ENGINE WARNING PROTECTION SYSTEM (EWPS)
The Engine Warning Protection System (EWPS) warns the
operator of engine conditions that can damage the engine.
Optional engine shutdown is available and is activated if one or
more critical conditions are detected.
The Standard Warning System is the base system in which
all engines are equipped. If one of these faults are detected,
the ECM will illuminate the Amber Warning Lamp (AWL), set a
corresponding Diagnostic Trouble Code (DTC), and de-rate the
engine.
