AIR BAG STEERING WHEEL AND COLUMN 3C1-11
Checking Steering Column and Steering
Upper Shaft for Accident Damage
Check that 2 capsules are attached to steering column
bracket securely. Check clearance between capsules and
steering column bracket. Clearance should be 0 mm (0 in.)
on both sides. If found loose or clearance, replace steering
column assembly.

than specified length, replace column assembly with new
one.
Steering column assembly length “a” :
490.3 ± 1.0 mm (19.30 ± 0.04 in.)
Check steering shaft for smooth rotation.
If found defective, replace as column assembly.
Check steering shaft and column for bend, cracks or defor-
mation.
If found defective, replace as column assembly.
Check steering upper shaft lower seal (1) for breakage or
deformation.
If found defective, replace.
Check steering shaft joints and shaft for any damages such
as crack, breakage, malfunction or excessive play.
If anything is found faulty, replace steering upper shaft
assembly, steering lower shaft assembly or steering column
assembly. NOTE:
Vehicles involved in accidents resulting in body damage,
where steering column has been impacted or air bag
deployed, may have a damaged or misaligned steering
column.

BRAKES PIPE/HOSE/MASTER CYLINDER 5A-3
On-Vehicle Service
Front Brake Hose/Pipe
REMOVAL
1) Raise and suitably support vehicle. Remove tire and wheel.
This operation is not necessary when removing pipes connecting master cylinder and flexible hose.
2) Clean dirt and foreign material from both hose end or pipe end fittings. Remove brake hose or pipe.
INSTALLATION
1) Reverse removal procedure for brake hose and pipe installation procedure.
For installation, make sure that steering wheel is in straightforward position and hose has no twist or kink.
Check to make sure that hose doesn't contact any part of suspension, both in extreme right and extreme left
turn conditions. If it does at any point, remove and correct. Fill and maintain brake fluid level in reservoir.
Bleed brake system.
2) Perform brake test and check installed part for fluid leakage.

ANTILOCK BRAKE SYSTEM (ABS) 5E2-3
General Description
Components/Parts Location
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.The
main component parts of this ABS include the following parts in addition to those of the conventional brake sys-
tem.
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.

ENGINE GENERAL INFORMATION AND DIAGNOSIS (H27 ENGINE) 6-1-5
Fuel Pressure Relief Procedure
After making sure that engine is cold, relief fuel pressure as fol-
lows.
1) Place transmission gear shift lever in “Neutral” (shift selector
lever to “P” range for A/T vehicle), set parking brake, and
block drive wheels.
2) Remove fuel pump relay (1) from its connector.
3) Remove fuel filler cap to release fuel vapor pressure in fuel
tank and then reinstall it.
4) Start engine and run it till it stops for lack of fuel. Repeat
cranking engine 2 – 3 times of about 3 seconds each time to
dissipate fuel pressure in lines. Fuel connections are now
safe for servicing.
5) Upon completion of servicing, install fuel pump relay to relay
box.
Fuel Leakage Check Procedure
After performing any service on fuel system, check to make sure
that there are no fuel leakages as follows.
1) Turn ON ignition switch for 3 seconds (to operate fuel pump)
and then turn it OFF.
Repeat this (ON and OFF) 3 or 4 times and apply fuel pres-
sure to fuel line (till fuel pressure is felt by hand placed on
fuel return hose).
2) In this state, check to see that there are no fuel leakages
from any part of fuel system. CAUTION:
This work must not be done when engine is hot. If done
so, it may cause adverse effect to catalyst.
