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

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 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.
Mobile Mode
This feature is activated by a switch (close to ground) in the cab after selected by a
service tool. When active, this feature limits engine speed and
road speed to calibrated
values.

When this feature is selected stationary PTO and Remote PTO features
(the idle increase
features in PTO mode) are not available.
To operate the PTO in this mode the vehicle must meet the following conditions:
•Dealer selected “mobile” mode activated via Dealer proprietary service tool
•Upfitter provider (on/off) switch has been activated
•Vehicle must be in “park
” or “drive” position (vehicles equipped with automatic
transmission)
•Parking brake must not be applied
•No vehicle, brake or clutch switch faults present
•Vehicle must be running
•PTO must be correctly installed using the vehicle provided circuits
The customer may choose to use the PTO while the vehicle is moving. To do so the PTO
function must be activated prior to taking the vehicle out of “park”. This is accomplished
by activating the up fitter provided PTO on/off switch. At this point the customer may
place the vehicle in a forward
, reverse gear, or neutral and have PTO operation.
To disengage PTO operation and return to “standard vehicle operation” simply turn the
up fitter provided on/off switch to the off position.

Remote Stationary mode
This feature interacts with the transmission to utilize an auxiliary shaft to drive
equipment. Activated by a switch outside of the cab, this feature operates only when the
vehicle is stationary. The input is switched to ground.
Once active, the engine speed is changed when the switch changes from Off (open
circuit) to On (closed to ground) or toggled in less than ½ second. Toggling the switch
On-Off-On triggers the engine to change to the next calibrated engine speed. This can be
repeated for up to five engine speed settings. Repeated toggles cycles through the engine
speed 1-2-3-4-5-1-2 and so on.
Remote PTO can be calibrated for one to five selectable engine speeds. The engine
speeds are also calibrated.
Remote PTO feature has a higher priority than Idle Up. If the Remote PTO feature is
active the Idle Up switches are ineffective. The Idle Up or Stationary PTO feature cannot
be activated until the Remote PTO relinquishes control
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
Various features provided by the Cummins module
Single Set Speed ( sub set of remote PTO)
Single set speed allows the customer to set up the PTO to operate at a single idle speed.
This speed is “remembered” through ignition cycles or battery disconnect. The set poin
t
can be changed unlimited times and in increments of 25 rpm’s. These are the instructions
to learn and unlearn Single Set Speed:

LEARNING SET SPEED
NOTE: This Feature Requires Engine Calibration Software released in December
2008:
If your vehicle was produced before December 2008, you must have the dealer “Reflash”
the engine controller to December 2008 or later engine software.
In order for this feature to work the PTO MUST be wired as REMOTE PTO (pto
switch between F425 and V937) not standard PTO.
¾Key ON (Engine not running)
¾Press and release Cruise SET button 5 times within 10 seconds
¾Start Engine (Engine Running)
¾Go into IDLEUP Mode (Cruise ON then SET to go to 900 RPM)
¾Set the desired speed (using cruise switches)
¾Press Cancel
¾Turn key off (to save the setting)
UNLEARNING SET SPEED
¾Key ON (Engine not run)
¾Press and release Cruise Set button 5 times within 10 seconds.
Note: To LEARN a new speed, first UNLEARN the old speed
¾Once the idle speed is LEARNED, the engine will go to that idle speed whenever
the Remote PTO switch is turned on, without additional operator assistance.
¾PTO will engage first and then the idle speed will ramp up to the LEARNED
speed, thus not violating the AISIN requirement of not allowing PTO engagement
above 1000 RPM.
¾The LEARNED speed is saved at power down.

5 preset idle speeds (sub set of remote PTO)
This feature comes factory preset to the following 5 engine idle speeds 900, 1100, 1300,
1500, 1700 rpm’s. They are attained by successively toggling the PTO switch on and off,
by doing so the idle s
peeds will step through the preset speeds and will wrap back around
to the beginning set speed if the on/off switch is toggled enough times. These set speeds
can be changed to any speed between 900 and 2000 rpm’s using a dealer service tool.
This will give
the customer the ability to have multiple idle speeds to operate his/her
equipment.
Remote Throttle and Remote Throttle Switch
This feature allows the user of a continuously variable throttle. This throttle
potentiometer is power by the 5 volt supply and sensor return lines provided.
This feature is activated when the Remote Throttle Switch is On (closed to ground) and
the main throttle is closed. Remote Throttle does not require idle validation switches and
is not to be used for main vehicle accelerator.
Accelerator interlock
This allows the accelerator to be locked out when activated. This feature is often used in
