Rebuilt entire front end on the car when I got it. (Has 246000 miles) New axles, rotors, calipers, pads, lower control arms upper control arms tie rod ends, struts, ball joints hubs and bearings. Started this random light issue after I replaced the passenger side items. Replaced both speed sensors just to be sure. Yesterday I bled all four wheels just to eliminate possibility that pedal travel was the culprit. Still getting the light and ABS trigger. Lights are on when I start the car, then they'll go out as soon as I'm under way. Car will be fine for a few minutes and then I'll get the pedal vibration ABS trigger. My obd scanner doesn't read ABS codes.
Can the module be read with an ohm meter? Are there specs? Or is it time to just buy a new module?

 

Stop by an autoparts store and have them scan for codes. Their code reader should give you abs codes and give you a place to start troubleshooting.
