Sounds like perfect timing,

way to go! usually mine breaks 3,000 after the warranty expires.
|
FICM's are getting to be fairly commonplace failures, especially in hotter climates.
|
I'm in hot ass TX. And My warranty is out. I wonder if it would help, if any at all, to Install an Electric fan on top of the FICM to help it extract heat a little faster? I would think so since it already has heat sinks to put a fan on.

I've never really thought about it, but I wouldn't think it would help a great deal, since the case isn't very efficient at removing heat.
http://i291.photobucket.com/albums/l...09_0900_00.jpg The deal on the right is the transformer assemblies used to step the 12v up to 48v required by the injectors, and this is the part that fails. This is located at the front of the FICM, on the top, this is I would imagine where most of the heat is generated. I am going to do a little experimenting with remote locating these if I can find a truck suitable and willing to test it out locally to me. If you took those transformers out, an put them somewhere good and dry, that lots of cool air could flow over 'em, there's no reason that the longevity should suffer. The only thing that worries me is running 4 wires running 48v with the potential of 200v flyback voltage anywhere other than RIGHT WHERE IT IS, you know? It transfers voltage from those transformers through a screw and a steel terminal, no wiring involved - it drops little or no voltage across this connection - whereas through several feet of wire, there's likely some voltage loss. (The four posts sticking up in the circuit board in the middle, near the top.) :humm: I'll experiment with this and get back to you on it. Edit: little better view of the transformer dealies: http://i291.photobucket.com/albums/l...09_0859_01.jpg |
My truck seems to be running fine but the trouble code keeps coming back..:humm:After I have driven the truck in performance for a little while it says no dtc's detected..not sure why it keeps doing this?I also get a pc1000 obd 2 incomplete testing?

P1000 is what comes up when codes are cleared and all the monitors haven't run yet.
I would get a scanner and monitor FICM_VPWR, FICM_LPWR, and FICM_MPWR. If the LPWR pid isn't 48v KOEO and KOER, the FICM is packing it's bags to leave town on you, and likely in the middle of nowhere, which is, of course where all failures happen that prevent the truck from being drivable. :D |
there was supposed to be a service kit available for the transformers but they have not been made available yet to my knowledge.
i am hanging onto a few retail exchanges from the dealer just in case |

They'll probably screw it up like the CHRA and turbo. The parts to rebuild the turbo used to cost more than a complete turbo? Someone was thinkin. :w2: |
Mine just went to the stealership yesterday for this same thing, there is a TSB for the 04 6.0 but my FICM will not take the update so its fried and they cost $863 installed at the dealer.. Oh BTW im new here so Hi and thks for the good info..
