Fuel Pump Driver Module (FPDM)

FPDM receives a duty cycle signal from the PCM and controls fuel pump operation. This results in variable speed fuel pump operation. FPDM uses the fuel pump monitor circuit to send diagnostic information to the PCM.

NOTE: Components are grouped into 2 categories. The first category covers INPUT DEVICES, which control or produce voltage signals monitored by the control unit. The second category covers OUTPUT SIGNALS, covering components controlled by the PCM.
