Reading Diagnostic Trouble Codes
How to Retrieve a DTCThe heater control panel has a self-diagnosis function. To run the self-diagnosis function, do the following:
1. Set the mode control dial on the Vent position.
2. Turn the ignition switch ON (II).
3. Within 5 seconds after turning the ignition switch on, press the recirculation control switch the required number of times depending on the recirculation indicator status:
- If the indicator is ON, press the recirculation control switch 5 times.
- If the indicator is OFF, press the recirculation control switch 6 times.
The recirculation indicator will come on for 2 seconds, then blink the Diagnostic Trouble Code (DTC) to indicate a faulty component. If no DTC's are found, the indicator will not blink after the initial 2 second light.
