Start engine. AC on 72f. Press and hold "rest" button on CCU for 5 secs to enter diagnostic mode. Post values 1-8, use L/R auto buttons to toggle. Press rest to exit.

The get error codes and post also: Turn on the ignition, and set the left CCU temperature to "HI" and the right temperature to "LO." Then, simultaneously press buttons "Rest" and "EC" for five or more seconds. All of this must be done within 20 seconds. The "Recirculate" button will flash its LED. The screen will then go blank, and the first code can be brought up by pressing the right "AUTO" button.
