WIRING DIAGRAMS

STEERING COLUMN
1998 Mitsubishi Montero
1997-98 STEERING
Mitsubishi - Steering Columns - RWD & 4WD
Mitsubishi: Montero, Montero Sport
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 (93C).
* 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.
