Output State Control (OSC) Mode: Description

Output state control allows a diagnostic scan tool direct control of specific transmission components or functions. Output state control allows the technician to control the main functions or components of the transmission to help the technician diagnose the transmission quickly and easily. For example, output state control may be used to change gears or remain in a specific gear. Output state control may be used to control the operation of the TCC to engage or disengage, or to keep the converter clutch from engaging at all. Output state control may be used to help carry out solenoid electrical pinpoint tests by turning a solenoid off or on by controlling the actual current to the VFS solenoid.
