    ECU Error Codes

    Here's a handy chart for pulling your ECU codes. Pulling the code is a fairly easy process.
    For 92+ Honda's and 94+ Acura's:

    Before you can start reading the CEL (check engine light) in your dash, you need to 'jump' your ecu. Here's how.
    Located the factory two-pin connector of brown and black wires near the ECU on Civics del Sols and Integra's, or behind the center console for Preludes and Accords. Pull that 2-pin out of the main harness. Using a wire or paper clip as a jumper, connect the outputs of the harness together, so that the black wire and the brown wire make a circuit. Once this is jumped together, the dash will start the light show, so its a good idea to jump first, then turn to on.

    For 88-91 Honda's and 86-93 Acura's:

    The ECU's on these cars actually have a neat little window right on the computer case. No need to jump here- just turn it to on, and watch it right there through that window.

    For both steps above, the output will be in a Morse code style of long and short lights. For example, 2 long, pause, 3 short is 23.
