I came out to my truck yesterday and started it via the pushbutton. I heard the ba da dah, ba da dah, ba da dah that I haven't heard in forever. There were no indicator lights or messages on the dash. A few minutes later, I noticed that the warning tones from my backup assist system were different too. Years ago I made some Forscan changes, although apart from the "Licoln Mirrors" I can't remember which ones for sure. That may have been the last time I heard the startup chimes, but I wouldn't swear to it. Did my truck take a wireless update via my home wifi? It was only sitting in my driveway about an hour and I'd swear all was normal when I parked it there. I checked the "About" screen and got "Sync 3 Software Version 3.0 Build 19205_Product. Gracenote Version 1.1.1.1139(NA-0010)". Is this a new version or is there something else screwy going on?

 

I noticed the same on my truck a few days ago. I know for a fact it was not connected to my home WiFi. ??

 

Just the two of us? Weird.
I was glad to see your reply though just to tell me that I'm not imagining it.
My Forscan mods haven't changed. Everything still works as expected.
I have no idea what happened.

 

It is the self-destruct warning. You have 6 months to trade your truck on a new one or the turbo will explode. A new COVID-19 workforce employment strategy in the works.
