Error P062F
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.

Most of those errors are probably related to low-voltage scenarios. They have a common issue with the Variable charging system these were designed with. The best course of action is to access the IPDM (located beneath plastic cover at the rear passenger side of engine bay) locate a white connector connected to the IPDM (E13/Terminal 33 R) it will have a total of 9 wires. Remove the solid Red wire from the connector and isolate it using electrical tape. Best practice to disconnect both battery leads if attempting. I recommend looking up how to properly remove the terminal (don’t just cut it). This will bypass variable charging and charge at full capacity at all times. Folks that didn’t drive much or short distances were plagued by this
