Scan Tool Output Controls
Powertrain 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 |
| Compression Test | TP Indicated Angle | Compression Service Bay Test Device Control |
| 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 Purge Solenoid | Engine Output Controls/EVAP System | 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 19 mm Hg (10 in H2O). |
| EVAP Test | EVAP Data | EVAP Service Test Trigger |
| EVAP Vent Solenoid | Engine Output Controls/EVAP System | Activates the vent solenoid. The device control will be aborted and inhibited if the FTP sensor exceeds 19 mm Hg (10 in H2O). |
| EVAP Purge/Seal | Engine Output Controls/EVAP System | 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 19 mm Hg (10 in H2O). |
| Exh. CMP Actuator Sol. | CMP Actuator Data | Exhaust Cam Phase Solenoid Bank 1 Enable; Exhaust Cam Phase Solenoid Bank 1 ON |
| Exhaust CMP Actuator | CMP Actuator System | 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 Bank 1 and Bank 2. |
| Fuel Injector Balance | Fuel System | Enables the fuel injector in order to verify proper fuel injector flow. The PCM will pulse the selected injector when the following conditions are met:
The selected fuel injector can only be flowed/pulsed once per ignition cycle. |
| Fuel Pressure Control | Fuel System Data | High Pressure Fuel Supply System Control - Demanded High Pressure |
| Fuel Pressure Control | Fuel System Data | High Pressure Fuel Supply System Control - MSV Control At Engine Running "High Pressure Test" |
| Fuel Pump | Engine Output Controls | Activates the fuel pump relay for 2 seconds. Also turns fuel pump ON and OFF while engine is running. |
| Fuel Pump Relay | Engine Data | Fuel Pump Enable; Fuel Pump Duty Cycle |
| Fuel System High Pressure Reduction | Fuel System Data | SIDI High Pressure Fuel Supply System Control - High Pressure Reduction |
| 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 |
| HO2S Heater Sensor 1 | HO2S Data | Oxygen Sensor Heater Bank 1 Sensor 1 Enable; Oxygen Sensor Heater Bank 1 Sensor 1 Duty Cycle |
| HO2S Heater Sensor 2 | HO2S Data | Oxygen Sensor Heater Bank 1 Sensor 2 Enable; Oxygen Sensor Heater Bank 1 Sensor 2 Duty Cycle |
| Idle Learn Reset | TAC Data | Idle Adapts Reset Trigger |
| Idle Spark | Engine Output Controls/Spark Control | 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. |
| Int. CMP Actuator Sol. | CMP Actuator Data | Intake Cam Phase Solenoid Bank 1 Enable; Intake Cam Phase Solenoid Bank 1 ON |
| Intake CMP Actuator | CMP Actuator System | 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 Bank 1 and Bank 2. |
| Loop Status | Engine Output Controls | 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. |
| - | Misfire Graphic | Graphs the accumulated misfires occurring in each cylinder. The scan tool allows for a reset of the misfire graph. |
| HO2S Heater Driver | Engine Output Controls | Activates the heated oxygen sensor (HO2S) heater. The commanded states include NONE, ON, and OFF. The normal commanded state is NONE. The system remains in the commanded state until cancelled by the tool. |
| Malfunction Indicator Lamp | Engine Data | Malfunction Indicator Lamp Enable; Malfunction Indicator Lamp ON |
| Oil Life Reset | IPC Data | Engine Oil Life Remaining |
| Starter Relay | Electrical/Theft Data | $20 - Starter Relay Enable; Starter Relay Enable Starter Relay ON |
| TC Bypass Solenoid | Induction Data | Turbo Overrun Air Valve Control |
| TC Wastegate Solenoid | Induction Data | Turbo Wastegate Control |
| 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. |
