Scan Tool Output Controls
Powertrain Control Module Scan Tool Output Control
| Scan Tool Output Control | Additional Menu Selection(s) | Description |
|---|---|---|
| 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 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). |
| 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. |
| - | Engine Output Controls/Fuel Pump | Activates the fuel pump relay for 2 seconds. Also turns fuel pump ON and OFF while engine is running. |
| 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. |
| 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. |
| Malfunction Indicator Lamp | Engine Output Controls | Activates the malfunction indicator lamp (MIL). The MIL will remain illuminated 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 Bank | Engine Output Controls/Heated Oxygen Sensor | 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. |
| 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. |
| APP Learn | APP Learn | This procedure allows the TAC system to re-learn the minimum accelerator pedal position in the even of the bracket and rod assembly replacement. |
| Cam Phaser | Engine Output Controls/CMP Actuator System/CMP Actuator | Activates the CMP Actuator. 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. |
| CMP Actuator Solenoid | Engine Output Controls/CMP Actuator System/CMP Actuator Solenoid | Activates the CMP Actuator. 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. |
| Engine Output Controls/Engine Controls Ignition Relay | Activates the Engine Controls Ignition Relay. 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. | |
| Engine Output Controls/IMT Valve | Activates the IMT Valve. 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. | |
| Spark Retard | Engine Output Controls/Spark Control | |
| Idle Spark | Engine Output Controls/Spark Control |
