How to Retrieve a DTC

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

1. Turn the ignition switch ON (II).




2. Press the FAN UP button and then the FAN DOWN button. Continue to hold both buttons down.




If there is any abnormality in the system, the DTC indicator will light up the segment (C, D, I, J, K, L, M, or N) corresponding to the error. The DTC indicator will then alternate every second between displaying "88" (all segments lit) and the error code segment (C, D, I, J, K, L, M, or N). To determine the meaning of the DTC, refer to the DTC Troubleshooting Index. If there is no abnormality, the segments will not light up.

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.
