Speedometer

The IPC displays the vehicle speed based on the information from the vehicle speed sensor. 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 mph (0 km/h) if a malfunction in the vehicle speed signal circuit 4000 pulses/mile exists. The speedometer displays either miles or kilometers as requested by the activation of the English/metric button on the Driver Information Center (DIC). The associated indicator km/ or MPH) illuminates in the instrument cluster and the head up display.
