These type codes are quite often false triggered--often will set when going over railroad tracks or on a bumpy road---if the car seems to act and drive fine--i would just clear them and see if they come back---
The reason for the false trigger is the wheel speed sensors (which are used by the TCS system) will break contact or they will lose ground----
Even if the codes come back--check all 4 of the wheel sensors--make sure the pigtails are clean and the wires are not frayed-make sure there is no debris in the sensor area by the rotor --rarely do the sensors themselves need replacing--
