If there is any problems in the system, the temperature indicator will light up the segment (A through S) 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 S). 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. If no segments light up, but the system is still not operating properly, check the sensor inputs to the climate control unit, or refer to symptom troubleshooting. |
