HVAC SYSTEM CALIBRATION This procedure may be performed on both the ATC and MTC system. 1. Start engine and let run. 2. If the vehicle has an ATC system, turn the control head on. 3. Set the temperature controls to the full cold position for 2 minutes. 4. Set the temperature controls to the full heat position for 5 minutes. © 2008 Mitchell Repair Information Co., LLC.
