Greetings, I am new to the forum. My 2008 F250 Super Duty seem to have electronic warning issues. THe "check brake system" "tire pressure monitor fault" "door ajar" warnings all pop up at the same time while driving truck at random times. Sometimes all will be fine and other times warnings will appear but all together , never any one warning by itself. I have checked the doors and all seems to be good. One other piece of information that may or may not be pertinant - just prior to the arrival of the warnings my radio lost power so I checked the fuses.... when I removed one of the 20 amp fuses (i think 38) I diddn't notice any issues so I reinserted the fuse and the radio power came back on. I was the next time I started the truck when the other group of warnings started appearing.

Thanks,
Keith

 

Mine does the same thing!! Did you ever figure it out???

 

There is a network in your vehicle composed of multiple modules.
The radio and instrument cluster are 2 of the modules in that network.
Further testing would be necessary to determine if either of those modules is malfunctioning.
