How do you enable PTO on prostar using cruise buttons?

Make sure brake is set and clutch pedal is up all the way. Turn cruise on. Now this is where it gets funny. I have also found the pto function to simply not work sometimes and it comes down to button pressing sequence. I found if I press and release the set/coast button, you will notice a slight flutter in the engine RPM, then press and hold the Resume/accel button and the rpms should increase. I don't know why, but many times if you press "on", and then press resume/accel it does nothing.

 

On Prostar if its activated in the ecm its

Turn curise on then hit the accel button once. rpms should spin up to 900. If its not activated nothing will happen.

 

This method is not pto, its idle adjust and a way you can make your truck always return to a set idle. The on + resume is the only way to put it into PTO and requires the feature to be activated on the truck.


Edit,
I would upload a video of the setting in insite and it activating but youtube wants to be stupid and wait on wifi instead of just uploading the #### video.

 

Be sure your shifter is in neutral. On Prostars the sensors are sometimes a bit wonky, and if you breathe on it wrong it will think the truck is in gear.

 

Maxxforce or Cummins engine?
