Help! I fixed problems leading up to red exclamation light on Cummins ISX (Prostar).

I am a O/O, with a 2010 International Prostar ISX 435HP (Cummins engine). My DPF light was starting to come on, indicating the filter was getting clogged up. It eventually started to become more frequent, until finally it started coming on every 30 seconds or so. I attempted to drive from West Texas to South Texas to address the issue. However, right before I was done with the trip my red exclamation mark came on, followed by a relentless beeping. My engine lost power way before the red light come one (running sluggish).

I have run all the codes, and addressed all issues. DPF filter was taken off and cleaned; EGR cleaning was done and all sensors on engine and turbo replaced. That took off all DPF indicator warning lights. I changed all the filters and oil, which I believe to have been the major problem. There was indication that the previous PM one was not done correctly (filters were bad). That fixed the turbo boost gauge from going well above 30.

My gear ratios are back to normal (shifting my 13 speed is back on track). Truck turbo is not over working. DPF light non0-active (while conducting test runs). However, the red exclamation light is still on and beeping. The engine is still in its safe mode (loss of top speed).

I am broke after addressing issues and can't afford to sit or pay for dealer computer to remove red light. My question: Will the light turn off on it's own, or can I just manually override it myself?

After all, if there is still anything wrong with engine afterward, the truck computer will repeat the sequence leading up to the shut down indicator light.

 

10-4, I found a link for a Peterbilt with the same engine that indicated a specific sequence to shut down warning lights and return power to engine:

Turn truck off; start; push park break in and out twice; put truck in and out of any gear (same gear) twice; clutch in and out twice; hit the break twice. That resets all the warning lights and gives all the power back to the engine. I am going to see if that works on my Prostar.

Anyone with additional insight, please post.

 

I serviced and researched everything prior to doing so. The problem I am having is turning off the engine alarm after all corrective methods have been taken care of.
