Where can I connect the CANUSB interface?

Hello.

Where can I connect the CANUSB interface?
I connected to the infotainment bus to retrieve radio data, but I'm not seeing MFA (Multi-Function Display) data (ID = 3C2). I can also connect to the CAN bus for the climatronic.

Where did you do that, and was it connected?

Thank you.

I've connected the CAN hacker to the comfort CAN bus near the climatronic control unit.

Okay.

I have connected there as well.

I disassembled the air conditioner and welded two wires to pins 5 and 6 of the large connector, specifically the connector that connects to the air conditioner.

I have configured can tool 1.99.08 to 100 kbit/s, but I'm not seeing ID = 3C2 (the ID from the MFA). Do you need to start the car's engine to view the data?

A greeting and thank you very much.

I haven't checked yet to see if I can 'see' the 3C2.
Do you see the ID 575?
You can also use it to check the ignition status.

0x575 bytes, line 1.
Bit 0 = S contact.
Bit 1 = Ignition (15) interior.
Bit 2 = X contact.
...
Bit 6 = Ignition (15) engine.

'But, can you retrieve data from ID 3C2? Are you connected to the CAN bus with orange/green and orange/brown wires on the Climatronic?' Do you want to start the engine?

I use the Climatronic system to display data such as turn signal status, road lighting status, etc.

Greetings.

hi,
Okay, regarding the Golf 5, I would be cautious because there's an infotainment system and a comfort module (which are separate and work together via the CAN gateway, but not all messages are necessarily passed directly to all buses).

So, if ID signals are present (ignition on, engine doesn't need to be running), then I would say you're connected to the wrong CAN bus.

Another possibility: Do you even have MFA Plus (FIS?)? If not, this ID doesn't exist! If you do, does anything appear?
