Fuel Pump Driver Module Applications & Applications With Fuel Pump Functions Incorporated In Rear Electronic Module)
WARNING: This page is about a different variant/trim than selected.
NOTE:
On LS and Thunderbird, FPDM functions are incorporated in Rear Electronic Module (REM). Fuel pump operation is same as applications using stand-alone FPDM. REM will communicate diagnostic information through Standard Corporate Protocol (SCP) BUS (+) and BUS (-) circuits, instead of using a Fuel Pump Monitor (FPM) circuit.
Fuel Pump (FP) signal is a duty cycle command sent from PCM to Fuel Pump Driver Module (FPDM). See Fig 1. FPDM uses FP command to operate fuel pump at speed requested by PCM or to turn pump off.
