How to Retrieve a DTCThe heater control panel has a self-diagnostic function. To run the self-diagnostic function, do the following:
1. Turn the fan switch OFF.
2. Press and hold the recirculation control switch and the rear window defogger switch down.
3. Turn the ignition switch ON (II).
4. Release both switches. The recirculation indicator and the rear window defogger indicator come on. The recirculation indicator goes off 3 seconds later and the A/C indicator comes on, then the self-diagnostic will begin. About 10 seconds later, the self-diagnostic will finish and the A/C indicator goes off.
- If any trouble is found, the recirculation indicator blinks the diagnostic trouble code (DTC) to indicate a faulty circuit or component.
- If the system is OK, the recirculation indicator stays off.
Canceling the Self-diagnostic Function
5. Turn the ignition switch OFF to cancel the self-diagnostic function. After completing repair work, run the self-diagnostic function again to make sure that there are no other malfunctions.
