P0611 code after 58V ficm install

[ULM2008]

Is this because whoever worked on it didnt program it to show the computer 48V? It shows constant 50V on my CS. I tried to clear it wont go away.

Who did the mod? Contact them and see what they think.

Any modded FICM will throw a soft code for the FICM. Edge units can't read more than 50V for those too, so you'll never see the 58 on that...

There is nothing to "program" to show anything, it's just hardware updates that change it to 58V. You can test it with a multi-meter to verify it's 58V though.

All 58v units will show P0611.

The PCM is designed to see nothing above 50v

I have seen that code on mine. No light though.

Thanks bud! I put a lot of money in this truck because I LOVE it! I couldnt do it without the info gained here thats for damm sure!

PS,
The 58V ficm from vivian is superb! I did not plug the truck in last night for the first time in 2 weeks. The temps dipped in to the high 20s last night. This morning was the first test. Starts up like new

Good to hear! Yea, my trucks sweet spot is 16* Anything colder she gets really pis$ed starting without being plugged in.

With the 58v it seems to do more a SNAP alive than a groggy lope. I noticed mine snaps alive and others just seem to fire.

It was 28* degrees here last night by NO means nessisary to plug in but I did thow the timer on and have a warm truck this am! Something seems a lot better about 80* oil compaired to 28* oil.
