1) Does the programmer cause a PO603 code? last night I was driving and the truck died. After about 5 minues it started up and seemed fine. Loaded the original backup and seems ok but pulled PO603. any ideas?

2) I have never updated my programmer, I see there has been 2 updates. Can I just update to the most recent?

Thanks!
