Caution: Proper operation of the 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 in a collision
or deployment for conditions less severe than intended.
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.
| • | 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. |
| • | 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 Inflator Module Deployment - Component Replacement and Inspections
After a collision involving frontal air bag deployment, replace the following
components.
| • | Inflatable restraint I/P module |
| • | Inflatable restraint steering wheel module |
| • | Inflatable restraint sensing and diagnostic module (SDM) |
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 I/P module, steering wheel
module, and SDM - Inspect for damage and repair or replace each component
as needed. |
