RAV4 2020 Hybrid Sniffing

Trying to sniff can bus for RAV4 2020 Hybrid. Unsuccessful to get any data from the PI. It fails every time. Auto detected bus details: [6] ISO 15765-4 (CAN 11/500), 500000

Tried a variety of alternate settings with no luck.

I am getting basic OBD2 messages from the vehicle - just nothing interesting.

Expected behaviour

Sniff packets to allow reverse engineering of some messages to allow integration with AutoPI

Actual behaviour

In the gui, I see “No connection to the device - No response” in a red popup. When I try in terminal, I see:

autopi1@Toyota RAV 4 $ obd.dump protocol=6 baudrate=500000 duration=1 CAN sending or receiving failed

I got a different message another time - something about RS232 buffer full…

Hello Greg,

To continue troubleshooting this issue, I would like you to do these steps:

  1. What output do you get when you run obd.commands in the terminal?
  2. Was the car running when you tried the commands?
  3. What output do you get when you run “obd.dump protocol=6 duration=0.1”
  1. What output do you get when you run obd.commands in the terminal?

GK

Hello,

It seems that you are able to get information from the vehicle.

Try running the command obd.query RPM with the engine running to see what results you get.


Some manufacturers create a “firewall” of sorts that blocks outside sources from listening to internal car system data. This means that if you are experiencing an issue of not being able to sniff any data, it might be the case that you can’t listen at all and you’ll have to instead query for that data.

Regards,
Alexandru
