Kia Troubleshooting Questions? Ask a Mechanic
?does your code reader have abs functions? what brand and model scan tool?
so it has no abs functions?
then it will not pull codes for the esc...thats electronic stability control and the codes are in the ABS module...you will need a beter scan tool
usually a wheel speed sensor can you access or borrow a better scan tool that can do whats needed to retrieve trouble codes? if not we can guess but thats not smart or cost effective
if you get me the code i can walk you thru troubleshooting
