Vehicle Speed

The value indicates vehicle speed. The Transmission Control Module (TCM) receives a signal from the transmission speed sensor, which is actuated by toothed pulse gear and uses the signal to calculate vehicle speed. The speed sensor is a so-called active sensor. The signal oscillates between a peak and a valley value. The Transmission Control Module (TCM) calculates speed, which is in direct proportion to the frequency.

Measurement range: 0 - 655 km/h.
