I have a 2004 F250 6.0 diesel truck with 93,000.00 miles. Only problems so far is having to replace the turbo charger two times under warranty over several years. Lately it started idling rough after engine is warmed up. After I take off runs fine. Ford dealership said needs new FICM. According to a “technician FICM guide” the most common symptoms of a failed FICM are no start or constant misfire at all engine temps. Of course my warranty time (5 years) ran out in July. Cost of replacement is $1000.00. I use this dealership for all of my service and repairs and have no reason not to believe them. Just don’t won’t to start down that road having to sink a lot of money into this 6.0. Does this sound about right? Thanks for any feed back.

 

My opinion..... Shop around ther is a upgraded ficm that international and ford use. The last numbers for ford are something like c6. The international idm (what they call the ficm) is the same as the ford and if you buy a new one will have to be programmed. You have a few options such as the fte parts guy which can get you one generally cheaper than the dealer. When I looked I found that I was looking $650+ dependant on the dealer. That is parts only no programming. Another option is to use the ebay guy that offers a life time warranty but you have to ship the ficm and pcm so he can program it and send you the rebuilt unit. Me personally I would buy a new unit or find a used one that I was comfortable with then contact eric and innovative,or bill at power hungry performance and let them custom tune the ficm. Eithers tuning is suppost to gain mpgs and offer better throttle response and more power.

 

Unfortunately, they're probably right. If you can't find a used FICM, we do have some in stock (used) and can program it for you for considerably less than purchasing a new one from FORD. I've also heard great things about Eric at Innovative's FICM reprogramming, so I'd give them a shout and see what they have to offer, too. Good luck!

 

The FICM guide is a bit misleading and I think must have been written before what seems to be the recent flood of bad FICMs (at least it seems so on this forum). It may be correct that a failed FICM will cause a constant misfire, but maybe not a failing one, which seems to be pretty common. It seems that these things can cause anything from hard starting at cold, to good starting but rough running at cold, to general stumbling, or any combination of the above. From my little bit of experience, if the tech knows how to read a scan tool and has verified that the module's wiring harness isn't chafed through, then it's a pretty easy thing to diagnose.

 

Thanks for everyone’s quick replies. Got the truck back today, runs fine. Just didn't have tome to shop around as I drive the truck everyday for work. As I said before my warranty ran out in July, just my luck. Did not know that about the FICM guide but, that good to know. I really like the fuel mileage I get with the 6.0 just not all the problems. Thanks again.

 

Was too quick to talk good about the repair. Took my boat in on Friday for a local High School Parade. (11000lb boat) No problem pulling it into town (6 miles). Stopped and waited for parade to start (45 min.) Was hot so cranked up the truck about 5 min. before the start of the parade. Parade started and truck would not go. No power!! Would idle but, that’s all. Put truck in neutral and revved RPMS. Would only go up to 2000 RPMS at first but then would go up to about 4000 RPMS. Put truck in gear and made it thru the parade with it running rough and not much power. Stopped to unload girls cheerleading team and went to go home and truck ran perfect. Still runs rough at idle speed. Took it back to dealership today and told them to keep old FICM part just in case.

 

Dealer called and said that I had a bad injector. They are offering to replace the injector and split the cost with me. Could this have been the problem all along and not the FICM?? Thanks…

 

pate when we diag a failed ficm we look at a few things. first for ckt hi/low codes to the injectors. we also look at ficm power wich if all is happy would be ficml_pwr 12v ficmv_pwr 12v and ficmm_pwr 48.0v. the min ficm m power is 45v.if ficm m power drops we should be looking at the charging system as a possible cause of frying the ficm. It is not in heard of to have a faild ficm take down an injector, as well as it is also possible to have a failded injector cause a ficm to fail. I would revarify that your batteries are healthy and your alternator is charging as it should be.
