Throttle Body needs cleaned up. IT gets a lot of carbon build up and replace the Idle Air Control (IAC) Valve .Trac light ???? check tranny fluid clean off wheel sensors, may help
check for broken wires to wheel bearing, if not it check bearing with ohm meter,change bearing or bearings and trac light and abs light will go out. if you can get your abs scanned with a scan tool it will save a ton of time and work.
