ABS system

I have a 95 bonny SSE.....my ABS light is on now! I am getting a full diagnosis this weekend, any ideas on the ABS part though?? It's making a wierd buzzing sound coming from the front drivers side in addition to this-it's a new noise, came at the same time the ABS light came on.

Faulty wheel hubs can cause the wheel speed sensors to fail. This will cause an ABS light but there are many more possible suspects. The diagnostics should specify where the problem is though. You might get a code that means "right front speed sensor erratic" or "no signal".

Let us know what the verdict is after you have the codes read. My ABS light has been in my 93 on since I bought it. I took it to a shop and they said that the scanner would not even communicate with the ABS module.

I got a 93 ssei that has had the ABS light and traction control light off, on for a month now. New rear brakes were put on, as well as master cylinder. I suspect a wheel sensor, but which one is beyond me.
