Service Shifter & Fault Codes

[jdflyer]

Hi Everyone,

I have a 2016 w/~104,000 miles on it. I also have the GDE engine and transmission tune on the vehicle.

This morning I took the vehicle to a car wash (hand type) where it was driven into and out of the wash area. When I went to pick it up at the detail area I was told they were unable to move the vehicle and that it would not shift into gear. I had this issue for about ten minutes after I got in the truck but after several attempts was able to finally get it into gear and drive it home (about 2 miles).

During the drive I got the "Service Shifter Message"

I used alfaOBD to scan the shifter and got the following codes:
U145D
U0074
P0705
U0002
P0919
P0607

My thinking is that they somehow sprayed water at the OBD connector under the vehicle and it has caused a bunch of errors. Would like to get everyone else's thoughts since I am an amateur mechanic but really don't want to have to take it to the dealer.

Thanks

More likely is a voltage issue, check your battery health.
Also low fluid can cause the transmission to not match the selected value (PRND etc). Fluid level rises as the tranny heats up.

Take a look at the large plug under drivers side on the inside of the frame rail. They’re a weak spot for poor connections. Pull apart and dielectric grease it
