Hello and welcome to JustAnswer!

These warning lights have come on because the engine controller and ABS module have seen a failure in a monitored component and set a fault code. There are literally dozens of things that will turn these lights on, if they started coming on together then the traction control light is most likely on because of an engine performance concern such as an electric throttle control issue.

The first step in diagnosing the problem is to use a scan tool or code reader to see what fault codes are setting in the PCM and ABS module, and then testing can be done from there.
