Re: ABS lights come on
Have you checked your brake fluid? If your brake fluid is low, you will need new brakes, or if you have a leak, you will need to inspect for it. As far as the sensors go, if your brakes and fluid check out, you usually need to get someone to read the code with a scanner. I believe they do it for free at Advance auto. Good luck.

U073 is a communication code from one module to another to simply put it. Code U073 refers to a communication problem with the electronic brake control module ( Which controls ABS/Traction and stability ). I would suspect a loose connection/shorted wiring or even possible internal problem with the brake control module.If the issue occurs after hitting a bump, most likely a loose connection or the wiring rubbing somewhere causing a short from the brake control module.
Sounds like you have a speed sensor signal dropping out. This would cause the ABS system to falsely think one of the wheels has locked up and would turn on the abs to unlock the wheel.
You can visually check the wiring harnesses to the speed sensors to see if there are any corroded connections, corroded wires or broken wires. If everything looks good than the next step would be to drive it with a scan tool and watch ABS data. You should be able to spot the speed sensors that drops out on the scan tool when the problem occurs. Than you can focus on that wheel to see what the problem is.
yes, you have an intermittent problem with the system and if you are in a situation where you need to apply the brakes hard, the problem may cause failure of the anti-lock brake system, not a good thing. The system may have stored a code indicating where to start looking for the problem. Unfortunately you would need a scan tool to pull the codes.
