Post custon PIDs with DBC file

Hello bro..

I have a DBC file so I know CAN ID.

(CAN ID : 809)

How to put PID for OBD2 PID Editor?

Just put ‘809’ only?

DBC files are for interpreting broadcast CAN data that is being sent around the vehicle. Torque isn’t designed for this.

PIDs work on a request/response communication so are only there if you ask for them.

You might be able to trick Torque into sending a request and making it think the broadcast message is the response but you’d have to be careful which CAN ID you send the request on as it could cause issues if it’s not a standard diagnostic one.

If you have a more expensive interface like an OBDLink there are also some extra commands that might work.

What’s the vehicle and what signal are you after?

My car is hyundai i30N and I’m using OBD link lx.
The only information is that ‘steering wheel angle’ can id is 809.
So I was planning to put can id 809 and press test button for response and reverse engineering.

try external PID, which I posted above, and check in Torque
the data that you have given, there is a lot to do with my data
