Double honk on start

[jsalbre]

For the past few weeks about every 3rd time I start the truck (with the dash button, not remote start) the horn honks twice.

Anyone know what the deal is?

I recall reading about that either on a 1500 or 4th gen forum. It's been a while, so I can't say for certain, but if I recall correctly it was attributed to starting it while the door is open.

I read of this happening when a tire's pressure was off. Also maybe when the tire fill alert on. It was informed guessing I believe and not an exact solution. Good luck.
