well theres no need to even check the ECU unless your Check Engine light is on...if not, dont worry about it...thats a good thing lol.
No check engine light = no major problem = ECU wont even say anything to you
just curious, did you go back to the FIRST post where Leon explained how to do everything? lol...or you did, and you just still didnt understand it?

On the 1991-1995 Acura/Honda Legends, you have to jump a service connector located on the passenger side right under the dashboard near the door. The connector has two pin inputs. Connecting them with something like a paper clip will force the check engine light on the dashboard to display the codes.
Extracting Codes
With the car either running or the key in the ON position, perform the necessary steps above and observe the blinking of the light. The light will blink displaying all the codes in sequence and then repeating them.
Reading Codes
The code numbers are read by counting the number of blinks between longer pauses. On 1986-1990 Legends, the code number is indicacted by a series of rapid LED blinks between longer pauses.
On 1991-1995 cars, codes 1-9 are indicated by a series of short flashes; two digit codes use a number of long flashes for the first digit followed by the number of short flashes for the second digit. So a code 43 will be represented by 4 long and 3 short flashes.
The position of codes in a sequence can be helpful in doing diagnostics. A display showing 1-1-1-pause-9-9-9 indicates two problems occurring at different times. A sequence showing 1-9-1-9-1-9 indicates two problems occurring at the same time.
