DD Platform EuroIV Operators Manual
The engine will only operate at reduced rpm until the battery voltage reaches a
point where the MCM will no longer function and the engine shuts down.
Should the AWL (Check Engine) come on for any reason, the vehicle can still be
operated and the driver can proceed to the required destination. This condition
should be reported to an authorized Detroit™ distributor or dealer.
NOTICE: When the RSL (Stop Engine) comes on, the system has detected
a major malfunction in the engine that requires immediate attention. It is
the operator's responsibility to shut down the engine to avoid serious
damage.
The engine can be configured to give a warning only, to ramp down (reduce power)
or to shut down. Ramp down will reduce engine rpm to a predetermined speed, but
will not shut down the engine. With the 30-second shutdown option, the engine will
begin a 30-second, stepped power down sequence until it shuts down completely.
The "Stop Engine Override" feature can be activated in the case where the vehicle
is operating in a critical location.
Stop Engine Override Switch
This feature allows the operator to override the automatic stop engine sequence.
This is done by pressing the Stop Engine Override Switch every 15 to 20 seconds
to prevent engine shutdown from occurring.
