It is not uncommon for the ABS module to fail on your Kia. One of the symptoms of the ABS module failing is the ESC (Electronic Stability Control) light turning on. The ABS module has ESC integrated in order to help you stabilize your car while cornering and avoid skidding during braking. Regardless of what you call this module be that ABS module, ABS pump, ESC control module, we will show you how to remove it on most Kia vehicles.
The pictures in this tutorial are from a 2016 Kia Optima but owners of other Kia models such as Forte, Forte5, Rio, Sorento, Soul, Sportage, Rondo, Sedona, Borrego will find these DIY instructions helpful.
If you are certain your ABS module / ESC Control Module has failed you can use an ABS Module Repair Service to fix your existing unit. ABS module repair service cost around $100 USD, which is much cheaper than installing a new ABS or even a used ABS module.
