Which country? If in the USA, most likely you'll find an OBD-2 under driver's dash area. But if you found the 17-pin connection then the DS708 should be able to do some diagnostics through it possibly. Good luck

  Ok, so I am guessing you have not tried connecting the 626 with the Mazda software along with the 17-pin adapter; Try it first using Mazda software, since the OBDII software only works with the OBDII 16-pin port under dash. You might also try to use the Ford software under USA tab and if available in your DS708, EU Ford under Europe tab with 17-pin adapter; under either one of these software you will find when choosing the manually vehicle selection, the selection for the 626.

FYI, under Mazda or Ford software you will find under the manual vehicle selection (3rd option when starting software) the option for 626/626 wagon/Tesltar along with option for the 1.8L, 2.0L, 2.5L engines and which after selecting type of engine(s), the appropriate manufacturing years can be selected. Hope this helps and good luck.

   Hi Thomas. I see you are still having issues connecting with your Mazda. At this moment I would recommend you perform a data log as you have been trying to connect with your vehicle. Follow the instructions on the link I provide you for this step; then send it to Autel and they usually guarantee a fix within 48 hrs! Plus it is about your satisfaction with their product and proper guarantee functionality of the software and hardware. I also have provided a few more links in regard to your vehicle that might be handy while you wait patiently for a fix. I'm glad to be able to help you as I can.

** A little bit of research I did for your generation 626 and found out that it is or was also called in Europe and Japan as the Capella. I checked that it can be found under the vehicle selection and that only certain years are available for the Capella, 1999 being the last year selectable. I don't know if you might like to try once more and link up your car by selecting Capella under the Mazda or EU Ford. It seems worth another attempt.

 Hi,
Did they solve your problem. I am having the same error.
