Monitor GDS Data
1.

Monitoring rail pressure data

(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 "FUEL PRESSURE MEASURED", "FUEL PRESSURE-TARGET", "RAIL PRESS. REGULATOR1", "INJ. PUMP REGULATOR" parameter on the GDS.
