2. To reinstall the connector, push it into position until

it clicks, then close its lid.
Precautions/Procedures

Inspection After Deployment

After a collision in which the airbags were deployed,

replace the deployed parts (airbag, seat belt tensioner

and side airbag), the SRS unit, the side impact sensor on

the side which deployed, and any related parts, and

inspect the following:

1. Inspect all the SRS wire harnesses. Replace, don't

repair, any damaged harnesses.

2. Inspect the cable reel for heat damage. If there is any

damage, replace the cable reel.

3. After the vehicle is completely repaired, turn the igni-

tion switch on. If the SRS indicator light comes on

for about 6 seconds and then goes off, the SRS sys-

tem is OK. If the indicator light does not function

properly, go to SRS Troubleshooting.

Disconnecting the SRS Connector

at the Fuse Box - '96 - 98 Models

CAUTION: Avoid breaking the connector; it's double-

locked.

1. First lift the connector lid with a thin screwdriver,

then press the connector tab down and pull the con-

nector out.
Wiring Precautions

• Never attempt to modify, splice or repair SRS wiring.

NOTE: SRS wiring harnesses are indicated by yellow

color.

• Be sure to install the harness wires so that they are not

pinched or interfering with other parts.

• Make sure all SRS ground locations are clean and

grounds are securely fastened for optimum metal-to-

metal contact. Poor grounding can cause intermittent

problems that are difficult to diagnose.ProCarManuals.com
