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.

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.

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.

5) Measure secondary coil for resistance.
Secondary coil resistance : 7.6 – 10.2 kΩ at 20C, 68F
If resistance is out of specification, replace ignition coil assem-
bly.
6) Install ignition coil assembly.
7) Tighten ignition coil bolts, and then connect ignition coil coupler.
8) Install high-tension cord to ignition coil assembly while gripping
its cap.

IGNITION TIMING
NOTE:

Ignition timing is not adjustable. If ignition timing is out of
specification, check system related parts.

Before starting engine, place transmission gear shift lever in
“Neutral” (shift selector lever to “P” range for A / T model),
and set parking brake.
INSPECTION
1) Connect SUZUKI scan tool to DLC with ignition switch OFF.
Special Tool
(A): 09931-76011 (SUZUKI scan tool)
(B): Mass storage cartridge
(C): 09931-76030 (16 / 14 pin DLC cable)

3) Make sure that all of electrical loads except ignition are switched
off.
4) Check to be sure that idle speed is within specification.

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

Torque converter malfunction
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.

7B-32 AUTOMATIC TRANSMISSION (3 A / T) (VEHICLE WITH WU-TWC)
STALL TEST
This test is to check overall performance of automatic transmission
and engine by measuring stall speed at D and R ranges.
Be sure to perform this test only when transmission fluid is at normal
operating temperature (70–80C / 158–176F) and its level is be-
tween FULL HOT and LOW HOT. (Refer to “Fluid level” in this sec-
tion.)
CAUTION:
Do not run engine at stall more than 5 seconds continuous-
ly, for oil temperature may rise excessively high.
1) Install tachometer.
2) Apply parking brake and block vehicle wheels.
3) Start engine with selector lever shifted to P range.
4) Depress brake pedal.
5) Shift selector lever to D range and depress accelerator pedal ful-
ly while watching tachometer. Read engine rpm quickly when it
has become constant (stall speed).
6) Release accelerator pedal immediately after stall speed is
checked.
7) In the same way, check stall speed at R range.
8) Stall speed should be within following specification.
Stall speed: 2,500 – 2,900 r / min
(For both G10 and G13 engine models)
9) Possible causes for out-of-specification stall speed are as fol-
lows. Check each part which is suspected to be the cause.

AUTOMATIC TRANSMISSION (3 A / T) (VEHICLE WITH WU-TWC) 7B-33
LINE PRESSURE TEST
This test is to check oil pressure system for operation by measuring
oil pressure in oil pressure line. Make sure to perform this test only
when transmission fluid is at normal operating temperature.
NOTE:

Make sure that transmission fluid level is between FULL HOT
and LOW HOT marks on oil level gauge at normal operating
temperature which corresponds to 70–80C (155–176F) of
fluid. (Refer to “Fluid level” in this section.)

Check that transmission is free from fluid leakage.
1) With engine at stop, remove plug and connect oil pressure
gauge to plug hole.
Special Tool
(A): 09925-37811-001
2) Install tachometer.
3) Apply parking brake and block vehicle wheels.
4) With selector lever shifted to P range, start engine.
5) Depress brake pedal fully.
6) Shift selector lever to D range and check oil pressure with engine
running at idling speed and at stall speed respectively.
7) Repeat the same check as in step 6) with selector lever shifted
to R range.
CAUTION:
Do not run engine at stall more than 5 seconds continu-
ously, for oil temperature may rise excessively high.
8) If line pressure is within respective specification in table below,
oil pressure system is in good condition.
