I have a Matco Interceptor 5 scanner , that's how I got all the codes .

Ok I'll start with that right now . I have multiple parts trucks so I can pull sensors and even GEM and try that .

Fix the B1450 GEM DTC and all the wheel sensors will go away. They are missing signals/power from it.

Do you think it's a bad GEM ?

Man.... I thought B1450 was the wiper circuit.

<------ still thinking it's a wet GEM module.

Has it rained/snowed, or anything lately Big D?

BTW, My Expedition had the B1450 code, which is why I thought it was the wiper circuit. I replaced the MF switch, and all the relays thinking it would clear up. It also had issues with the ESOF working properly, and would not go into 4 Low, and sometimes not A4WD or 4 High. In the troubleshooting of the issues, it threw me a dead giveaway two days later though when the truck tried to start on its own.

It's rained and snowed a lot recently although the 4 low problem started a while back .
My truck has a sunroof that is ALWAYS getting the drain holes plugged up and water will drip out of the bolt hole cover on the Oh Sh*t handle .
I will try changing the GEM today if I get a chance and see what happens .

My scanner says the B1450 code is - upshift selector / wheel plus switch malfunction low input
I'll double check later today and make sure I write the numbers for the code correctly .
