ISSUE
Some 2003-2007 F-Super Duty, 2003-2005 Excursion and 2004-2010 E-Series vehicles equipped with a 6.0L engine may exhibit a runs rough, lacks
power, hard start, no start concern with or without diagnostic trouble code (DTC) P0611 code or various injector circuit codes. This concern may be
caused by a DC-DC converter located in one half of the Fuel Injector Control Module (FICM) or by the main circuit board in the other half of the FICM.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
FICM Information:
The FICM contains two major internal components, the main circuit board and a DC-DC converter. The DC-DC converter is the device that amplifies
battery voltage to 48 volts to operate the injectors.
Low FICM supply voltage results in increased FICM operating loads, potentially damaging or shortening the life of the FICM.
For contribution codes without circuit codes, go to Powertrain Controls/Emissions Diagnosis (PC/ED) pinpoint test P. Do not continue with this
procedure.
1. Connect Integrated Diagnostic System (IDS) scan tool and confirm battery voltage is greater then 11.5 volts key on engine off (KOEO).
a. If battery voltage is less then 11.5 volts KOEO, do not continue with this article. Refer to Workshop Manual (WSM), Section 414-00.
b. If battery voltage is 11.5 volts KOEO or higher, continue to Step 2.
2. Remove the FICM relay.
3. Perform a programmable module installation (PMI) on the FICM to correct possible corrupt FICM memory.
a. IDS scan tool software must be at release level 65.18, or higher.
b. Select module programming on the IDS menu screen.
c. Select PMI and click on the tick button at the bottom right corner of the screen.
d. Follow the directions on the screen until it states to install the new module. At this point, click on the tick button again and continue to follow the
on screen directions to complete the PMI procedure.
4.
Reinstall the FICM relay.
5.
Monitor the FICM_M power parameter identification (PID) per the following instructions:
