Connect GDS to Data Link Connector (DLC).
Warm engine up to normal operating temperature.
Turn "OFF" electrical devices and A/C.
Monitor "AIR MASS PERCYLINDER" parameter on the GDS.
Specification : When Electric EGR control valve does not operate 5% duty) at idle : 340mg/st ± 50 mg/st
When Electric EGR control valve operates(Approx. 45% duty) at idle : 200ms/st ± 50 mg/st
Fig.1) Check if "AIR MASS PERCYLINDER"l is 340mg/st ± 50mg/st without EEGR operation at warm idle (Electric EGR control valve 5% duty)
Fig.2) Check if "AIR MASS PERCYLINDER"l is 200mg/st ± 50mg/st with EEGR operation at warm idle (Electric EGR control valve approx. 45% duty)
※ Electric EGR control valve operates as decelerating after rapid acceleration when idle EEGR does not operate, Electric EGR control valve operating duty decreases as time goes by. This controlling process lasts for about 1 min. and EElectric EGR control valve turns "OFF" (duty 5% ) after 1 min.
