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.
– Check wire harness and connector for damage or tightness.

The adapter (1) will also give an idea of whether or not
contact tension is sufficient, helping to find an open or
intermittent open due to poor terminal contact. An SDM
short bar release tool (2) is included in the connector test
adapter kit. Inserting it in to the SDM connector (3) will
releases the shorting bar.
Special tool
(B): 09932–75010 Air bag driver / passenger load
tool
This tool is used as a diagno stic aid and safety device to
prevent inadvertent air bag (inflator) module deployment.
The load tool has three connectors attached to its case
which are electrically functional and serve as resistive
load substitutions.
No more than two connectors are used at any time.
One of connectors (“STEER ING WHEEL”) is used to
substitute the load of the followings.
• Driver air bag (inflator) module when it is connected at the top of the column to the contact coil assembly.
• Passenger air bag (inflator) module when it is connected to the air bag harness connector in
instrument panel harness for passenger air bag
(inflator) module.
• Each of driver and passen ger seat belt pretensioners
when it is connected to air bag harness connector in
instrument panel harness for driver and passenger
seat belt pretensioners.
• Side-air bag (inflator) module when it is connected to the floor harness connector for side-air bag (inflator)
module.
• Side curtain-air bag (inflator) module when it is connected to the floor harness connector for side
curtain-air bag (inflator) module. Another connec
tor (“BASE OF COLUMN ”) is used to
substitute the load of the driver air bag (inflator) module
and the contact coil assembly when it is connected at the
base of the column to the air bag wire harness.
The third connector (“PASSENGER INFLATOR”) is not
used.
By substituting the resistan ce of the load tool when
called for, a determination can be made as to whether an
inflator circuit component is causing system malfunction
and which component is causing the malfunction.
The load tool should be used only when specifically
called for in the diagnostic procedures.
