FICM code

[olgoat]

I scanned my truck for codes today and found P0264, P0267, P0273, P0282 and P0611. The P0611 is the FCIM and the others are low injector voltage on different injectors. The P0611 has been around for a couple of months but the others just poped up. The truck seems to run fine. I've checked the FICM voltage and it's 48v, that was a couple of weeks ago. I run a SCT tuner on an ecno tune. My question is what is the likelihood of re-flowing the solder in the FICM fixing the problem. I'd like to not spend the money for a new FICM if I don't have to.

Thank in advance for the help,
Lonnie

If your truck is still running fine and your FICM is testing out okay I don't see why you would need to do anything at this point?

Did these codes pop up after you last checked the FICM voltage? If so I'd verify that the FICM is still hitting 48v. If not, honestly I'd just clear the codes and keep trucking.

But then again, if you're handy with a soldering iron and feel like tinkering with it go ahead haha.

Well I went ahead a took the FICM apart to do the repair that I've found on this site and what I found was a resistor that was held on to the circuit board by just the amber goo. Once I removed the amber goo the resistor fell off of the circuit board. I re-soldered the resistor and all the other points on the board and the DTC codes have not come back. I've had a slight rough idle for about a year, I just thought it was an injector. The rough idle is now gone. Fuel mileage is up a little too.
I would like to say thank you to who ever posted the instructions for repairing the FICM, you saved me a ton of money.

Just a heads up, I think that amber goo is to help against vibration.

I removed the amber goo from just the screws and the resistors that need to be reflowed, I left it around all the large parts.
