Outside Air Temperature Indicator Test
Outside Air Temperature Indicator TestNOTE: To test the outside air temperature sensor.
Troubleshooting:
If the indicator displays "-" for more than 2 seconds after selecting the outside air temperature display mode, check for an open in the BRN/WHT wire between the gauge and the outside air temperature sensor or the GRY wire between the gauge assembly and the climate control unit.
Calibration:
The outside air temperature indicator's displayed temperature can be recalibrated ±3 °F to meet the customer's expectations.
1. Turn the ignition switch ON (II), and make sure the outside temperature is displayed.
2. Press the select/reset switch button for 10 seconds. While you continue to hold the button, the display will scroll through temperature settings from +3 ° to -3 °F as shown.
3. When the desired correction value appears on the display, release the button, and the recalibrated outside air temperature will be displayed.
Each time a desired correction value is entered, it replaces the previous value.
Example:
Uncorrected value = 68 °F
Desired correction value = +2 °F
Corrected value = 70 °F
Desired correction value = -2 °F
New correction value = 66 °F
NOTE: To recalibrate the display to the true temperature, remove the outside air temperature sensor (A), but leave it connected. Submerge the sensor and a thermometer (B) in a container of ice water (C). Select the calibration mode as described above, then recalibrate the display to the true temperature.
