| Note | ||
| Do not adjust any controls on the HVAC control module while it is performing self-calibration. Interruption could cause the HVAC system to malfunction. | 
When replacing the HVAC control module it will be necessary to allow the HVAC control module to perform a calibration process. When installing the HVAC control module be sure to perform the following:
| 1. | Place the ignition switch to the OFF position. | |
| 2. | Disconnect the scan tool. | |
| 3. | Install the HVAC control module. | |
| 4. | Connect all previously disconnected components. | |
| 5. | Ignition ON. | |
| 6. | Wait 40 s for the HVAC control module to self-calibrate. | |
| 7. | Verify that no DTCs have set as current DTCs. | |
When replacing the HVAC actuator it will be necessary to allow the HVAC control module to perform a calibration process. When installing the HVAC actuator be sure to perform one of the following:
