NEED help please code P0611

[studded]

Today my truck just doesnt like me. Started it this morning and saw low brake fluid level so i thought thats no problem plugged in my sct to see if there was any codes and i saw P0611 and P1000. Ive looked up the P0611 and everyone said this leads to FICM failure how can i test this? Love my truck but i guess it doesnt love me =(.

I have both of those also. I was told the 611 was because I installed a 58V ficm. And the 1000 I think is a ???? Ever since I installed my sct I think.

p0611 pretty much means your ficm output is below a set voltage. It can be caused by weak batteries but usually it just means your FICM is on it's way out.

disconnected battery's and one came back at 12.1 the other 12.2. Is this to low? also check voltage when i start it , drops to 11.4 then slowly climbs to 13.3. left it running for 10 min stayed at 13.3, seems low for a running diesel?

went to advanced to load test battery's also but there machine was broken going to a different one tomorrow to confirm the battery's.
