"battery doesn’t charge" is not the thing to say to a car tech as it DOES charge in MM mode..
Need to see why it will not charge from the charge port.

also need to see if you have had all the software re-programming in past recalls.

one step is to just remove a plug on the battery and look for ( water ? )
------
When my battery cooling tank float CABLE was replaced then the diagnostic test showed a completely different
(and correct ) battery isolation number.

I think it is a testing process
as more items in the test get run and pass more tests are then run

plus some of the recalls changed the firmware to allow (short answer - different values to pass- )

I would not expect a diagnostic machine to print a value as zero when is was really " test not run"

My dealer said they need a volt tech to run their machine when testing volts.
