Overview (MY2013 & Later) (Continued)
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 provided (on/off) switch has been activated
• Parking brake applied if feature is enabled (vehicles equipped with manual transmission)
• Clutch not depressed (clutch interlock switch, vehicles equipped with manual transmission,
MY2013 thru MY2018)
• Vehicle must be running
• No transmission, engine, accelerator, brake or clutch (manual transmission) switch faults present
• PTO must be correctly installed using the vehicle provided circuits
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/software
requirements) please refer to the current RAM Body Builder’s Guide PTO Operation & Installation Guide.
