1.

Connect GDS to Data Link Connector (DLC).

2.

Warm engine up to normal operating temperature.

3.

Turn "OFF" electrical devices and A/C.

4.

Monitor "AIR MASS FLOW PER CYLINDER" 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 FLOW PER CYLINDER"l is 340mg/st ± 50mg/st without EEGR operation at warm idle (Electric EGR control valve 5% duty)

Fig.2) Check if "AIR MASS FLOW PER CYLINDER"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 Electric EGR control valve turns "OFF" (duty 5% ) after 1 min.
