Calibrating the HVAC Actuators

NOTE: The HVAC module will initialize and calibrate the actuators. The purpose of the HVAC module actuator position calibration is to allow the HVAC module to reinitialize and calibrate the actuator stop points.

To calibrate HVAC actuators, Carry out the following steps:

1. With the ignition on, select any mode except OFF on the HVAC controls.

2. While pressing the RECIRC mode button, select OFF on the HVAC controls.

3. Continue holding the RECIRC mode button for 5 seconds after OFF is selected.

4. Select PANEL/FLOOR mode on the HVAC controls.

The recirc mode indicator flashes at the rate of 1 flash per second for the duration of the actuator calibration. After the calibration is complete, the recirc mode indicator resumes flashing to indicate any DTCs. DTC 1-1 indicates no faults present.
