ABS failure

[chrisa66]

Hello, I am looking for some insight on abs issue's. The other day the dash lit right up, ABS not working , traction control not working. I had a neighbor , who has one of the best analyzers that i have seen , outside of then dealer come by and read the codes. Left front tone wheel, XC60's don't seem to have one. So I assume the bearing is it. I replaced a sketchy sensor( cheap enough) , but it has not solved the problem. Any insight and help would be appreciated.

What about the tone wheel? Is there a problem with it? And what is a "sketchy sensor"?

Thanks for the reply, The "sketchy" sensor was a case of I wasn't sure at the time. It was an ATE sensor from FCP. To be sure I did a swap and replaced it with a Volvo part from FCP and will return the ATE one. I also did a swap with the working RT side sensor, with no change. The sensor doesn't read "0" , it fluctuates form 1 mph to 6 mph. As soon as the car moves, it spikes to 158mph. All other sensors read correct. I am using a reader with live capabilities. There does not seem to be an actual tone wheel of these cars, I assume it is built into the wheel/hub bearing assembly. Unless there is a way to zero the value of the sensor, I am going to replace the wheel/hub bearing assembly. Has anyone else had these issues?
