Visual InspectionS6RW0D3204004
Check the following parts and systems visually.
DTC CheckS6RW0D3204005
1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector
(DLC) (1) located on underside of instrument panel.
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 SUZUKI scan tool and
4WD control module is not possible, check if
SUZUKI scan tool is communicable by connecting it
to 4WD control module in another vehicle. If
communication is possible in this case, SUZUKI
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 OFF
and disconnect SUZUKI scan tool from data link
connector (DLC).
DTC ClearanceS6RW0D3204006
1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector
(DLC) (1) located on underside of instrument panel.
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 clearance, turn ignition switch OFF
and disconnect SUZUKI scan tool from data link
connector (DLC).
6) Perform “DTC Check” and confirm that NO CODES
is displayed.
NOTE
DTC stored in 4WD control module memory
are also cleared in the following cases. Be
careful not to clear them before keeping their
record.

off (by disconnecting battery cable,
removing fuse or disconnecting 4WD
control module connectors).
• When the same malfunction (DTC) is not
detected again during 40 engine warm-up
cycles.
