The 90 that I had did the same thing and my buddy that works for the local GM dealer told me to unplug the ABS plug next to the master cylinder for about a minute and it will reset as earlier stated and it worked. Checked the brakes and they were all fine. He said sometimes if you smash the brakes real hard it will do it or if you wheeling and are on the the brake s alot it will also do it.
