After a collision, the following components need to be inspected as indicated. If any damage is detected, replace the component. If damage to the mounting points or mounting hardware is detected, repair or replace the mounting points and mounting hardware as needed.

•	Steering column--Perform the steering column accident damage checking procedures. Refer to Steering Column Accident Damage Inspection - Off Vehicle in Steering Wheel and Column.

•	I/P Knee Bolsters and Mounting Points--Inspect the knee bolsters for bending, twisting, buckling, or any other type of damage.

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

•	Seat Belts--Perform the seat belt operational and functional checks. Refer to Operational and Functional Checks in Seat Belts.

•	Seats and Seat Mounting Points--Inspect for bending, twisting, buckling, or any other type of damage.

After inspecting the components listed above, proceed to the following Component Replacement and Inspections if air bag deployment has occurred.

Frontal Air Bag Deployment -- Component Replacement and Inspections

CAUTION: Proper operation of the Supplemental Inflatable Restraint (SIR) sensing system requires that any repairs to the vehicle structure return the vehicle structure to the original production configuration. Not properly repairing the vehicle structure could cause non-deployment of the air bag(s) in a frontal collision or deployment of the air bag(s) for conditions less severe than intended.

After a collision involving frontal air bag deployment, replace the following components.

•	Inflatable restraint electronic frontal sensor (EFS)

•	Inflatable restraint front end discriminating sensor

•	Inflatable restraint IP module

•	Inflatable restraint sensing and diagnostic module (SDM)

•	Inflatable restraint steering wheel module

Perform additional inspections on the following components.

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

•	Mounting points and mounting hardware for the EFS, front end discriminating sensor, IP module, steering wheel module, and SDM - Inspect for damage and repair or replace each component as needed.

Side Air Bag Deployment -- Component Replacement and Inspections

CAUTION: Proper operation of the Supplemental Inflatable Restraint (SIR) sensing system requires that any repairs to the vehicle structure return the vehicle structure to the original production configuration. Not properly repairing the vehicle structure could cause non-deployment of the side impact air bag(s) in a side impact collision or deployment of the side impact air bag(s) for conditions less severe than intended.

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

•	Inflatable restraint sensing and diagnostic module (SDM)

•	Inflatable restraint side impact module, on side of impact

•	Inflatable restraint side impact sensor (SIS), on side of impact

Perform additional inspections on the mounting points and mounting hardware for the side impact module, SIS, and SDM - Inspect for damage and repair or replace each component as needed.

SIR Sensor Replacement Guidelines

The SIR sensor replacement policy requires replacing sensors in the area of collision damage. The area of collision damage is defined as the portion of the vehicle which is crushed, bent, or damaged due to a collision.

•	Replace the sensor even if the air bags have not deployed.

•	Replace the sensor even if it 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 sensing system. Do not try to determine whether the sensor is undamaged, replace the sensor.
