Suddenly multiple codes: What's up?

[ZO6_Bryan]

My check engine light came on tonight and when I went to scan it I found multiple codes stored. I'm sure the O2 sensor code is probably what turned on the light. But what are all these other codes. This is an 02 Z06 with cam and headers, never thrown codes before. When I try to erase them the O2 code is gone but all these others stay. Anyone have a clue whats up?

This is the list of codes saved

[PCM] P0133 - HO2S Slow Response Bank 1 Sensor 1 (SES) (Old) (History) (Current) (Immature)
[Convenience] B2282 - Unknown (History) (Immature)
[Restraints] U1000 - Class 2 Communication Malfunction (History) (Immature)
[Entertainment] U1064 - Loss of Communications with DIM (History) (Immature)
[Convenience] B2284 - Unknown (History) (Immature)
[Convenience] B2283 - Unknown (History) (Immature)

Yeah, just fix the P0133 code, probably a bad O2 sensor. The B & U codes always appear when scanning for some reason on my car, as well as customer vehicles, even though there are no problems.

Well, I just got them to clear using the instrument panel on the Vette. HPTuners wouldn't clear them. I think they may have been set when my battery ran down.

Most of the U-codes get set when you program the PCM. Just other modules wanting to talk on the buss when programming is going on so they "throw a fit" and set codes.
