• Never attempt disassembly of SDM.
• When storing SDM, select a place where neither high
temperature nor high humidity is anticipated and oil,
water and dust are kept off.
• If SDM has been dropped, replace it with a new one.
• If SDM installation part of floor was damaged, repair
that part completely before reinstallation.
• All SDM and mounting bracket fasteners must be
carefully torqued and the arrow must be pointed
toward the front of the vehicle to ensure proper
operation of the air bag system.
Live (Undeployed) Air Bag (Inflator) Modules
Special care is necessary when handling and storing a
live (undeployed) air bag (inflator) modules.
The rapid gas generation produced during deployment
of the air bag could cause the air bag (inflator) module,
or an object in front of the air bag (inflator) module, to be
thrown through the air in the unlikely event of an
accidental deployment.
WARNING!
Never attempt to measure the resistance of
the air bag (inflator) modules (driver module,
passenger module and side modules and
curtain modules). It is very dangerous as the
electric current from the tester may deploy
the air bag.

• Never attempt disassembly of the air bag (inflator)
modules.
• If any abnormality is found, be sure to replace it with
new one as an assembly.
• When an abnormality is noted as existing in the live
(undeployed) air bag (inflator) module, be sure to
deploy it before discarding it.
• When grease, cleaning agent, oil, water, etc., got on
the air bag (inflator) modules (driver and passenger),
wipe it off immediately with a dry cloth.
• If air bag (inflator) module was dropped from a height
of 90 cm (3 ft) or more, it should be replaced with a
new one as an assembly.

• Never attempt to disassemble the seat belt
pretensioners (retractor assembly).
• If any abnormality is found, be sure to replace it with
new one as an assembly.
• When an abnormality is noted as existing in the live
(inactivated) seat belt pretensioner, be sure to activate
it before discarding it.
• When grease, cleaning agent oil, water, etc., got on
the seat belt pretensioners (retractor assembly), wipe
it off immediately with a dry cloth.
• If seat belt pretensioner was dropped from a height of
30 cm (1 ft) or more, it should be replaced with a new
one as an assembly.
WARNING!
• For handling and storage of a live seat belt
pretensioner, select a place where the
ambient temperature below 65 °C (150 °F),
without high humidity and away from
electric noise.
• Never carry the seat belt pretensioner by
webbing.
• When placing a live seat belt pretensioner
on the workbench or other surface, be sure
not to lay it with its exhaust hole (1)
provided side facing down. It is also
prohibited to put something on its face
with an exhaust hole (1) or to put a seat
belt pretensioner on top of another.
Otherwise, personal injury may result.

Deployed Air Bag (Inflator) Module and Activated
Seat Belt Pretensioner
WARNING!
• The air bag (inflator) module and seat belt
pretensioner immediately after
deployment/activation is very hot. Wait for
at least 30 minutes to cool it off before
proceeding the work.
• Do not apply water, oil, etc. to deployed air
bag (inflator) module and to activate seat
belt pretensioner.
• After an air bag (inflator) module has been
deployed, the surface of the air bag may
contain a powdery residue. This powder
consists primarily of cornstarch (used to
lubricate the bag as it inflates) and by-
products of the chemical reaction. As with
many service procedures, gloves and
safety glasses should be worn.
• Wash your hands with mild soap and water
after completing the work.

Refer to the procedure described under “Deployed Air
Bag (Inflator) Module and Activated Seat Belt
Pretensioner Disposal” for disposal.
Air Bag Wire Harness and Connector
Air bag wire harness is included in main harness (1),
instrument panel harness (4), floor harness (3), seat
harness (5) and curtain air bag harness (6). Air bag wire
harness can be identified easily as the part of connector
side wire harness is covered with a yellow protection
tube. Be very careful when handling it.
• When an open in air bag wire harness, damaged wire
harness, connector or terminal is found, replace wire
harness, connectors and terminals as an assembly.
• When installing it, be careful so that the air bag wire
harness is not caught or does not interfere with other
parts.
• Make sure air bag system grounding point (2) is clean
and ground is securely fastened for optimum metal-to-
metal contact. Poor grounding can cause intermittent
problems that are difficult to diagnose.

Diagnostic Information and Procedures
Air Bag Diagnostic System CheckS6RW0D8204001
WARNING!
To avoid deployment when troubleshooting
the air bag system, do not use electrical test
equipment such as a battery powered or AC
powered voltmeter, ohmmeter, etc., or any
type of electrical equipment other than that
specified in this manual. Do not use a non-
powered probe type tester.
Instructions in this manual must be followed
carefully, otherwise personal injury may
result.

CAUTION!
• The order in which DTCs are diagnosed is
very important. Failure to diagnose the
DTCs in the order specified may result in
extended diagnostic time, incorrect
diagnosis and incorrect parts replacement.
• When measurement of resistance or
voltage is required in the flow, use a tester
along with a correct terminal adapter from
special tool (Connector test adapter kit).
• When a check for proper connection is
required, refer to “Inspection of
Intermittent and Poor Connections”.
• If an open circuit in the air bag wire
harness damaged, connector or terminal is
found, replace the wire harness,
connectors and terminals as an assembly.

The diagnostic procedures used are designed to find
and repair air bag system malfunctions.
To get the best results, it is important to use the
diagnostic flow and follow the sequence in the following.
1) Perform the “Air Bag Diagnostic System Check
Flow”.
(The “Air Bag Diagnostic System Check Flow” must
be the starting point of any air bag system diagnosis.
The “Air Bag Diagnostic System Check Flow” checks
for proper “AIR BAG” warning light operation through
“AIR BAG” warning light and whether air bag DTCs
exist.)
2) Refer to the proper diagnostic flow as directed by the
“Air Bag Diagnostic System Check Flow”.
(The “Air Bag Diagnostic System Check Flow” will
lead you to the correct flow to diagnose any air bag
system malfunctions. Bypassing these procedures
may result in extended diagnostic time, incorrect
diagnosis and incorrect parts replacement.)
3) Repeat the “Air Bag Diagnostic System Check Flow”
after any repair or diagnostic procedures have been
performed.
(Performing the “Air Bag Diagnostic System Check
Flow” after all repair or diagnostic procedures will
ensure that the repair has been made correctly and
that no other malfunctions exist.)
