The OBDII connector is apparently functional, and the system is request-response (PID) based. So that video on polling OBDII PIDs will probably be a good starting point for you. I would work up from basics (first discover what ECUs are responding when the car is on, then find which PIDs are on each ECU, then try to decode the PIDs one by one). With a new car, I normally start with the obvious simple stuff like SOC% (which maybe on the standard fuel level PID). I also suggest you post on some of the Ioniq user forums, to see if anybody else is looking into this.</div><div class=""><br class=""></div><div class="">Regards, Mark</div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On 31 Aug 2022, at 7:40 AM, Michael Geddes <<a href="mailto:frog@bunyip.wheelycreek.net" class="">frog@bunyip.wheelycreek.net</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><div class="">Thanks very much Mark, that was very helpful.</div><div class=""><br class=""></div><div class="">OVMS Module ordered, with hopefully all the right cables :) and the dev kit downloaded and compile environment set up.<br class=""></div><div class=""><br class=""></div><div class="">Getting hold of service manuals might be a stretch, but I guess I'll reach out to a couple of people and see how we go!</div><div class=""><br class=""></div><div class="">//.ichael</div><br class=""><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, 24 Aug 2022 at 08:26, Mark Webb-Johnson <<a href="mailto:mark@webb-johnson.net" class="">mark@webb-johnson.net</a>> wrote:<br class=""></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="overflow-wrap: break-word;" class="">//.ichael,<div class=""><br class=""></div><div class="">Welcome aboard!</div><div class=""><br class=""></div><div class="">Can’t help much regarding the specific car, but can give some general pointers.</div><div class=""><br class=""></div><div class=""><ul class=""><li class="">If you can get hold of a service manual, it would be extremely helpful (if only for the wiring diagrams and information on which CAN buses and modules are in the car).<br class=""><br class=""></li><li class="">Have a look to see if anybody else has discovered and released CAN bus codes, OBDII PIDs, etc, or other information for your car.
