Reading Diagnostic Trouble Codes

How to Retrieve a DTC
The heater control panel has a self-diagnosis function.

Running the Self-diagnosis Function




1. Turn the ignition switch ON (II).
2. Turn the fan switch OFF, and the recirculation control switch to Recirculate (recirculation indicator light comes on).
3. Press and hold the recirculation control switch to Fresh (recirculation indicator light goes off). Continue to hold the switch until the recirculation indicator light comes on for 2 seconds, then it will blink the Diagnostic Trouble Code (DTC) to indicate a faulty component.
