Here is the deal. After replacing the rear brake pads and bleeding the brakes on the 850, I had a firm pedal with the car not running, so I started the car to try it. Pedal still nice and firm, but now the ABS and the TRACS light were on. I didn't mess with any connections, so it stumped me. I rechecked everything, and even made sure the fliud level was ok, which it was, but still had both lights on the dashoard lit up. Tried toggling the TRACS switch too, but it made no difference.

So, I turned the car off, waited a couple minutes and re-started it. Result.....no lights, and firm brake pedal. Road tested ok. Re-started 2 more times and no lights. Any idea what could have caused it or if I should worry about it??

Wait to see if it comes back on.
Sometimes they will act like this. The ABS finishes its test when you hit 15MPH.
