Electrical system drain service required: Fix #4

[SSNutz]

Anybody have experience with the titles error message? Truck goes into deep sleep. I don't have devices connected, 12v battery (1.5 years old) is always above 85% SOC. Any thought?

I usually get this if I've left my Obd2 adapter connected overnight. Less so with my hardwired dashcam. Long story short, there's probably some draw from an aftermarket item or, if you walk around with your phone and have PaaK enabled or your fob, it might be triggering a frequent wake up without you knowing.

My LVB SOC was also usually around 70% when I checked it with the message. Would also happen when it was plugged into my L2 EVSE at home. I'm looking into a Noco Genius 2 battery tender for some peace of mind.

I just got my 2024 Lightning back yesterday because it was going into sleep mode because the 12v was being drained. The battery was fine. The issue was the keyless entry #pad was waking up modules and cause a drain on the 12V. They replaced that and over night my 12v SOC was 98% today. So many things can kill that poor LVB!
