Automatic Transmission/Transaxle: Description and Operation

The on-board diagnosis system integrated within the transmission control module on-board diagnosis malfunctions of the main sensor (input) and solenoid valves (output) as well as the transmission control module itself. Malfunctions or intermittent malfunctions are memorized in the transmission control module to later be output as diagnostic trouble codes. The New Generation Star (NGS) tester can be used to retrieve these diagnostic trouble codes. The NGS indicates a malfunction by displaying a diagnostic trouble code.
