Thanks Michael for the info on Repidscan. Looks useful!

I have just received/configured/'installed' my OVMS device today! Looks like the "Niro/Kona" config is giving me the most information.. . so I will start from there.

When I say installed: the OBD cord is running into the holder below the USB ports (in a way that I won't trip on it while driving). I'll get round to getting a SIM at some point (I've attached the aerial) - and hope I can get it working. I will make sure I get the latest code.

One of my work colleagues has dealt with diagnosing messages on the CAN busses of rubbish trucks at his last job, so he may be a useful resource for me as well!

Wish me luck.

Michael,

regarding OBD2 device & PID detection I suggest using my web UI, which makes things a lot easier:

Thanks again. I had a look at the video about CAN decoding you referenced so at least know where to start. I have cloned the simplistic Ioniq definition already there as a launch point, and there was a longer list of Can messages on a github repo referenced in that forum post you referred to.

The Ioniq 5 ordering in Australia is different but also has its issues due to scarcity of getting them into the country.

- Orders are all online through Hyundai Australia rather than through showrooms. So can't see them in showrooms.

- Orders are first - come-first serve as they open up batches of cars to specific States. Usually about a 10min window to snatch one up.

- you can request to do a test drive before you take delivery and do final payments but not b4 you place order.

- insentives are state dependent and are starting to come in

I was lucky/persistent enough to get one in the first (even more chaotic) round. 40 mins of navigation through an oveloaded website. Made worse because of 3hr time difference between eastern states and where I am in Perth.

Anyway, next step is waiting for the device to get here!

I was interested in the Ioniq 5 for myself, perhaps to replace my ageing Model S. But just got a rather amazing reply from the local distributor (who promotes it as available her). Summarising:

Can see the car in the showroom

No stock for sales

No test drives available

Tentative 2024 pricing

2024 Q2 for next delivery batch

Can pre-order for that with large non-refundable deposit

Incentives may be gone by then

Looking online, it seems some people have started looking at the ionic 5 CAN bus. 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.

Thanks very much Mark, that was very helpful.

OVMS Module ordered, with hopefully all the right cables :) and the dev kit downloaded and compile environment set up.

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!

//.ichael,

Welcome aboard!

Can’t help much regarding the specific car, but can give some general pointers.

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).

Have a look to see if anybody else has discovered and released CAN bus codes, OBDII PIDs, etc, or other information for your car. For example this looks pretty good and probably covers most of what is needed for the Ioniq 5: https://www.ioniqforum.com/threads/torque-pro-pids-for-ioniq-5.37793/

The left/right direction for OBDII cable is purely cosmetic. It depends on the cleanest direction for the cable to route. The standard is OBD2 (aka OBDII). OBD1 was obsolete in 1995 and irrelevant nowadays. Pictures below.

Developers Guide is linked here. https://www.openvehicles.com/developers. If using windows, you can follow the “Developing with Visual Studio Code (on Windows)” instructions there. If using Linux/Mac, you follow the “Vehicle Firmware Development Tools (Linux/Mac)” section.

The firmware code is C++, and there is plenty of example vehicle support code there.

There’s a pretty good YouTube video on using OVMS to reverse engineer OBD PIDs that you can find here: https://www.youtube.com/watch?v=8RwV2e-Fg7g

I’m working on my own series of YouTube videos on OVMS. The upcoming (but not yet released) ones are also on CAN buses and reverse engineering. You can find the channel here: https://www.youtube.com/channel/UC97jOb8YLhYMBhJ4zrCx9XQ

Hi,
I have an Australian Hyundai Ioniq 5 (no BlueLink or HUD in the current versions). I'm also a developer; have mucked round with some hardware stuff, but it's been a bit.

I'm looking at whether it's worth attempting to use OVMS on my Ioniq 5. Has anybody already started on this? The idea of providing mapped OBD commands through to a HUD is definitely appealing, as would be getting charge status stats remotely.

If I were to start, which cable would I be best to get? Is it left or right that I need? The port is to the right of my right-hand-drive steering wheel. At least I'm pretty sure that's the OBD2 port. I'm new to ODB so not even sure how to recognise OBD vs OBD2!

What I know:

The old Hyundai Ioniq is a model that has EV, ICE, Hybrid, Plug-in Hybrid versions. The Ioniq 5 (and Ioniq 6, 7 etc) are part of a sub-brand based on E-GMP EV platform that is also shared by the Kia EV6.

So I don't know whether the old Ioniq or Kona would be a good start.

Skills:

* C/C++ (though I'm currently using Delphi), so happy to with different 'real' languages.

* I could solder up a lead or circuit board, but wouldn't be able to design a circuit board.

* I've dealt with software on a custom embedded controller (albeit in Forth + Forth assembly)

Any advice on this? I have older kids; the youngest is about to finish High School - so a new hobby might be a good thing to have :).

Pointers to good introduction to ODB2 and the Ioniq 5 specifics if anybody has them would be welcome!
