This video explains how I diagnosed that I needed to replace the Anti-Lock Brake System (ABS) control module in my 2011 Jeep Wrangler JKU. It shows how I not only had the ABS and Traction Control instrument panel lights but also the red BRAKE light. Getting just the ABS and Traction Control lights is common when you have a wheel speed sensor fault. The BRAKE light isn’t common and, ultimately, pointed me to the ABS control module.

The video then shows some overviews of how you replace the control module. It’s a pretty easy task to do yourself and save some money over the dealership. The part is cheaper than from the dealer and you don’t need to pay dealer labor. You’ll still need to go to the dealer so they can flash/update the new control module to match your Jeep since they are VIN-matched. Total cost at the dealer for the flash was $165 in a May 2020.
When you get your part, contact the parts supplier and make sure you get the proper part for your VIN.

The part that I needed was part number 68089120AB, “Anti-Lock Brake System Module.”

Part 68089121AB, “Anti-Lock Brake System Module,’ will ALSO work in my 2011 JKU but would not work for my VIN. Unhappily, the part I needed was about twice the cost of the other part.

I got my part from dodgeparts.com:
