Speedometer

The IPC displays the vehicle speed based on information from the PCM. The PCM 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 PCM in order to calculate the vehicle speed. The speedometer defaults to 0 km/h (mph) if a malfunction in the vehicle speed signal circuit (4000 pulses/mile) exists
