ABS INOP, Low Trac, ASR, and Brake?!?!?!?!

So, as I was driving home a couple of days ago all these lights came on. The ABS INOP and ASR stayed on most of the time and the Brake and Low Trac blinked on and off. I was told that the ABS sensor is the prime canidate for this problem. But, what is needed to do to fix this? I have no idea where the ABS sensor is. And I don't know how to fix it. The car was in storage this past winter, so there could very well be a problem with the wires or sensor. What should I do since I'm sure this is the problem? Thanks a lot.

Well my car is a little diferent since it's OBDI, but when my ABS inop light comes on and low trac light it means that a circuit in my car isn't getting energized. Those lights came on one day, and the whole accessory circuit was out-windows, radio, and the electric waterpump because it was tied in with that circuit. Are you having any problems with that stuff??

Nope, no other problems. Radio works fine and so do the windows.

The most common reason for those lights to come on simultaneously is low voltage. Clean connections as madwolf suggested and check your voltage.

Any other connects I should check other than the ground Madwolf pointed out? Also, where should I check the voltage? Thanks again.

I've had some similar problems. Try this, before you start the car, press the brake pedal down as far as you can and start the car. Mine use to do that and pressind won on the brake seems to get rid of it Dunno how, but it works

Anywhere you can access the power leads is adequate. Clean and tighten battery terminals and leads on the RH shock tower.
