Jake brake 2011 prostar

I would rather he stay out of a truck all together

 

The engine brake controls on a Prostar are computer controlled. The buttons on the steering wheel and level switch in the dash are a digital inputs to the body controller. The body controller communicates to the ECM that the driver is requesting engine brakes. If the body controller is getting a valid command from the switch on the steering wheel, the indicator light should light up in the cluster. There are no relays or fuses. There is just the steering wheel switch, then the clock spring, then just wiring down the column to the body controller which is next to the clutch pedal behind the left most kick panel. Buttons do fail. Clock springs are pretty good actually. The biggest problem is the steering wheel column wire harness is rubbing through on the steer column support brackets. This usually involves more than one wire and you will experience weird cruise control and/or wiper operation too.

 

Hi guys, in my 2010 Prostar/Cummins ISX, the Engine brake, Suspension dump, PDL lock, DPF system and Seatbelt light all quit working altogether. What do they have in common?
P.S: It happened temporally yesterday (for about an hour), then when they came back on, the Seatbelt light and all DPF lights, came on (while driving), they stayed on for about 3 minutes and turned off, because I had my seatbelt on and DPF system wasn't running Regen at the time. Today it happened again, but permanently unfortunately.

 

What fuse number was your engine break on the prostar
