^ The anti-lock brake sensor electrically senses each tooth of the anti-lock sensor indicator as it passes through the anti-lock brake sensor's magnetic field.
^ This data is sent to the anti-lock brake control module. The anti-lock brake control module monitors the brake anti-lock sensors to determine wheel rotational speed.

^ The front brake anti-lock sensor indicator is part of the outboard CV joint.
^ The front brake anti-lock sensors are not adjustable.

^ The rear brake anti-lock sensor is bolted to the rear wheel spindle.
