Temperature Display

The DIC applies voltage to the ambient air temperature gauge sensor. The ambient air temperature gauge sensor is a thermister (the temperature and the resistance vary inversely):
^ As the resistance of the ambient air temperature gauge sensor increases, the DIC senses a larger voltage drop across the sensor, indicating a lower temperature.
^ As the resistance of the ambient air temperature gauge sensor decrease, the DIC senses a smaller voltage drop across the sensor, indicating a higher temperature.

If the temperature is below 3°C (37°F) the temperature digits will toggle between displaying the following items for 2 minutes:
^ The outside temperature
^ The word ICE

This condition occurs once per ignition cycle. The DIC uses the vehicle speed signal from the Powertrain Control Module (PCM) in order to determine when to update the temperature display with a new outside air temperature reading. The vehicle must be driven over 16 km/h (10 mph) before the temperature display updates.
