PCM update failure

Recommended Posts

Have now had my car spend two whole days at dealer for PCM update and while they claim it is done the car is unable to run in electric mode over 62 miles an hour even if I am going downhill with my foot off the accelerator and battery is full. If watching energy screen it indicates that gas engine is on due to "high speed". Who can I contact to help my dealer understand that update did not take. Today they said that the head service tech checked it himself and "the computer said everything was up to date." I like my car but would like the update. Also said the MySync update was not covered under warranty and I'd need to do it myself. True?

I would contact Ford on Twitter or FB and open a case with their customer service department. MFT has a 5 year warranty, and it includes updates. The most recent update is a DYI update - you just need a usb drive and a support.ford.com account. Most of us have done the update ourselves, but the dealers have done it as well. I guess your dealer just doesn't want to spend half an hour to stare at the MFT screen.

 

You're better off doing it yourself, as you can drive the car somewhere while you do it, instead of having the car sit at the dealer burning gas.

Thanks for the tips! I did post on the Ford Fusion Hybrid Facebook page with no response.

 

While I am fine with doing the MFT update, I've read on here that it is important to do the PCM update first. With that hanging, I am concerned about tackling the MFT update. Any thoughts on that?

My Dealer is happily doing the MFT 3.6.2 update right now. I even received a letter from Ford stating the update was DIY or the Dealer would be do it for free, either way I preferred.

 

If the Dealer is using the old Operating software on THEIR computer they can't install the PCM calibration correctly.

You might a try another Dealer if they are that incompetent and uncooperative.

Update on the PCM update: After getting help from Ford Corporate my car has now been successfully updated at a new dealer. They were totally service-oriented and never questioned my observation which proved the first update had failed. After replacing the Audio Control Module and re-updating the PCM software, one of the owners of the dealership took it on the highway to be sure it was operating correctly. Very impressive. As for the MFT update, I successfully did that myself once Ford told me that the USB drive had to be FAT formatted.
