•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 (1) and shaft joints
– Check for length, damage and bend according to
“Checking Steering Column for Accident Damage in
Section 6B”.
• Steering column bracket (2) 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 assembly
– Check wire harness and connectors for damage or
tightness.
– Check contact coil case for damage.
– Check contact coil circuit referring to “Contact Coil
Cable and Its Circuit Check”.
• Instrument panel member and reinforcement
– Check for any distortion, bending, cracking or other
damage.
– Check instrument panel for cracks or deformities.
• Passenger air bag (inflator) module
– Check for dents, cracks, damage or fitness.
– Check harness and connector for damage or
tightness.
•SDM
– Check for external damage such as deformation,
scratch, crack, peeled paint, etc.
