Sensor was replaced but abs light still on

Sensor was replaced but abs light still on
The light won't go off on its own, it needs to be reset using a scan tool. If you reset it already and it came back then the harness that runs from the speed sender into the body may be faulty or the abs module needs to be rebuilt from a place like modulemaster.com

Was told that scanner is unable to read codes
What type of scan tool? Where did you take it to get scanned? Does the car have an aftermarket radio?

No , the mechanic tried to scan after sensor didn't work
What type of scan tool, what type of shop? So it has the stock radio?

What is stock radio, what type of scanner is needed
There's many different options for scan tools. I'm asking if the radio that's in the car came with the car or not?

it looks to be factory to me
Ok, well the abs module is probably faulty and blocking communication. Why was the sensor replaced?

Danny
Customer: replied 4 years ago.
they thought that was the reason the abs light was on
Right, I get that part but were they originally able to scan it before the repair?
Customer: replied 4 years ago.
there was no need to until they replaced axle
Yes there was, that's how you diagnose cars. At this point they need to try connecting to other control modules and if you can't connect, disconnect the abs module's connector and try again. If you then have communication the abs module needs to be rebuilt. Modulemaster.com will rebuild it much cheaper than a new one, these are a known bad part that have a defect whixh the manufacturer never fixed so don't buy a new or used one, have yours rebuilt.
