Check the ABS wires that run to the front caliper - the clips come off & throw a code on my car every few thousand miles.

My 99 STS had the same problem, ABS and traction control lights on. The EBTCM (electric brake traction control module) is located left front under the hood below the air cleaner. The module has a ground peg coming from it that connects to a chassis ground. This connection corrodes! Clean it and make sure all is good, and all will be back to normal.

Bad sensor, my 1998 STS does the same, keep driving.
