6E2-44 ENGINE AND EMISSION CONTROL SYSTEM (SEQUENTIAL MULTIPORT FUEL INJECTION FOR H27 ENGINE)
Emission Control System
EGR system (if equipped)
EGR SYSTEM INSPECTION (USING SUZUKI SCAN TOOL)
1) Connect SUZUKI scan tool to data link connector (DLC) (1)
with ignition switch OFF.
Special tool
(A) : SUZUKI scan tool
2) Start engine and warm up it to normal operating tempera-
ture.
3) With engine idling (without depressing accelerator pedal),
open EGR valve by using “MISC. TEST” mode.
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.
REMOVAL
1) Disconnect negative (–) cable at battery.
2) Disconnect EGR valve coupler.
3) Remove wire harness bracket from intake collector.
4) Remove EGR valve (5) and gasket from intake collector.NOTE:
For operation procedure of cartridge, refer to its car-
tridge operator's manual.

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).
