Scoping Wheel Bearings
Using an oscilloscope or scope can measure more than just the output of the signal. Testing with a scope can show the health of the circuit with the wheel speed sensor on one end and the module at the other.

An active wheel speed sensor takes voltage from the ABS module (ranging from 8 to 12 volts) and changes the voltage signal by only 0.6 to 1.2 volts. The square wave’s peaks and valleys show the alternating polarity magnets in the encoder ring passing by the tip of the sensor. The faster the magnets pass by, the greater the frequency of the waveform, which is then translated into wheel speed by the ABS module. While this explanation might be oversimplified, it is enough knowledge to interpret the waveform.
