DTC CheckS7RS0B8204004
1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector (DLC) located on underside of instrument panel at
driver’s seat side.
Special tool
(A): SUZUKI scan tool
3) Turn ignition switch to ON position.
4) Read DTC according to instructions displayed on SUZUKI scan tool and print it or write it down. Refer
to SUZUKI scan tool operator’s manual for further
details.
If communication between scan tool and SDM is not
possible, check if scan tool is communicable by
connecting it to SDM in another vehicle. If
communication is possible in this case, scan tool is
in good condition. Then check data link connector
and serial data line (circuit) in the vehicle with which
communication was not possible. 5) After completing the check,
turn ignition switch to
OFF position and disconnect SUZUKI scan tool from
data link connector (DLC) (1).
DTC ClearanceS7RS0B8204005
1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector (DLC) (1) in the same manner as when making this
connection for DTC check.
Special tool
(A): SUZUKI scan tool
3) Turn ignition switch to ON position.
4) Erase DTC according to instructions displayed on
SUZUKI scan tool. Refer to SUZUKI scan tool
operator’s manual for further details.
5) After completing the clearance, perform “DTC Check” and confirm that normal DTC (NO CODES)
is displayed and not malfunction DTC.
6) Turn ignition switch to OFF position and disconnect SUZUKI scan tool from DLC.
NOTE
If DTC B1013, DTC B1 021 or DTC B1027 is
stored in SDM, it is not possible to clear DTC.

DTC Will Set when
The combined resistance of the driver air bag (inflator) module, contact coil assembly, harness wiring and connector
terminal contact is above a spec ified value for specified time.
Flow Test Description
Step 1: Check whether malfunction is in contact coil and driver air bag (inflator) module or the others.
Step 2: Check driver air bag (inflator) module initiator circuit. (in instrument panel and floor harness)
Step 3: Check driver air bag (inflator) module initiator circuit. (in floor harness)
Step 4: Check whether malfunction is in contact coil or driver air bag (inflator) module.
DTC Troubleshooting
Step Action Yes No 1 1) With ignition switch OFF, disconnect contact coil connector located under of the steering column.
2) Check proper connection to contact coil at terminal in “G26” connector.
3) If OK, then connect special tools (B) and (C) to “G26” connector disconnected in Step 1).
Special tool
(B): 09932-75010
(C): 09932–78340
4) Check SDM DTC.
With ignition switch ON , is DTC B1031 indicated? Go to Step 2. Go to Step 4.

DTC B1032: Driver Air Bag Initiator Circuit Resistance LowS7RS0B8204019
Wiring Diagram
CAUTION!
• Be sure to perform “Air Bag Diagnostic System Check” before starting diagnosis according to flow.
• When measurement of resistance or voltage is required in this 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 there is open circuit in the air bag wire harnes s, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.
DTC Will Set when
The combined resistance of the driver air bag (inflator) module, contact coil assembly, harness wiring and connector
terminal contact is below a spec ified value for specified time.
