How to Retrieve a DTC

The audio-HVAC display panel has a self-diagnosis function for heating, ventilation, and air conditioning system. To run the self-diagnosis function, do the following:

1. Turn the ignition switch OFF.
2. Turn the fan switch OFF.
3. Set the temperature control dial on Max Cool, then push the mode control button to select Vent.
4. Turn the ignition switch ON (II).
5. Press and hold the recirculation control button.




6. While holding the button down, press the rear window defogger button five times within 10 seconds. The recirculation indicator blinks two times, then the self-diagnosis will begin.

- If there is any problem in the system after self-diagnosis is finished, the recirculation indicator will blink Diagnostic Trouble Code (DTC) 1 through 6. If there is any problems in the evaporator temperature sensor circuit the A/C indicator will blink DTC 7 or 8.
- If no DTC's are found, the indicator will not blink.
