My daughter complained that the anti-lock brakes are kicking in when braking, more prevalent during cornering. She is not getting any kind of indicators on either the dash or the DIC. I assume that I have a sensor going bad in one of the bearings, but, how do I determine which one. Any diagnostics I can perform to at least narrow it down? Or, anything I can check?

I did a search and didn't find much.

Thanks in advance,
John
