TCS LED ON, DSC Blinking
A somewhat less-than-casual search here has turned up nothing useful.
My TCS and DSC lights are on continuously since the second day of my passed weekend track excursion.
Well, nearly continuously - They were not on for the second drive this afternoon to the gas station. Then they came back. The DSC light is blinking. The ABS light is off and the start-up sequence is normal.
The steering angle sensor is calibrated and I swapped my brakes back to my street setup and it made no difference. Fluids are OK and the wheel speed sensor harnesses and connectors look fine. No blown fuses.
I haven't "tested" the DSC/TCS/ABS, but I presume they are inoperative. Everything else about the car is totally normal and there are no weird noises or smells. A battery-pull did nothing and I'm not sure why the lights were off for the one, short drive. They are on right at start-up otherwise.
Anyone run into this before?
I'll probably have to go to the dealer to get the codes read since they aren't reported as a normal part of CAN/OBD.

Wheel wasn't off.
I usually do the 20-second button press before I go on track, but somewhere along the line (after a handful of sessions) it failed before I could even press the button.
The combined sensor is on my checklist for tomorrow. Thanks for the suggestion.
The button itself is on that list as well.

It's gonna be a "C" code.
Just repaired an RX8 with the C1293 code. DSC and TCS lights were both on.
Turned out to be a cut and shorted 3rd brake light power wire. That only took 3 hours and 7 fuses to figure out.
Code was due to the electrical short in the brake light circuit.
C1291 - Open Brake Lamp Switch Contacts During Deceleration
C1292 - Brake Fluid Pressure Sensor Circuit
C1293 - Code C1291 Set in Previous Ignition Cycle
C1294 - Brake Lamp Switch Circuit Always Active
C1295 - Brake Lamp Switch Circuit Open
C1296 - Brake Fluid Pressure Sensor Circuit
C1297 - PCM Indicated Brake Extended Travel Switch Failure

See anything I really should add to my list besides Easy's cut and shorted 3rd brake light power wire?
Zoom...............little more info on exactly where "combined sensor" and or connector is please?
Some reason I'm not getting what rear console means.

I have had am Issue similar when those lights come on at random if feels like a clutch slipping. This would happen when trying get up to 100mph. I check the connections rest and they would go away. I ran check codes and nothing comes up neither. So I scratch my head like wtf. With the lights coming ok the dash for no reason. This wouldnt happend all time just at random only.

Let me know..............I pulled that number from a couple of threads where people used the 150ohm and had success.
I just tried to condense all possibilities into one thread.
