Component Inspection

Repairs and Inspections Required after an Accident of Air Bag System

CAUTION:
- All air bag system components, including the electrical harness (component mounting points), must be inspected after an accident. If any components are damaged or bent, they must be replaced even if air bag system activation did not occur.
- Never use air bag system parts from another vehicle.
- Do not attempt to service the parts. Service of these parts is by replacement only.
- Driver/Passenger air bag (inflator) modules, Driver/Passenger seat belt pretensioners
- Forward sensors
- SDM
- Contact coil and combination switch assembly
- Air bag wire harness

- Proper operation of the sensors and air bag system requires that any repairs to the vehicle structure return it to its original production configuration.

CAUTION: After detecting one time of such collision as to meet deployment conditions, the SDM must not be used. Refer to "Air Bag Diagnostic System Check" when checking the SDM.

Accident with or without Deployment/Activation - Component Inspections
Certain air bag and restraint system components must be inspected after any crash, whether the air bag system activated or not. If any faulty condition is found in the following checks, replace faulty part.

Those components are:
- Steering column and shaft joints
- Check for length, damage and bend according to "Checking Steering Column for Accident Damage:




- Steering column bracket and capsules
- Check for damage and bent.




- Steering wheel and driver air bag (inflator) module
- Check for damage or air bag (inflator) module fitness.
- Check trim cover (pad surface) for cracks.
- Check wire harness and connector for damage or tightness.




- Contact coil and combination switch assembly
- Check wire harness and connectors for damage or tightness.
- Check contact coil case for damage.




- Instrument panel member, reinforcement and knee bolster and panel (1) (driver and passenger)
- Check for any distortion, bending, cracking or other damage.




- Passenger air bag (inflator) module Check for dents, cracks, damage or fitness.
- Check trim cover for cracks or deformities.
- Check harness and connector for damage or tightness.




- SDM
- Check for external damage such as deformation, scratch, crack, peeled paint, etc.
- Check that SDM cannot be installed properly due to a cause in itself. (There is a gap between SDM and SDM plate, or it cannot be fixed securely.)
- Check that connector or lead wire of SDM has a scorching, melting or damage.
- Check SDM connector and terminals for tightness.
- Check SDM sets a DTC and the diagnostic flow leads to a malfunctioning SDM.




- Air bag wire harness and connections
- Check for damages, deformities or poor connections. Refer to "Inspection of intermittent and Poor Connections".
- Check wire harness clamps for tightness.




- Forward sensor
- Check sensor (1), sensor bracket (2), and front panel (3) for damage bend or rust.
- Check that connector (4) or lead wire (5) of forward sensor has a scorching, melting or damage.




- Seat belt pretensioner
- Check for dents, cracks, damage or fitness
- Check harness and connector for damage or tightness.

- Seat belts and mounting points
- Refer to "Seat Belt Inspection".

- "AIR BAG" warning lamp
- After vehicle is completely repaired, perform "Air Bag Diagnostic System Check".
