EGR System Inspection
1) Connect SUZUKI scan tool to data link connector
(DLC) with ignition switch turned OFF.
2) Turn ON ignition switch and erase DTC using
"CLEAR DTC" in "TROUBLE CODES" menu.
3) Start engine and warm it up to normal operating
temperature, then select "DATA LIST" mode on scan
tool.
4) Make sure that vehicle condition is as follows.
• Vehicle speed = 0 km/h (0 KPH)
• Engine speed ≤ 900 rpm
• Engine coolant temp. ≥ 90 °C, 164 °F
5) With engine idling (without depressing accelerator
pedal), open EGR valve by using "STEP EGR" mode
in "MISC TEST" menu. In this state, as EGR valve
opening increases engine idle speed drops. If not,
possible cause is clogged EGR gas passage, stuck
or faulty EGR valve.
EVAP Canister Purge Inspection
NOTE
Before inspection, check to make sure that gear shift lever is in neutral position (with A/T model,
selector lever in "P" range) and that parking brake lever is pulled all the way up.
1) Disconnect purge hose (1) from EVAP canister (2).
2) Place finger against the end of disconnected hose and check that vacuum is not felt there when engine is cool and
running at idle speed. If check result is not satisfactory, check EVAP canister purge valve, wire harness and ECM.
