How to Retrieve a DTC (Without HDS)

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

NOTE: Before troubleshooting the climate control system, refer to B-CAN System Diagnosis Test Mode A Troubleshooting. Troubleshooting - B-CAN System Diagnosis Test Mode A

1. Turn the ignition switch ON (II).




2. Press and hold the OFF button. While holding the OFF button, press the recirculation button five times within 10 seconds. Release the OFF button and the self-diagnostic will begin.

NOTE: The blower motor can be run at any speed regardless of what the panel is displaying.




If there is any problem 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). To determine the meaning of the DTC, refer to the DTC Troubleshooting Index. Diagnostic Trouble Code Descriptions

If there are no problems detected, the segments will not illuminate.

Canceling the Self-diagnostic Function
3. 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.
