Engine Monitoring Mode
OEM
Description:
The Engine Monitoring System provides built-in engine
monitoring that can detect abnormal oil pressure,
high intake manifold air temperature, high coolant
temperature and if an optional Coolant Level Sensor is
installed, coolant level. Typically, an additional Warning
lamp is installed in the dash for driver notifi cation. The
Engine Monitoring System can be programmed to one of
four different settings:
Off - Monitoring System is Off
Warning - The Warning Lamp on the dash turns On
Derate - The Warning Lamp on the dash turns On and
engine power is reduced
Shutdown - The Warning Lamp on the dash turns On,
engine power is reduced, then the engine shuts
down.

Abnormal Oil Pressure - Engine oil pressure is
monitored for all rpm and loads. For example, this
can help prevent excessive damage if the engine
is started without oil or if the oil pressure is too
low during a heavy pull. Power and speed (engine
rpm) are limited during the derate period following
the warning if the Derate or Shutdown settings
are programmed. If the low oil pressure condition
persists, the engine will shutdown if the Shutdown
setting is active.
High Coolant Temperature - Engine coolant tempera-
ture is monitored to provide gradual power reduc-
tions as the coolant temperature increases above
the acceptable limits if the Engine Monitoring
Mode is programmed to Derate or Shutdown. The
driver can downshift to increase rpm and coolant
fl ow in this mode. If the high coolant temperature
condition persists, and the Engine Monitoring
Mode parameter is programmed to Shutdown, the
engine will shutdown.
