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.)

NOTE
Upon completion of inspection and repair work, perform the following items.
• Reconnect all air bag system components and ensure all components are properly mounted.
• Repeat “Air Bag Diagnostic System Check” to confirm that the trouble has been corrected.
• Clear DTC B1157 (air bag deployed) of BCM referring to “DTC Clearance in Section 10B”, if any.
