OK, 12V is only at 25% charge but they said it is OK.

When I turn the key to the ON position without starting it up, the 12V battery & check engine light show up but the IMA light does not.

Engine Code P1639. I just looked at the service record from Jan '14 and the code back then was P1449 (followed by the note NEEDS IMA BATTERY). No P1639 back then.

when I google P1639 Honda I get "MOTB signal circuit malfunction"
