Component Inspection

Repairs and Inspections Required after An Accident

WARNING: Any repairs to the vehicle's structure must return it to the original production configuration. Deployment requires replacement of SDM, the inflator modules and a dimensional inspection of the steering column.

- If any SIR components are damaged, they must be replaced. If SIR components mounting points are damaged, they must be repaired or replaced.
- Never use SIR parts from another vehicle. This does not include remanufactured parts purchased from an authorized source.
- Do not attempt to service the SDM, the clock spring or other airbag modules, these items must be replaced if they are defective.
- Verify the part number of replaced airbag modules. Some inflator modules look identical but contain different internal components.

Accident with Deployment Components Replacements

All SIR components must be replaced after frontal crash involving airbag deployment. After deployment, a powdery residue may be on the surface of the airbag. The powder consists primarily of cornstarch (used to lubricate the bag as it inflates) and by-products of the chemical reaction. The sodium hydroxide then quickly reacts with atmospheric moisture and is converted to sodium bicarbonate (also known as baking soda). Therefore, it is unlikely that sodium hydroxide will be present after deployment. Replace the following SIR components.

WARNING: Wear gloves and safely glasses during the disposal procedure. Refer to Deployed Airbag Module Disposal Procedure.

- The SDM
- Airbag modules and pretensioners
- SIR wiring
- Clock spring

Accident without Deployment Component Inspection

Certain inspection must be performed after any crash, whether the airbag has deployed or not.:
- The steering column must be dimensionally inspected.
- Inspect the knee bolsters and mounting points for distortion, bending and cracking or other damages.
- Inspect the instrument panel (I/P) and steering column reinforcement plate for distortion, bending and cracking or other damage.
- Inspect the I/P braces for distortion, bending and cracking or other damage.
- Inspect the seat belt and mounting points. Refer to Driver Seat Belt Warning Circuit Diagnosis.
