Alarm

[dna9656]

I have a 2015 LTZ 4 X4 4 door, short bed pickup, 5.3, 6 speed, 140k miles.

Early this morning the alarm goes off, twice. It was REALLY foggy all night, the truck was covered in condensation. My theory is humidity got some where and caused current to pass though a switch or sensor and activated the alarm. I realize some one could have been tampering with the doors but the dome light was not on and it's in a very well light area close to my home. 

So,another question: what functions does the body control module control, is it in this picture?

My 2018 Silverado alarm kept going off. Replaced hood latch no problem since.

Wow, who'd thunk that? 2000 and up trucks are over engineered!!!! 

Thanks!!!
