me parece que, hay que apretar el auto y el dual a la vez y encender el coche, y soltarlos
After leafing through the 04/05 Service Manual, I came across a couple of diagnostic modes that you can enter without hooking the car up to the Honda Diagnostic System. I haven't tried this on mine yet (just got it a couple of days ago), but give it a try and let me know what you think...
From page 21-11 (Climate Control section):
The climate control unit has a diagnostic mode that allows you to view sensor inputs that it receives. To run the sensor input display mode:
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 ©.
3. Solar radiation sensor value (00=dark, 10=cloudy, 65=sunny).
4. Engine coolant temp ©.
5. Evaporator outlet air temp ©.
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 ©.
That's right - you have a digital speedo in your car!
