Output State Control (OSC) Mode: Description
WARNING: This page is about a different car, the 2005 Mercury Sable and 2005 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
Output state control (OSC) on the NGS or WDS diagnostic tool allows the technician to easily and quickly control the main functions and components of the 4F50N transmission. OSC is used to help test the electrical, hydraulic or mechanical concerns related to the transmission. The NGS or WDS also provides PID information, along with the OSC functions, to accurately diagnose the transmission. For example, OSC allows the technician to shift the transmission, engage the converter clutch, command line pressure or turn a solenoid off and on.
