OBD Code Help

[ronlock]

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

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.
