Vehicle Speed Display

The HUD displays the vehicle speed based on information from the vehicle speed sensor. The ECM converts the data from the vehicle speed sensor to a 4,000 pulses/mile signal. The HUD uses the vehicle speed signal circuit (4,000 pulses/mile) from the ECM in order to calculate the vehicle speed. The HUD displays either miles or kilometers as requested from the DIC. The associated indicator (km/h or MPH) illuminates in the IPC.
