Gauges Symptom Troubleshooting - Outside Air Temperature Indicator Does Not Change: Notes

Outside air temperature indicator does not change 

How to use this manual .

NOTICE: 

Before you troubleshoot, review the How to Troubleshoot .

NOTE:

• Before troubleshooting, check the B-CAN DTCs. If any DTC is indicated, troubleshoot the indicated DTC first.
• Outside air temperature is indicated based on the measurement value of the outside air temperature sensor located behind the center of the front bumper. Because of the location of the sensor, it may be affected by heat reflection from the road, engine and radiator heat, or hot exhaust from surrounding traffic. To display the outside air temperature, the gauge control module has an indication mode based on engine coolant temperature and vehicle speed. Some modes do not raise the temperature indication, so the outside air temperature indication may not change when the mode continues.

Outside Air Temperature Indication Mode
Indication Mode	Indication Temperature Increase	Indication Temperature Decrease	Notes
Initial Indication			If the current outside air temperature is higher than the indicated outside air temperature since the last time the vehicle was turned OFF (LOCK) mode, and the engine coolant temperature is higher than 140 deg.F (60 deg.C): The last outside air temperature that was indicated before the vehicle OFF (LOCK) mode is displayed. If the current outside air temperature is higher than the indicated outside air temperature since the last time the vehicle was turned OFF (LOCK) mode, and the engine coolant temperature is less than 140 deg.F (60 deg.C): The current temperature measured by the outside air temperature sensor is indicated. If the current outside air temperature is lower than the indicated outside air temperature since the last time the vehicle was turned OFF (LOCK) mode: The current temperature measured by the outside air temperature sensor is indicated.
Garage Mode	Increases 1 deg.F every 1 second (or 1 deg.C every 2 seconds) to the current outside air temperature.	Decreases 1 deg.F every 1 second (or 1 deg.C every 2 seconds) to the current outside air temperature.	If the engine coolant temperature is less than 140 deg.F (60 deg.C) when the vehicle is ON mode, the mode shifts to the garage mode.
Traffic Jam Mode		If the outside air temperature is less than the indicated temperature, the temperature decreases by 1 deg.F per 1 second (or 1 deg.C per 2 seconds).	If the engine coolant temperature is 140 deg.F (60 deg.C) or more, the mode shifts to the traffic jam mode NOTE: Once entering to the traffic jam mode, the mode does not shift to garage mode, even after the engine coolant temperature is below 140 deg.F (60 deg.C) or the vehicle speed is below 1.2 mph (2 km/h).
Stable Run Mode	Increases 1 deg.F every 17 seconds (or 1 deg.C every 30 seconds) to the current outside air temperature.	Decreases 1 deg.F every 1 second (or 1 deg.C every 2 seconds) to the current outside air temperature.	If the vehicle speed is at 19 mph (30 km/h) for more than 58 seconds, the mode shifts to stable run mode.
