1992 Elantra: How can I read the Engine Control Unit Codes?

Discussion in 'Hyundai Elantra / Lantra' started by Jean Castonguay, Nov 23, 2005.

  1. First of all, is it possible?

    If it is, how can I do it? My Chilton book does not explain it.

    Thank you very much for your help.

    There's a connector in your fuse box. One of the pins provides code output
    for your engine computer, another for your trans computer. Go to
    www.hmaservice.com and register for an account. Once you get your
    password, go to service information, select your vehicle and the shop
    manual tab. In the fuel section, the manual should give you a good
    picture of the connector and the procedure for checking the engine codes.
    I've done this with an analog voltmeter and simply counted the meter
