I have a friend with a 99 Regal LS that had the ABS light on full time, I scanned it with a Snap-on Modus scanner found 3 codes all for RF sensor. Once I checked it out I found the connector torn right off so a new hub was installed,and codes were cleared, as soon as the the car was started the ABS light was off but when driven a couple feet it was back on, I then scanned it again and there are no codes present. If the car sits with the ignition off for a long period (overnight) once started the light is off but when moved it comes on. I had the scanner connected and drove the car and it shows that all the wheel sensors are working and pretty much the same except at the initial point of movement they are jumbled but once rolling they match up . Does anyone know why this light is still coming on ?
