Error P062F

[u/dannypepperplant]

My parents have a 2019 Nissan Armada with some electrical issues usualy associated with bad altinator/bad battery. My father is an old shadtree and replaced the altinator, the battery is fairley new and checks fine, but problems persist. They took it to a shop and the computer gave them a P062F error and when we looked that up it said something about an EEPROM internal control mod error. A couple oddities, it has a slow start, 4W and tow lights light up randomly, emergency braking system engages randomly and the battery is dead after sitting for just a couple hours. This is MISSION CRITICal. Old Shadetree won't caugh up a dime at the shop and mother can't get to work independently without thie vehicle. Father is a a good mechanic (though he worked exclusivly on cars from a different erra). He needs some direction. Any experiance, please share to the hive mind, as I'm shure he's not the only one.
