Mirrors - Temperature Display Inaccurate



MIRRORS - TEMPERATURE DISPLAY INACCURATE

DIAGNOSTIC AIDS
- An inaccurate temperature display indicates an abnormal resistance condition within the system.
- For intermittent diagnosis, refer to Testing for Intermittent Conditions and Poor Connections. Component Tests and General Diagnostics

Ambient Air Temperature Sensor Resistance:




The following table will be used to measure the resistance of the sensor and compare it with the actual ambient temperature. The mirrors temperature accuracy should be within 5 degrees of the actual temperature. The actual temperature should not be taken from a radio station, a sign displaying the temperature, etc. A temperature measuring tool such as a thermometer should be used. Some temperature measuring tools may be within 5 degrees of the actual temperature. Make sure to consult the manufacturer for the accuracy of the tool. This comparison can make the mirror seem off by 5-10 degrees of the actual temperature when it is not.
