Here is what I have for two of the codes

P<?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com[img] /><st1:NumConv6p0 sch=[/img]0278</st1:NumConv6p0> Cylinder <st1:NumConv6p0 sch="1" val="6">6</st1:NumConv6p0> Contribution/Balance Fault<O</O

P<st1:NumConv6p0 sch="1" val="0603">0603</st1:NumConv6p0> Internal Control Module KAM Error<O</O

P0405 - don't know.

I'm sure someone else will be along w/ more info.

The P0278 is contribution balance error #6 cylinder. could be an injector.
P0405 is an EGR gas recirculation sensor A circuit low. voltage below a specified range.

If the truck is running fine you may have some left over codes from before the repair. The tech may not have cleared the codes when he was done. I would clear the codes give it a few days and check again.
