FICM !? Help me !

[rado]

FVP ~ n. 7V n.10 sek but then normal 12V
FLP ~ n. 11.5V-13.5V always
FMP ~ 47.5V-48.5V always

Normal or FICM broken ?

What's the FVP mean? The rest looks perfect

[rado]

FVP = FICM Vehicle Power (V)

Scangauge II show FVP

Is that normal 7V at first ?

You have 7v before cranking? In that case I'd say that you need to replace your batteries (both) before you smoke the FICM

But Battery`s 11.5v-12.5v ?

Why FVP only 7v ?

I can't find any mention of the FVP causing any issues. The MP is the one to watch. I'm thinking it may drop to your values when the key is turned on, and the injectors cycle, the vac pump comes on etc, before starting truck, and then returns to 12v+ after running . I wouldn't sweat it

There's no link for the second video. It def doesn't run well, cold. I'm gonna see if someone else can chime in. I have never heard of the FVP causing a driveability issue

Definetely


The FVP looks correct after the new batteries . Is it still running rough? I noticed that the EOT was at 116* this time instead of 70* in the first video. Was the truck warmed up at that time?

The ICP seemed a bit low to me. I know the PCM needs to see at least 500psi to start, but I'm not positive of what running/at operating temp pressure should be . I PM'd a guy that should be able to help you
