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 (5DM)
