Speedometer (6.5L)

The vehicle speed is displayed in the IPC, based on the information from the VSS buffer. The VSS buffer monitors the vehicle speed sensor signal circuit in order to convert the data received from the vehicle speed sensor into a 4000 pulses/mile signal. The VSS buffer uses the vehicle speed signal circuit in order to display the vehicle speed in the IPC. When a malfunction exists in the vehicle speed signal circuit, the speedometer will default to 0 km/h (0 mph). The speedometer displays km/h and mph.
