ABS Diagnosis

According to dealer with my vin its dana- bosch u12 generation 4.so what problems could i be having with those codes i gave u.what should i be checking.thanks for your help pablo

 

So more than likely abs sensor.thanks beltrans and pablo

 

hey pablo do the harneses unplug right at the abs sensor at the wheel or are the all one piece right back to the valve.i want to check voltage at the sensor then the harness at the valve were it plugs in.the test procedures in the pdf show checking sensor at the ecu harness,which is a pain considering mine is behind, under dash.thanks
