Why two Beeps?

[JohnHaggerty]

Everything running good. I get two beeps. Louder (deeper tone) than a chime. This has happened twice recently. Any ideas? Thanks!

It will help if you describe what the status of the truck is, right at startup, shutdown, driving down the road, etc.

Occurs when driving down the road at 65 mph. Everything seems normal then two beeps and no CEL. Has happened twice in the last month.

I am going to challenge the conventional wisdom that there are no dumb questions... ;-) but do you have any other items in your truck that are electric/electronic... I ask because I have a Garmin dashcam that occasionally beeps at me (it is voice activated and sometimes it thinks I said "hey garmin" and beeps at me). Trying to rule out any non-OEM truck related items.

Different sound then the seat belt reminder?

Along with what @bigceltic is saying, my GPS dings when approaching a school and RR track crossing. First time it did it, I thought CEL!

So it's a beep and not a chime? Most alerts from my trucks and Jeep are chimes. I tend to agree ot sounds like an alert from the navigation system.
