I'm having an issue with my father in-laws 2005 4x4 Envoy.
The ABS light came on a while back and I just didn't have the time to look at it. A few weeks ago it started to pulsate every time you hit the brakes.
So finally got around to it last weekend. I have ScanXl and am unable to connect to the ABS system. I can connect to all other systems.
So I checked the usual ground under the drivers seat. That looked pretty good but I cleaned it up anyways. Didn't do anything.
So that it would stop pulsating until I figured out the problem I pulled the 60amp fuse. However, at higher speeds when you apply the brake it still pulsates. I thought by yanking the fuse that it wouldn't do this.
I am thinking the controller but thought I would seek opinions. I attempted to take off the controller but the darn torx screws are filled with crap and the clearance between the floor and controller is such that I can't get anything in there to loosen the ones closest to the frame. Looks like I'd have to take the whole assemble off.
Would love to hear anyones thoughts.
