Selection(s)
This function controls the evaporative emission (EVAP) purge
solenoid valve. The normal commanded state is NONE. The
system will increase or decrease the amount of purge by changing
the duty cycle of the purge valve in 10 percent increments within a
range of 0-100 percent. The system remains in the commanded
state until cancelled by the scan tool or the fuel tank pressure (FTP)
sensor exceeds −24 mm Hg (−12 inch H20).
This function activates both the EVAP purge solenoid valve and
EVAP vent solenoid to seal the EVAP system. When activated, the
purge valve is commanded to 0 percent and the vent valve is
commanded ON, Not-venting. The normal commanded state for
both solenoids is None. Both of the solenoids remain in the
commanded state until cancelled by the scan tool or the FTP
sensor exceeds −24 mm Hg (−12 inch H20).
This function controls the EVAP vent solenoid. The normal
commanded state is NONE. When commanded ON, the vent valve
switches to Not-venting. The system remains in the commanded
state unless one of the following conditions occur:
• Cancelled by the scan tool
• The EVAP canister purge solenoid is more than 0 percent, and
the FTP sensor exceeds −24 mm Hg (−12 inch H20).
This function enables the fuel injector in order to verify the correct
fuel injector flow. The ECM will pulse the selected fuel injector when
the following conditions are met:
• All instruction on the scan tool is complete.
• A fuel injector is selected.
• The ignition is ON with the engine OFF.
The selected fuel injector can only be flowed/pulsed once per
ignition cycle.
This function controls the fuel pump relay. The normal commanded
state is NONE. The scan tool initiates the test when the following
conditions are met:
• There are no vehicle speed sensor DTCs set.
• The vehicle speed is 0 km/h (0 mph).
When commanded ON/OFF, the engine control module (ECM)
turns the fuel pump relay ON/OFF. If the engine is running and the
fuel pump relay is commanded OFF, the engine will stall. The
system remains in the commanded state for about 2 seconds or
until cancelled by the scan tool or the ECM detects a vehicle speed.
