Engine Protection; California Engine Idle Limiting - Detroit Diesel MBE 900 Operator's Manual

Engine brakes will supply braking
power even when in Cruise Control.
The MCM will control the amount
of engine braking with respect to
the Cruise Control set speed. The
maximum amount of braking (low,
medium, high) is selected with the
dash switches.

Engine Protection

The DDEC engine protection
system monitors all engine sensors
and electronic components, and
recognizes system malfunctions. If
a critical fault is detected, the AWL
(Check Engine) and RSL (Stop
Engine) illuminate. The malfunction
codes are logged into the MCM's
memory.
The standard parameters which are
monitored for engine protection
are: low coolant level, high coolant
temperature, low oil pressure, and
high oil temperature.
This system features a 30-second,
stepped-power shutdown sequence
or an immediate speed reduction
without shutdown in the event a major
engine malfunction occurs, such as
low oil pressure, high oil or coolant
temperature, or low coolant level.

PERSONAL INJURY
To avoid injury from engine
shutdown in an unsafe situation,
ensure the operator knows how
to override the stop engine
condition on a DDEC-equipped
unit.
Engines equipped with the
power-down/shutdown option have
a system override button or switch
to allow engine operation for a
short period of time. Using the
override button so the engine does
not shutdown in 30 seconds but
operates for an extended period
may result in engine damage.

California Engine Idle Limiting

In order to meet the California Engine
Idle Limiting Standard, an engine
idle shutdown feature has been built
into the DDEC VI Engine Control
Strategy. When the California Engine
Idle Limiting feature is enabled, the
engine will generally shut down after
five minutes of continuous idling
when the transmission is in neutral
or park and the parking brake is set
or after fifteen minutes when the
transmission is in neutral or park and
