Prostar Body Controller

[DVT873]

Post the complete VIN and I might be able to see your set up. Never tried on a CAT. DLB is it's own little world. A slow blink usually means a requirement aka interlock has not been met. The DLB program can open all the details. Find the parameter, click on it then click on "make session". That will show you all subparameters and signals involved.

Is the PTO an air shift? If it is find the trigger air line. It will likely go back to an air solenoid pack on the frame. That solenoid is what DL is controlling. You can bypass it with any air solenoid, a fan clutch solenoid will work fine. You can control it with a toggle switch.

All DL does is allow interlocks and conditions to be programmed in. Example, maybe you want the PTO to disengage obove 32kph. Or Maybe the suspension has to be dumped, or the brake set, or the passenger door has to be open. Whatever crazy shi#t somebody thought was a good idea. But after all those hoops are jumped thru it still comes down to that frame solenoid getting triggered.

Horton makes an solenoid kit that can set up to be Normally Open (NO) or Normally Closed (NC)

As far as the other issues you could have disturbed something when you "deleted the code which kept the headlights on all the time and a couple of other things." If all your problems started after that then it likey one of the "other things" you changed is tied in.

The good news is that since you are using a "cracked" version of DLB your changes did not get wriiten to the master file in the NAV cloud. Have never tried on a CAT truck but from what I know about Blue Diamond, and some rebadged Perkins and DD engines NAV has the master file.
