EVAP CANISTER PURGE INSPECTION
NOTE:
Before inspection, check to make sure that gear shift lever is
in neutral position (with A / T model, selector lever in “P” range)
and that parking brake lever is pulled all the way up.
1) Disconnect purge hose from EVAP canister.
2) Place finger against the end of disconnected hose and check
that vacuum is not felt there when engine is cool and running at
idle speed.
3) Connect purge hose to EVAP canister and warm up engine to
normal operating temperature.
4) Disconnect purge hose from EVAP canister.
5) Also check that vacuum is felt when engine is running at idle
speed.
NOTE:
The EVAP canister purge system does not perform purging
(vacuum is not detected at the purge hose) unless the en-
gine is sufficiently warmed up and the heated oxygen sen-
sor is activated fully. Also, when the purge hose is discon-
nected in Step 4), the air is drawn into the purge line. As a
result, ECM detects a change in the purge gas concentra-
tion and sometimes stops purging but this indicates noth-
ing abnormal.
If check result is not satisfactory, check vacuum passage, hoses,
EVAP canister purge valve, wire harness and ECM.
VACUUM PASSAGE INSPECTION
Start engine end run it at idle speed. Disconnect vacuum hose from
EVAP canister purge valve. With finger placed against hose discon-
nected, check that vacuum is applied.
If it is not applied, clean vacuum passage by blowing compressed
air.
VACUUM HOSE INSPECTION
Check hoses for connection, leakage, clog and deterioration. Re-
place as necessary.

1) Disconnect purge hose (1) from EVAP canister.
2) Place finger against the end of disconnected hose and check
that vacuum is not felt there when engine is cool and running at
idle speed.
3) Connect purge hose to EVAP canister and warm up engine to
normal operating temperature.
4) Disconnect purge hose from EVAP canister.
5) Also check that vacuum is felt when engine is running at idle
speed.
NOTE:
The EVAP canister purge system does not perform purging
(vacuum is not detected at the purge hose) unless the en-
gine is sufficiently warmed up and the heated oxygen sen-
sor is activated fully. Also, when the purge hose is discon-
nected in Step 4), the air is drawn into the purge line. As a
result, ECM (PCM) detects a change in the purge gas con-
centration and sometimes stops purging but this indicates
nothing abnormal.
If check result is not satisfactory, check vacuum passage, hoses,
EVAP canister purge valve, wire harness and ECM (PCM).
Vacuum Passage Inspection
Start engine and run it at idle speed. Disconnect vacuum hose (1)
from EVAP canister purge valve (2). With finger placed against
hose disconnected, check that vacuum is applied.
If it is not applied, clean vacuum passage by blowing compressed
air.
Vacuum Hose Inspection
Check hoses for connection, leakage, clog and deterioration. Re-
place as necessary.
EVAP Canister Purge Valve Inspection
Check EVAP canister purge valve referring to step 1 of DTC P0443
Flow Table.
If found malfunction, replace.

AUTOMATIC TRANSMISSION (3 A/T)
(VEHICLE WITH WU-TWC)
WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under “Gener-
al Description” in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and “Service Precau-
tions” under “On-Vehicle Service” in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
For the descriptions (items) not found in this section, refer to the same section of the Service Manual men-
tioned in the FOREWORD of this manual.

AUTOMATIC TRANSMISSION (3 A / T) (VEHICLE WITH WU-TWC) 7B-3
GENERAL DESCRIPTION
The automatic transmission consists of the hydraulic torque converter, electronically controlled 3-speed automatic
transmission, countershaft and differential.
The transmission consists of 2 planetary gears, 2 disk clutches, 1 band brake, 1 disk brake and 1 one-way clutch.
Its operation is controlled by selecting a position from 6 positions (P, R, N, D, 2 and L ranges) manually by means
of the selector lever installed on the compartment floor.
In the D or 2 range, the gear ratio is changed for the 1st, 2nd or 3rd speed (D range only) automatically by engine
control module (electronic control).
For the automatic transmission fluid, DEXRON
-

E, DEXRON-


or its equivalent must be used. Lubrication
in the automatic transmission is provided by the oil pump which is operated by the engine revolution. Therefore,
the engine should not be stopped even during coasting to obtain proper lubrication.
When it becomes necessary to be towed, front wheels must be raised so as not to roll them.

7B-8 AUTOMATIC TRANSMISSION (3 A / T) (VEHICLE WITH WU-TWC)
TRANSMISSION RANGE SENSOR (SHIFT SWITCH)
Being linked with the selector lever, this sensor changes selector
lever positions into electric signals and send them to the engine
control module. The contact points of this sensor for P and N ranges
are also connected with the starting motor circuit.
So when the selector lever is shifted to the P or N range position,
the contact points for P or N range are connected and cause the
starting motor to operate by turning the starter switch ON.
When the selector lever is in any other position than P and N
ranges, the sensor remains OFF and therefore the starting motor
cannot be operated, that is, the engine cannot be started.
Also, as its contact point for R range is connected with the backup
lamp circuit, only when the selector lever is shifted to R range, the
contact point contacts to light the backup lamp.
DIRECT CLUTCH AND 2ND BRAKE SOLENOID
VALVES
These solenoid valves are mounted on the valve body. They are
turned ON and OFF by the signals from the engine control module
and actuate each shift valve (1 – 2 and 2 – 3 valves) so as to control
transmission gear shift.
Shift solenoid-B (2nd brake solenoid valve) operates 1 – 2 shift
valve, and shift solenoid-A (direct clutch solenoid valve) does 2 –
3 shift valve.
