SOC % dropping as soon as I turn truck on

[The Weatherman]

I have noticed my 2022 Lariat ER after being set to charge to 90% will jump to 91% after pulling out of the garage.

I have chalked it up to temperature variations.

The diagnostic tool they use is FDRS. There are other specialty diag systems just for the HVB however.

Point being .... does anyone in that shop know what they have and how to use it?

If you have Car Scanner, in the default dashboard, you'll also see that the HVB SoC is measured to 2 decimal places but the GOM is to one decimal place while the display SoC is to the nearest integer. This means that if the actual SoC is at 90.30, the GOM will show 90.5 while the display is show 90. If you disconnect shore power and start the truck, it will immediately draw the small overage from the HVB and the display will drop to 89%.
