Where is ECU on 2003 Odyssey

[Maxumis]

Where is the ECU on the 2003 Odyssey and how do I check it? Where can I find a ECU decoder?

the ECU is under the center of the dash on the floor. Peak in by the gas pedal and you should see it. Why do you need to check it? And what do you mean by decoder?

In my 99 Nissan Maxima you can tell what is wrong with the car by turning a little screw on the ECU and a light blinks on the dash...for example 9 fast blinks and one slow blink of the light means the O2 sensor is bad. How is the Honda Odyssey set up to determine what is wrong with the vehicle?
