LoL - I actually tossed a pair of gloves at the hatch latch but heard a telling click while I was dealing with the glovebox and sure enough it had partially latched despite the gloves. I guess they were too thin! Ended up using a jumper pack under the hood just to get the hatch opened, but it made me think there must be a safety relaease somewhere in the trunk area that I should learn about. I could reach the trunk from the back seat, but couldn't get the tilting floor piece out of the way to reconnect the battery without re-opening the hatch.

Wheel speeds or tire pressures? I thought those codes were just for tire pressures... I think I mentioned it earlier but the lack of pressures is only since swapping to the winter tires. I assume they either don't have sensors or perhaps all the batteries are dead. I did have working tire pressures with our original 19" summer tires, which were still on it when this power steering issue first ocurred including for a subsequent highway drive through a blizzard where AWD worked quite well. I'll see if I can find an old pre-PS-failure scan to see if those were ever present before.
