Group 28 Design and Function
Other Functions
The EECU guides the EUIs based on the following ”con-
trol functions.”
Smoke limitation — To prevent injecting too much fuel
into the cylinder, the EECU checks:
•
Boost pressure
•
Engine speed
•
Boost air temperature
PTO engine speed — The engine can be kept at a con-
stant rpm level that is at least 100 rpm greater than low
idle and less than high idle.
Cruise control — The engine can be set to maintain a
constant speed between 48 km/h (30 mph) and 140
km/h (87 mph). For the cruise control mode to function,
the following conditions must be satisfied:
•
Cruise control in ON position.
•
Brake pedal must not be depressed.
•
Clutch pedal must not be depressed.
Speed limitation — The EECU can be programmed to
limit the maximum speed up to 140 km/h (87 mph). A
fault on the sensor signal and/or a faulty cable to the
EECU generates a fault code.
Differentiated speed limitation — This mode is avail-
able as an option. It limits the speed to various levels
depending on the gear selected. In other words, each
gear has a maximum speed.
