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

1. Turn the vehicle to the OFF (LOCK) mode and then the ON mode.

2. Press and hold the ON/OFF button, then within 10 seconds press and release the REAR WINDOW DEFOGGER/MIRROR DEFOGGER button five times. Release the ON/OFF button. ALL LCD segments come on for 2 seconds, then the self-diagnostic function begins.

NOTE:

The blower motor will run at various speeds regardless of what the panel is displaying.
If there is any problem in the system, the temperature indicator flashes "88". Refer to checking for DTCs.
If there is more than one DTC, they are displayed one at a time in sequence followed by a pause (all the display indicator segments illuminate) between the DTCs.
If no DTCs are present, the temperature indicator will flash "no".

Canceling the Self-Diagnostic Function

4. Turn the vehicle to the OFF (LOCK) mode to cancel the self-diagnostic function. After completing repair work, run the self-diagnostic function again to make sure that there are no other DTCs.
