Codes won't reset
 

I have tried every key, trip reset button including battery disconnect overnight to reset my PCM It is a Stock 2004 RAM2500 5.9L Cummins, I cannot get the check engine light off and clear codes for everything I have fixed. I used to be able to clear them last year. Anyone else run into the issue or have a solution.

Go to your local parts store, use one of their scanners to clear the codes.

Permanent codes cannot be erased until the issue is corrected.

What are your DTC codes?

P0541, p0532, & P2607 my grid heater was removed with the relays not needed in Phoenix Arizona plus I have a block heater for cold country. I just evacuated and recharged the AC system so all this has been corrected. I've been looking for a tuner (used) online but all I see are guys trying to sell ones that are locked to the vim without a clue that the unit does this. They must be stolen by what i can figure out. one guy said the smarty jr was in the cabinet at work for a few years and just wanted to get rid of it. I won't buy a used one till i know they reset their vehicle to profile zero and the unit is unlocked. I actually drove to one guy locally plugged it in and it was locked to another vehicle.
