| Description |

| Operation |

| 1. |
The ECM receives the target fuel pressure signal through CAN communication with the FPCM. |
| 2. |
The FPS applies the current low fuel pressure value to the FPCM. |
| 3. |
The FPCM controls the 3-phase duty function of the low pressure fuel pump. |
| 4. |
The FPS applies the current low fuel pressure value to the FPCM. |
| 5. |
It controls the low pressure fuel pump based on the RPM and vehicle load to provide a consistent flow rate. |
Removal 1. Turn the ignition switch OFF and disconnect the battery negative (-) cable. 2. Release the residual pressure in fuel line. (Refer to Fuel Delivery System -"Release Residual Pressure in Fuel Line")
