• Improperly formed or damaged terminals.
Check each connector terminal in problem circuits
carefully to ensure good contact tension by using the
corresponding mating terminal included in the
connector test adapter kit (special tool).
If contact tension is not enough, reform the terminal to
increase contact tension or replace it.

• Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor
connection by shaking it by hand lightly. If any
abnormal condition is found, change the wire harness
assembly or component parts with new ones.
• Wire insulation which is rubbed through, causing an
intermittent short as the bare area touches other
wiring or parts of the vehicle.
• Wire broken inside the insulation. This condition could
cause a continuity check to show a good circuit, but if
only 1 or 2 strands of a multi-strand-type wire are
intact, resistance could be far too high.
Repair and Inspection Required after AccidentS6RW0D8204048
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 impact-sensor
– Driver / Passenger side impact-sensors
–SDM
– Contact coil and combination switch
assembly
– Air bag wire harness in main harness,
instrument panel harness, floor harness,
passenger air bag harness, side-air bag
harness and side curtain-air bag
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 impact-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 impact-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 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.
– Check SDM for a cause in itself preventing its
proper installation. (There is a gap between SDM
and SDM plate, or it cannot be fixed securely.)

sensor for scorching, melting or damage.• Side impact-sensor
– Check sensor (1) and under body (2) for dents,
cracks, deformation or rust.
– Check sensor connector (sensor side and harness
side) (3) or sensor lead wire (4) for damage, crack,
scorching or melting.
• 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 “Front Seat Belt Components in Section
8A”.
• “AIR BAG” warning light
– After vehicle is completely repaired, perform “Air
Bag Diagnostic System Check”.
• Side-air bag (inflator) module
– Check for dents, cracks, damage or fitness.
– Check trim cover for cracks or deformities.
– Check wire harness and connector for damage or
tightness.
• Side curtain-air bag (inflator) module
– Check for dents, cracks, damage or fitness.
