Cummins engines support REPTO, FEPTO, Split Shaft PTO, as well as 6 bolt and 8 bolt PTO devices. Note that specific support may be dependent on the engine model, rating, truck model and the selected driveline

Typical Applications (not all inclusive)

REPTO/FEPTO – Refuse Trucks, Cement Mixers, Cranes, and Sewer Cleaners
Split Shaft PTO – Emergency Vehicles, Hydro Excavators, Sewer Cleaners, Concrete Pumpers, Oil and Gas Service Rigs, and Drilling Rigs
6/8 Bolt – Paint Stripers, Fuel Tankers, Propane Tankers, Water Tankers, Roll Offs, and Dump Trucks

Currently supported engine control interfaces

Standard Cab PTO control – Use of the OEM provided Cab Cruise/PTO switches to control engine speed
Remote Station PTO control – Uses direct wiring of PTO On/Off and Set/Resume back to the Cummins ECM. This method allows the cab PTO switches to remain multiplexed through the truck
Remote PTO control – Uses direct wiring or multiplexing of one switch to set engine speed to one of five preset engine speeds
Remote Accelerator – Uses a potentiometer setup (hardwired or multiplexed) to select a desire engine speed
TSC1 Control – Utilizes SAE J1939 PGN 0 (TSC1) in order to operate the engine at a particular speed or torque or to enforce a speed or torque limit
Transmission Driven PTO – For Split Shaft PTO rigs allows the selection of custom governor tuning for a particular application. Also disables speedometer while in split shaft mode.
Fire Pressure Governor – For emergency vehicles

Body Builder FAQ

Which vehicle datalink circuit should I connect to in order to send commands to the engine?

If the diagnostic connector is Gray and has 6 pins please fill out the form at the Contact Us link below.

If the diagnostic connector is Black and has 9 pins use the primary SAE J1939 vehicle datalink which is connected to Pins C & D in the diagnostic connector If the diagnostic connector is Green and has 9 pins it depends on the OEM and model.

Navistar – 500 K Baud datalink on Pins C & D
Volvo/Mack – 250 K Baud datalink on Pins H & J
Autocar – 500 K Baud datalink on Pins C & D
Kenworth/Peterbilt – Legacy Chassis (ie KW T800, Pete 367 – 250 K Baud VCAN datalink which is found on Pins F & G
Kenworth/Peterbilt – New Generation Chassis (ie KW T880, Pete 567 – 500 K Baud VCAN2 datalink on Pins C & D
All other OEMs – Most others use 500 K Baud on Pins C & D. If not sure click on the Contact Us link below.

Are engine torque ratings speed dependent?

Yes – Maximum available torque varies by engine model and rating. Please click on the link for Heavy Duty Truck or Medium Duty Truck to find details on various Cummins engines. Available torque and power by speed is listed along with Clutch Engagement Torque (That is torque available at idle speed).

Does Cummins support hardwired and/or multiplexed PTO switches?

Cummins supports multiplexed Cab PTO and Remote PTO switches. Cummins supports hardwired Cab PTO, Remote Station PTO and Remote PTO switches. Remote Station PTO has the same functionality as Cab PTO switches but allows for hardwired switches from a “Remote Station” while also allowing the Cab PTO switches to be multiplexed. Remote PTO can also be multiplexed. If you wish to send Multiplexed Cab PTO switches from a remote source that is possible by changing the source address under SAE J1939 Multiplexing for PTO On/Off and PTO Set Resume to the source address of your device.

Does Cummins support multiplexed and/or Remote Accelerators?

Cummins supports both. An enable switch must be provided along with the Accelerator device itself.

Does Cummins engines support J1939 TSC1 control?

All Cummins on highway engines support J1939 TSC1 control for Engine Speed Request, Torque Request, Torque Limit and Engine Speed Limit.
