FICM relays are an oft-neglected afterthought, but provide the critical transfer of amperage from your charging system to the FICM. This relay is located under the hood on the drivers side fender well in the fuse panel next to the firewall.
How do you know if you have a bad FICM?
A failing FICM can cause all sorts of problems, but one of the most common symptoms is an engine that is hard to get started, especially when the engine is cold or has sat overnight. Another symptom commonly seen is the engine is running rough or misfiring all of the time, or after the engine is warmed up.11 Jan 2021
What are the symptoms of a bad FICM on a 6.0 Powerstroke?
What a Failing FICM Looks and Sounds Like. When you aren't getting 48-volts to the injector coils you get: hard starts, rough idle, loss of power, poor drivability, and excessive smoke out the tailpipe—and in cold weather each of those symptoms will be amplified.26 Mar 2021
What are the symptoms of a bad FICM relay?
A weak or failing FICM will contribute to hard start, rough idle, and/or intermittent rough running conditions. While engine heat and vibration contributes to FICM failures, the number one cause (arguably) is a low battery voltage condition.
What is FICM main power?
On Ford 6.0L Powerstroke engines, the purpose of the Fuel Injection Control Module (FICM) is to supply 48 volts to the two solenoids that control pressurized oil flow to the fuel injector. The FICM uses a series of internal capacitors to turn the vehicle voltage (12-14.5 volts) into the 48-volt supply.
Where is the FICM fuse located?
Mine is just aft of the driver's side battery, down towards the inner fender lining. There are two aux fuse/relay panels underhood on the driver's side.23 Dec 2010
Will a bad FICM throw a code?
Registered. The ficm are vin specific, but they will run if installed. It will just throw a code that you will only be able to read with the ford scanner.8 Jun 2010

What does a upgraded FICM do?
Stock non-modified FICM's will be 48 volts. Upgraded FICM's are offered at a 58 volt. Running a 58 volt FICM will help with pedal response, hold the injector spool valve further open, increase horsepower(~30hp) and better cold climate starting.27 Sept 2019
