Honda/Acura ABS testing, code 1-2 (failed ABS pump motor)

This is one of the many videos I have available covering the subject of bias voltage, and how the can help (or hurt) you if you’re not aware of it! I demonstrate how to use bias voltage to your advantage, as well as methods to recognize the presence of a bias voltage in the circuit you’re testing. Be sure to check the related videos below for more information about bias voltages.

Engine Performance Diagnostics chapter 3 page 26
