Airbag

Replacement

After a collision in which the airbags were deployed, the

airbag assemblies and the SRS unit must be replaced.

Store a removed airbag assembly with

the pad surface up. If the airbag is improperly stored

face down, accidental deployment could propel the unit

with enough force to cause serious injury.

CAUTION:

Always disconnect the airbag connectors when the

SRS main harness is disconnected.

'96 Model: Always keep the short connector (RED) on

the passenger's airbag when the harness is discon-

nected.

Do not disassemble or tamper with the airbag.

NOTE:

Do not install used SRS parts from another vehicle.

When repairing, use only new SRS parts.

Carefully inspect the airbag before you install it. Do

not install an airbag that shows signs of being

dropped or improperly handled, such as dents, cracks

or deformation.

1. Make sure you have the anti-theft code for the radio,

then write down the frequencies for the radio's pre-

set buttons.

2. Disconnect the battery negative cable, then discon-

nect the positive cable from the battery, and wait at

least three minutes.

3. Disconnect the airbag connectors:

Driver's Side:

Remove the access panel from the steering wheel,

then disconnect the 2P connector between the driver's

airbag and cable reel.

Disconnect the 3P connector between the front pas-

senger's airbag and SRS main harness, then connect

the short connector (RED) to the airbag side of the con-

nector.

with a flat tip screwdriver.
