Chevrolet Cobalt Service & Repair Manual: Collision Inspection
Accident Regardless of Air Bag Deployment
| Proper operation of Supplemental
Inflatable Restraint (SIR) sensing system requires that any repairs to vehicle
structure return vehicle structure to original production configuration.
Not properly repairing vehicle structure could cause non-deployment of air
bag(s) in a frontal collision or deployment of air bag(s) for conditions
less severe than intended. |
| After any collision, inspect following
components as indicated. If you detect any damage, replace component. If
you detect any damage to mounting points or mounting hardware, repair component
or replace hardware as required. |

Inspect steering column for bending,
twisting, buckling or any type of damage. |
| 2. |
Inspect knee bolsters for bending,
twisting, buckling or any other type of damage. |
| 3. |
Inspect instrument panel brackets and
brace for bending, twisting, buckling or any other type of damage. |

inspection. |
| 5. |
Inspect instrument panel cross vehicle
beam for bending, twisting, buckling or any other type of damage. |
| 6. |
Inspect instrument panel mounting points
and brackets for bending, twisting, buckling or any other type of
damage. |
| 7. |
Inspect seats and seat mounting points
for bending, twisting, buckling or any other type of damage. |

Impact Sensor Replacement Guidelines
| The impact sensor replacement
policy requires replacing sensors in area of accident damage. Area of accident
damage is defined as portion of vehicle which is crushed, bent or damaged
due to a collision. An example of this would be a moderate collision where
front of vehicle impacts a object. If vehicle has an impact sensor mounted
forward of radiator, it must be replaced. |
| 1. |
Replace impact sensor whether or not
air bags have deployed. |
| 2. |
Replace impact sensor even if it appears
to be undamaged. |
| 3. |
Impact sensor damage which is not visible,
such as slight bending of mounting bracket or cuts in wire insulation,
can cause improper operation of SIR system. Do not try to determine
whether impact sensor is undamaged, replace impact sensor. Also,
if DTC indicates a fault impact sensor, replace impact sensor. |
