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 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 the component or replace the hardware as needed.

After a collision involving seat belt side buckle pretensioner deployment and frontal 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.

After a collision involving frontal air bag deployment, inspect the Inflatable restraint steering wheel module coil and the coil wiring pigtail for melting, scorching, or other damage due to excessive heat. Perform this component inspection in addition to the inspections indicated above in Accident With or Without Air Bag Deployment. If you detect any damage, replace the component. If you detect any damage to the mounting points or mounting hardware, repair the component or replace the hardware as needed.

After a collision involving seat belt side buckle pretensioner 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.

If Current DTC 56 is set, the SDM must also be replaced. This is because the vehicle has been involved in 3 pretensioner-only deployment collisions, the maximum number of pretensioner-only deployments allowed with one SDM. Select Reset Pretensioner Devices from the SIR Data List using the scan tool to verify that the seat belt side buckle pretensioners have deployed 3 times.

After a collision involving a driver side 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.

After a collision involving driver side air bag deployment, inspect the LH front door harness, LH door seal and driver seat for cutting/chafing or other damage due to a side impact. Perform this component inspection in addition to the inspections indicated above in Accident With or Without Air Bag Deployment. If you detect any damage, replace the component. If you detect any damage to the mounting points or mounting hardware, repair the component or replace the hardware as needed.

If Current DTC 56 is set, the SDM must also be replaced. This is because the vehicle has been involved in 3 driver side air bag deployment collisions, the maximum number of driver side air bag deployments allowed with one SDM. Select and read Reset Driver Side Air Bag from the SIR Data List using the scan tool to verify that the driver side air bag has deployed 3 times.

After a collision involving a passenger side 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.

After a collision involving passenger side air bag deployment, inspect the RH front door harness, RH door seal and driver seat for cutting/chafing or other damage due to a side impact. Perform this component inspection in addition to the inspections indicated above in Accident With or Without Air Bag Deployment. If you detect any damage, replace the component. If you detect any damage to the mounting points or mounting hardware, repair the component or replace the hardware as needed.

If Current DTC 56 is set, the SDM must also be replaced. This is because the vehicle has been involved in 3 passenger side air bag deployment collisions, the maximum number of passenger side air bag deployments allowed with one SDM. Select and read Reset Passenger Side Air Bag from the SIR Data List using the scan tool to verify that the passenger side air bag has deployed 3 times.

The SIR sensor replacement policy requires replacing inflatable restraint side impact 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 a SIR sensor mounted forward of the radiator, it must be replaced.

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.
