Operation |
1. |
The ECM provides target fuel pressure information to the FPCM via CAN network. |
2. |
The FPS provides the FPCM with actual pressure information of
the low pressure fuel line between the low and high pressure fuel
pumps, and the FPCM forwards the information to the ECM.Also, the FPCM
diagnoses faults in the FPCM, fuel pump motor and FPS and then provides
the diagnosis information to the ECM. |
3. |
The FPCM compares the actual fuel pressure information
measured by the FPS with the target fuel pressure information provided
by the ECM and controls the voltage that is provided to the low pressure
fuel pump motor.The FPCM keeps regulating fuel flow rate by controlling
the low pressure fuel pump, depending on engine speed (rpm) and vehicle
loads. |
