Impala ABS Scan Tool

I have an 02 Impala with an ABS light that comes on. I suspect the cause is the wheel with the wheel bearing that makes some noise. I'd like to buy an ABS scanner that will identify which wheel generated the ABS cose and also help locate the bad wheel bearing. The last bad wheel bearing I replaced was also the cause of the previous ABS light coming on about a year ago. I waited until the wheel bearing was very loud but I don't want to wait that long again.

Thanks for the help!

Many companies make just an abs scanner, google it and you will find plenty.
