ABS Inop, TCS off, Brake light all come on at once

The ABS inop, TCS, Brake light all come on after driving for about 5 minutes and stay on. I think my rear end might be going out, any ideas?

Have someone with a scanner read the codes out of the electronic brake control module. The warning lights are indicating a problem with the system. Once you have the code you can start troubleshooting from there.

Mine did that when I first got the car. But since I replaced the battery, it hasn't done it since and it's been several months... ?

what kind/year of car is it? maybe someone knows how to get the ebcm to flash the codes. also, try unplugging and replugging in all of your speed sensors a few times. may just be a little corrosion on a terminal or something.
