Detroit Diesel Electronic Control System Features
6.1
Changing the Idle Speed
The idle speed can be variable if the parameters in the CPC are set to the default range. Change the idle speed as follows:
1.
Turn the cruise control switch to the ON position.
2.
To increase the idle speed, push the RSM/ACC switch until the idle reaches the desired rpm.
3.
To decrease the idle speed, push the SET/CST switch until the idle reaches the desired rpm.
6.2
Stop Engine Override Option
The Stop Engine Override Option is used for a momentary override. The electronic engine control system will record the
number of times the override is activated after an engine fault occurs.
6.3
Engine Protection
The electronic engine control protection system monitors all engine sensors, 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 MR2'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.
WARNING: 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.
NOTICE:
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 shut down in
30 seconds but operates for an extended period may result in engine damage.
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.
