Checking for DTCs

The temperature display indicates single or multiple DTCs. If no DTCs are present, the indicator remains blank.

NOTE: If driver's temperature indicator segments A, B, C, E, G, J, and M with the AUTO indicator, the MODE indicator, and the WINDSHIELD DEFROST indicator are on at the same time, there may be an open in the sensor common ground wire.
