Title: Car CAN buses
Post by: Erwin Ried on October 19, 2022, 12:46:29 pm

I understand that there is 2-3 different buses in most cars. I want to remote start and switch the climate controls on my kia optima phev

Knowledge you can share?

(I tried to install a OEM remote start kit for the gasoline version… but did not work, tries to start but fails I guess because the hybrid does not start the gasoline engine inmediately https://photos.app.goo.gl/8BRGg1W6pW1EmHFCA so now I should Arduboy-DIYit)

But isolated from each other? Which ones? Because for example thinking on kia/hyundai I think there is 3, one base for important stuff, brakes etc, other for the cluster and secondary stuff like climate and other exposed for diagnostics (based on what I have read)
