I might have to borrow that scanner from you. Still having the issue on my Titan with the compressor shutting off in extreme heat. I changed the fan clutch and thought that fixed it until we got into August. I think it has to be the high pressure switch and whatever OEM setting the system considers too high. It’s a common problem on Titans and the forums all say fan clutch or software update. Already changed the clutch and the update isn’t applicable to my VIN. Kind of out of options. I ordered a new HP switch which is conveniently on national back order…

I’m actually thinking about adding an electric fan to the condenser. I got it to shut off in the driveway the other day and it took about 2 seconds of spraying the condenser with a garden hose to get it to kick back on. Hence the assumption that it has to be high pressure related.

I typically have a scan tool at work in my filing cabinet next to the sups office you are more than welcome to borrow it.
