The VCM can apply the brakes. That's what the pump is for. It can apply the rear or front as needed to try and get you out of trouble. It's not clear if the front each side can be applied independently. In the service manual. But I believe it can. There are only 2 pumps driven by 1 motor but valving should be able to independently control each side.

I found out years ago. When I put a Kumho tire on the back of my STL. It just did not stick to the road. When the tire broke loose suddenly. The stability system was just was not fast enough and I ended up backwards on the shoulder of the road.
