  • [Corsa B 1993-2000] What diagnostics plug is this??

    HI,
    i've got a W plate 1.0L 12v Corsa B and i'm trying to find diagnostics fault codes.
    Bought a cheap OBD II fault reader on ebay but it wont sync with the car. It has the 16 pin connector but not all the plugs have wires in them, pins 3,4,5,7 and 16 have connectors (pic should be attached).
    Which cheap fault reader will work with this?Click image for larger version

    The three cylinder engines are a bit fussy which diagnostics they will talk to. If you have a laptop buy Opcom. Guaranteed to work on the 12v engine. Even some professional diagnostics can't read the 12v codes.

    Not all pins are always present in the diagnostic port.
