How to Retrieve a DTC

The climate control unit has a self-diagnosis function.To run the self-diagnosis function, do the following:

1. Turn the ignition switch ON (II).




2. Press the AUTO button and then the OFF button. Continue to hold both buttons down.




If there is any abnormality in the system, the temperature indicator will light up the segment (A through N) corresponding to the error. The temperature indicator will then alternate every second between displaying "88" (all segments lit) and the error code segment (A through N). To determine the meaning of the DTC, refer to the DTC Troubleshooting Index. If there is no abnormality, the segments will not light up.
