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 any collision, inspect the following components as indicated. If damage
is detected, replace the component. If damage to the mounting points or mounting
hardware is detected, repair the component or replace the 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. |
| • | I/P Cross Car Beam -- Inspect for bending, twisting, buckling, or
any other type of damage. |
| • | I/P Mounting Points and Brackets -- 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. |
Frontal Inflator Module Deployment - Component Replacement and Inspections
After a collision involving inflator module deployment, replace the following
components.
| • | Inflatable restraint I/P module |
| • | Inflatable restraint sensing and diagnostic module (SDM). Replace only
if DTC B0051 or DTC B0053 cannot be cleared using the scan tool. Refer
to
DTC B0051
or
DTC B0053
. |
| • | Inflatable restraint steering wheel module |
| • | Inflatable restraint seat belt pretensioners |
Perform additional inspections on the following components:
| • | Inflatable restraint steering wheel module coil and coil wiring pigtail --
Inspect for melting, scorching, or other damage due to excessive heat. |
| • | Mounting point or mounting hardware for the I/P module, steering wheel
module, and SDM -- Inspect for any damage and repair or replace each component
as needed. |
Roof Rail Inflator Module Deployment - Component Replacement and Inspections
After a collision involving a roof rail inflator module deployment, replace
the following components on the side of the impact.
| • | Inflatable restraint seat belt pretensioners |
| • | Inflatable restraint roof rail modules, Left/Right, on the side of the
impact |
| • | Inflatable restraint sensing and diagnostic module (SDM) |
| • | Inflatable restraint side impact sensor (SIS), Left/Right, on the side
of the impact |
Perform additional inspections on the following components.
| • | Mounting points or mounting hardware for the inflatable restraint SIS
on the side of the impact -- Inspect for any damage and repair or replace each
component as needed. |
| • | Mounting points or mounting hardware for the inflatable restraint SDM
and seat belt pretensioners -- Inspect for any damage and repair or replace each
component as needed. |
Sensor Replacement Guidelines
The SIS 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.
| • | 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 a slight bending of the mounting
bracket or cuts in the wire insulation, can cause improper operation of the sensor.
Do not try to determine whether the sensor is undamaged. Replace the sensor.
