FUEL CUT OPERATION
Inspection
NOTE:
Before inspection, check to make sure that gear shift lever is
in neutral position (with A / T model, selector lever in “P”
range), A / C is OFF and that parking brake lever is pulled all the
way up.
1) Warm up engine to normal operating temperature.
2) While listening to sound of injector (1) by using sound scope (2)
or such, increase engine speed to higher than 3,000 r / min.
3) Check to make sure that sound to indicate operation of injector
stops when throttle valve is closed instantly and it is heard again
when engine speed is reduced to less than about 2,000 r / min.
RADIATOR FAN CONTROL SYSTEM
System Inspection
WARNING:
Keep hands, tools, and clothing away from engine cooling
fan to help prevent personal injury. This fan is electric and
can come on whether or not the engine is running. The fan
can start automatically in response to the ECT sensor with
the ignition switch in the ON position.
Check system for operation referring to Flow Table B-8 in Section
6.
If radiator fan fails to operate properly, check relay, radiator fan and
electrical circuit.
Radiator Fan
Inspection
1) Check continuity between each two terminals.
If there is no continuity, replace radiator fan motor.

2) Connect battery (1) to radiator fan motor coupler (2) as shown
in figure, then check that the radiator fan motor operates
smoothly.
If radiator fan motor does not operate smoothly, replace motor.
EMISSION CONTROL SYSTEM
EGR SYSTEM
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 KPH

Engine coolant temp.
80C

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 pas-
sage, stuck or faulty EGR valve, poor performance of ECT sen-
sor 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 coupler.
3) Remove EGR valve and gasket from intake manifold.

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.

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.

NOTE:

The operation distance of this system varies depending on the position where the transmitter is oper-
ated, at the front side, the rear side or the lateral side. The distance can be affected by radio noises from
a TV station, a power plant, a broadcasting station and so forth.

ECT SENSOR
INSPECTION
1) Warm up ECT sensor (1) observing resistance between sensor
terminal (2) and sensor unit (1). Resistance should be de-
creased with increase of its temperature.
2) Check resistance between sensor terminal (2) and sensor unit
(1). If check result is not as specified below, replace sensor.
