IMV_NomResistance
Tip Strip: Nominal resistance of IMV solenoid
Units: Ohms
Detail: Nominal resistance of the IMV solenoid. This value is used to calculate the maximum final duty cycle
allowed to the IMV. It is important to measure this resistance /-0.5 ohms
IMV_Current
Tip Strip: Estimated current to IMV based on battery voltage and nominal solenoid resistance
Units: A
Detail: An estimate of the current flowing through the IMV based on the duty cycle, battery voltage, and the
nominal resistance of the valve.
HPV_Enable
Tip Strip: Enables PWM control of HPV
Detail: Enables the final PWM parameters to the lowside channels configured for HPV via the
window.
HPV_LSChanAsn
Tip Strip: Indicates the PFI Driver lowside channels assigned to drive the HPV. The channel assignment is
window.
HPV_Freq
Tip Strip: Operating Frequency of HPV PWM command
Units: Hz
Detail: Frequency of the PWM signal to the HPV solenoid.
