Remote Engine Shutdown

Control

The vehicle’s PTO system allows for

remote engine shutdown while

operating in the stationary PTO

mode. This feature has the following

functions:

.

Engine shutdown using the

operator remote switch: The

vehicle wiring system provides

remote engine shutdown switch

connections, which are

accessed through the PTO

upfitter connector.

.

Timed auto-engine shutdown:

The timed auto-engine shutdown

feature provides the means to

shut down the engine

automatically after a predefined

time. PTO must be operational

for this function to be active.

.

Engine shutdown based on

critical engine conditions: The

engine will be shut down when

PTO is operating if a critical

engine condition is detected by

the vehicle system (i.e., low oil,

low oil pressure, hot engine, hot

transmission, low fuel, diesel

particulate filter regeneration).

If PTO operation is continued

when critical engine conditions

are present, a horn chirp

warning will occur after two to

five minutes. The engine will be

shut down two minutes after the

horn warning. The operator can

re-start the engine with the

ignition key. The above horn

warning and engine shutdown

will again occur if the critical

engine condition is still present.

Prolonged or Extended PTO

Operation

While operating the vehicle in

stationary PTO mode, the Diesel

Particulate Filter (DPF) will continue

to filter the exhaust and accumulate

soot. The engine control system,

depending on the speed and load

being applied by the PTO, may not

be able to generate enough energy

or adequate heat needed to clean or

regenerate the DPF. Continued

operation under conditions that do

not allow effective regeneration or

cleaning will eventually plug the

DPF and result in reduced power.

The ENGINE POWER IS

REDUCED Driver Information

Center (DIC) message and

malfunction indicator lamp will be

displayed, and dealer service will be

required to return the vehicle to

normal, full power operation. To

prevent this from occurring,

frequently monitor the vehicle during

PTO operation. If the DIC message

is displayed during PTO operation,

see Diesel Particulate Filter on

page 9-12 for information on how to

clean or regenerate the DPF. Also

see “Remote Engine Shutdown

Control” earlier in this section.
