DDEC VI SYSTEM

DDEC Features

DDEC offers a variety of features and
options designed to warn the operator
of an engine malfunction.
Options can range from warning panel
lights to automatic reduction in engine
power followed by automatic engine
shutdown.
DDEC has the ability to perform
diagnostics for self-checks and
continuous monitoring of other
system components.
Depending on the application,
DDEC can monitor oil temperature,
coolant temperature, oil pressure, fuel
pressure, coolant level and remote
sensors (if used).
DDEC connects to the AWL (Check
Engine) and the RSL (Stop Engine) to
provide a visual warning of a system
malfunction.

Cruise Control

Cruise Control is available with any
DDEC engine. Cruise Control will
operate in either Engine or Vehicle
Speed Mode and maintain a targeted
speed (MPH or RPM) by increasing or
decreasing fueling. The targeted speed
can be selected and adjusted with
dash-mounted switches. See Figure
18.

Cruise Control may also be
programmed to permit fast idle
using the Cruise Control switches.
With the engine at normal idle,
transmission in neutral and service
brakes on, depress the SPD CNTL
Switch, and use the RSM/ACC
Switch. The engine rpm should
increase to a pre-defined speed. The
engine rpm can be raised or lowered
from this point using the SET/CST
and RSM/ACC switches.
Cruise Control will maintain the set
speed under normal road and load
conditions.
