WTH...spurious codes?
I had my back end up on ramps this morning and when I started my engine to drive down off the ramps I got two error messages flash across my DIC..."Traction Control System Error" and "Reduced Power" or something similar and the check engine light stayed on. So I drove the car to breakfast and when I started it up again the check engine light stayed off....I then checked the codes and I had the following codes:
P1518H PCM to TAC Serial Data Circuit
C1278H TCS temporarily Inhibited by PCM
B0367H Right Actuator Feedback Open
So it seems to have been a spurious error, but what's up with that?
Has anyone seen this before or have any idea what might have happened?

At this point I would just clear them and assume nothing is wrong. I have had several of these episodes, spaced over time, but never any real problems. The one thing I would watch for is a low battery. This will first show up with your DIC always defaulting back to the odometer and the HUD defaulting back to factory settings.
