SYSTEM DESCRIPTIONThe fuel pump control module (FPCM) controls the discharging volume of the fuel pump by the FPCM control signals (Low/Mid/Hi) depending on driving conditions.
| Conditions | Amount of fuel flow | Supplied voltage |
| Low | Approximately 8.5 V |
| high | Battery voltage (11 - 14 V) |
| Except the above | mid | Approximately 10 V |
