CIRCUIT OPERATION
There are four wheel-speed sensors, one at each wheel. The sensors use a tone wheel to determine wheel speed. Input to the ABS controller is
done on the following circuits, each of which is a twisted pair: B8 and B9 for the left front wheel (cavity 11 and cavity 4) B6 and B7 for the right
front wheel (cavity 18 and cavity 3) B3 and B4 for the left rear wheel (cavity 2 and cavity 10) B1 and B2 for the right rear wheel (cavity 1 and
cavity 17).
