a bad wheel hub assembly will set off the abs / TC lights. the wheel speed sensors are built into the hub assembly . could also be just the wire harness that connects into the speed sensor. go to autozone or advanced auto and get them to pull the codes for you . then try unplugging them and cleaning the connectors with electronic cleaner. if that doesn't help check the resistance at the wire harness with a multimeter and if they aren't reading close to the same then you know it's in the harness. if they give a good reading then it's the speed sensor itself and you'll have to replace the hub assembly. here's a helpful video showing you how. CHECK YOUR BRAKE FLUID. make sure it's at the proper level .
if a scan tool won't pull the codes then you're probably looking at a bad ECBM.
