Fuel Pump Driver Module (FPDM)
FPDM interfaces with the PCM to control fuel pump operation. By controlling fuel pump operation, noise and the amount of hot fuel returned to the fuel tank is minimized. If FPDM or system fail self-test, DTC P1230, P1233, P1234, P1235 P1236, P1237 or P1238 may be set in PCM memory.
