abs/traction control/brake light is on

...am going to guess one of the transistor level technology sensors to the wheel cable has gotten injured, or communication to the ECU on a transistor level is comprimized/injured...probably going to be a harness to the rear wheels~

had front bearings replaced one and half years ago. six monthes later abs /trac come on replaced the passengers front bearing light out . now th service soon/abs/trac/brake ligt is on plus cc inter ference. what do you think all this could be.

Having exact problem on my identical grand am ('02 4cylnder coupe) planning on replacing the front wheel hubs on Saturday to see If new sensors will do the trick, I'll post my results after the installation. Please share any progress u make, this issue is very frustrating.
