Today I experienced an error that I do not recall seeing on the forum. I also searched and did not find the issue, but I could have missed it.
I was running errands and after my third stop, when I started my truck it would not shift out of park. An icon on the dash display erroneously showed that the truck was connected to a charger, and there was a pop-up message to disconnect from the charger. (I was not connected to a charger.) I started and powered off several times, pushed the release button at the the charge port several times, and re-booted the main screen, all without eliminating the error. On two occasions upon starting the red 12 volt battery icon displayed. I plugged in a cigarette lighter USB charger with a voltage display. It showed 13.6 volts with the truck started and 12.5 volts when powered off. Everything else seemed to work properly. The AC was running, both displays were normal except for the connected-to-charger icon on the dash display, and the frunk opened properly. I have had the 12 volt BMS module replacement completed.
I pulled out the 10 mm wrench I purchased 18 months ago and lifted the negative cable off the 12 volt battery. I waited about a minute and reconnected the cable to the battery. The connected-to-charger icon was no longer present on the dash display, and the truck would now shift out of park. If I did not have the 10 mm wrench, I would still be sitting in the parking lot waiting on a tow truck to the dealership. I checked the battery status with an OBDLink MX+ and CarScanner when I returned home (only 1 mile distance), and found 12 volt SOC at 80% per the attached photo. Although the display is showing 102 degrees, the ambient temperature is 85 degrees. The truck is parked in the sun after driving it, so heat from the radiator is likely affecting the display temperature.
If you don't have a 10 mm wrench, you surely need to get one. This is the first time I have had to use mine. I am not a fan of using a 12 point wrench on hex head nuts. I have a 6 point box end / open end wrench, but it was a bit unwieldy. Here is a link to a ratcheting 10 mm 6 point wrench that I just ordered.
