I am new to these years and not really sure how to start troubleshooting it. I bought a 2020 and have been driving it for a few days now. I loaded up the kids for their first drive in it and only made it up the hill about 1/2 mile from the house. It was running fine then just BAM, dead, stall. Threw it in neutral and it fired right back up. Drove it back home and checked for codes. Those 2 codes showed up.
I googled and it seem the P1682 is ignition related and the P129D is FPCM but I'm curious why I'd get both of those at the same time. I googled and found some videos and watched one lengthy one. The guy found a chaffed or broken wire in the harness going to the FPCM but I was just digging around under the truck and I don't SEE anything from just visually looking and feeling around.
This is a PPV and has 2 batteries in it. They are both non-branded it seems. They both have a "window" on the top of the battery and I can see "green" inside the window. I am not sure when they were replaced.
Since this is a 2020 and it has the battery isolating relay, if the aux battery was bad or going bad, would it still kill the main battery on the pass side?
