| Actuator Recalibration | 
| 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.
