6 and 8-Bolt PTOs
Overview (Continued)
Mobile Mode
To operate the PTO in this mode the vehicle must meet the following conditions:
■ Dealer selected mobile mode activated via Dealer proprietary service tool
■ Up fitter provided (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 before putting the vehicle in gear and moving. 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 or reverse gear
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. Since this is a torque converter driven gear in
the transmission, PTO function will not occur until the wheels start moving at a rate of approximately
5-7 mph.
NOTE: For application specific information with respect to PTO and pump requirements and additional
vehicle information (wiring schematics, preset idle values, engine speed limits, and vehicle hardware and
software requirements) please refer to the Dodge Body Builders Guide by accessing “Wiring
Diagrams” and choosing the appropriate links.
