Circuit Operation
- A toothed ABS rotor generates a voltage pulse as it moves across the pickup field of each ABS sensor.
- The amount of voltage generated at each wheel is determined by the clearance between the ABS rotor teeth and the ABS sensor, and by the speed of rotation.
- Sends alternating current signals at frequencies which are proportional to the rotation speeds of each wheel to the TCL/ASC electronic control unit (TCL/ASC-ECU).
- The ABS hydraulic unit modulates the amount of braking force individually applied to each wheel cylinder.
