Ok trying to figure out what the deal is just the other day my 2021 F250 tremor with a 7.3l engine started doing a short 3 honk burst every time I start it. I’m trying to figure out why it’s doing that. I’ve checked all the doors tailgate and hood are shut good. No lights no warnings and it’s been doing it every time wether it’s the first start of the day or if I stop for gas and restart. What is it trying to tell me? I’m thinking maybe key battery is low maybe I don’t know just curious if anyone else has noticed this and found out what it is.
