sor.
2) Using ohmmeter, check resistance between terminals under
each condition given in table below.

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.

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.

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.

KEYLESS ENTRY SYSTEM (IF EQUIPPED)
The keyless entry system uses radio wave. When the button on the transmitter is pressed, a signal is transmitted
in the form of radio wave to the receiver. Then the signal causes the door lock controller to lock and unlock the door.
The door locks can not operated with the transmitter when either of the following conditions applies.

For 2 seconds after the ignition switch is turned from ON to OFF position.

The ignition switch is at ON or START position.

Any door is open.

REPLACEMENT OF THE BATTERY
If the transmitter becomes unreliable, replace the battery.
As the battery power is consumed, the operation distance will be
shorter.
1) Put the edge of a coin or a flat blade screw driver in the slot of
the transmitter and pry it open.
2) Replace the battery (lithium disc-type CR2025 or equivalent) so
its (+) terminal faces the “+” mark of the transmitter.
CAUTION:
Use care not to allow grease or dirt to be attached on the
printed circuit board and the battery.
3) Close the transmitter firmly.
4) Make sure the door locks can be operated with the transmitter.
NOTE:

To prevent theft, be sure to break the transmitter before
discarding it.

Dispose of the used battery properly according to appli-
cable rules or regulations. Do not dispose of lithium bat-
teries with ordinary household trash.
