I’m baffled

[TerryP]

I’m new in this forum, so please bear with me. I’ll give a rundown of what my truck is doing, and hopefully someone can help me out.

Drove the truck Thursday with no issues. Truck sat Friday without being driven. I went out Saturday to a completely drained battery. Charged it and started it only to find the SERV 4WD alert with the check engine light and my shifter says it’s in reverse when it is clearly in park. Took it to Advance Auto to run the diagnostic check. Came back with the fuel pump control module error saying that the module is stuck open draining the battery. So, I ordered the module to replace it this week hoping that will take care of the battery draining. Then I noticed that my instrument panel lights are staying on draining my stupid battery.

1) How can I alleviate the instrument panel lights?

2) What is making the SERV 4WD light come on and all the other stupid electronic errors? I’m hoping and praying that it’s something simple as I’ve only had the truck for 3 months.
Any help is appreciated immensely.

Update: I pulled the fuse for the instrument panel lights which stopped my battery from draining for a few days. changed the fuel pump control module, and came out to a drained battery again. I still have the check engine light and the SERV 4WD lights on. I’m going to take the truck to a mechanic to try and get this resolved

I would be putting my trickle charger (well, smart charger is the ticket nowadays) on the vehicle until you get this resolved. save your battery probably

No other codes show up?

I was thinking maybe tipm issues but I don't know what you mean about replacing the fuel pump module because it's integrated into the tipm (and a common first issue to have if the tipm is going bad)

With served 4wd showing I figured there would me more errors showing up.

What year truck? Still under warranty?

I’ve been disconnecting the battery while the truck sits for an extended time. It’s a 2013, and not under warranty. I will take it to get it checked again when I get back into town.

OP, you're having similar issues to what started in my 2010 Laramie, except that my truck is no longer starting whatsoever and has been in the dealer shop for over a month and a half now. The longer it takes the more I read up on issues with Chrysler's electronics. TIPM, WIN module, fuel pump, you name it. Nice looking and driving trucks these generation 4, just don't seem to be built to last too much beyond the 5-year warranty period.
