POWER±ASSISTED STEERING SYSTEM
The steering column has three important features in
addition to the steering function:
1. The column is energy absorbing, designed to
compress in a front-end collision to minimize the
possibility of injury to the driver of the vehicle.
2. The ignition switch and lock are mounted
conveniently on the column.
3. With the column mounted lock, the ignition and
steering operation can be locked to prevent theft of
the vehicle.The column can be disassembled and reassembled.
However, to insure the energy absorbing action, use only
the specified screws, bolts and nuts as designated, and
tighten them to the specified torque.
Handle the column with care when it is removed from the
vehicle. A sharp blow on the end of steering shaft or shift
lever, or dropping the assembly could shear or loosen the
fasteners that maintain column rigidity.
Power Steering System Test
Test Procedure

Legend
(1) Fluid Reservoir(2) Power Steering Unit
(3) Power Steering Pump
Test of fluid pressure in the power steering system is
performed to determine whether or not the oil pump and
power steering unit are functioning normally.
The power steering system test is used to identify and
isolate hydraulic circuit difficulties. Prior to performing
this test, the following inspections and corrections, if
necessary, must be made.

Inspect pump reservoir for proper fluid level.

Inspect pump belt for proper tension.

Inspect pump driver pulley condition. 1. Place a container under the pump to catch the fluid
when disconnecting or connecting the hoses.
2. With the engine NOT running, disconnect the
pressure hose at the power steering pump and install
power steering tester J-29877-A. The gage must be
between the shutoff valve and pump. Open the
shutoff valve.
3. Check the fluid level. Fill the reservoir with power
steering fluid, to the ªFullº mark. Start the engine,
then turn the steering wheel and momentarily hold it
against a stop (right or left). Turn the engine off and
check the connections at tester for leakage.

1. Turn the steering wheel so that the vehicle's wheels
are pointing straight ahead.
2. Turn the ignition switch to ªLOCKº.
3. Disconnect the battery ª±º terminal cable, and wait at
least 5 minutes.
4. Disconnect the yellow 2-way SRS connector located
under the steering column.
5. Loosen the inflator module fixing bolt from behind the
steering wheel assembly using a TORX) driver or
equivalent until the inflator module can be released
from steering assembly .

Inspection and Repair
WARNING: T H E I N F L AT O R M O D U L E S H O U L D
ALWAYS BE CARRIED WITH THE TRIM COVER
AWAY FROM YOUR BODY AND SHOULD ALWAYS
BE LAID ON A FLAT SURFACE WITH THE
URETHANE SIDE UP. THIS IS NECESSARY
BECAUSE FREE SPACE IS PROVIDED TO ALLOW
THE AIR CUSHION TO EXPAND IN THE UNLIKELY
EVENT OF ACCIDENTAL DEPLOYMENT.
OTHERWISE, PERSONAL INJURY MAY RESULT .

The inflator module consists of a cover, air bag, inflator,
and retainer. Inspect the inflator module mainly for the
following:

Check for holes, cracks, severe blemishes and
deformation on the cover.

Check that the retainer is not deformed.

Check for defects such as damage and breakage in
the lead wire for the igniter.
Replace the inflator module if a defect is found during
inspection.
Installation
1. Install inflator module.
2. Support the module and carefully connect the module
connector and horn lead.
NOTE: Pass the lead wire through the tabs on the plastic
cover (wire protector) of inflator to prevent lead wire from
being pinched.
3. Tighten bolts to specified torque.
Torque: 9 N´m (78 lb in)
4. Connect the yellow 2-way SRS connector located
under the steering column.
5. Connect the battery ª±º terminal cable.
6. Set ignition to ªONº while watching warning light.
Light should flash 7 times and then go off. If lamp
does not operate correctly, refer to
Restraints section.

CAUTION: Once the steering column is removed
from the vehicle, the column is extremely
susceptible to damage. Dropping the column
assembly on its end could collapse the steering shaft
or loosen the slide block which maintains column
rigidity. Leaning on the column assembly could
cause the jacket to bend or deform. Any of the above
damage could impair the column's collapsible
design. If it is necessary to remove the steering
wheel, use only the specified steering wheel puller.
Under no conditions should the end of the shaft be
hammered upon, as hammering could loosen the
slide block which maintains column rigidity.Removal
1. Turn the steering wheel so that the vehicle's wheels
are pointing straight ahead.
2. Turn the ignition switch to ªLOCKº.
3. Disconnect the battery ground cable, and wait at least
5 minutes.
4. Disconnect the yellow 2-way SRS connector located
under the steering column.

Installation
1. Install steering wheel by aligning the setting marks
made when removing.
CAUTION: Never apply force to the steering wheel
shaft using a hammer or other impact tools in an
attempt to remove the steering wheel. The steering
shaft is designed as an energy absorbing unit.
2. Tighten the steering wheel fixing nut to the specified
torque.
Torque: 34 N´m (25 lb ft)
3. Connect horn lead.
4. Support the module and carefully connect the SRS
connector.
NOTE: Pass the lead wire through the tabs on the plastic
cover (wire protector) of inflator to prevent lead wire from
being pinches.
5. Tighten bolts to specified torque.
Torque: 9 N´m (78 lb in)
6. Connect the yellow 2-way SRS connector located
