2002 GMC Sonoma 6 cyl Four Wheel Drive Automatic 87000 miles
abs + brake trouble lamps come on at same time. Usually when starting, after lamp test the 2 lights come back on until the nest start cycle.
dealer read NO code but determined the control valve oump had a fault. I later found out that this would have produced a fault! The valve ($800) was replaced but the same condition still exists.
What wpuld cause the false triggering of these 2 lamps?
