Overview (MY2013 & Later) (Continued)
Mobile Mode
Mobile mode allows for use of the PTO when the vehicle is in motion. This feature, when activated by the menu
available on the Electronic Vehicle Information Center (EVIC) screen in the center of the cluster, will allow you to
enter mobile PTO mode when you press the PTO switch on the dash. When this feature is selected stationary
PTO and Remote PTO features are not available.
To operate the PTO in this mode the vehicle must meet the following conditions:
• PTO switch has been activated
• Vehicle must be in park position (vehicles equipped with automatic transmission)
• Parking brake must not be applied
• Clutch not depressed (clutch interlock switch, vehicles equipped with manual transmission,
MY2013 thru MY2018)
• No transmission, engine, accelerator, 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 PTO on/off switch. At this
point the customer may place the vehicle in a forward or reverse gear and have PTO operation.
The PTO will also function in park and neutral but without an increase in idle speed. However, the accelerator
pedal can be used to increase PTO speed. Mobile mode does not provide the exact same capability as a ‘live
drive’ i.e. you cannot have PTO capability at zero vehicle speed in drive. However, some customers have had
success with shifting the vehicle into neutral and allowing the vehicle to coast.
To disengage PTO operation and return to standard vehicle operation simply turn the up fitter provided on/off
switch to the off position.
Remote Mode Features
Remote mode allows the use of an aftermarket auxiliary switch to actuate the PTO. Presumably this will be from a
location other than the cab of the truck, or some automated/relay driven method to turn on the PTO is required.
Remote PTO can be calibrated for one to three selectable engine speeds.
Remote mode also is the only method that accommodates multiple PTO speeds. Up to three different PTO speeds
can be programmed. These speeds are programmed via the Electronic Vehicle Information Center (EVIC) screen
in the center of the cluster. The circuits that enable these multiple speeds are contained in the Vehicle System
Interface Module (VSIM). The VSIM module is located under the dash on the driver’s side. The connecting wires
are contained in the upfitter wiring kit and VSIM wiring kit.
