Displaying & Reading Trouble Codes

How to Retrieve a DTC

The Climate Control Unit has a self-diagnosis function.

Running the Self-diagnosis Function

1. Turn the ignition switch OFF.
2. Turn the fan switch OFF, the temperature control dial to Max Cool (60 °F or 18 °C), and the mode control dial to Vent.




3. Turn the ignition switch ON (II), then press and hold the recirculation control switch. Within 10 seconds while holding the switch down, press the rear window defogger switch five times. The recirculation indicator blinks two times and the A/C indicator comes on, then the self-diagnosis will begin. About 15 seconds later, the self- diagnosis will finish and the A/C indicator goes off. If there is any problem in the system after finished self- diagnosis, the recirculation indicator will blink the Diagnostic Trouble Code (DTC) 1 through 13. When problems in the evaporator temperature sensor circuit are detected (codes 14 and 15), the A/C indicator will blink the DTC. If no DTCs are found, the indicator will not blink.
