Things to check if having issues on F150/F250 FICM:
-
Check the fuses and clean connectors, ensure its properly seated.
-
If the alternator or battery is bad it will drain the FICM and may possibly make it bad again, to ensure this doesn’t happen make sure you’re charging system is getting at least 12.5 volts before it even gets the FICM. Low batteries may cause this, and you can take your alternator and get it tested locally.
-
The FICM should be getting 48v as this is the proper voltage required if it drops lower than that then again check the former steps to make sure that there’s nothing in the truck causing voltage fluctuations.
