For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” 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 of 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).
NOTE:
Whether following systems (parts) are used in the particular vehicle or not depends on specifications.
Be sure to bear this in mind when performing service work.
EGR valve
Heated oxygen sensor (s) or CO adjusting resistor
Three way catalytic converter (TWC) and warm up three-way catalytic converter (WU-TWC)

Fuel Delivery System
The fuel delivery system consists of the fuel tank (1), fuel pump (2), fuel filter (3), fuel pressure regulator (11),
delivery pipe (9) and fuel injectors (10).
The fuel in the fuel tank is pumped up by the fuel pump, filtered by the fuel filter and fed under pressure to each
injector through the delivery pipe.
As the fuel pressure applied to the injector (the fuel pressure in the fuel feed line) is always kept a certain
amount higher than the pressure in the intake manifold by the fuel pressure regulator, the fuel is injected into the
intake port of the cylinder head when the injector open according to the injection signal from ECM.
The fuel relieved by the fuel pressure regulator returns through the fuel return line (8) to the fuel tank.
Fuel pump
An in-tank type electric pump has been adopted for the fuel pump
(1). Incorporated in the pump assembly are;
Tank pressure control valve (2) which keeps the pressure in
the fuel tank constant, and prevents the fuel from spouting
and tank itself from being deformed.
Relief valve (3) which prevents the pressure in tank from ris-
ing excessively.
Fuel cut valve (4) which closes as the float rises so that the
fuel will not enter the canister when the fuel level in the tank
rises high depending on the fuel level in the tank and the
vehicle tilt angle.
Also, a fuel filter (5) is included and a fuel level gauge (6) is
attached.

2) Connect battery (3) to A/C condenser fan motor coupler (2)
as shown in figure, then check that the A/C condenser fan
motor (1) operates smoothly.
If A/C condenser fan motor does not operate smoothly,
replace motor.

THROTTLE VALVE OPENING SIGNAL INSPECTION
Check throttle valve opening (throttle position) signal referring to
step 1 of “DTC P1700 (No.32 or 33) Flow Table” in Section 7B.
If check result is not satisfactory, check each wire harness, circuit
connections and TP sensor.
ENGINE COOLANT TEMP. SIGNAL INSPECTION
Check engine coolant temp. signal referring to step 1 of “DTC
P1709 (No.51) Flow Table” in Section 7B.
If check result is not satisfactory, check each wire harness, circuit
connection and ECT sensor.

SYSTEM INSPECTION (USING SUZUKI SCAN TOOL)
1) Connect SUZUKI scan tool to DLC with ignition switch OFF.
2) Turn ignition switch ON and then select “DATA LIST” mode
on scan tool.
3) Make sure that vehicle condition is as following.
Vehicle speed = 0 km/h (0 KPH)
Engine speed ≤ 3000 rpm
4) Clear DTC by using “CLEAR INFO” mode.
5) With engine idling (without depressing accelerator pedal),
open EGR valve by using “STEP EGR” mode in “MISC
TEST” menu.
In this state, according as EGR valve opening increases
engine idle speed drops. If not, possible cause is clogged
EGR gas passage, stuck or faulty EGR valve, poor perfor-
mance of ECT sensor or TP sensor or DTC and/or pending
DTC is (are) stored in ECM memory.

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
It detects the engine and vehicle conditions through the signals from the sensors, determines the most suit-
able 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
according to the signal from ECM. When the current flow to the primary coil is turned OFF, a high voltage is
induced 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 identifies the specific cylinder whose piston is in the compression
stroke, detects the crank angle and adjust initial ignition timing automatically.
TP sensor, ECT sensor, MAP sensor and other sensors/switches
Refer to “Electronic Control System” in Section 6E 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 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 simulta-
neously. 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.
