a very good source of information on such problems; especially
intermittent ones. Through the talks with the customer, find out what
symptoms are present and under what conditions they occur.
Start your diagnosis by looking for ªconventionalº problems first.
This is one of the best ways to troubleshoot brake problems on an
ABS controlled vehicle.

CONSULT-II Inspection Procedure
SELF-DIAGNOSIS PROCEDURE
1) Turn ignition switch to OFF position.
2) Connect CONSULT-II to Data Link Con-
nector.
1) Start engine.
2) Drive vehicle over 30 km/h (19 MPH)
for at least one minute.
1) Stop vehicle with engine running
and touch ªSTARTº on CON-
SULT-II screen.
2) Touch ªABSº.
3) Touch ªSELF-DIAG RESULTSº.
IThe screen shows the detected malfunc-
tion and how many times the ignition
switch has been turned since the mal-
function.
Make the necessary repairs following the
diagnostic procedures.
After the malfunctions are repaired, erase
the self-diagnostic results stored in the
control unit by touching ªERASEº.
Check warning lamp(s) for deactivation
after driving vehicle over 30 km/h (19
MPH) for at least one minute.
Test the ABS system in a safe area to
verify that it functions properly.

Note: ªSELF-DIAG RESULTSº screen shows the detected malfunction and
how many times the ignition switch has been turned since the mal-
function.
