Special Tool(s)
| Worldwide Diagnostic System (WDS) Vehicle Communication Module (VCM) with appropriate adapters, or equivalent diagnostic tool |
Output State Control (OSC) using the NGS or WDS diagnostic 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 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, or engage the converter clutch, or command line pressure or turn a solenoid off and on.
