Diagnostic Information and Procedures

Air Bag Diagnostic System Check

S6JB0B8204001

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 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.)

Air Bag Diagnostic System Check Flow

S6JB0B8204002

CAUTION

• Be sure to perform “Air Bag Diagnostic System Check” before starting diagnosis according to each

flow.

• 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.

Flow test description
Step 1: Check “AIR BAG” warning light and circuits.
Step 2: Check that “AIR BAG” warning light lights.
Step 3: Check diagnosis switch circuit.
Step 4: Check that “AIR BAG” warning light flashes 6 times after ignition switch is turned ON.
Step 6: Check that history code(s) is in SDM memory. (using SUZUKI scan tool)
Step 7: Check that history code(s) is in SDM memory. (using monitor coupler)
Step 9: Check that current code is in SDM memory. (using SUZUKI scan tool)
Step 10: Check that current code is in SDM memory. (using monitor coupler)

Step

Action

Yes

1) Make sure that battery voltage is about 11 V or higher.
2) Note “AIR BAG” warning light as ignition switch is turned

ON.

Does “AIR BAG” warning light come ON when ignition
switch is turned ON?

Go to Step 2.

Proceed to ““AIR BAG”
Warning Light Does Not
Come ON”.

Does “AIR BAG” warning light come ON steady?

Proceed to ““AIR BAG”
Warning Light Comes
ON Steady”.

Go to Step 3.

Does “AIR BAG” warning light keep flashing (indicating
DTC) when ignition switch is ON?

Proceed to ““AIR BAG”
Warning Light Flashes”.

Go to Step 4.

Does “AIR BAG” warning light turn OFF, after flashing 6
times?

“AIR BAG” warning light
circuit is in good
condition. Go to Step 5.

“AIR BAG” warning light
circuit is in good
condition. Go to Step 8.

Do you have SUZUKI scan tool?

Go to step 6.

Go to step 7.

Check DTC referring to “DTC Check” using SUZUKI scan
tool.

Is “NO CODES” displayed on SUZUKI scan tool?

Air bag system is in
good condition.

An intermittent trouble
has occurred at some
place.
Check the connector
harness, etc. related to
the sensed DTC.
Refer to “Inspection of
Intermittent and Poor
Connections”.
Then clear DTC
(referring to “DTC
Clearance”.) and repeat
this flow.

1) Check DTC referring to “DTC Check” using monitor

connector (if equipped).

Is flashing pattern DTC No. 0000 indicated on “AIR BAG”
warning light?

Air bag system is in
good condition.

Do you have SUZUKI scan tool?

Go to step 9.

Go to step 10.

Check DTC referring to “DTC Check” using SUZUKI scan
tool.

Is “NO CODES” displayed on SUZUKI scan tool?

Substitute a known-
good SDM and recheck.

Check and repair
according to flow
corresponding to that
DTC.

10 Check DTC referring to “DTC Check” using monitor

connector (if equipped).

Is flashing pattern DTC No. 0000 indicated on “AIR BAG”
warning light?

Substitute a known-
good SDM and recheck.

Check and repair
according to flow
corresponding to that
DTC.
