While the OBD2 Scanner(s) can make an Errant ABS Code Diagnosis, there is a much more Direct Method of approaching this problem by following along with what this VOP (Video Original Poster) does when using his Digital Multi-Meter to probe the ABS Sensor's 2 Pin Harness Connector.
The ABS Sensor functions by its 'near proximity' to the Rotating Internal Notched Reluctor Wheel inside of the Wheel Bearing Housing. With the Tip of the Plastic Covered Micro-Coil Transducer sticking down inside from the Base of the ABS Sensor, it is supposed to pick up
Fluctuations of Alternating Current that, if nominal... should read about
450 Milli-Volts on the DMM Screen when spinning the Wheel By Hand at Very Low RPM.
Anything less for the Milli-Volts Reading can indicate either a Bad ABS Sensor (not very likely) or the sad, but easily rectified condition of having a Thick Layer of Rust Scale Build Up swelling the Outer Cast Iron Axle Bearing Housing. This Junk can thicken bad enough to elevate the Base of the Plastic ABS Sensor Body and make it 'tall' enough to move that cylindrical coil well up and away from those Tiny Reluctor Wheel Teeth. The ABS Malfunction follows on whenever this occurs.
