• No vehicle, brake or clutch switch faults present.
• PTO must be correctly installed using the vehicle

provided circuits.

The Electronic Vehicle Information Center (EVIC) will

display a ЉPTO OnЉ message for five seconds if the above

conditions are met. Otherwise, the EVIC will display a

message ЉTo Operate PTO Shift To ParkЉ indicating what

operator action should be taken to engage the PTO mode.
The customer has the choice to operate the PTO by

utilizing the cruise control switches or by utilizing a

remote control (provided by the PTO supplier). To oper-

ate the feature using the cruise control switches, the

customer must first activate the PTO switch which will

turn on the PTO. In order to increase or decrease the

engine idle speed, to optimize the PTO function, the

“RESUME/ACCEL” and “DECEL” cruise switches can

be used respectively. To disengage PTO operation and

return to “standard vehicle operation” simply toggle the

PTO switch to the OFF position.

The torque converter clutch (TCC) will automatically

engage at engine speeds above 1,200 RPM (engine speed)

in PTO stationary mode. Once engaged, the TCC will

remain applied and will not disengage until the engine

speed falls below 1,000 RPM. TCC engagement is desir-

able for certain types of PTO applications (Automatic

Transmission Only).
To operate the PTO via a remote switch, the customer

must make sure the above conditions are met. It is vital

for proper operation that the PTO and remote have been

installed correctly, paying special attention to ensure the

vehicle provided wiring has been connected properly.

This is the responsibility of the installer of the PTO and

switches/remote system. It is the responsibility of the

PTO manufacturer to ensure that their electrical (switches

and remote) system is compatible with the vehicle’s

electrical architecture and software functionality.
