| 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")

Inspection 1. Turn the ignition switch OFF. 2. Disconnect the mode control actuator connector. 3. Verify that the mode control actuator operates to the defrost mode when connecting 12V to terminal 3 and grounding terminal 4. Verify that the mode control actuator operates to the vent mode when connected in reverse.
