ECM CALIBRATION

[catnred]

2016 Peterbilt 579 isx15 550 cummins, CM2350x101,
Check engine light on can't get rid of it!
Had 3 codes 1883,1845 and 5868 had them cleared on a generic lap with insite at a small shop! But light stayed on brought truck to our shop and found that it has no codes ,checked ESA and there are no codes in there either,was going to recalibrate the ecm but can't get any of our three laptops to do it, They all connect but won't calibrate,tried thru the cab and hooked direct to the engine, but keeps coming up with the same code and says calibration certification is bad cummins says its a Peterbilt problem.
One week ago we replaced the DPF filter[Recon],cleaned DOC,Replaced turbo actuator,In and Out Nox sensors,and cleaned everything up.the codes 1883,1845,adn 5868 were the same codes I got just before the work was done!
Maybe something happened at the small shop when they hooked up the generic insight?
injectors,good,maintenance free CV filter,everything seems to be good and clean!
Any Thoughts?
