Does the sniffer transmit any signals to activate the truck's CAN interface
Posted: Wed 14. Aug 2024, 08:47
Hello There. First time blogging here.
Currently working on a project where we use PCAN View installed on a PC and PCAN-USB tool to sniff Telemetry data on vehicles.
We can sniff whole CAN data with 250 kbit/s on the European vehicles (Scania, Mercedes), the FMS standard evolved from J1939 standard. On certain particular models, I have observed that while we are able to get complete CAN data when unchecking Listen-only modegeometry dash subzero, we are only able to retrieve a single stream of data (eg tachograph) when checking Listen-only mode. I simply want to receive; I am not attempting to send any messages.
Thus, my query is: Does the sniffer transmit any signals to activate the truck's CAN interface thereby enabling complete CAN data output? If so, what message this conveys?
I value your assist in this.
Respects
