help with multiple codes on 1999 C5
I looked at a car in interested in buying and when I ran the codes using the onboard diagnostics method this is what I got:
PCM no codes, HVAC, no codes but......these were all historical codes:
AO-LDCM b2202, b2206, b2282, b2284, u1255, u1064, u1016, u1096
A1-RDCM b2283, b2285, b1255, b1064, b1016, b1096
BO-RFA u1096, u1064, u1016
HO-LDCM u1255, u1064, u1016, u1096
Is this cause for concern? The car only has 45k miles. Thank you!

Some may come back “key ON”…or come on while driving…scan before you shut the car off and any DTC’s will come back as “C” or current..other than looking at DTC’s I’d be doing a good visual inspection…a compression test would also be a good idea…if you can find a shop with a labscope they can do a “relative compression” test which takes 2 minutes vs using an “old school” compression gauge which takes 2 hours…you don’t even have to open the hood to do a relative compression test…your DTC’s are for the left and right door control modules and the RFA module which concerns the FOB and TPMS system…those U codes can caused by low battery voltage.
