How to Use the Self-diagnostic Function

The heater control panel has a self-diagnostic function for heating and ventilation system. To run the self-diagnostic function, do the following:

1. Turn the ignition switch OFF.
2. Press and hold the recirculation control and rear window defogger buttons, and turn the ignition switch ON (II).







3. Recirculation indicator turns on for 2 seconds, then self-diagnostic function begins.

NOTE:
- The blower motor will run at any speed regardless of the dial positioning.
- In the case of multiple problems, the recirculation indicator will blink the lowest number DTC only.
- If no DTCs are found, the indicator will not blink.

Clear the DTCs
When the problem is repaired, DTCs will automatically clear.
