On-Board Diagnostic System Check Operation:

Heating, Ventilation and Air Conditioning (HVAC) Diagnostic Trouble Codes (DTCs) can be cleared from the Heater and Air Conditioning control by pressing the "OFF" button while DTCs are displaying the HVAC pointer -02. After DTCs are cleared, the display will show "00." The Tech 1 scanner can also be used to clear DTCs.
