C5 Error Codes
We have a 1999 C5 with 100,500 miles on it. It is rarely driven anymore. Last November we replaced the battery and unbeknownst to us, the dealership sold us a battery for a different car. We started noticing issues on the dash the few times that we drove it. We just replaced the battery a few days ago and that's when it was discovered that the dealership had sold us the wrong one before. Now with the correct new AC Delco battery in, we checked the codes. This is what we came up with:
58-SDM B0051HC and B1000H. A1-RDCM B2283H, B2285H, B2265H, U1255H, U1064H, U1016H and U1096H. We were able to clear the other codes that came up but these remain.
Also noticed that the odometer now reads about 65K miles more which is definitely wrong.
The driver window no longer works at all.
The alarm chirps like crazy when the keypad is within about 25 feet.
I have searched and cannot find these codes as we read them.
Can anyone help?
Thanks in advance.

Seems like all of these issues are BODY CONTROL MODULE related An engine code or drivetrain code is always a "P" code
B codes are for the BCM
U codes are normally communication codes which can be a result of a faulty BCM --Bad ground --- failed wiring--or a bad column lock or ignition swith
Do you have another key? If so try using it as these keys wear out---Have you tried dis connecting the battery for 24 hrs ? if not try this as well as it will unload any "glitches" in your ECM or BCM
