REPAIRS AND INSPECTIONS REQUIRED AFTER A COLLISION

Accident With or Without Inflator Module Deployment - Component Inspections

Fastener Tightening Specifications: Refer to Fastener Tightening Specifications.

Preliminary Procedure

1. Disable the SIR. Refer to SIR Disabling and Enabling.

2. Remove the center pillar lower trim panel. Refer to Center Pillar Lower Trim

Panel Replacement .

3. Fully deploy the pretensioner before disposal. Refer to Pretensioner Handling and

Scrapping.

Make sure the open end of the seat belt pretensioner piston tube points away from you and
other people.

Do not cover the seat belt pretensioner piston tube opening with your hand.

Failure to observe these guidelines may result in personal injury.

After any collision, inspect the following components as indicated. If you detect any damage,
replace the component. If you detect any damage to the mounting points or mounting hardware,
repair or replace the mounting points and mounting hardware as needed.

The steering column-Perform the steering column accident damage checking procedures.
Refer to Steering Column Accident Damage Inspection .

The instrument panel (I/P) knee bolsters and mounting points-Inspect the knee bolsters for
bending, twisting, buckling or any other type of damage.

The I/P brackets, braces, etc.-Inspect for bending, twisting, buckling or any other type of
damage.

The seat belts-Perform the seat belt operational and functional checks. Refer to
Operational and Functional Checks .

The I/P mounting points and brackets-Inspect for bending, twisting, buckling or any other
type of damage.

The roof rail and roof rail module mounting points-Inspect for bending, twisting, buckling
or any other type of damage.

The seats and seat mounting points-Inspect for bending, twisting, buckling or any other type
of damage.

Passenger seat bottom equipped with Passenger Presence System (PPS)-Check for any
DTCs or problems that may cause the PPS not to function properly.

Accident With Frontal Air Bag Deployment - Component Replacement and Inspections

After a collision involving air bag deployment, replace the following components. If you detect
any damage, replace the component. If you detect any damage to the mounting points or mounting
hardware, repair or replace the mounting points and mounting hardware as needed.

Inflatable restraint front end sensors

Inflatable restraint I/P module, if deployed and after performing the necessary inspections

collision or deployment for conditions less severe than
intended.

IMPORTANT: The front passenger seat is equipped with a PPS, which detects

an occupant. If the requirements for disabling the I/P air bag are
met then the PPS will communicate with the SDM to disable/turn
off the I/P air bag, even in a accident. For more information on the
PPS refer to SIR System Description and Operation.

listed above

Inflatable restraint sensing and diagnostic module (SDM)

Inflatable restraint steering wheel module

Inflatable restraint steering wheel module coil

Seat belt pretensioners

Perform additional inspections on the following components:

Steering wheel module coil and the coil wiring pigtail-Inspect for melting, scorching or
other damage due to excessive heat.

Mounting points or mounting hardware for the I/P module, steering wheel module, SDM,
front end sensors, seat belt pretensioners and vehicle rollover sensor-Inspect for any damage
and repair or replace each component as needed.

Passenger Presence System (PPS) for damage to the wiring or pressure system

Accident With Side Air Bag Deployment - Component Replacement and Inspections

After a collision involving side air bag deployment, replace the following components:

Inflatable restraint roof rail module, on the side of the impact.

Inflatable restraint side impact sensors (SIS) (left/right), on the side of the impact

Inflatable restraint side impact module (left/right), on the side of the impact

Inflatable restraint SDM

Seat belt pretensioner, on the side of impact.

Perform additional inspections on the following components:

Mounting points or mounting hardware for the SIS, roof rail module (left/right) and seat
belt pretensioner on the side of impact-Inspect for any damage and repair or replace each
component as needed.

Mounting points or mounting hardware for the SDM and vehicle rollover sensor-Inspect for
any damage and repair or replace each component as needed.

Sensor Replacement Guidelines

The SIR/side air bag sensor replacement policy requires replacing sensors in the area of accident
damage. The area of accident damage is defined as the portion of the vehicle which is crushed,
bent or damaged due to a collision. An example of this would be a moderate collision where the
front of the vehicle impacts a tree, if the vehicle has an SIR sensor mounted forward of the

2007 Hummer H3

2007 RESTRAINTS Supplemental Inflatable Restraints - H3

radiator, replace the SIR sensor.

Replace the sensor whether or not the air bags have deployed.

Replace the sensor even if the sensor appears to be undamaged.

Sensor damage which is not visible, such as slight bending of the mounting bracket or cuts in the
wire insulation, can cause improper operation of the SIR/side air bag sensing system. Do not try
to determine whether the sensor is undamaged. Replace the sensor. Also, if you follow a
diagnostic trouble code (DTC) table and a malfunctioning sensor is indicated, replace the sensor.
