DESCRIPTION & OPERATION

WARNING: Vehicle is equipped with a Supplemental Restraint System

(SRS) that includes an air bag located in steering wheel.

Use caution when working around steering column. Ensure

battery is disconnected before attempting any repair. DO NOT

apply electrical power to any component on steering column

without disconnecting air bag module (air bag could deploy).

Steering column consists of a collapsible steering shaft with

lower joint assembly. Vehicle is equipped with a Supplemental

Restraint System (SRS) that includes an air bag and clockspring

located in steering column wheel.

NOTE: For information not covered in this article, air bag

DIAGNOSIS & TESTING or DISPOSAL PROCEDURES, see AIR BAG

RESTRAINT SYSTEM article.

DISABLING & ACTIVATING AIR BAG SYSTEM

WARNING: Wait at least 60 seconds after disconnecting negative

battery cable before servicing SRS. System reserve capacitor

maintains SRS voltage for about 60 seconds after battery is

disconnected. Servicing SRS before 60-second period may

cause accidental air bag deployment and possible personal

injury.

To disable system, turn ignition switch to OFF position.

Disconnect and isolate negative battery cable end. Wait at least 60

seconds. To activate system, reconnect negative battery cable.

AIR BAG SERVICE PRECAUTIONS

The following precautions should be observed when working

with SRS:

* Disable SRS before servicing any SRS or steering column

component. Failure to do this may result in accidental air

bag deployment and possible personal injury. See DISABLING &

ACTIVATING AIR BAG SYSTEM.

* Wait at least 60 SECONDS after disabling air bag system. SRS

system retains enough voltage, for a short time after system

is disabled, to deploy air bag.

* After repairs, always turn ignition on to ensure SRS warning

light is working properly and no system faults are indicated.

* Always wear safety glasses when servicing or handling an air

bag.

* DO NOT expose air bag module and clockspring to temperatures

more than 200 F (93 C).

* When placing a live air bag on a bench or other surface,

always face air bag and trim cover up, away from surface.

This will reduce motion of module if air bag accidentally

deploys.

* After air bag deploys, air bag surface may contain deposits

of sodium hydroxide, which irritate skin. Always wear safety

glasses, rubber gloves and long-sleeved shirt during clean

up. Wash hands using mild soap and water. Follow correct

clean-up and disposal procedures.

* Because of critical system operating requirements, DO NOT

service any SRS components. Repairs are only made by

replacing defective part(s).

* DO NOT allow any electrical source near inflator on the back

of air bag module.

* When carrying live air bag module, trim cover should be

pointed away from body to minimize injury in case of

accidental air bag deployment.

* If SRS is not fully functional for any reason, DO NOT drive

vehicle until system is repaired and is fully functional. DO

NOT remove bulbs, modules, sensors or other components, or in

any way disable system from operating normally. If SRS is not

functional, park vehicle until repairs are made.

REMOVAL & INSTALLATION

STEERING WHEEL

WARNING: Wait at least 60 seconds after disconnecting negative

battery cable before servicing SRS. System reserve capacitor

maintains SRS voltage for about 60 seconds after battery is

disconnected. Servicing SRS before 60-second period may

cause accidental air bag deployment and possible personal

injury.

Removal

Disable air bag. See DISABLING & ACTIVATING AIR BAG SYSTEM.

Ensure steering wheel is straight ahead. Remove air bag. Place

reference mark on steering wheel and steering column shaft for

installation reference. Remove steering wheel nut and washer. Using

steering wheel puller, remove steering wheel.

CAUTION: DO NOT hammer on steering wheel during removal or

installation, as it may damage steering column.

Installation

To install, reverse removal procedure. Ensure reference marks

are aligned. Tighten fasteners to specification. See

TORQUE SPECIFICATIONS. Activate air bag. See DISABLING & ACTIVATING

AIR BAG SYSTEM.

COMBINATION SWITCH

CAUTION: When installing steering wheel, if rotating part of

clockspring is not properly centered with steering column

and front wheels, clockspring failure will result.

Removal & Installation

Remove lower instrument cover and lower heater duct. Remove

air bag and steering wheel. See STEERING WHEEL under

REMOVAL & INSTALLATION. Remove upper and lower steering column covers.

Disconnect clockspring electrical connector. Remove screws attaching

colckspring and remove clockspring. Disconnect combination switch

electrical connectors. Remove screws and combination switch. To

install, reverse removal procedure.

assembly.

2) To install, reverse removal procedure. Tighten new bolts

until heads of bolts sheer off.

STEERING COLUMN

WARNING: Failure to follow air bag service precautions may result in

air bag deployment and personal injury. See AIR BAG SERVICE

PRECAUTIONS. Follow all service precautions before

attempting repairs. After component replacement, perform a

system operational check to ensure proper system operation.

CAUTION: Applying excessive pressure or causing impact to steering

shaft during service may cause column to collapse. Before

removing steering column, ensure wheels are in

straight-ahead position. Note steering wheel location for

installation reference.

Removal

1) Remove steering wheel. Remove combination switch and

ignition switch (if necessary). See STEERING WHEEL under

REMOVAL & INSTALLATION.

2) Remove lower instrument panel cover and air duct.

Disconnect all electrical connections. Disconnect brake pedal return

specification. See TORQUE SPECIFICATIONS.

OVERHAUL

STEERING COLUMN

WARNING: Failure to follow air bag service precautions may result in
