RailP_Max_Thresh
Tip Strip: Rail pressure maximum threshold which causes a critical fault and shuts down associated PFI LSX
channels
Units: bar
Detail: An upper threshold for rail pressure which defines a critical fault level that could potentially damage
the fuel system. If this threshold is exceeded, the low-side channels controlling the IMV and HPV turn off until
the RailPFault error has been cleared.
RailP_Fault
Tip Strip: Indicates the rail pressure fault status
Detail: Indicates that the rail pressure has exceeded the value specified in RailP_Max_Thresh. This fault
must be manually cleared by
BattV
Tip Strip: Battery voltage measured by the DI Driver module
Units: V
Detail: Battery voltage measured by the DI Driver module. Battery voltage is used to calculate, in real time,
the current supplied to the IMV and HPV solenoids, to ensure that the current does not exceed 3A.
RailP_Setpoint
Tip Strip: Rail pressure setpoint to PID controller
Units: bar
Detail: Desired rail pressure setpoint.
Clear RailP Fault.
