PTO Operation & Installation Guide
PTO Operation
The 3500/4500/5500 Ram Chassis Cab vehicle, when equipped with either the automatic
Aisin 6spd or manual G-56 6spd 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 Chrysler Group LLC
Dealership is required to modify the vehicles settings using their proprietary Dealer
service tool. Under normal operation the vehicle will go to a 900 rpm when PTO is
engaged. By utilizing the cruise switches the idle speed can then be adjusted to between
900 and 2000 rpm's.
Stationary Mode
This feature interacts with the transmission to utilize an auxiliary shaft to drive
equipment. Activated by a switch inside the cab, this feature operates only when the
vehicle is stationary. The input is switched to ground.
Once active, the engine speed increased by holding the RES ACCEL button on the
steering wheel or decreased by holding the COAST button.
Stationary PTO is available only when the vehicle is stationary. When the truck is
equipped with an automatic transmission, it must be in Park and the service brake must
be released and functional. When the truck is equipped with a manual transmission, the
Parking Brake must be Set and the service brake must be released and functional.
To operate the PTO in this mode the vehicle must meet the following conditions:
• Be in "park" position ( vehicles equipped with automatic transmission)
• Upfitter provider (on/off) switch has been activated
• Parking brake applied (vehicles equipped with manual transmission)
• Clutch not depressed (clutch interlock switch)
• Vehicle must be running
• No transmission, engine, accelerator, 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. The vehicle is now in the PTO mode and is ready for use. In order to
