On many outer constant velocity (CV) joints is a reluctor or tone ring.
As the windows or teeth pass by the wheel speed sensor (WSS) in the knuckle it creates or changes a signal that is interpreted by the ABS modulator as the speed of the wheel. If the ring is out of alignment on an outer CV joint, it can cause WSS codes and the ABS to deactivate. Andrew Markel discusses how to inspect the outer CV joint and attached tone ring.

How does the vehicle know when to release the brakes? You guessed it. Active ABS speed sensors. Sponsored by Standard.
Standard is proud to offer a complete line of more than 2,600 ABS speed sensors, gas, diesel, electric, or EV, import or domestic. Standard has you covered.
In the past decade or so, we've seen a number of new technologies in the automotive industry. One of these is Advanced Driver Assistance Systems, also known as ADAS. There are a number of systems which fall under the ADAS umbrella, so to speak. Including blindspot detection, lane keep assist, parallel parking assist, trailer backup assist, adaptive cruise control, and much, much more.

The only way to diagnose the sensor and circuit is with a scan tool or scope.Â
ABS is the foundation of the ESC system. ESC systems add software and multiple sensors to keep the vehicle under control.
The process of finding and diagnosing real-world challenges can be more educational than expected.
Too small of a gap can lead to a weak spark and too large a gap can lead to misfires. Sponsored by Autolite.
