On-Board Diagnostic System DescriptionS6RW0D5101005
NOTE
There are two types of OBD system
depending on the vehicle specification.For
identification, refer to “Precaution on On-
Board Diagnostic (OBD) System in Section
1A”.

For automatic transaxle control system, TCM has the
following functions.
• For Euro OBD model, when the ignition switch is
turned ON with the engine at a stop, MIL (1) turns ON
to check the bulb of the MIL.
• For Euro OBD model, when TCM detects a
malfunction in A/T control system TCM desires turning
on MIL and stores malfunction DTC in TCM memory.
(If it detects that continuously 3 driving cycles are
normal after detecting a malfunction, however, it
makes MIL turn OFF although DTC stored in its
memory will remain.)
• For Euro OBD model, it is possible to communicate
with TCM through data link connector (DLC) (2) by
using not only SUZUKI scan tool (3) but also CAN
communication OBD generic scan tool. (Diagnostic
information can be checked and erased by using scan
tool.)
• For non-Euro-OBD model, when ignition switch is
turned ON and no malfunction in A/T control system is
detected, transmission warning light (4) lights for
about 2 seconds after ignition switch is turned ON and
then goes OFF for bulb check.• For non-Euro-OBD model, when TCM detects a
malfunction in A/T control system, it indicates
transmission warning light (4) and stores malfunction
DTC in its memory.
• For information about the following items, refer to “On-
Board Diagnostic System Description in Section 1A”.

DTC CheckS6RW0D5104005
NOTE
• There are two types of OBD system
depending on the vehicle specification.For
identification, refer to “Precaution on On-
Board Diagnostic (OBD) System in Section
1A”.
• For Euro-OBD model, the MIL is turned on
when the ECM and/or TCM detect
malfunction(s). Each control module
stores diagnostic information as the
diagnostic trouble code (DTC) in its
memory and outputs the DTC to the scan
tool. Therefore, check both of the control
modules for any DTC with the SUZUKI
scan tool because the DTC stored in ECM
and TCM is not read and displayed at a
time. However, each of the control
modules needs not to be checked with the
CAN communication OBD generic scan
tool because the DTC stored in ECM and
TCM is read and displayed at a time. In
case using CAN communication OBD
generic scan tool, refer to “DTC Table in
Section 1A”.

1) Turn ignition switch to OFF position.
2) Connect scan tool to data link connector (DLC) (1).
Special tool
(A): SUZUKI scan tool (SUZUKI-SDT)
3) Turn ignition switch ON.
4) Read DTC, pending DTC and freeze frame data
according to instructions displayed on scan tool and
print it down. Refer to scan tool operator’s manual
for further details.
If communication between scan tool and TCM is not
possible, check if scan tool is communicable by
connecting it to TCM 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 off
and disconnect scan tool from data link connector. ) UP1723 Range select switch malfunction“3” position switch ON signal is inputted

General Description
Manual Transaxle ConstructionS6RW0D5201001
The transaxle provides five forward speeds and one reverse speed by means of three synchromesh devices and three
shafts-input shaft, countershaft and reverse gear shaft. All forward gears are in constant mesh, and reverse uses a
sliding idler gear arrangement.
The low speed sleeve & hub is mounted on countershaft and engaged with countershaft 1st gear or 2nd gear, while
the high speed sleeve & hub is done on input shaft and engaged with input shaft 3rd gear or 4th gear. The 5th speed
sleeve & hub on input shaft is engaged with input shaft 5th gear mounted on the input shaft.
To prevent the cracking noise from the reverse gear when shifting transaxle gear into the reverse gear, the reverse
shift braking device is used.
The device utilizes the 5th synchromesh, which is the lever synchro type, to apply the brake on the input shaft rotation.
The double cone synchronizing mechanism is provided to 2nd gear synchromesh device for high performance of
shifting to 2nd gear.
For servicing, it is necessary to use genuine sealant or its equivalent on mating surfaces of transaxle case which is
made of aluminum. The case fastening bolts must be tightened to specified torque by means of torque wrench. It is
also important that all parts are thoroughly cleaned with cleaning fluid and air dried before reassembling.
Further, care must be taken to adjust preload of countershaft taper roller bearings. New synchronizer rings are
prohibited from being lapped with respective gear cones by using lapping compound before they are assembled.

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.

General Description
Steering Wheel and Column ConstructionS6RW0D6201001
This double tube type steering column has the following three important features in addition to the steering function:
• The column is energy absorbing, designed to compress in a front-end collision.
• The ignition switch and lock are mounted conveniently on this column.
• With the column mounted lock, the ignition and steering operations can be locked to inhibit theft of the vehicle.
To insure the energy absorbing action, it is important that only the specified screws, bolts and nuts be used as
designated, and that they are tightened to the specified torque. When the column assembly is removed from the
vehicle, special care must be taken in handling it. Use of a steering wheel puller other than the recommended puller in
this manual or a sharp blow on the end of the steering shaft, leaning on the assembly, or dropping the assembly could
shear the plastic shear pins which maintain column length and position.
The driver air bag (inflator) module is one of the supplemental restraint (air bag) system components and is mounted
to the center of the steering wheel. During certain frontal crashes, the air bag system supplements the restraint of the
driver’s and passenger’s seat belts by deploying the air bags. The air bag (inflator) module should be handled with
care to prevent accidental deployment. When servicing, be sure to observe “Precautions on Service and Diagnosis of
Air Bag System in Section 8B”.
