[QUOTE="bringbackscab, post: 1696470, member: 37665"] Hello all hopefully someone has had a similar issue. I have a 2017 supercab, I just installed a new battery ~ 1 week ago with ~ 250 miles put on (battery put on maintainer first day). About a month ago I had the cam phasers 21n03 and the pcm reprogram 21n08 completed on my truck by dealer. I had my truck on a 4 amp charger "in case" during ecu/tcm flash but the battery level never dipped below 75%. Everything went fine. Upon starting, I get the dreaded check engine light, and a notification to my fordpass of "malfunction indicator lamp; the powertrain control module has detected an internal memory problem". Truck runs ok, I contacted Ty at cobb and he is checking out the diagnostics because the accessport is not detecting any codes despite the code being on the truck. Has anyone else experienced this yet? I'm still a noob but at least I try and follow directions well :-) I tried doing a forum search but it doesn't appear this has been covered, if it has, my apologies. Thanks [/QUOTE]
