avoid non-deployment in a collision, resulting in possible personal
injury.

WARNING:

Never probe the connectors on the airbag

module. Doing so can result in airbag deployment, which can result in
personal injury.

WARNING:

The safety belt buckle pretensioner is a

pyrotechnic device. Never probe a pretensioner electrical connector.
Doing so could result in pretensioner or airbag deployment and could
result in personal injury.

WARNING:

Never probe the electrical connector on a side

airbag module. Doing so can result in side airbag deployment.

NOTE:

Diagnostics or repairs are not to be performed on a seat

equipped with a seat side airbag with the seat in the vehicle. Prior to
attempting to diagnose or repair a seat concern when equipped with a seat
side airbag, the seat must be removed from the vehicle and the restraint
system diagnostic tools must be installed in the seat side airbag electrical
connectors. The restraint system diagnostic tools must be removed
prior to operating the vehicle over the road.

NOTE:

After diagnosing or repairing an SRS, the restraint system

diagnostic tools must be removed before operating the vehicle over
the road.

NOTE:

After diagnosing or repairing a seat system, the restraint system

diagnostic tools must be removed before operating the vehicle over
the road.

NOTE:

The SRS must be fully operational and free of faults before

releasing the vehicle to the customer.

Key in OFF position.

Deactivate the system. Refer to Airbag and Safety Belt Pretensioner
Supplemental Restraint System (SRS) in the Diagnosis and Testing
portion of this section.

Inspect the first row passenger side impact sensor mounting and
make sure that the retaining bolts are fully seated and tightened
correctly.

Remove the first row passenger side impact sensor.

Visually inspect the first row passenger side impact sensor, mounting
bracket and mounting surface for damage, corrosion or dirt.

Was a significant amount of corrosion or dirt found, the first row
passenger side impact sensor mounting bracket attached to the
mounting surface incorrectly or were the impact sensor bolts not
fully seated and tightened correctly?
