[edit] Reading the Codes

1. Locate the factory diagnostic plug next to the ECU for the Integra. You'll find this plug in the passenger side foot well underneath the far right hand side of the glove box. There is a two-pin connector that contains a brown and black wire.
   

   
2. Jump these two wires together and turn your key to the ON position.
   

   
3. Deciphering the code requires reading the light sequences. When the car is in the ON position, the check engine light emits two different flashes; a long extended flash means 10, and a rapid flash means 1. So, one long flash, another long flash, followed by 3 quick flash stands for 23. Equipped with that information, here are the codes for the Integra.
