Scan Tool Output Control | Additional Menu Selection(s) | Description | ||||||
|---|---|---|---|---|---|---|---|---|
APP Learn | Engine Output Controls/Throttle Control System | Allows the throttle actuator control (TAC) module to relearn the acceleration pedal position (APP) sensor released minimum position. An APP learn may be necessary after a fault has been corrected that caused the TAC module to learn an incorrect low position. | ||||||
-- | Engine Output Controls/Crankshaft Position Variation Learn | Enables the powertrain control module (PCM) to learn the variations in the crankshaft position (CKP) system. The PCM will learn the variations once the following conditions are met:
The PCM learns the variation values during deceleration from fuel cut-off. | ||||||
Cylinder Power Balance | Fuel System | Enables/Disables a cylinder by turning OFF the fuel injector to the cylinder. The fuel injector is normally enabled. The PCM disables the fuel injector when the following conditions are met:
When DISABLE is selected, the PCM turns the injector OFF for 30 seconds. During this period, the engine operates with a misfire. | ||||||
EGR Solenoid | Engine Output Controls | Activates exhaust gas recirculation (EGR) solenoid in 10 percent increments from 0-100 percent for a maximum of 15 seconds. | ||||||
Engine Speed Control | TAC System | Activates idle speed override in 25 RPM to 100 RPM increments, from 0 RPM to 1500 RPM. | ||||||
EVAP Purge Solenoid | Engine Output Controls/EVAP System | Activates the purge solenoid in 10 percent increments from 0-100 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 fuel tank pressure sensor exceeds 19 mm Hg (10 in H2O). | ||||||
EVAP Purge/Seal | Engine Output Controls/EVAP System | Simultaneously activates purge solenoid in 10 percent increments from 0-100 percent and the vent solenoid. Device control will be aborted and inhibited if the FTP sensor exceeds 19 mm Hg (10 in H2O). | ||||||
Fuel Injector Balance Test | 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 Pump | Engine Output Controls | Activates the fuel pump relay for 2 seconds. | ||||||
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/Dash Lamps | Activates the malfunction indicator lamp (MIL). The MIL will remain illuminated until cancelled by the scan tool. | ||||||
-- | Engine Output Controls/Misfire Graphic | Graphs the accumulated misfires occurring in each cylinder. The scan tool allows for a reset of the misfire graph. | ||||||
Throttle Position | Engine Output Controls/Throttle Control System | Activates the throttle plate in 10 percent increments from 0-100 percent. The output device control is disabled if the manifold absolute pressure (MAP) is less than 60 kPa. |
