Output State Control (OSC) Mode: Description

Output state control (OSC) allows an off-board diagnostic scan tool direct control of specific transaxle components or functions. OSC allows the technician to control the main functions or components of the transaxle to help the technician more quickly and easily diagnose the transaxle. For example, OSC may be used to change gears or remain in a specific gear. OSC may be used to control the operation of the torque converter clutch (TCC) to engage or disengage, or to keep the converter clutch from engaging at all. OSC may also 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.
