Default C5 2002 check engine light on
After not starting my 2002 for a couple of weeks,the car was dead so I plugged in the battery tender for a few hours ,than unplugged and started her up.I now have the check engine llight on and pulled all the codes from DIC but they are all history codes.How can I figure out if one of these history codes is the problem or could it be from the drained battery.These are the codes:BO432H BO502H B0503H BO507H BO508H B2482H B2483H B2587H B2592H B2282H B2284H B2262H B2283H B2285H U1064H BO851H U1255H. Thanks

Reset the codes, they are all history.

That will clear out the history of past codes as I understand it, but won't shut the check engine light?

Went to clear codes but started it up first for the heck of it and no check engine light and went for a nice drive,turned it on and of a couple of times and it stayed off. I guess I'll just keep an eye on it

Those are most likely low system voltage related dtc's from when the car wouldn't start initially.
