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.
Reference current data of A/C condenser fan motor
Approx. 6.7 – 8.3 A at 12 V
Output signals of throttle valve opening and engine
coolant temp. (Vehicle with A/T only)
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.
Emission Control System
EGR system (If equipped)
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.

REMOVAL
1) Disconnect negative cable at battery.
2) Disconnect EGR valve connector.
3) Remove EGR pipe.
4) Remove EGR valve and gasket from cylinder head.
INSPECTION
1) Check resistance between following terminals of EGR valve
(1) in each pair.
If found faulty, replace EGR valve assembly.
EGR valve resistance
2) Remove carbon from EGR valve (1) gas passage.
3) Inspect valve (2), valve seat (3) and rod for fault, cracks,
bend or other damage.
If found faulty, replace EGR valve assembly.
INSTALLATION
Reverse removal procedure noting following.
Clean mating surface of valve and cylinder head.
Use new gaskets.

NOTE:
Do not use any sharp-edged tool to remove carbon.
Be careful not to damage or bend EGR valve, valve seat
and rod.
NOTE:
Before inspection, check to make sure that gear shift
lever is in neutral position (with A/T model, selector lever
in “P” range) and that parking brake lever is pulled all the
way up.
