Just a picture I got of google. It is called a reluctor ring because of the reactance it produces with it's ajoining inductive coil pick-up. Since a coil cannot produce a square wave it produces a spike at each edge of the toothed ring. One spike is positive and the other is negative. The circuit eliminates the negative spike and clips and amplifies the positive spike. This circuit counts the number of spikes per second therefore knowing the velocity of the wheel which it can compare to the three other wheels. Coming back to the thread topic when a bearing gets bad enough this reluctor ring misaligns itself with the pickup and no more pulses are produced. Circuit detects one wheel is stopped and three are turning and puts out an alarm. In this case it disables the ABS pump and turns on the ABS light.

U know krjrcustom1, that is my big problem with writing. It is hard to put in words ones tone of voice. Emoticons help express the tone better sometimes . I'm not easily upset. But I often misunderstand peoples intentions. Plus english being my second language sometimes I just plain don't understand.
