Testing ABS Sensor
 

So what is the procedure? Ohms test? Are they replacable or do I need to replace hub? ABS, SES, trac loc etc... lights are on. 40k miles. No noise. Trying to run down which side? Doe rear hubs have the sensors as well?

Have the computer read it will tell you which one threw the code (hopefully). You have to change the whole hub. Yes the rear have sensors. The search button will point you to the threads with more info.
