OPERATING CHECK
IDepress brake pedal several times with engine off, and check
that there is no change in pedal stroke.
I Depress 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.
I Depress brake pedal while engine is running, and stop engine
with pedal depressed. If there is no change in pedal stroke after
holding pedal down 30 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.)

ICheck inner wall of vacuum pump housing for wear. If
necessary, replace.
I Check rotor shaft for wear. If necessary, replace.
I Check valve locations and copper washers for bends or defor-
mation. If necessary, replace.
I Check that valve operates smoothly when slightly pushed.
Replace if necessary.
I Check for air leakage with 98 to 490 kPa (1.0 to 4.9 bar, 1 to
5 kg/cm
2, 14 to 71 psi) of air pressure.
Replace if necessary.

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.
I EBD 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.
I When the vehicle speed is less than 10 km/h (6 MPH) the ABS system does not operate.
I While driving, a mechanical noise may be heard during ABS operation, this is a normal system condition.

Checking Fluid Leakage
Check the lines for improper attachment and for leaks, cracks,
damage, loose connections, chafing or deterioration.
1. Run engine between idle speed and 1,000 rpm.
Make sure temperature of fluid in oil tank rises to 50 to 80ÉC
(122 to 176ÉF).
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each ªlockº position for five seconds andcarefully check for fluid leakage.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 10 seconds (There is possibility that oil pump may be
damaged.).
4. If fluid leakage at connectors is noticed, loosen flare nut and then retighten.
Do not overtighten connector as this can damage O-ring,
washer and connector.
5. If fluid leakage at the connectors are noticed, then loosen the flare nut and retighten it.
Bleeding Hydraulic System
1. Raise front end of vehicle until wheels are clear of the ground.
2. Add fluid into oil tank to specified level. Meanwhile quickly turnsteering wheel fully to right and left and lightly touch steering
stoppers.
Repeat steering wheel operation until fluid level no longer
decreases.
3. Start engine. Repeat step 2 above.
I Incomplete air bleeding will cause the following to occur. When
this happens, bleed air again.
a. Generation of air bubbles in reservoir tank
b. Generation of clicking noise in oil pump
c. Excessive buzzing in oil pump
While the vehicle is stationary or while moving the steering wheel
slowly, fluid noise may occur in the valve or oil pump. This noise is
inherent in this steering system, and it will not affect performance
or durability of the system.

Operation Check
The purpose of the operational check is to confirm that the system
is as it should be. The systems which will be checked are the
blower, mode (discharge air), intake air, temperature decrease,
temperature increase and A/C switch system.
CONDITIONS:
Engine running and at normal operating temperature.
PROCEDURE:
1. Check blower
1) Turn FAN CONTROL DIAL to 1.Blower should operate at speed 1.
2) Then turn the DIAL to speed 2.
3) Continue checking blower speed until all speeds are checked.
4) Leave blower on speed 4.
2. Check discharge air
1) Turn AIR CONTROL DIAL toposition.
2) Confirm that all discharge air comes out of face vents.
3) Turn AIR CONTROL DIAL to
position.
4) Confirm that discharge air comes out of face vents and foot vents.
5) Turn AIR CONTROL DIAL to
position.
6) Confirm that discharge air comes out of foot vents, with some air from face vents.
7) Turn AIR CONTROL DIAL to
position.
8) Confirm that discharge air comes out of foot vents with some air from defroster vents.
9) Turn AIR CONTROL DIAL to
position.
10) Confirm that all discharge air comes out of defroster vents, with some air from face vents.
3. Check recirculation
1) Switch AIR RECIRCULATION SWITCH to ON position (Indica-tor light ON).
2) Listen for intake door position change (you should hear sound change slightly).
