REPAIRS AND INSPECTIONS REQUIRED AFTER A COLLISION

Accident With or Without Inflator Module Deployment - Component Inspections 

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. 

z

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

z

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

z

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

z

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

z

The I/P cross car beam - Inspect for bending, twisting, buckling, or any other type of damage.  

z

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

z

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

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 to 
the mounting points or mounting hardware, repair or replace the mounting points and mounting hardware as 
needed. 

z

Inflatable restraint I/P module  

z

Inflatable restraint steering wheel module  

z

Inflatable restraint steering wheel module coil  

z

Inflatable restraint sensing and diagnostic module (SDM)  

z

Inflatable restraint electronic frontal sensor (EFS)  

Perform additional inspections on the following components. 

z

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

z

Mounting points or mounting hardware for the I/P module, steering wheel module, SDM, and EFS sensor 
- Inspect for any damage and repair or replace each component as needed. 

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.

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 radiator, replace the SIR sensor. 

z

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

z

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. 

INFLATOR MODULE HANDLING AND SCRAPPING 

Live (Undeployed) Inflator Modules 

CAUTION: Refer to SIR Inflator Module Handling and Storage Caution in Cautions and 

Notices.
