Anytime your ABS warning lamp is illuminated does not necessarily mean your ABS functionality is disabled. If you have a whining in the rear of the vehicle you could potentially have a ton of different issues. Wheel bearing, bearing issue in the rear differential, over running clutch for the rear drive either in the PTU or rear diff assy, etc. it also could be as simple as a low fluid condition in a driveline component. GM dealer is the way to go especially for a late model Pontiac AWD. That chassis is fairly in depth
