Fuel Pump Driver Module (FPDM)

The FPDM is located in the LH rear of the luggage compartment. The module is attached to a bracket suspension turret and secured with two bolts.

The low pressure fuel pump (located in the fuel tank) operation is regulated by the FPDM which is controlled by a PWM signal, output by the ECM. The FPDM regulates the fuel flow and pressure output of the low pressure pump by controlling the fuel pump using a PWM output.

The FPDM is powered by a supply from the fuel pump relay in the BJB. The fuel pump relay is energized on opening the driver's door or when power mode 9 engine crank is initiated using the stop/start button. The FPDM supplies power to the fuel pump, and adjusts the power to control the speed of the fuel pump and thus the pressure and flow in the low pressure fuel delivery line.
