How can I check over rev throw ODB2 without dealerships?
Buy a Hyundai GDS if you have the loose cash available.
AFAIK you cannot. You need a Hyundai GDS diagnostic device or something similar to read such data.
@Bullet; You're correct about the OEM GDS, as you have to be a Hyundai Dealership or Service Department and they have proprietary software. There are some alternatives below but are costly.
