WARNING:
For vehicles equipped with Supplement 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 or 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).

ENGINE VACUUM CHECK
The engine vacuum that develops in the intake line is a good indica-
tor of the condition of the engine. The vacuum checking procedure
is as follows:
1) Warm up engine to normal operating temperature.
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.
2) With engine stopped, disconnect EVAP canister purge valve
hose from intake manifold and connect 3-way joint, hoses and
special tools (vacuum gauge and joint) between intake manifold
and vacuum hose disconnected.

DISASSEMBLY
NOTE:

Be sure not to remove either fuel pressure regulator or idle
speed control actuator from throttle body. They are factory
adjusted precisely.

Be sure to replace gaskets and O-rings as well as worn or
damaged parts.

While disassembling and assembling throttle body, use spe-
cial care not to deform levers on throttle valve shaft or cause
damage to any other parts.
1) Remove fuel injector from throttle body according to procedure
described in FUEL INJECTOR REMOVAL.
2) Remove TP sensor.
3) After removing screws, separate upper and lower bodies.
CLEANING
Clean passages and fuel injector chamber by blowing compressed
air.
NOTE:

TP sensor, fuel pressure regulator, fuel injector, ISC actua-
tor, other components containing rubber (resin) or throttle
valve shaft seal must not be placed in a solvent or cleaner
bath. Chemical reaction will cause these parts to swell, hard-
en or get distorted.

Don’t put drills or wires into passages for cleaning. It causes
damage in passages.

3) Install accelerator cable to throttle valve lever and cable brack-
et.
4) Connect fuel, cooling water and vacuum hoses to throttle body,
and clamp securely.
5) Connect TP sensor and injector couplers securely.
6) Refill cooling system referring to Section 6B.
7) Connect negative cable at battery.
8) With engine “OFF” and ignition switch “ON”, check for fuel
leaks around fuel line connection.
9) Install air cleaner assembly referring to Section 6A.
10) Upon completion of installation, start engine and check for fuel
leaks and engine coolant leaks.
Adjust cable play to specification according to procedure de-
scribed in ACCELERATOR CABLE ADJUSTMENT.
FUEL INJECTOR
ON-VEHICLE INSPECTION
1) With battery negative cable disconnected, disconnect injector
coupler.
2) Connect ohmmeter to each injector terminal and measure resis-
tance.
Resistance of injector: 0.5 – 1.5 Ω at 20C (68F)
If resistance is out of specification, replace fuel injector.
3) Connect injector coupler.
4) Remove air cleaner assembly without disconnecting IAT sensor
coupler.
5) Check that fuel is injected out in conical shape from fuel injector
when cranking or running engine.
If no fuel is injected, check wiring harness for continuity and cou-
plers for proper connection referring to “DIAGNOSTIC FLOW
TABLE B-1”.
If fuel is not injected out in conical shape, replace injector.
6) Check injector for fuel leakage after injection is stopped (i.e., af-
ter cranking or engine stop).
Replace if leakage exists.
Fuel leakage: Less than 1 drop/min.
7) Install air cleaner assembly.

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.
