2004 Dodge Ram throwing codes

[Dtibbetts12]

Bought a new t2 and now I’m having CEL light issues with any tune I use. CEL light is flashing on and off at random for codes P0585, P0593, and P0581 all cruise control codes (an option my truck doesn’t have) anyone have an idea how to go about correcting this?

This is not something I have ever seen before.
Did you adjust tire size or any other settings?
Do the issues go away when you go back to stock?


Thanks

Stock tire size, no other changes to settings. I’ve tried the 87 time, MPG boost tune, and tow tune. I have not attempted to put it back to stock. I can try that tonight when I get home.

Set the truck back to stock tonight and took it for a ride, it went back to normal. No CEL flash and it’s not setting any codes. I’m confused as to why the tune would pop a light for options the truck doesn’t have...

OK, give it a day or 2 stock and we'll make sire its ok, then load the tune again with no change.
If the issue comes back, please post the files from the tunes folder here so we can check it out.

pulled out my scan tool and scanned for codes while the truck was still stock, no codes after leaving the truck stock for a few days. put the truck back to 87 tune and scanned directly after and all 3 codes were back.

Just to confirm, when you load the tune are you adjusting the tire size by entering the stock value or not adjusting anything at all?

[Dtibbetts12]

Loading tune as is, not making any adjustments

[Dtibbetts12]

Any update? Today is the last day of the return period. If there is no resolution I’m going to set the truck back to stock and buy from another company, no sense wasting $600 on something that doesn’t work correctly.

I had a calibrator go through the tune as well and nothing stands out that could lead to these codes or issues.
I've never seen this on another 04 Ram at all.
I would understand if you choose to return, and I hope whatever you go with works out with no issues.


Thanks
