The ABS uses four variable-reluctance sensors to determine vehicle speed. The anti-lock brake sensors operate on the magnetic induction principle. As the teeth on the anti-lock brake sensor indicator rotate past the stationary sensor, a signal proportional to the speed of the rotation is generated and sent to the anti-lock brake control module through a twisted cable and shield wiring harness.
