Repair and Inspection Required after AccidentS7RS0B8204049
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 below. Service of these parts is by replacement
only.
– Driver / Passenger air bag (inflator) modules
– Driver / Passenger side-air bag (inflator) modules
– Driver / Passenger side curtain-air bag (inflator) modules
– Driver / Passenger seat belt pretensioners
–Forward-sensor
– Driver / Passenger side-sensors
–SDM
– Contact coil and combination switch assembly
– Air bag wire harness in main harness, instrument panel harness and floor
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 Deployment / Activation – Component
Replacement
When driver and passenger air bags are deployed, the
following components must be replaced.
• Driver and passenger air bag (inflator) modules
• Driver and passenger seat belt pretensioners
• SDM after detecting such collision as to meet
deployment conditions
• Forward-sensor
• Instrument panel When side-air bag and side curtain-air bag are deployed,
the following components must be replaced.
• Deployed side-air bag (inflator) module
• Deployed side curtain-air bag (inflator) module
• Side-sensor
•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 faul
ty 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.
