Output State Control (OSC) Mode: Description

Output state control (OSC) on the scan 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 scan tool 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.
