WARNING Ficm module

Rate this topic


Recommended Posts

Headsup guys,We are experiencing a bad batch of rebuilt ficm module. I,ve replaced one last week and came back monday morning, the ficm Lwr, Ficm vpwr and mpwr are low just after turning key on, it will take 10 to 15 seconds to come back to normal voltage.I,ve performed the tsb procedure completly, load test all power circuit and ground circuits and all ok. replaced ficm module again and same concern.Called Hotline 3 times and 3 rd timehad a good guy telling me they had a mmeting yesterday about this issue. They recommend me to swap ficm with a known good vehicle. Now the low voltage would follow the bad ficm. Hotline are all aware of this issue and are looking into it. Now i was told to reorder another and see what happens. Note the ficmLpwr would start at 3.5volts and ramp up .5volts upto battery voltage. Anyone has gone through this now?

Thats a little scary. We have replaced a ton of FICMs this past winter. I even did one last week as a side-job. The guy bought a brand new FICM in a ford box for $400.00 off of ebay.

It seems that whenever they have to step up production there are problems.

Jeff I was told by hotline that a dealer in Canada had the same issue, they were on there 3rd rebuilt ficm on that vehicle, tech was going nuts so finally took one of a known good vehicle thatactually worked and his truck was ok after, the concern followed theebuilt ficm. Is this your dealer. I have over 4 hours of fucking around with this Van and following hotline recomendation and telling me that i was doing somethingwrong or overlooking something until I swap one from an 08 Eseries that was next to me for an oil leak.I just hope to get paid for this.I knew in the back of my mind after doing all the correct diag that it could only be the ficm .They even wanted me to replace the starter motor.

Another new thing that was interesting at a meeting yesterday. There is a possibilty of FICM becoming internally servicable. They are thinking about getting the internal inverter board revamped and beefed up and allowing techs to dissassemble modules and replace boards. Doesn't that sound like a GREAT thing!!! Not sure if it will happen or not but if it does it will suck.

I would say it is about damn time! I've busted these things apart before, and it's really not much to it. The main DC-DC convertors are on a separate module within the box, and it simply plugs into the main board.

 

Personally, I would like to see more servicable modules. I had to put a PCM in a taurus the other day for an igntition primary circuit B open. $530 for the part! The owner nearly crapped himself! And for what, a faulty transistor? You know, I could have desoldered that switch and soldered in another one....

I've "rebuilt" a many of the ol ccrm's. The fuel pump relay output solder trace in the circuit board was bad about burning into, down in the hot states. I would jump the two points out with a piece of 16 gage wire and viola, a perfectly good module for friends or family or as a tester. Did the same thing for the old air bag monitors that would blow the internal fuse in an accident rendering the module useless. Installed a fuse holder and taped it to the outside making another known good tester. Posted Image

Thats exactly what I would use to do before I would install the new airbag monitor. Nothing worse than installing a brand new airbag monitor and having the internal fuse blow. Been there, done that Posted Image

 

If they want us to take apart FICMs, then I say bring it on. I can handle it. Posted Image

For a $700-800 part you think it last a little longer than that. Im replacing 1-2 ficms a week and we are slow...I imagine things will get worse once we start pushing 100*+ in the summer
