10B-8 AIR BAG SYSTEM
INTERMITTENTS AND POOR CONNECTIONS
Most intermittents are caused by faulty electrical connections or
wiring. When a check for proper connection is requested in a
diagnostic flow table, perform careful check of suspect circuits for:
Poor mating of connector halves, or terminals not fully
seated in the connector body (backed out).
Dirt or corrosion on the terminals. The terminals must be
clean and free of any foreign material which could impede
proper terminal contact.
However, cleaning the terminal with a sand paper or the like
is prohibited.
Damaged connector body, exposing the terminals to mois-
ture and dirt, as well as not maintaining proper terminal ori-
entation with the component or mating connector.
Improperly formed or damaged terminals.
Check each connector terminal in problem circuits carefully
to ensure good contact tension by using the corresponding
mating terminal included in the connector test adapter kit
(special tool).
If contact tension is not enough, reform it to increase contact
tension or replace.
Special tool
(A) : 09932-76010 (Connector Test Adapter Kit)
Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor con-
nection by shaking it by hand lightly. If any abnormal condi-
tion is found, change the wire harness assembly or
component parts with new ones.
Wire insulation which is rubbed through, causing an intermit-
tent short as the bare area touches other wiring or parts of
the vehicle.
Wire broken inside the insulation. This condition could cause
a continuity check to show a good circuit, but if only 1 or 2
strands of a multi-strand-type wire are intact, resistance
could be far too high.
If any abnormality is found, repair or replace as a wire harness
assembly.

AIR BAG SYSTEM 10B-9
AIR BAG DIAGNOSTIC SYSTEM CHECK
The diagnostic procedures used in this section are designed to find and repair air bag system malfunctions.
To get the best results, it is important to use the diagnostic flow tables and follow the sequence listed below.
1) Perform the AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE.
(The AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE must be the starting point of any air bag sys-
tem diagnosis.
The AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE checks for proper “AIR BAG” warning lamp
operation through “AIR BAG” warning lamp and whether air bag diagnostic trouble codes exist.)
2) Refer to the proper diagnostic table as directed by the AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW
TABLE.
(The AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE will lead you to the correct table to diagnose
any air bag system malfunctions. Bypassing these procedures may result in extended diagnostic time, incor-
rect diagnosis and incorrect parts replacement.)
3) Repeat the AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE after any repair or diagnostic proce-
dures have been performed.
(Performing the AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE after all repair or diagnostic pro-
cedures will ensure that the repair has been made correctly and that no other malfunctions exist.)
FLOW TABLE TEST DESCRIPTION
STEP 1 : Check that “AIR BAG” warning lamp lights.
STEP 2 : Check that “AIR BAG” warning lamp lights.
STEP 3 : Check diagnosis switch circuit.
STEP 4 : Check that “AIR BAG” warning lamp flashes 6 times after ignition switch is turned ON.
STEP 6 : Check that history codes are in SDM memory. (using SUZUKI scan tool)
STEP 7 : Check that history codes are 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)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 equip-
ment 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 diagnostic trouble codes are diagnosed is very important. Failure to diagnose the
diagnostic trouble codes in the order specified may result in extended diagnostic time, incorrect diag-
nosis and incorrect parts replacement.

Current DTC and history DTC can be identified by lighting and flashing of “AIR BAG” warning lamp
as follows. However, if a multiple number of DTC’s are set an even one of them is a current DTC,
“AIR BAG” warning lamp remains on after ignition switch is turned ON. Therefore, it is not possible
to identify any of them as to whether it is a current one or a history one. (But use of SUZUKI scan
tool will make identification possible.)
Current DTC is set.
