SERVICE AFTER A SUPPLEMENTAL RESTRAINT SYSTEM DEPLOYMENT

Any vehicle which is to be returned to use following a Supplemental Restraint System (SRS) component deployment
must have the deployed restraints replaced. In addition, the following guidelines MUST be observed.
• Following ANY major vehicle impact damage in the vicinity of an impact sensor or the ORC - It is
critical that the mounting surfaces and mounting brackets for the Occupant Restraint Controller (ORC),
front impact sensors and side impact sensors located within the proximity of the impact damage be closely
inspected and restored to their original conditions. Because the ORC and each impact sensor are used by the
SRS to monitor or confirm the direction and severity of a vehicle impact, improper orientation or insecure
fastening of these components may cause airbags not to deploy when required, or to deploy when not
required.
• Following ANY airbag deployment event - The Lower Anchors and Tethers for CHildren (LATCH) provisions,
the upper tether anchors and all interior trim panels must also be inspected.
• If the driver airbag is deployed - If the Driver AirBag (DAB) has been deployed, the DAB, the clockspring
and stalk unit, the steering column assembly including the intermediate shaft and coupler, both front seat belt
anchor buckle tensioners, both front seat belt retractor and tensioner assemblies, any front seat belt buckle
in use and all rear seat belt retractors and buckles in use must be replaced. The front impact sensors and the
steering wheel must also be inspected.
• If the knee airbag is deployed - If the Knee AirBag (KAB) has been deployed, the KAB and the instrument
panel steering column opening cover must also be replaced. The instrument panel must also be inspected.
• If the passenger airbag is deployed - If the Passenger AirBag (PAB) has been deployed, the PAB, the PAB
wire harness or connector, and the instrument panel must be replaced.
• If a seat airbag is deployed - If a Seat AirBag (SAB) has been deployed, the SAB, the seat back frame, the
seat back foam, the seat back trim cover and the side impact sensor on the same side of the vehicle as the
deployed airbag must be replaced. Both front seat belt anchor buckle tensioners, both front seat belt retractor
and tensioner assemblies, any front seat belt buckle in use and all rear seat belt retractors and buckles in
use must be replaced.
• If a seat belt tensioner is deployed - The seat belt retractor and anchor latch plate tensioners are deployed
in conjunction with the front airbags. All seat belt tensioners must be replaced if any airbag in the vehicle
except the Knee AirBag (KAB) has been deployed.
• If a side curtain airbag is deployed - If a side curtain airbag (also known as a Side AirBag Inflatable Curtain/
SABIC) has been deployed, the SABIC, the trim on the upper A, B, C and D-pillars as well as the side impact
sensor on the same side of the vehicle as the deployed airbag must be replaced. The headliner, both front
seat belt anchor buckle tensioners, both front seat belt retractor and tensioner assemblies, any front seat belt
buckle in use and all rear seat belt retractors and buckles in use must be replaced.
The components identified with the deployed SRS components in the preceding list are not intended for reuse and
will be damaged or weakened as a result of an airbag deployment, which may or may not be obvious during a
visual inspection. All other vehicle components should be closely inspected following any SRS component
deployment, but are to be replaced only as required by the extent of the visible damage incurred.

DIAGNOSIS AND TESTING - SUPPLEMENTAL RESTRAINT SYSTEM

The hard wired circuits between modules and components related to the Supplemental Restraint System (SRS) may
be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The
wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness
routing and retention, connector pin out information and location views for the various wire harness connectors,
splices and grounds.
However, conventional diagnostic methods will not prove conclusive in the diagnosis of the SRS or the electronic
controls and communication between other modules and devices that provide features of the SRS. The most
reliable, efficient and accurate means to diagnose the SRS or the electronic controls and communication related to
SRS operation, as well as the retrieval or erasure of a DTC requires the use of a diagnostic scan tool. Refer to
the appropriate diagnostic information.
In addition to a diagnostic scan tool that contains the latest version of the proper diagnostic software, certain
diagnostic procedures for the SRS may require the use of the SRS Load Tool special tool along with the appropriate
Load Tool Jumpers and Adapters. Refer to the appropriate diagnostic information.
WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental
Restraint System (SRS) before attempting any steering wheel, steering column, airbags, airbag
curtains, knee blocker, seat belt tensioner, impact sensor or instrument panel component
