I bought a 24h pass and there are lots of diagrams and how tos. I do miss the service protocols though. Also no firmwares for download that I could find.

I asked in another thread to about service protocols but I have yet to find them...

 

I'm not sure what service protocols are (how to perform a service?), but I'm sure Hyundai keeps some information only available to official dealerships.

 

Here is an archive with repair manual for Ioniq 2017

I am trying to find the manual for the new Ioniq 2020

 

hi

 

hi, I found something interesting here:

HYUNDAI - Workshop Manuals

HYUNDAI Workshop Manuals - Complete and illustrated to perform the repair and maintenance of your vehicle. Immediate download in pdf.

manuali-officina.com

 

Superhero, you are right about missing protocols and firmware on those official sites. I found that some of the paid workshop manuals might skip over specific calibration procedures or deeper diagnostics which are often dealer-only access. Still, the diagrams are solid and super helpful for DIY repairs. For service protocols, I would say double-checking user forums or specific enthusiast groups they sometimes have hidden gems. And always back up any ECU changes before diving into firmware-related work.

 

For my last three cars I have taken out subscriptions to Alldata DIY just to understand what repairs and maintenance I can perform or to better understand what a technician may be saying to me. The minimum subscription is one month ($19.00) and they go up from there.

I see that they have the Ioniq 5 listed under “Hyundai - trucks”…go figure! . in fact I have just purchased a one month subscription which I hope will shine some light on the mysteries of our cars.

 

There's a similar discussion here. I bought the Service manual for the Hybrid, couldn't find one for the '38 sadly.

That Hyundai workshop manual site is definitely a goldmine for official info but yeah it is frustrating that some key details like firmware and deeper diagnostics are dealer-only. I have found that combining workshop manuals with forum discussions and YouTube walkthroughs helps fill in the gaps, especially for trickier jobs like ECU resets or ADAS calibrations. If you're diving into anything electrical always triple-check wiring diagrams and test with a multimeter before swapping parts it saves a ton of headaches.

 

They ripped me off all I got was some kind of useless encrypted PDF. And now even it seems to have a time limit as well.

 

Welcome to the modern "subscription model". Some manufacturers are even making drivers pay for subscriptions on features built-in to their vehicles.
