Line 75: − − === DDEC I Schematics === − [[File:DDEC I Schematic Diagram.png|thumb|DDEC I Schematic Diagram]]DDEC I controls the timing and amount of fuel injected into each cylinder. The system also monitors several engine functions using various sensors that send electrical signals to the main Electronic Control Module (ECM). The ECM uses this information to send a command pulse to the Electronic Distributor Unit (EDU). The EDU functions as the high current switching unit for actuation of the Electronic Unit Injector (EUI) solenoids. The ECM also has the ability to limit or shut down the engine completely (depending on option selection) in the case of damaging engine conditions, such as low oil pressure, low coolant level, or high oil temperature.

|'''Low Oil Pressure''' - Engine running wf th the 011 pressure less than the limit (different limits at different RPM's) for 7 seconds. This fault will cause both the "Stop Engine<nowiki>''</nowiki> and "Check Engine" light to turn on, and will power down (and eventually shutdown) the engine if the engine protection system is equipped with the shutdown feature.
