#### Engine Control Module Scan Tool Output Control

Scan Tool Output Control | Additional Menu Selection(s) | Description
--- | --- | ---
A/C Relay | Cooling/HVAC Data | Air Conditioning Compressor Clutch Enable; Air Conditioning Compressor Clutch ON
Aux. Vacuum Pump | Induction Data | Brake Boost Pump Control
CMP Actuator Data System | Exh. CMP Actuator Sol. | Exhaust Cam Phase Solenoid Bank 1 Enable; Exhaust Cam Phase Solenoid ON
CMP Actuator System | Exhaust CMP Actuator Bank 1 | This function controls the exhaust camshaft position (CMP) actuator. The normal commanded state is 0 degrees. The system will INCREASE or DECREASE the exhaust camshaft timing by changing the duty cycle of the actuator in 5-degree increments up to 50 degrees. This also affects Desired Exh. CMP Angle.
CMP Actuator System | Int. CMP Actuator Sol. | Intake Cam Phase Solenoid Bank 1 Enable; Intake Cam Phase Solenoid Bank 1 ON
CMP Actuator System | Intake CMP Actuator Bank 1 | This function controls the intake CMP actuator. The normal commanded state is 0 degrees. The system will INCREASE or DECREASE the intake camshaft timing by changing the duty cycle of the actuator in 5 degree increments up to 40 degrees. This also affects Desired Int. CMP Angle.
Cooling Fan | Cooling/HVAC Data | Cooling Fan Speed Enable; Cooling Fan Speed
Cylinder Power Balance | Misfire Data | Fuel Injector Enable; Fuel Injector ON
Engine Speed Control | TAC System | Activates the throttle activation control (TAC) system to change engine RPM. The normal commanded state is None. To enable the RPM control, all instruction on the scan tool must be completed. The system will increase or decrease the RPM within a range of 400-2,200 RPM. The set step value changes the RPM by increments of 25 RPM, 100 RPM, and 500 RPM. The system remains in the commanded state until cancelled by the scan tool.
EVAP System | EVAP Purge Solenoid | Activates the purge solenoid in 10 percent increments from 0 to 100 percent. The device control will be aborted and inhibited if the fuel tank pressure (FTP) sensor exceeds -27 mm Hg (-14 in H2O).
EVAP System | EVAP Vent Solenoid | Activates the vent solenoid. The device control will be aborted and inhibited if the FTP sensor exceeds -27 mm Hg (-14 in H2O).
EVAP System | EVAP Purge/Seal | Simultaneously activates the purge solenoid in 10 percent increments from 0 to 100 percent and the vent solenoid. The device control will be aborted and inhibited if the FTP sensor exceeds -27 mm Hg (-14 in H2O).
EVAP Test | EVAP Data | EVAP Service Test Trigger
Fuel Pump | Fuel Pump Relay | Activates the fuel pump relay for 2 seconds. Also turns fuel pump ON and OFF while engine is running.
Fuel System | Fuel Pressure Control | High Pressure Fuel Supply System Control - Demanded High Pressure
Fuel System | Fuel Pressure Control | High Pressure Fuel Supply System Control - MSV Control At Engine Running "High Pressure Test"
Fuel Trim Enable | Fuel System | Disables the PCMs ability to learn new fuel trim parameters. The commanded states are NONE, ENABLED, DISABLED. The normal commanded state is NONE. The system remains in the commanded state until cancelled by the scan tool.
Fuel Trim Reset | Fuel System | Activates the reset of fuel trim data in all fuel trim cells.
GEN L-Terminal | Electrical/Theft Data | Generator L-Terminal Enable; Generator L-Terminal ON
Idle Learn Reset | TAC Data | Idle Adapts Reset Trigger
Loop Status | Fuel Trim Data | Controls the system loop status. The commanded states include NONE, OPEN, or CLOSED. The normal commanded state is NONE. When commanded OPEN or CLOSED, the system remains in the commanded state until cancelled by the scan tool.
Malfunction Indicator Lamp | Engine Data | Malfunction Indicator Lamp Enable; Malfunction Indicator Lamp ON
Oil Life Reset | IPC Data | Engine Oil Life Remaining
Spark Control | Idle Spark | Enables or disables idle spark command. When commanded ON, the idle spark will be controlled to 13 degrees before top dead center. The normal commanded state is OFF.
Special Durations | Misfire Graphic | Graphs the accumulated misfires occurring in each cylinder. The scan tool allows for a reset of the misfire graph.
Starter Relay Control | Electrical/Theft Data | Starter Relay Enable Starter Relay ON
TC Bypass Solenoid | Induction Data | TC Bypass Solenoid Command ON/OFF
TC Wastegate Solenoid | Induction Data | Wastegate Solenoid Command 0-100%
Throttle Position | TAC System | Operates TAC motor in 10 percent increments to open or close the throttle blade. The test operates during key ON, engine OFF.
