NOTE:
When 2 or more codes are indicated, the lowest numbered code will appear first.
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 or 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.
(Abnormality exists at present.)History DTC is set only.
(Faulty condition occurred once
in the past but normal condition
is restored at present.)

TABLE TEST DESCRIPTION
STEP 1 : This test rechecks “AIR BAG” warning lamp operation.
STEP 2 : This test rechecks whether an abnormality is in SDM.
DTC B1061 :
DTC B1071 – Internal SDM Fault
DTC WILL SET WHEN
An internal SDM fault is detected by SDM.
DTC B1013 – System Specifications Different from SDM Specifications
DTC WILL SET WHEN
Specifications of the air bag system differ from those of SDM.Step Action Yes No
1 1) This DTC is set when there is a trouble in
“AIR BAG” warning lamp circuit. Failure to
properly perform AIR BAG DIAGNOSTIC
SYSTEM CHECK may also result in mis-
diagnosis. Therefore, check “AIR BAG”
warning lamp circuit again according to
AIR BAG DIAGNOSTIC SYSTEM
CHECK.
Is “AIR BAG” warning lamp circuit in good
condition?Go to step 2. Repair “AIR BAG” warning
lamp circuit.
2 1) Clear DTC (Refer to DTC CLEARANCE).
2) Check DTC (Refer to DTC CHECK).
Is DTC B1061 set?Substitute a known-
good SDM and recheck.Recheck air bag system.
Refer to AIR BAG DIAG-
NOSTIC SYSTEM CHECK.
NOTE:
Upon completion of inspection and repair work, perform following items.
Reconnect all air bag system components, ensure all components are properly mounted.
Repeat AIR BAG DIAGNOSTIC SYSTEM CHECK to confirm that the trouble has been corrected.
NOTE:
DTC B1071 can never be cleared once it has been set.
1) Ignition switch OFF.
2) Replace SDM.
3) Repeat AIR BAG DIAGNOSTIC SYSTEM CHECK.
NOTE:
Before executing items below, be sure to perform AIR BAG DIAGNOSTIC SYSTEM CHECK.
1) Ignition switch OFF.
2) Replace SDM.
3) Repeat AIR BAG DIAGNOSTIC SYSTEM CHECK.

AIR BAG SYSTEM 10B-55
AIR BAG WIRE HARNESS AND CONNECTOR
Air bag wire harness (1) can be identified easily as it is covered
with a yellow protection tube. Be very careful when handling it.
•When an open in air bag wire harness (1), damaged wire
harness, connector or terminal is found, replace wire har-
ness, connectors and terminals as an assembly.
•When installing it, be careful so that the air bag wire harness
(1) is not caught or does not interfere with other parts.
•Make sure all air bag system grounding points (2) are clean
and grounds are securely fastened for optimum metal-to-
metal contact. Poor grounding can cause intermittent prob-
lems that are difficult to diagnose.
DISPOSAL
Do not dispose of the live (undeployed) air bag (inflator) modules
and the live (inactivated) seat belt pretensioners. When disposal
is necessary, be sure to deploy/activate the air bag and seat belt
pretensioner according to deployment/activation procedure
described in “AIR BAG (INFLATOR) MODULE AND SEAT BELT
PRETENSIONER DISPOSAL”.

WARNING:
Failure to follow proper air bag (inflator) module and seat
belt pretensioner disposal procedures can result in air
bag deployment and pretensioner activation which could
cause personal injury. Undeployed air bag (inflator) mod-
ule and inactivated seat belt pretensioner must not be
disposed of through normal refuse channels.
The undeployed air bag (inflator) module and inactivated
seat belt pretensioner contain substances that can cause
severe illness or personal injury if the sealed container is
damaged during disposal.
