Outside Temperature Display: Adjustments
Outside Air Temperature Indicator TestCalibration
NOTE: This procedure must be done after the temperature sensor stabilizes.
The outside air temperature indicator's displayed temperature can be recalibrated ±3 degrees to meet the customer's expectations.
1. Turn the ignition switch ON (II).
2. Press and hold the reset select button for 10 seconds. While you continue to hold the button, the display will scroll through temperature settings from +3 degrees to -3 degree 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 valve is entered, it replaces the previous valve.
Example:
Incorrect value = 68 degrees F (20 degrees C)
Desired correction valve = +2 degrees F (+1 degree C)
Correct valve = 70 degrees F (21 degrees C)
Desired correction valve = -2 degree F (-1 degree C)
Correct valve = 66 degrees F (19 degrees C)
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.
