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.
• When power to 4WD control module is cut
off (by disconnecting battery cable,

Transfer
General Description
Transfer DescriptionS6RW0D3301001
The transfer is mounted on transaxle case by fastening bolt with reduction drive gear in transfer and differential case in
transaxle coupled by involute spline. Driving force from transaxle is transmitted to propeller shaft through reduction
drive gear, reduction driven gear and bevel gear of transfer. As bevel gears, which change the direction of driving
torque axis to the direction of the angle with 90 degrees, hypoid gears are provided. Hypoid gears have an advantage
of preventing gear noise, at the same time, they require accurate adjustment of tooth contact and backlash.

d) Select a shim which is close to half thickness of
the calculated value (necessary shim thickness)
from among the available shims to install it
between bearing and case at each of right and
left sides.
For example:
Measure distance “a” is 110.75 mm (4.360 in.).
Measure depth “b” is 85.8 mm (3.378 in.).
Measure depth “c” is 26.55 mm (1.045 in.).
Necessary shim thickness = 85.8 mm (3.378 in.)
+ 26.55 mm (1.045 in.) – 110.75 mm (4.360 in.) +
0.1 mm (0.004 in.) = 1.7 mm (0.067 in.)
1.7 mm (0.067 in.) ÷ 2 = 0.85 mm (0.033 in.)
Calculated thickness of new shim = 0.85 mm

tightening retainer bolt (1) to specified torque.
Tightening torque
Transfer output retainer bolt (a): 55 N·m (5.5 kgf-
m, 40.0 lb-ft)
8) Install bolt to bolt hole of flange (2), set dial gauge
measuring tip at right angles to bolt (1) as shown in
figure. Holding reduction driven gear by hand, take
measurement backlash of pinion and bevel gear.
