Output State Control (OSC) Mode: Notes

NOTE: Retrieve continuous codes and carry out a KOEO & KOER On-Demand Self Test before using output state control (OSC). Any diagnostic trouble codes (DTCs) related to the transmission range (TR) sensor, output shaft speed (OSS) sensor or the vehicle speed sensor (VSS) must be fixed first or the powertrain control module (PCM) will not allow the OSC to operate.

OSC on the scan tool allows the technician to easily and quickly control the main functions and components of this 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, or command line pressure or turn a solenoid off and on. OSC has 2 menus for operation, the BENCH mode and the DRIVE mode.
