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, if available.
2) Clear DTC.
3) Start engine, warm it up to normal operating temperature and shift transfer lever to ª2Hº or ª4Hº range.
4) Shift selector lever in D range and keep it there for 10 seconds.
5) Increase vehicle speed to about 80 km / h (50 mph) in 4th gear and in D range.
6) Keep driving at above speed for 20 seconds.
7) Release accelerator pedal, decrease vehicle speed and stop vehicle.
8) Check DTC and / or pending DTC.

(A / T gear position is calculated based on engine
speed signal and vehicle speed sensor signal.)

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 DTC, pending DTC and freeze frame data in PCM memory by using scan tool and check fuel level meter
indication is 1 / 4 or more.
3) Start engine, warm it up to normal operating temperature and shift transfer lever to ª2Hº or ª4Hº range.
4) Increase vehicle speed with D range, and check that gear position changes from 1st to 2nd, 3rd and 4th in that
order as vehicle speed increases, referring to ªGear Shift Diagramº in this section.
5) Stop vehicle and check pending DTC and DTC by using scan tool.

ROAD TEST
This test is to check if upshift and downshift take place at specified
speed while actually driving vehicle on a level road.
WARNING:
Carry out test in very little traffic area to prevent an acci-
dent.
Test requires 2 persons, a driver and a tester.
1) Warm up engine.
2) With engine running at idle, shift select lever ªDº.
3) Accelerate vehicle speed by depressing accelerator pedal grad-
ually.
4) While driving in ªDº range, check if gear shift occurs properly as
shown in Gear Shift Diagram in this section.

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 ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº 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 ªService Precau-
tionsº under ªOn-vehicle Serviceº 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
