Parasitic Battery Draw - Recurring Dead Battery

Not sure. Usually corrosion tends to stop current, not send it through when you don't want it.
Also, since the BCM controls its power, it says hot only in Start/Run, there shouldn't be current getting there in the first place.

My humming noise is back when the vehicle is off. I was finally able to get a video of the sound today
. Sound seems to be coming from the transmission. Like before, pulling my PCM relay, Fuse 26 (Powertrain control module – keep alive power and relay coil, canister vent solenoid), Fuse 53 (Run/start – Powertrain control module), Fuse 75 (Powertrain control module – voltage power 1) or interior Fuse 18 (Brake-shift interlock, Keypad illumination, Powertrain control module wake-up, Passive anti-theft system) will make the humm stop.
Any one have a guess?

How did you make out on that? My gremlin is back aswell was fine for 3 months now dead twice in 2 days over nite drops battery to 7v. Damn frustrating have already greased the connectors few months ago and it’s a column shift 13 crew any thoughts?

I wired in a switch to Fuse 53 (run/start - power train control module). I used a fuse tap and a normal closed switch inside the cab. When I park I just press the button which acts the same as pulling the fuse and putting it back. This stops the humming and the battery draw.
It's the only solution I could think of and I haven't had an issue since although it has not gotten below freezing yet which is when the draw really caused a problem with the battery.

I'm having the same problem with my 2014 and I've been pulling fuse 53 every time I park for over a few hours to shut off the system. The switch idea is good and might be the best work around but is a bit unsettling that it doesn't address the root cause. Any more luck in determining the problem? Its getting cold out there.

I had the same over night dead battery problem.
Getting the shifter changed next week.
