The FICM controls the fuel injectors on the 6.0L engine. It is responsible for stepping up the battery voltage to 48 volts, which is required to activate the injectors. The FICM works in conjunction with the Powertrain Control Module (PCM) to control fuel delivery to the engine. The module is mounted on the engine's valve cover, a high heat and vibration prone area.
The FICM has a high failure rate on the 6.0L engine, which may cause stalling or a no-start condition. OEM replacement modules come un-programmed and must be programmed by the installer prior to vehicle operation, a difficult and costly task for the independent repair facility. These FICM's are 100% torn down, upgraded, & full tested on GB's proprietary vehicle simulator. Once full tested the modules are pre-programmed with the appropriate vehicle software and are ready for installation and operation.
Three part numbers offer complete coverage for the F-Super Duty, E-Series, vans as well as the Excursion.
