Getting canbus traffic from a running vehicle via an ODB port
Posted: Thu Mar 07, 2024 4:48 pm
Hi, as I understand/have been told. If I'm wanting to read canbus traffic of a vehicle in order to reverse engineer it I'll need software that can make ISOTP requests to get the vehicle ECU to send relevant data.
This is where my understanding ends however.
I'm potentially going to try and get data from a lexus UX300E on its BMS control and 2 can busses. The only way I'm likely going to be able to do this is via an ODB port. So....
Does anyone have any tried and tested methods for doing this?
I've got a Toyota techstream ODB->usb adapter on the way with techstream v18, to access the battery can networks I'll need to make some ISOTP requests, what software (ideally free) exists that can do this and is it easy to then use said software to requests the required data? Thanks
