You probably got the speed wrong. When in active mode, the system will actively respond to messages on the bus, and if the baud rate is wrong that messes things up. In listen mode, the system won’t write to the CAN bus at all, so is more tolerant to baud rate mismatch (you will get garbage messages instead). Regards, Mark.

We have full support for CAN dumping.
My first attempt failed, instrument cluster and driver information center went crazy when I turned the car on (and I couldn't start it) but I changed the can bus mode from CAN_MODE_ACTIVE to CAN_MODE_LISTEN, lowered the speed to CAN_SPEED_500KBPS (1000 is probably ok but will test later) and got a nice pcap file to poke at in my leisure.
Thanks for the hints!
