Anyone have experience with the following codes:
P062B
U02625
U152B

symptom: Low voltage - dead battery symptom
When boosted, throttle body and fuel pump were not getting fuel
Let sit for 10 hours, cranked but required a little throttle to get it started. Threw the above codes.
Started 10 minutes later with no throttle, but check engine light was on.

Stealership says known issue but no concrete fix other than a remap and it could happen again.

Googling those codes it looks like battery wiring, alternator wiring, injector wiring may be compromised like a mouse or rat.

Have you driven through a big puddle lately? The fuel pump module is mounted low for some reason and has a big plug that goes to all kinds of stuff. Might unplug it and see if water comes out or it looks corroded. Learned this on an older 6.2 burb

Thank you for responses. No puddles as it has been bone dry here for a month. Will check wiring. Ended up unplugging everything and plugged everything back in. No symptoms since then.
