I changed my diff fluid (including the required LSD additive) and ATF fluid/filter last weekend. All of a sudden, I have been getting random Service Traction Control/ABS messages. Is this a coincidence, or is there something that I did (or didn't) do to it during maintenance that could cause this?

Got them, however, I turned off the car before realizing it. I immediately turned it back on and still had the warning light, but I'll double check after the next time I drive it to make sure there aren't any other current codes.

The current codes:

C 1291 HC: Open Brake Lamp Circuit During Deceleration - I have LED Halo tail lights, but I have never received this code until a couple of days ago.

B 2860 HC: Telescoping Column Position Sensor Failure

C 2110 HC: Right Rear TPM Sensor Malfunction - battery is dead

The HISTORICAL codes:

C1221/1222: LF/RF Wheel Speed Sensor Input Signal is 0 - When I had up on jack stands I put it in Drive to circulate the new tranny fluid.

B1001H: Option Configuration Error

B0338H: Inside Air Temp Sensor Open - fixed

B2282, 2284: 12V Power Feed #1 Fault LDCM @B2284 12V Power Feed #2 Fault - probably occurred during stereo install or b/c of dead battery

B2264: Mirror Vertical Position Sensor Fault

U1064: Normal software function, history status upon ignition cycling

B2253: Key Cylinder Switch Fault

B2283, 2285: 12V Power Feed #1 Fault, 12V Power Feed #2 Fault

B2263, 2265: Mirror Horizontal, Vertical Position Sensor Fault

B2857: Telescoping Column Out Switch Shorted to Ground

B0851: Battery 1 Out of Range

B0856: 5 Volt Reference Out of Range

U1300: Low voltage on the class 2 serial data circuit.

U1255: Lost Communication with XXX

U1096: Normal software function, history status upon ignition cycling

U1016: Normal software function, history status upon ignition cycling

*C2100: Left Front TPM Sensor Malfunction - Works just fine; probably lost communication with it when wheel was removed to have a hole patched.

C2105: Right Front TPM Sensor Malfunction

C2110: Right Rear TPM Sensor Malfunction

C2115: Left Rear TPM Sensor Malfunction

I don't have a service manual to look up troubleshooting procedures. Any help would be appreciated.

After doing some research, it appears that I may have a faulty brake switch - I could need cleaning and/or adjustment, or a bad wire connection somewhere. That does explain the randomness of the occurrence, however I know for a fact that it came on tonight while I was accelerating, so I call BS on this trouble code!

The only two codes that are sticking after clearing everything is 1291 and the telescoping steering wheel.

Unfortunately, I have no brake lights now. Any workaround for this until I have time to work on the switch?

Good news and bad news.

Good news is that it was just a blown fuse.

Bad news is I need to figure out why it blew.

At least I can drive it now. I know that the warning light first came on when I hit a sharp bump.
