DTC Confirmation Procedure
WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic
accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and a tester, on a level road.

1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTCs in TCM memory by using scan tool.
3) Start engine and shift select lever to “D” range.
4) Start vehicle and increase vehicle speed to 40 km/h (25 mile/h) or more for 1 minutes.
5) Stop vehicle and turn ignition switch OFF.
6) Repeat Step 3) to 4) one time.
7) Stop vehicle and check DTC.
DTC Troubleshooting
Step Action Yes No
1Was “A/T System Check” performed?Go to Step 2. Go to “A/T System
Check”.
2Do you have SUZUKI scan tool?Go to Step 3. Go to Step 4.
3Check transmission range sensor circuit for operation
Check by using SUZUKI scan tool:
1) Connect SUZUKI scan tool to DLC with ignition switch

2) Turn ignition switch ON and check transmission range
signal (P, R, N, D, 2 or L) on display when shifting select
lever to each range.
Is applicable range indicated?Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.Go to Step 5.
4Check transmission range sensor circuit for operation
Check by not using SUZUKI scan tool:
1) Turn ignition switch ON.
2) Check voltage at terminals “C07-1”, “C07-7”, “C07-8”,
“C07-18”, “C07-19” and “C07-20” respectively with
select lever shifted to each range.
Taking terminal “C07-19” as an example, is battery
voltage indicated only when select lever is shifted to “2”
range and 0 V for other ranges as shown in the following
table.
Check voltage at other terminals likewise, referring to the
following table.
Are check results satisfactory?Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section

shift shaft (2) and high speed gear shift shaft (3)
assemblies all together, then install them into right
case (1) so as not to damage oil seal by input shaft
spline.
NOTE
• Input shaft right bearing on shaft can be
installed into right case (1) by tapping shaft
with plastic hammer.
• Make sure that countershaft is engaged
with final gear while installing.

3) Install 5th & reverse gear shift shaft (1) with 5th &
reverse gear shift guide shaft (2) into right case (5).
Reverse gear shift arm (4) has to be joined with
reverse gear shift lever (3) at the same time.4) Make reverse idler gear (1) with reverse gear shift
lever (2), insert reverse gear shaft (3) and washer (6)
into case (4) through idler gear and then align bolt
hole “a” in shaft with notch “b” in case.
5) Fasten reverse gear shift lever bolts (5) after
applying thread lock cement.
“A”: Thread lock cement 99000–32110 (Thread
Lock Cement Super 1322)
Tightening torque
Reverse gear shift lever bolt (a): 23 N·m (2.3 kgf-
m, 17.0 lb-ft)
NOTE
Check to confirm that reverse gear shift lever
end has clearance “c” to idler gear groove.

Distance between lever end and idler gear shaft
“c”: 0.5 – 1.0 mm (0.02 – 0.04 in.)

Transmission / Transaxle
Clutch
General Description
Clutch (Hydraulic Type) ConstructionS6RW0D5301001
The clutch is a diaphragm spring clutch of a dry single disc type. The diaphragm spring is of a tapering-finger type,
which is a solid ring in the outer diameter part, with a series of tapered fingers pointing inward.
The disc, carrying four torsional coil springs, is positioned on the transaxle input shaft with an involute spline fit.
The clutch cover is secured to the flywheel, and carries the diaphragm spring in such a way that the peripheral edge
part of the spring pushes on the pressure plate against the flywheel (with the disc in between), when the clutch release
bearing (incorporated in clutch operating cylinder) is held back. This is the engaged condition of the clutch.
Depressing the clutch pedal causes the release bearing (incorporated in clutch operating cylinder) to advance and
pushes on the tips of the tapered fingers of the diaphragm spring. When this happens, the diaphragm spring pulls the
pressure plate away from the flywheel, thereby interrupting the flow of drive from flywheel through clutch disc to
transaxle input shaft. Clutch fluid is supplied from brake fluid reservoir. Clutch fluid level can be checked by brake fluid
level of brake fluid reservoir.
