Fuel Injector Control Module (FICM)
WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2005 Mercury Sable, 2005 Mercury Mountaineer, 2005 Mercury Monterey, 2005 Mercury Montego, and 2005 Mercury Mariner. However, it is still accessible from the selected car via links, so may be relevant.
The FICM receives input from the PCM. Based on the information received and programmed into its memory, the FICM generates output signals to control the injector solenoids. The FICM contains a set of drivers for both the primary (forward) and secondary (rearward) fuel injectors. Fuel injector driver signals from the powertrain control module (PCM) are used to control both sets of output drivers in the FICM. Based on the fuel selector switch input, the FICM controls either the primary or both the primary and secondary fuel injectors.
