AlfaOBD and RF Hub

[rfullen280]

So, strange anomaly on a road trip this last week. Somewhere south of Wells Nevada, on highway 93, my TPMS warning light came on, and the EVIC said "Tire Pressure Unavailable".

I did what any good geek would do. I stopped, broke out my laptop with AlfaOBD, connected to the truck... and the BCM had no errors. Great! Then I tried connecting to the RF Hub (2021 Ram 2500). It would connect, then disconnect, then give errors... finally if I would connect for a half second, I could read codes, and found this error "Error code: C151D Tire Pressure Sensor Location Undetermined". Either way, it took about 20 minutes to get the RF Hub to connect in a stable fashion, before I could clear that code.

Then everything worked fine... for the rest of the drive to Flagstaff..

Now, here's where it gets weird. A week later, driving back through the same spot... The TPMS light came on.

Would you believe it was the same error, in nearly the same location? And the same difficulty in trying to connect to the RF Hub? I finally got it to reset.

Either way, super weird... any ideas?

Aliens!

Maybe atmospheric pressure change between mountains...sudden altitude change?...

Ya, I dunno. It was fairly stable outside... no big power lines or anything visible that could interrupt RF.

What I found more interesting though was the difficulty in getting the RF Hub to connect using AlfaOBD.

Not sure what's on those mountain ranges. Possible antennae farms could produce EMF, but I would think it would affect other things as well.

Edit...depending on the frequency.
