Calibration Procedure

The outside air temperature indicator's displayed temperature can be recalibrated ± 5°F (or ± 3°C) to meet the customer's expectations.

1. Turn the ignition switch to ON (II).
2. Select the odometer/trip A or odometer/trip B display.
3. Press and hold the RESET switch for 10 seconds. While you continue to hold the button, the display will scroll through temperature settings from +5°F to -5°F (or +3°C to -3°C) as shown.

4. 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°F (20°C) 

   Desired correction valve = +2°F (+1°C) 

   Correct valve = 70°F (21°C) 

   Desired correction valve = - 2°F (- 1°) 

   Correct valve =66°F (19°C) 

   NOTE: The recalibration temperature is not the value the sensor sees. Therefore the temperature can only be adjusted ± degrees from the sensor.
   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.
