Where to find CAN buses/lines ?

Post by Lawris » 2018 May 21 13:46

Hello everyone, first post here :D

Since a lot of new cars (including my Toyota Hilux REVO) use the OBD port as a gateway, I can not sniff any data traffic. I can only send requests with specific codes that I do not have (if someone have them, feel free to share :) ).

So I want to connect to the different nodes buses/lines including body, comfort, engine... But I actually don't know where to find them ?

Also, I don't know if it's a good idea to directly connect to the ECU or the BCM (Body Control Module) ?

I'd be very grateful if anyone could help me find some (easy to access if possible :lol: ) CAN buses.

Loris.
