(65 – 75 km / h)
28 – 34 mph
(45 – 55 km / h)
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 tester, on a level road.
1) Turn ignition switch OFF.
Clear DTC with ignition switch ON, check vehicle and environmental condition for:
–Altitude (barometric pressure): 2400 m, 8000 ft or less (560 mmHg, 75 kPa or more)
–Intake air temp.: between –10C and 80C (14F and 158F)
–Engine coolant temp.: 70C, 230F or higher
2) Start engine and drive vehicle at 41 – 46 mph, 65 – 75 km / h for 8 min. or longer.
While this driving, if “Catalyst Monitoring TEST COMPLETED” is displayed in “READINESS TESTS” mode and
DTC is not displayed in “DTC” mode, confirmation test is completed.
If “TEST NOT COMPLTD” is still being displayed, continue test driving.
3) Decrease vehicle speed at 28 – 34 mph, 45 – 55 km / h, and hold throttle valve at that opening position for 2 min.
and confirm that short term fuel trim vary within –20% –+20% range.
4) Stop vehicle (do not turn ignition switch OFF) and confirm test results according to following “Test Result Con-
firmation Flow Table”.
Test Result Confirmation Flow Table
STEPACTIONYESNO
1Check DTC in “DTC” mode and pending DTC in
“ON BOARD TEST” or “PENDING DTC” mode.
Is DTC or pending DTC displayed?Proceed to applicable
DTC Diag. Flow Table.Go to Step 2.
2Set scan tool to “READINESS TESTS” mode and
check if testing has been completed.
Is test completed?No DTC is detected
(confirmation test is
completed).Repeat DTC

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 Service Manual men-
tioned in FOREWORD of this manual.

COMPRESSION CHECK
Check compression pressure on all four cylinders as follows:
1) Warm up engine.
2) Stop engine after warming up.
NOTE:
After warming up engine, place transmission gear shift le-
ver in “Neutral” (shift selector lever to “P” range for A / T
model), and set parking brake and block drive wheels.
3) Remove ignition coil assemblies (1) and all spark plugs (2) refer-
ring to Section 6F.
WARNING:
Failure in disconnecting couplers from ignition coil as-
semblies can cause spark to occur in engine room possi-
bly resulting in a dangerous explosion.
4) Disconnect fuel injector wire harness at couplers (2).
5) Install special tools (Compression gauge) into spark plug hole.

(B): 09915-64510-002
(C): 09915-64530
(D): 09915-67010
6) Disengage clutch (to lighten starting load on engine) for M / T
model, and depress accelerator pedal all the way to make
throttle valve full-open.
7) Crank engine with fully charged battery, and read the highest
pressure on compression gauge.

8) Carry out steps 5) through 7) on each cylinder to obtain four
readings.
9) After checking, connect couplers to fuel injectors securely and
install spark plugs and ignition coil assemblies.
