Overview
PTO Operation
The 3500/4500/5500 Dodge Chassis Cab vehicle, when equipped with either the automatic Aisin 6
speed or manual G56 6 speed transmissions, will allow for an aftermarket upfit with a transmission
driven PTO (Power Take-Off). The customer will have the ability to operate the PTO in either a
“stationary” or “mobile” mode. The vehicles will be factory set to the “stationary” mode. In order to select
the “mobile” mode a Daimler Chrysler Dealership is required to modify the vehicles settings using their
proprietary Dealer service tool.
Stationary Mode
To operate the PTO in this mode the vehicle must meet the following conditions:
■
Be in park positions (vehicles equipped with automatic transmission)
■
Up fitter provided (on/off) switch has been activated
■
Parking brake applied (vehicles equipped with manual transmission)
■
Vehicle must be running
■
No vehicle, brake or clutch switch faults present
■
PTO must be correctly installed using the vehicle provided circuits
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 operate the feature using the cruise
control switches the customer must first activate the up fitter provided on/off switch. Next, the cruise
control “on” switch is selected. Following this step the “set” switch must be depressed. The vehicle is
now in the PTO mode and is ready for use. In order to increase or decrease the engine idle speed, to
optimize the PTO function, the “accel” and “decel” cruise switches can be used respectively. To
disengage PTO operation and return to standard vehicle operation simply turn the up fitter provided on/
off switch to the off position.
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 at-
tention 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.
