Speedometer

SPEEDOMETER
The speedometer is a road indicator. The vehicle speed sensor (VSS) is a permanent magnet generator which is located on the transaxle. The VSS sends an input to the PCM whenever the transaxle differential carrier turns. The PCM then buffers the VSS signal. The PCM transmits the VSS signal to the following components at 4000 pulses/mile through CKT 817:
^ The instrument cluster
^ The cruise control module
^ The radio (uplevel)
The instrument cluster uses the input in order to indicate the vehicle speed on the speedometer.
