REMOVAL
NOTE:
Use care when handling fuel injector especially not to damage
filter and its needle.
Also, because injector is an electrical component, it should
not be immersed in any type of liquid solvent or cleaner, or it
may get damaged.
1) Relieve fuel pressure, referring to Section 6.
2) Disconnect battery negative cable at battery.
3) Remove air cleaner assembly referring to Section 6A.
4) Remove air cleaner mounting stay from throttle body.
5) Remove injector wire and then remove fuel injector from throttle
body.
INSPECTION
Check fuel injector filter for evidence of dirt and contamination. If
present, clean and check for presence of dirt in fuel lines and fuel
tank.
INSTALLATION
1) Apply thin coat of spindle oil or gasoline to new upper and lower
O-rings, install lower O-ring and upper O-ring to injector.
2) Install injector by pushing it straight into fuel injector cavity.
Never turn injector while pushing it.

ENGINE AND EMISSION CONTROL SYSTEM (TBI FOR G10) 6E1-27
1) Connect scan tool to DLC with ignition switch OFF, if it is avail-
able.
2) Warm up engine to normal operating temperature.
3) Select “Data List” mode on scan tool to check “IAC duty”.
4) Apply load to engine as described below and check that idle
speed is kept at specified level and “IAC duty” increases as spe-
cified below. At the same time, check that plunger of ISC actua-
tor moves.
Increase of ISC duty
when headlight turns ON : About 3.5%
when A / C is operating : About 10%
5) Stop engine and leave it as it is till it cools off. Then check that
plunger of ISC actuator moves when ignition switch is turned
from OFF to ON once.
If abnormality is found in Steps 4) and 5), check ISC relay, ISC
actuator, ISC electric circuit and closed throttle position switch
signal.
If abnormality is found in Step 4) only, check A/C signal circuit
or power steering pressure switch signal circuit first.
ISC ACTUATOR
NOTE:
As ISC actuator has been preadjusted precisely at factory, it must
not be taken out of throttle body or disassembled.
INSPECTION
1) Disconnect connector from ISC actuator.
2) Check whether ISC actuator coil is open or short.
ISC actuator resistance at 20C (68F): 3 – 50 Ω
NOTE:
Above data should be used as reference value for determin-
ing whether coil is open or short only. ISC actuator resis-
tance may be out of above specified range even when ISC
actuator is normal.

FUEL PRESSURE REGULATOR
Removal
1) Relieve fuel pressure according to procedure described in sec-
tion 6.
2) Disconnect battery negative cable at battery.
3) Disconnect vacuum hose (3) from fuel pressure regulator (1).
4) Disconnect fuel return hose (2) from fuel pressure regulator (1).
CAUTION:
A small amount of fuel may be released when hose is dis-
connected. Cover hose to be disconnected with a shop
cloth.
5) Remove fuel pressure regulator.
CAUTION:
A small amount of fuel may be released when it is from
delivery pipe.
Place a shop cloth under delivery pipe so that released
fuel is absorbed in it.
Installation
For installation, reverse removal procedure and note following pre-
cautions.

Use new O-ring.

Apply thin coat of spindle oil or gasoline to O-ring to facilitate
installation.

With engine OFF and ignition switch ON, check for fuel leaks
around fuel line connection.

The ignition system used for this vehicle has an elec-
tronic ignition control system and consists of the fol-
lowing parts.

ECM
It detects the engine condition through the signals
from the sensors, determines the most suitable igni-
tion timing and time for electricity to flow to the pri-
mary coil and sends a signal to the power unit.

Power unit (Igniter)
It turns ON and OFF the primary current of the igni-
tion coil according to the signal from ECM.

Ignition coil
When the ignition coil primary current is turned OFF,
a high voltage is induced in the secondary winding.

Distributor
It distributes a high voltage current to each plug.
High-tension cords and spark plugs.

CMP sensor (Camshaft position Sensor)
Located in the distributor, it converts the crank angle
into voltage variation and sends it to ECM. For its
details, refer to Section 6E1.

TP sensor, ECT sensor and MAP sensor
For their details, refer to Section 6E.
In electronic ignition control system, the ECM is pro-
grammed for the best ignition timing under every en-
gine condition. Receiving signals which indicate the
engine condition from the sensors, e.g., engine revo-
lution, intake air pressure, coolant temperature, etc.,
it selects the most suitable ignition timing from its
memory and operates the power unit.
Thus ignition timing is controlled to yield the best en-
gine performance.
For more information, refer to Section 6E1.
SECTION 6F
IGNITION SYSTEM
WARNING:
For vehicles equipped with a Supplemental Inflatable Restraint Air Bag System:

Service on or around Air Bag System Components or Wiring must be performed only by an authorized
Suzuki dealer. Please observe all WARNINGS and SERVICE PRECAUTIONS in Section 9J under “On-
Vehicle Service” and the Air Bag System Component and Wiring Location view in Section 9J before
performing service on or around Air Bag System Components or Wiring. Failure to follow WARNINGS
could result in unintended air bag deployment or could render the air bag inoperative. Either of these
two conditions may result in severe injury.

SDM can maintain sufficient voltage to cause a deployment of air bags for up to 10 seconds after igni-
tion switch is turned to “LOCK” position, battery is disconnected or fuse powering SDM is removed.
Work must be started after 15 seconds from the time.

engine speed as compared with vehicle speed is not
within acceptable range.

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) Turn ignition switch OFF.
2) Clear DTC with ignition switch ON and warm up engine to normal operating temperature.
3) Shift selector lever to “D” range.
4) Start vehicle and increase vehicle speed to 40 – 55 km / h ( 25 – 35 mile / h) by depressing accelerator pedal half
a stroke.
5) Keep vehicle at above speed for 5 sec. or longer.
6) Increase vehicle speed to 75 – 90 km / h (45 – 55 mile / h) by depressing accelerator pedal half a stroke and keep
it at that speed for 5 sec. or longer.
7) Stop vehicle and check pending DTC and DTC.
