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.

6F1-2 IGNITION SYSTEM (SFI FOR G13)
GENERAL DESCRIPTION
The ignition system is an electronic (distributorless) ignition system. It consists of the parts as described below and
has an electronic ignition control system.

ECM (PCM)
It detects the engine and vehicle conditions through the signals from the sensors, determines the most suitable
ignition timing and time for electricity to flow to the primary coil and sends a signal to the ignitor (power unit) in
the ignition coil assembly.

Ignition coil assembly (including an ignitor)
The ignition coil assembly has a built-in ignitor which turns ON and OFF the current flow to the primary coil accord-
ing to the signal from ECM (PCM). When the current flow to the primary coil is turned OFF, a high voltage is in-
duced in the secondary coil.

High tension cords and spark plugs.

CMP sensor (Camshaft position sensor) and CKP sensor (Crankshaft position sensor)
Using signals from these sensors, ECM (PCM) identifies the specific cylinder whose piston is in the compression
stroke and detects the crank angle.

TP sensor, ECT sensor, MAP sensor and other sensors / switches
Refer to section 6E2 for details.
Although this ignition system does not have a distributor, it has two ignition coil assemblies (one is for No.1 and
No.4 spark plugs and the other is for No.2 and No.3 spark plugs). When an ignition signal is sent from ECM (PCM)
to the ignitor in the ignition coil assembly for No.1 and No.4 spark plugs, a high voltage is induced in the secondary
coil and that passes through the high-tension cords and causes No.1 and No.4 spark plugs to spark simultaneously.
Likewise, when an ignition signal is sent to the ignitor in the other ignition coil assembly, No.2 and No.3 spark plugs
spark simultaneously.

7B-8 AUTOMATIC TRANSMISSION (3 A / T) (VEHICLE WITH WU-TWC)
TRANSMISSION RANGE SENSOR (SHIFT SWITCH)
Being linked with the selector lever, this sensor changes selector
lever positions into electric signals and send them to the engine
control module. The contact points of this sensor for P and N ranges
are also connected with the starting motor circuit.
So when the selector lever is shifted to the P or N range position,
the contact points for P or N range are connected and cause the
starting motor to operate by turning the starter switch ON.
When the selector lever is in any other position than P and N
ranges, the sensor remains OFF and therefore the starting motor
cannot be operated, that is, the engine cannot be started.
Also, as its contact point for R range is connected with the backup
lamp circuit, only when the selector lever is shifted to R range, the
contact point contacts to light the backup lamp.
DIRECT CLUTCH AND 2ND BRAKE SOLENOID
VALVES
These solenoid valves are mounted on the valve body. They are
turned ON and OFF by the signals from the engine control module
and actuate each shift valve (1 – 2 and 2 – 3 valves) so as to control
transmission gear shift.
Shift solenoid-B (2nd brake solenoid valve) operates 1 – 2 shift
valve, and shift solenoid-A (direct clutch solenoid valve) does 2 –
3 shift valve.

BODY ELECTRICAL SYSTEM 8-3
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.

Ignition signal

With the diagnosis switch terminal of monitor coupler for ECM not
grounded, the ignition switch turned ON (but the engine at stop) and
regardless of the condition of the engine and emission control sys-
tem, ECM indicates whether a trouble has occurred in the immobi-
lizer control system or not by causing the malfunction indicator lamp
to flash or turn ON.
Malfunction indicator lamp is ON:
No trouble exists in the immobilizer control system.
Malfunction indicator lamp is flashing:
ECM or Immobilizer Control Module has detected some trouble in
the immobilizer control system.
NOTE:
As soon as the ignition switch is turned ON, ECM and Immobi-
lizer Control Module diagnose if a trouble has occurred in the
immobilizer control system. While the diagnosis is being
made, the malfunction indicator lamp stays ON and if the diag-
nosis result is “abnormal”, it immediately changes to flashing
but if the result is “normal”, it remains ON. Diagnosis takes
about 3 seconds at maximum.
