So on the Powertrain faults immediately after (or in fact during) updates. Yeah that happens sometimes and is caused by an interruption of communications between modules and the individual networks each module is on.
I had a discussion with my local senior tech yesterday concerning this very issue and he pointed out that the DTCs that start with a "U" relate to communications errors that result in these errors showing up. If you do a key cycle and the error clears then it was probably bogus to begin with.
