Monitor GDS Data

1. Connect GDS to DLC(Data Link Cable).
2. Warm up the engine to normal operating temperature.
3. Monitor "FPS" parameter on GDS.








Fig.1) Check the change under the condition of acceleration and deceleration.
Fig.2) Check the 'Angle to Close FPR' and 'Angle to Open FPR' under idle state
Examine the fuel pressure checking the change of rail pressure and 'Angle to Close FPR' and 'Angle to Open FPR'.
4. Is the "FPS" parameter displayed correctly?
