Outside air temperature indication

This indicator shows indication of outside air temperature while ignition switch is in ON position.
Ambient sensor is used commonly by auto air conditioner and this board computer. When auto air conditioner operates, board computer will correct ambient sensor signal based on positive voltage signal to terminal 56 of board computer from A/C auto amp.
Indication range is between -30 and +55°C (-22 and 131°F). (When outside temperature is less than -30°C (-22°F) or more than +55°C (131°F), display shows "- - - -".)
When outside temperature is less than 3°C (37°F) continuously, display will blink as a warning. In this case, the display will change to the OUTSIDE AIR TEMPERATURE mode even though the display is showing a different item.

1. When vehicle speed is more than 20 km/h (12 MPH).
2. The ignition key has been turned to OFF position for more than 3.5 hours.
3. When outside temperature is lower than indicated temperature.
