of measurement (mph or km/h).
A string of dashes "---" is displayed with the set unit
of measurement if:
- speed is equal to 186 mph or 299 km/h or if
dashboard is not receiving the speed value ("---"
steady on);
- the rear speed sensor is in fault ("---" flashing,
EOBD light on and SPEED SENSOR error
