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 the FOREWORD of this manual.

On-vehicle Service
Fuel Meter/Fuel Gauge Unit
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.
Fuel level sensor specification :
Float Position Resistance (Ω
ΩΩ Ω)
“a”53.6 mm
(2.11 in.)6 – 8
“b”143.1 mm
(5.63 in.)28 – 36
“c”256.9 mm
(10.11 in.)90 – 100
