DTC CheckS6RW0D8204004
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.
If connector and circuit are OK, check that DLC
circuit and power supply and ground circuits of SDM
are in good condition referring to “SDM Power
Supply and Ground Circuit Check” and “Serial Data
Link Circuit Check”.
5) After completing the check, turn ignition switch to
OFF position and disconnect SUZUKI scan tool from
data link connector (DLC) (1).
DTC ClearanceS6RW0D8204005
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 B1021 or DTC B1027 is
stored in SDM, it is not possible to clear DTC.

Removal
1) Disable air bag system. Refer to “Disabling Air Bag
System”.
2) Loosen seat back surface fastener (1) and roll up
backside of seat back surface.
3) Remove sleeve lock nut (1) from side-air bag
(inflator) module (2).
4) Remove side-air bag (inflator) module from seat
back.
5) Disconnect side-air bag (inflator) module connector
(1) as shown in the figure.
a) Unlock lock button (2).
b) With lock button unlocked, disconnect connector.WARNING!
• When carrying a live air bag (inflator)
module, make sure the bag opening is
pointed away from you.
Never carry air bag (inflator) module by
wires or connector on the side of the
module. In case of an accidental
deployment, the bag will then deploy with
minimal chance of injury.
• As the live side-air bag (inflator) module
must be kept with its bag (trim cover)
facing up while being stored or left
standing. This is necessary so that a free
space is provided to allow the air bag to
expand in the unlikely event of accidental
deployment.
• Observe “Precautions on Handling and
Storage of Air Bag System Components”
for handling and storing it.
Otherwise, personal injury may result.

6) Remove fastener (1) with sleeve (2) from seat back.
