Diagnostic Information and Procedures
Air Bag Diagnostic System CheckS7RS0B8204001
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.

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 right operation
through “AIR BAG” warning right and whether air
bag DTCs exist.)
2) Refer to the proper diagnost ic 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.)

SDM InspectionS7RS0B8206004
WARNING!
During service procedures, be very careful
when handling a Sensing and Diagnostic
Module (SDM).
Be sure to read “Precautions on Service and
Diagnosis of Air Bag System” before starting
to work and observe every precaution during
work. Neglecting them ma y result in personal
injury or inactivation of the air bag system
when necessary.

CAUTION!

5) Remove passenger air bag (inflator) module (1) from air bag hole cover (2).
WARNING!
• When carrying a live air bag (inflator) module, make sure the bag opening is
pointed away from you.
Never carry air bag (inflator) module by
wires or connector on the side of the
module. In case of an accidental
deployment, the bag will then deploy with
minimal chance of injury.
• As the live passenger air bag (inflator) module must be kept with its bag (trim
cover) facing up while being stored or left
standing, place it on the workbench with a
slit facing down or use the workbench vise
to hold it securely at its lower mounting
bracket. This is necessary so that a free
space is provided to allow the air bag to
expand in the unlikely event of accidental
deployment.
• Observe “Precautions on Handling and Storage of Air Bag System Components”
for handling and storing it.
Otherwise, personal injury may result.

Installation
1) Install passenger air bag (inflator) module to air bag hole cover (2).
CAUTION!
Confirm claw (1) of passenger air bag
