Four days is a good sign. I hope that's the last of that issue. Keep us posted.

 

Well it officially has been a month without any more issues. So I am going to take it back here in a week or two to have my remote start put back hope all goes well.

 

HELLO SIR!
ANY update on this issue? i have the same problem with my 2007 expedition EB.

 

After replacing start/stop relay haven't had any more issues, . They had also thought it was a bad bad epc board had it replaced first, but it continued to do it until relay was replaced.

Actually, I first changed the BCM of the unit and they reprogrammed the key to match the BCM. After a month, this problem occured. Do you think this was the cause of it? maybe they didn't program the key well? or this was caused by something else? is there a possibility that the key looses its program?

 

update:
my PCM got wet. Anyone knows why it happened? as far as i know, the PCM is sealed.

 

I wish I had found this trend before you gone through all this. I own and operate a small shop in northern Michigan.
I had a customer with same problems on a 2000 Expedition. The Ford dealership sends me all there problem child's they can't figure out. Dealer changed out the PCM, ECM, climate control unit and cluster. Here's what we found after extensive going through the whole system. After pulling the wiring harness for the ECM and also the PCM Communication cable we found there was no shorts in that but what we did find was from the steering column. Down in the column runs the wiring harness that has a ground wire that broke and it was caused by the shifter that's in the column. It took us six days to figure out exactly what was happening. We traced every wire on that vehicle from under the dash to the motor housing. We found that it was a manufacturer defect at time of assembly. We billed the dealership 67 hours. Talking to Ford engineering in Dearborn for over 15 hours. They were truly stumped. Good luck with yours.
