theres a good chance the low voltage took out the ficm
Either a bad batterty or a bad alternator or both
FICM voltage needs to be checked after cold soak first start If it set a code for low ficm voltage at sometime voltage dropped below the allowed limit even though you saw good ficm voltage
tell them to fix it or give you a deal on it
did you check eot vs ect deltas

I did the FICM test first thing, the EOT and ECT temps were ambient, and they said nobody had driven it that day, I believe that.
I'm going back this week to take it out on the highway and get it up to full operating temp, but I told them they need to take it to a Ford dealer and get it fixed before my next test drive.
I also asked them to have an updated EGR valve put in it.
For testing with the edge I turn the key on, the unit powers up in a few seconds. It will show the ficm voltage, you can then watch it as you start the motor.
Perhaps I am missing something, but I guess I don't really care when the issue happened, I just want them to fix it or I will walk away.
The truck is a 2006 CC LB Lariat with 100k. I can look at blue book values all day, but what is the going rate for one like that in good shape, or with the current issues?
From working on my 04, I think I know just enough to be dangerous about these trucks, anything else to look for?
oh your ok then if it will show ficm voltage at koeo
just saw a thread yesturday where an edge insight I believe would not show any pid info untill truck was running didnt know if all edge was like this or not
koeo = Key on Engine off
and another one you may come across is
koer = Key on Engine running
did you look at coolant bottle any sign of puke or was it too clean
did it have the famous bell housing drip
did you look at the filter minder

How long does it take for low voltage to ruin your FICM? One day, a week, a month, three seconds?.
That's a good question I'm not sure I've seen answered. Proabably depends on a lot of factors though.

Are you talking about my post about my insight not coming on at koeo? If so I have thst resolved. You have to touch the screen to turn it on. At least for the new ones. In that thread someone said their older one comes on by itself in a few seconds like the op in this thread.
ther is a tsb for the p0611 code.has to do with the positive cable that supplys voltage to the ficm at the drivers side battery getting dirty and not allowing enough juice to the module.bulletproofdiesel.com can fix the computer for 300 bucks with a 1 year warranty

i started getting the ficm code and also low voltage codes for injectors. checked my batteries and they weren't holding enough charge anymore. 10.5 at startup cold. they truck was also taking a few seconds more to crank. i've replaced the batteries and now doesn't drop below 12 even with glow plugs, then jumps above 13.5. only been a few days, but truck cranks noticably better and hopefully my ficm wasn't ruined. just waiting now and keeping fingers crossed cel doesn't come back on.
