Reading Diagnostic Trouble Codes

How to Retrieve a DTC

The Heater Control 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. Press the recirculation control switch and the rear window defogger switch.
3. While holding the both switches down, turn the ignition switch ON(II).




4. The self-diagnosis will begin, and run for about 15 seconds.
- If there is any problem in the system after self-diagnosis is finished, the recirculation indicator will blink the Diagnostic Trouble Code (DTC) 7 through 15.
- If no DTC's are found, the indicator will not blink.
