abs and tc are abs related, most likely a bad hub. nothing radio related.
jack each wheel up, lugs tight, then grab the top of the tire, do a firm slow push and pull, if the wheel moves the hub is bad. you can also watch the rotor where it meets the pads and caliper look for the rotor to move, the caliper wont move.
if you can find any loose hubs or damaged wires to the hubs, take the car to be scanned. you could toss good money after bad hunting that down.
you'll need to get a abs code reader, or stop at a shop and have it scanned, they will charge you for this, but its better then tossing cash aimlessly at it.
