Fuel level sensor (sender gauge)
INSPECTION
Remove fuel pump assembly referring to Section 6C.
Use an ohmmeter to confirm that resistance of sender gauge unit
changes with change of float position.
If measured value is out of specification, replace fuel sender
gauge.

WARNING:
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:
For the descriptions (items) not found in this section, refer to the same section of the Service Manual
mentioned in FOREWORD of this manual.

Windshield Wipers
Front wiper and washer
Wiper motor
•As shown in the figure, use a 12 V battery to connect its (+)
terminal to terminal “A”, and its (–) terminal to “Black” lead
wire (2).
If motor (1) rotates at a low revolution speed of 45 to 55 rpm,
it is proper. For high speed check, connect battery (+) termi-
nal to terminal “B”, and its (–) terminal to “Black” lead wire
(2). If motor rotates at a high revolution speed of 67 to 83
rpm, it is proper.
•Testing automatic stop action.
a) Connect 12 V battery (+) terminal to terminal “A” of wiper
motor and (–) terminal to Black lead wire (2) and let the
motor turn.
b) Disconnect terminal “A” from battery, and let the motor
stop.
c) Connect terminal “A” and “D” with a jumper wire (3), and
connect terminal “C” to battery (+) terminal. Observe the
motor turns once again then stops at a given position.
d) Repeat a) through c) several times and inspect if the motor
stops at the given position every time.

Throttle Valve Opening Signal Circuit Check
Fig. for Step 2Step Action Yes No
1 Powertrain Control Module (PCM) Diagnostic Trouble Code
Check
1) Check PCM for DTC.
Is there a DTC related to throttle position sensor?Check and repair
TP sensor refer-
ring to Section 6-1.Go to Step 2.
2 Throttle Valve Opening Signal Circuit Check
1) Turn ignition switch ON.
2) Check voltage between terminal E61-4 of PCM connector
connected and ground.
Does voltage vary linearly according to throttle opening?Throttle valve
opening signal cir-
cuit is OK.Go to Step 3.
3 Supply Voltage Check
1) Disconnect connector from PCM with ignition switch OFF.
2) Check for proper connection to PCM at terminal E61-4.
3) If OK, connect “BLU” wire terminal of main relay to ground
with service wire.
4) Turn ignition switch ON.
5) Check voltage between E61-4 of PCM connector and
ground.
Is it 10 – 14 V?Check TP sensor
and circuits refer-
ring to Section 6-1.
If OK, substitute a
known-good PCM
and recheck.Check “GRY”
wire for open
and short. If OK,
proceed to
cruise control
module power
and ground cir-
cuits check.

Cruise Cable Play Inspection and Adjustment
INSPECTION AND ADJUSTMENT
1) Remove actuator cap.
2) With actuator lever (1) returned at original position (2)
(Where lever does not move clockwise any further), check
cruise cable for play.
If it is out of specification, adjust it as follows
Cruise Cable play “a” :
1 – 2 mm (0.04 – 0.08 in.)
3) Loosen cable lock nut (3).
4) Adjust cable play to specified value by turning adjusting nut
(4).
5) Tighten lock nut (3) securely after adjustment.
