How to turn on "show me everything on the bus, please" mode
I have a Scantool.net OBDLink SX, which I presume is based on the STN1110. I can connect just fine using either the supplied OBDWiz or a terminal program.
My problem is I'd like to monitor traffic to sniff out non-standard PIDs, but I'm not having any luck. Maybe this tool/chip just can't do it, but I've done it with an old original ELM327 some time ago, so unless I've forgotten an important step, something is different.
Can anyone tell me how to turn off filtering so I can see the various modules talking to one another?
