Fuel Pump Control Module
WARNING: This page is about a different car, the 2014 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
The fuel pump control module (FPCM) controls the discharging volume of the fuel pump by transmitting the FPCM control signals depending on driving conditions.
