Connect GDS with 'DATA LINK CONNECTOR' (DLC).

Warm engine up to normal operating temperature.

Warm engine up to normal operating temperature.

Monitor "FUEL QUANTITY" parameter on the GDS.

Fig.1) Fuel injection amount at idle.

Fig.2) Fuel injection amount at 4000 rpm.

☞ "FUEL QUANTITY" is a sample data from randomly selected a injector among cylinders. Therefore, thoroughly check all the symptom through the "compression pressure and fuel line" with GDS.

☞ Initial operating pressure at starting : 120bar, operating pressure right after starting : 230 ~ 1600bar.
