My ABS light comes on every time my truck hits about 15 MPH and stays on until I get under that speed. I'm having some issues with my left wheel bearing, which is going to be replaced under my mechanic's warranty. If the new wheel bearing (hopefully a good one this time; the 3rd time should be a charm) doesn't fix it, what could this issue be?

 

Since the light is on, there is a code stored in the EBCM (electronic brake control module - aka ABS brain). Get the ABS system scanned by a capable scan tool and it'll tell you what it is complaining about.

It is possible that the fubar'd bearing is causing it.

 

Thanks. I'll have to get that scanned. Hopefully it's just the bad bearing causing it.
