Repairs and Inspections Required After a Collision: Service and Repair
Air Bag System
Accident With Air Bag Deployment
After a collision involving air bag deployment, replace the following components.
^
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 IP module, steering wheel module, and SDM - Inspect for any damage and repair or replace each
component as needed.
^
Inspect the components indicated above in Accident With or Without Air Bag Deployment.
Accident Without Air Bag Deployment
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.
^
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 any collision, inspect the following components as indicated. If you detect any damage, replace the component. It you detect any damage to the
mounting points or mounting hardware, 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 Standard or Steering Column Accident Damage Inspection - Off Vehicle in Steering Wheel and Column -
Tilt.
^
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. See: Seat Belt
Systems/Testing and Inspection/Initial Inspection and Diagnostic Overview/Operational and Functional Checks
^
Seats and Seat Mounting Points-Inspect for bending, twisting, buckling, or any other type of damage.
Sensor Replacement Guidelines
The SIR 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. For example, a moderate collision where the front of the vehicle impacts a tree. If the
vehicle has an SIR sensor mounted forward of the radiator, it must be replaced.
^
Replace the sensor whether or not the air bags have 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. Also, if you follow a Diagnostic Trouble Code (DTC)
table and a malfunctioning sensor is indicated, replace the sensor.
