Ok folks - my 2010 4.8i started up with a Christmas Tree dash after sitting for 4 months on a battery tender.

The transfer case ECU looks perfect and my Indy checked and cleaned the connector pins (they look fine). The actuator motor gear is good (A700 case) and the motor was swapped but issues remained. Codes return immediately when cleared. Car drives fine although I have not “tested” ABS.

Here are the codes:
