Circuit Operation

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 Controller Anti Lock Brake (CAB) is done on the following circuits. All of these circuits are a twisted pair.
B8 and B9 for the left front wheel (cavity 8 and cavity 9).
B6 and B7 for the right front wheel (cavity 6 and cavity 7).
B3 and B4 for the left rear wheel (cavity 3 and cavity 4).
B1 and B2 for the right rear wheel (cavity 1 and cavity 2).
