OBD Code Help

Is there a list of OBD codes for 2004 H1?
In particular I'd like description of Code B2AAA.
H1 runs fine, though occasionally will not shift into high gear.

Thanks, ronlock

Re: OBD Code Help

An 04 is going to be tough, the proprietary CAT computer is a one of ECM. I'd recommend calling Lynch HUMMER with the code and ask them what it means.
