Hidden diagnostics
Are there some climate control unit "hidden" diagnostics like the TSX on the TL ? There has to be ! ! !
I don't have the service manual and didn't find anything on this forum yet ?
Here's the link for the TSX

I don't need the owner's manual, it came in french and english versions with the car. 
I gave it a try on my 08 TL-S and no success, too bad. . . works like a charm on my 07 TSX. Someone please tell me it can be done without hooking the car up to the "Honda Diagnostic System".
TSX instructions:
1. Turn the ignition switch off.
2. Press and hold both AUTO and DUAL buttons, and start the engine.
3. After the engine starts, release both buttons.
4. The audio-HVAC display will flash a sensor number, then value for the sensor.
5. To adavnce to the next sensor, press the rear window defogger button.
6. To cancel this mode, press AUTO, or turn off ignition.
Sensor numbers, descriptions, and display values as follows:
1. In-car temp (degrees C).
2. Outside temp (C).
3. Solar radiation sensor value (00=dark, 10=cloudy, 65=sunny).
4. Engine coolant temp (C).
5. Evaporator outlet air temp (C).
6. Driver's air mix opening (low=cool, high=warm, %).
7. Passenger's air mix opening (low=cool, high=warm, %).
8. Vehicle speed (km/h).
9. Vent temp air out (C).
