Repairs and Inspections Required After an Accident
REPAIRS AND INSPECTIONS REQUIRED AFTER AN ACCIDENTCAUTION:
- 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 a deployment did not occur.
- Never use air bag system parts from another vehicle.
Do not attempt to service the parts below. Service of these parts is by replacement only.
- Driver/Passenger air bag (inflator) module
- 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 5DM must not be used.
ACCIDENT WITH DEPLOYMENT
COMPONENT REPLACEMENT
Certain air bag system components must be replaced. Those components are:
Driver and passenger air bag (inflator) modules.
- Replace with new one.
SDM after detecting such collision as to meet deployment conditions.
- Replace with new one.
ACCIDENT WITH OR WITHOUT DEPLOYMENT
COMPONENT INSPECTIONS
Certain air bag and restraint system components must be inspected after any crash, whether the air bag deployed or not. Those components are:
Steering column and shaft joints.
- Check for length, damage and bend.
Steering column bracket.
- Check for damage and bend. If any, replace.
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.
If any faulty condition is found in above checks, replace faulty part.
Contact coil & combination switch assembly.
- Check wire harness and connectors for damage or tightness.
- Check contact coil case for damage.
If any faulty condition is found in above checks, replace.
Instrument panel member, reinforcement and knee bolster & panel (driver and passenger).
- Check for any distortion, bending, cracking or other damage.
If any damage, repair or replace.
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.
If any damage or tightness, repair or replace.
SDM and SDM bracket.
- Check for external damage such as deformation, scratch, crack, peeled paint, etc..
- Check whether SDM can installed properly due to a cause in itself. (There is a gap between SDM and SDM bracket, or it cannot be fixed securely.)
- Check whether connector or lead wire of SDM has a scorching, melting or damage.
- Check whether connector can be connected securely or locked.
- Check SDM connector and terminals for tightness.
- Check SDM sets a diagnostic trouble code and the diagnostic chart leads to a malfunctioning SDM.
If any faulty condition is found in above checks, replace.
Air bag wire harness and connections.
- Check for damages, deformities or poor connections. Refer to "Intermittents and Poor Connections" in this section.
- Check wire harness clamps for tightness.
If any faulty condition is found, correct or replace.
Seat belts and mounting points.
"AIR BAG" warning lamp (air bag system).
After vehicle is completely repaired, perform "Air Bag Diagnostic System Check" described in diagnosis section.
