Ford 6.0 Powerstroke Diesel FICM Removal and Diagnosis Instructional Video

[jeff1697]

Hey- Ron my ficm test 48 on thr meter but i noticed that the altinator doesn't seem to be]

working would this make any difference.

My truck is running similar to the one on the video

Let me add that when warm the FICM will show 48 volts no matter what I do. Running with all accesories on will be 48 volts. Even key on with the engine off and headlights on will show 48 volts. Do I have a problem?

[70donnybrooke]

I have a question for you. I recently got an EDGE insight. Let me first say that I have no starting issues and no driving issues. The last two cold starts I had an alarm go off on the EDGE. It is telling me low FICM voltage. I looked and thought I saw 37 volts. It was only quick and then I started driving and it went up to 45 then in about 15 seconds it was 48 volts. All the way to work I had 48 volts. When I started it at work it showed 41 volts that as soon as I started driving went up to 48.

Well I took my truck to the dealership. They told me my ficm, glow plug relay and my alternator is bad. They said to replace alternator first to see if it fixes my voltage for my ficm, then go from there.

[DieselTechRon]

@ctmiller6062 If it drops below 45 the alternator will not fix it. But if you replace it and the batteries and charging system has a fault, the new one will not last either.

Hey Ron, i have a 2004 f250 6.0L and i'm kinda of having the same problem. when i accelerate it seems like it's starving for fuel. It even idles a little rough. So I tested my ficm when its running and i get like 44 to 45 volts. I know it is suppose to be at 48 volts but I don't know if it's bad. The voltage seems to jump back and fourth. I thought it could be my HPOP, or fuel pump. If you have any ideas I would really appreciate your input. Thanks.

[DieselTechRon]

@ctmiller6062 Sorry for the late reply. 44-45 is bad but not bad enough to cause an obvios problem. Is that voltage while driving or idling? If that is idling then yes it will drop even more when you raise the rpms or work it and it may be your ficm. Does it clear up when warm? If so maybe you also have sticking injectors. It's not the HPOP. it can cause a lack of power but not misfire. it supplies all of the injectors and they are even high or low. Your ipr should never hit 85%

Good video.Very helpful.Thanks !

[DieselTechRon]

Respond to this video... I would need to know the colors but most likely it is for your trailer brake if you added one. The other end should be around your data link connector on the inside.

[DieselTechRon]

@JDBrown1966 Are you using any fluids? Esp coolant? does it smell like fuel? How much smoke and does it last the whole time it is running? any codes? If it is using water then it is probably and egr cooler. If not it may be as simple as a glow plug not warming up the cylinder enough it it clears up in a few minutes or it can be an egr valve or injector. Need more info

Thanks Ron, Just getting in on the diesel repair side and learning all i can. Your videos are clear and on point. Keep them coming. Would love some driveability videos.

[DieselTechRon]

@ldcater1 I can do that. Like what type of symptoms should I cover? What would be a good title for people can find it? Let me know what you find the most common and I'll address it.

[JIMRSX]

Thank you Ron, your video let me do this procedure without any drama.

[DieselTechRon]
