2010 F150 Super Crew 5.4. 60,000 miles. Getting "Tire pressure monitor fault" followed by traction control symbol alternating back and forth. Turn signals go out on dash but still work outside. Step on brakes while moving to slow down and you can feel the shift interlock switch engaging through the shifter. Also, walked past the truck at night and the dash lights were on with the light switch in "Auto". Turned to "Off" and they went out. Also door locks don't auto lock until 30 mph when all of this is going on.

Anyone have similar problems? What fixed it? Called dealer they said a scan may not detect the problem. Anyone know anything about the "Smart Junction Box" located behind the passenger floor kick panel?

Thanks in advance,
Dave

 

Having the exact same issue on my 2010 F150 Supercrew. Did you get your problem resolved? If so, what was it?

 

Never got it fixed. Traded the truck in for a 17 F250. When I was trading it in, they said there was a disconnect between the smart junction box and the dash module.
