Mine gave out with no warning at exactly 100,000 miles! Weird.

I pulled over and towed it home - knew exactly what is was and INPA confirmed pump failure. Sounds like the impeller is jammed or something when I try to run a test with the computer.

Oh well - it was inevitable. Now I hope to get it dissembled in a few days then once circulation returns to my arms, get the new stuff installed and hope I never see it again for another 100k!!

Thanks for the handy info and DIY.
Is there a specific way to test for the water pump speed in INPA without error codes?
I'm thinking maybe we could try to read normal waterpump speeds vs slower speeds when it is failing that way we know to just get rid of it without it leaving us stranded on the side of the road.
