Codes for a 99 C5 ?
I finally checked for codes and here is what I came up with. C1226H, U1160H, U1064H, U1096H, 1064H, U1016H, C2105H, and C2115H. I'm going from memory but does the H after each one stand for historic ? I don't remember ever clearing codes in the 17 years I've owned the car. I went a head and cleared everything out just wondering what each code was. I did a search before posting this but nothing came up. Anyone have a list of codes ? Thanks !

Your 1226 code is from RF wheel excessive speed variation. Could be a variety of things, the sensor, bad or loose connection, etc. If it doesn't come back, no worries. The 1160 code was a loss of communication with your LDCM. If you've done some work on the door in the past that could have caused it. If everything seems to be working on the drivers door, no worries. The other Uxxxx codes appear because of other things/codes. OK to clear those. The last two, the 2105 and 2115 codes are tire pressure monitor errors for the RF and LR tires. Might need to replace those if you haven't ever done so. They only last for so long. But they can also be intermittent as well. If they're not showing up anymore, then don't worry about until they do. All in all, for not clearing your codes for 17 years, that is an amazingly small amount of codes. And none of them appear to be anything major.
