ROAD TEST
This test is to check if upshift and downshift take place at specified
speeds while actually driving vehicle on a level road.
WARNING:

Carry out the test in very little traffic area to prevent an ac-
cident.

The test requires 2 persons, a driver and a tester.
1) Warm up engine.
2) With engine running at idle, shift selector lever to D range.
3) i) Accelerate vehicle speed by depressing accelerator pedal
very little (within 4 deg. of throttle valve opening).
ii) Check if upshift takes place from 1st to 2nd at about 18 km / h
(11 mile / h) and from 2nd to 3rd at about 30 km / h (19 mile / h).
iii)
[For G10 Engine Model]
Stop vehicle once. Then start it again and while accelerating
by depressing accelerator pedal fully, check if upshift takes
place from 1st to 2nd at 52 km / h (33 mile / h) and from 2nd to
3rd at 97 km / h (61 mile / h).
[For G13 Engine Model]
Stop vehicle once. Then start it again and while accelerating
by depressing accelerator pedal fully, check if upshift takes
place from 1st to 2nd at 58 km / h (36 mile / h) and from 2nd to
3rd at 110 km / h (69 mile / h).
iv) Stop vehicle again.
v) Start vehicle and keep it running at 25 km / h (15 mile / h) and
then release accelerator pedal completely. 1 or 2 seconds lat-
er, depress accelerator pedal fully and check if downshift
from 2nd to 1st takes place.
vi) Keep vehicle running at 75 km / h (47 miles / h) and in the
same way as in step v), check if downshift from 3rd to 2nd
takes place.
vii) If upshift or downshift fails to take place at each specified
speed in the road test, possible causes for such failure are as
follows. Check each part which is suspected to be the cause.
Condition
Possible causes
No upshift from 1st
to 2nd
1 – 2 shift valve defective

3) Disconnect shift solenoid valve coupler from harness.
4) Apply 12 V to each terminal in solenoid valve coupler and check
to be sure that a click sound is heard from each of shift sole-
noid-A and -B.
If no click sound is heard, check lead wire and connections in oil
pan, and then replace applicable shift solenoid-A or B if wire and
connections are in good condition.
If click sound is heard from each of shift solenoids A and B, shift
solenoid electrical circuits are in good condition. Proceed to

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.

KEYLESS ENTRY SYSTEM (IF EQUIPPED)
The keyless entry system uses radio wave. When the button on the transmitter is pressed, a signal is transmitted
in the form of radio wave to the receiver. Then the signal causes the door lock controller to lock and unlock the door.
The door locks can not operated with the transmitter when either of the following conditions applies.

For 2 seconds after the ignition switch is turned from ON to OFF position.

The ignition switch is at ON or START position.

Any door is open.
