This message comes and goes
Some times will trigger alarm system
Unlike older systems I can't find button type or other obvious trip switches to check. "How does it know"?
Doors open or closed... Is it a CPU problem ?

Most common to be is a door switch
check door hinges at 1st
2nd use penetrating oil and spray in each and every door latch
open and close door few times and spray again
most times that work ,but if it didn’t have to have a scanner and check which door switch that is staying open and replace
door switch is located in ,on the door latch and door panel need to be removed to gain access to it
good luck

Jack O, "BMRFIXIT", I followed your instructions, one door at a time, the problem appeared to be rear lift gate. My wife is soooo happy and so am I. (2carpros.com) and you Jack O have made me a hero...
Thanks very much guys,
Jim "O'B"

P.S. I bought an Auto Inginuity Item #SP03 Ford Enhanced Scanner also. We own 3 late model Ford products & usually keep vehicles several years (10 or more). Got the Mitchell on-line Manual 1yr.
I was hoping to get a package deal on all three models we own. If you know of combination like that let me know: 01' F-150 4x4, 03' Explorer, 05' Five Hundred.
Again, You Guys are "The Greatest"
