97 2.2 abs light on can scan tool tell what sensor

hi hopefully someone can answer since from my other topics no one can answer sun fire questions guess there isnt really much problems with it or no mechanics work on them

but my question is this

ABS light is on i already replaced the rear hubs and re plugged wires into it but light still on

will the obd2 scan tool or scanner whatever one is better tell me which sensor is gone if its the 2 front hub ones or the 2 sensors in the brake cylinder under the hood since the rears are brand new
