The Fuel Pump Driver Module (FPDM) is located behind the right second row seat. The FPDM module is attached to a bracket and secured by 2 nuts to the rear underfloor reinforcement panel.

The fuel pump operation is regulated by the FPDM which is controlled by the Powertrain Control Module (PCM). The FPDM regulates the flow and pressure supplied by controlling the operation of the fuel pump using a Pulse Width Modulation (PWM) output.

The FPDM is powered by a supply from the fuel pump relay in the Rear Junction Box (RJB). The FPDM supplies power to the fuel pump, and adjusts the power to control the speed of the fuel pump. The FPDM also controls pressure and flow in the fuel delivery line.

The following conditions will energize the fuel pump relay:

Opening the driver door.
Operating the ignition switch.
Operating the ignition switch with applied brakes - Engine crank.

The FPDM supplies power to the fuel pump through hardwired connections. The FPDM adjusts the power to control the speed of the fuel pump, thus the fuel pressure and flow in the fuel delivery line.
