SPECIFICATIONS DIFFERENT FROM ABS
CONTROL MODULE SPECIFICATIONS .. 5E-22 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:
All brake fasteners are important attaching parts in that they could affect the performance of vital
parts and systems, and/or could result in major repair expense. They must be replaced with one of
same part number or with an equivalent part if replacement becomes necessary. Do not use a replace-
ment part of lesser quality or substitute design. Torque values must be used as specified during reas-
sembly to assure proper retention of all parts. There is to be no welding as it may result in extensive
damage and weakening of the metal.

ENGINE GENERAL INFORMATION AND DIAGNOSIS 6-5
PRECAUTION ON FUEL SYSTEM SERVICE
Work must be done with no smoking, in a well-ventilated
area and away from any open flames.
As fuel feed line (between fuel pump and fuel delivery pipe)
is still under high fuel pressure even after engine was
stopped, loosening or disconnecting fuel feed line directly
may cause dangerous spout of fuel to occur where loosened
or disconnected.
Before loosening or disconnecting fuel feed line, make sure
to release fuel pressure according to “FUEL PRESSURE
RELIEF PROCEDURE”. A small amount of fuel may be
released after the fuel line is disconnected. In order to
reduce the chance of personal injury, cover the fitting to be
disconnected with a shop cloth. Put that cloth in an approved
container when disconnection is completed.
Never run engine with fuel pump relay disconnected when
engine and exhaust system are hot.
Fuel or fuel vapor hose connection varies with each type of
pipe. When reconnecting fuel or fuel vapor hose, be sure to
connect and clamp each hose correctly referring to figure
Hose Connection.
After connecting, make sure that it has no twist or kink.
When installing injector or fuel delivery pipe, lubricate its O-
ring with spindle oil or gasoline.
When connecting fuel pipe flare nut, first tighten flare nut by
hand and then tighten it to specified torque.
[A] : With short pipe, fit hose as far as it reaches pipe joint as shown.
[B] : With following type pipe, fit hose as far as its peripheral projection as shown.
[C] : With bent pipe, fit hose as its bent part as shown or till pipe is about 20 to 30 mm
(0.79–1.18 in.) into the hose.
[D] : With straight pipe, fit hose till pipe is, about 20 to 30 mm (0.79–1.18 in.) into the
hose.
