Emission Control System
EGR system (If equipped)
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 km/h (0 KPH)
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 passage, stuck or faulty EGR valve, poor perfor-
mance of ECT sensor or TP sensor or DTC and/or pending
DTC is (are) stored in ECM memory.
