When did they come on? While you were driving? When you first started the car? If so, what was the car doing in the hour or two before you started it? Just sitting there? Were you doing something to the car? sitting in it? pressing the brake pedal repeatedly?

They all have one thing in common.... road speed. Like the other member said, traction control. A wheel speed sensor (or ring) may be bad. Most likely cause is the DSC module, iv seen these take a dump around 02. There are other causes too but those i mention is most prob cause.

Start right here... I had all these faults, cleaned the wheel speed sensor and they all stopped...

Clean them, check their connections and see if your errors go away.
Mine did the same thing... after a burnout... they randomly went away. Then came back, then went away when I got all my tires changed. So yeah, hopefully they won't come back. :facepalm:

So just had this happen to my car driving it this morning. Roads were moist and it was roughly 33 degrees out. When I shift gears (SMG) the 4 lights mentioned would flash and go away. After i dropped my son off, and turned off the car and restarted it, it did not do it on way home.

Check brake fluid level? Make sure the switch works, when the cap is removed the float drops, turning on the switch, which should light up the low brake fluid icon.
