Reading Diagnostic Trouble Codes

NOTE: This is the only information provided by the manufacturer for 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 OFF.
2. Turn the fan switch OFF, the temperature control dial on Max Cool and the mode control dial on 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, then the self-diagnosis will begin. If there is any problem in the system after self-diagnosis is finished, the recirculation indicator will blink the Diagnostic Trouble Code (DTC) 7 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 DTC's are found, the indicator will not blink.
