Default Unusual column lock problem

I've read the Column lock thread, and I've watched a dozen YOUTUBE videos on the C5 column lock Saga. My issue seems to be a little different.

Everytime I put the key in the ignition or start the car, I get the SERVICE COLUMN LOCK Message. Once I press RESET, it never comes back. My steering wheel never locks. My fuel never cuts off at 2mph. I only get the DIC message, which I can clear. I've tried using HPTuners to remove the column lock feature from the ECM, but it still gives me the SERVICE COLUMN LOCK message. I'm stumped. Is there a way to stop this message from appearing?

I know this is a hot issue with C5s, but please don't flame me. I haven't owned the car too long, and I don't know what mods or recalls the previous owners have done.

Do you have a Column Lock By-Pass installed? The preferred by-pass is the LMC-5.

When you see the message, have you ever read the DTCs using the internal DTC reading routine? What DTCs do you see?

I just opened up the passenger footwell to check. The car has an LMC-5 installed.
I've pulled DTC's by using HP Tuners. I've never seen a column lock DTC. I have not used the internal DTC reading routine. I'll google how to do that, and see if there is a COLUMN LOCK DTC.

Here are the codes I found:
B2282 12V POWER FEED #1 FAULT
B2283 12V POWER FEED #1 FAULT
B2284 12V POWER FEED #2 FAULT
B2285 12V POWER FEED #2 FAULT
B2252 KEY CYLINDER SWITCH FAULT
U1016 NORMAL SOFTWARE FUNCTION, HISTORY STATUS UPON IGNITION CYCLING
U1064 NORMAL SOFTWARE FUNCTION, HISTORY STATUS UPON IGNITION CYCLING

No SES light, no other errors. The car runs & drives 100% OK.
