How to Retrieve a DTC (Without HDS)

The audio-HVAC display panel has a self-diagnostic function for climate control. To run the self-diagnostic function, do the following:

NOTE: If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN system diagnosis test mode A.

1. Turn the ignition switch ON (II).
2. Set the driver's temperature control dial or button on MAX Cool.
3. Press and hold the OFF button.




4. While holding the OFF button, press the rear window defogger button five times within 10 seconds. The self-diagnosis will begin.

If there are any problems in the system, the temperature indicator will light up the segment (A through Q) 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 Q).

NOTE: The system will only display the DTC when the AUTO and OFF buttons are pressed. If you release the buttons, the display will go blank. To return the display, simply press the AUTO then the OFF buttons again.




To determine the meaning of the DTC, refer to the DTC Troubleshooting Index. Diagnostic Trouble Code Descriptions If no segments light up, the system is still not operating properly, check the sensor inputs to the climate control unit, or refer to symptom troubleshooting.

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.
