Fuel Pump Driver Module

2004 Ford Pickup F350 Super Duty, 4D Pickup, 6.8 S, RWD, AutomaticSECTION Fuel Pump Driver Module
NOTE: For the Thunderbird and LS6/LS8, the FPDM functions are incorporated in the Rear Electronic Module (REM). Fuel pump operation is the same as applications using the stand-alone FPDM. The REM will, however, communicate diagnostic information through the communication link instead of using a fuel pump monitor (FPM) circuit.

The fuel pump driver module (FPDM) receives a duty cycle signal from the PCM and controls the fuel pump operation in relation to this duty cycle. This results in variable speed fuel pump operation. The FPDM sends diagnostic information to the PCM on the fuel pump monitor circuit. For additional information, refer to PCM OUTPUTS , FUEL PUMP  and PCM INPUTS , FUEL PUMP MONITOR .
