The Transmission Scan Tool Data Definitions contain a brief description of manual transmission related parameters available on the scan tool. The list is in alphabetical order. A given parameter may appear in any one of the data lists. In some cases, the parameter appears more than once or in more than one data list in order to group certain related parameters together.

Clutch Pedal Switch: The scan tool displays APPLIED or RELEASED. The PCM monitors the clutch pedal switch input. If a low voltage is monitored, the PCM considers the clutch anticipate switch closed to ground, when the clutch pedal released. This is done to avoid a possible RPM flare caused by the sudden change in engine load.

Vehicle Speed: The scan tool displays 0-255 km/h (0-155 mph). The vehicle speed sensor signal is converted into miles per hour and kilometers per hour for display.
