Speedometer

The IPC displays the vehicle speed based on the information from the vehicle speed sensor. The VSS buffer converts the data from the vehicle speed sensor to a 4000 pulses/mile signal. The IPC uses the vehicle speed signal circuit (4000 pulses/mile) from the VSS buffer in order to display the vehicle speed. If the vehicle speed signal circuit malfunctions, the speedometer defaults to 0 mph (0 km/h). The speedometer displays both miles and kilometers.
