  • obd1 or obd2 ?

    How can I tell if my car has a type 1 or a type 2 onboard diagnostic system ? In 1993 through 1995 they seemed to use both 12 pin and 16 pin connectors and both types of ecm/pcm computers in various combinations for no particular reason. Anyone got a clue ?
    Thanks

    I think in 94 you have ODBI computer with an ODBI connector too..
    My 95 has an ODBI computer with an ODBII hook up, I would think because this is the year they changed from I to II with 3.4 to 3.8 so they used the ODBII hookups.. my best guess. I couldn't tell you why a 93 or 94 would have an ODBII hookup.

      On some 94-95 F-Bodys They used a kind of hybrid OBD2,It was called OBD2 maufacturers specific.The ALDL looks more like an OBD2 generic connector,but the OBD2 generic connector will NOT hook up to it! You'll need a scanner that has that style of interface cable,.www.autoXray.com has all types of interface cables to go with their scanners, or find someone that has that type of cable.
