A0 not starting when plugged into OBD port and wrong boot mode board fix

A0 needs reset button pushed to start code when powered through the obd II port.
changing C27 from .1uf to 1 uf corrects this.
The EN/IO0 toggle doesn’t work initiating boot for loading code on some laptop and cable combinations and doesn’t put the module in boot to load code.
changing C27 from .1uf to 1 uf corrects this.
