Cannot reach my gateway

Hello everyone,

I've built a device that I plan to use later to connect to and diagnose the speedometer and other control units on the workbench. I initially tried to access the gateway using VCDS, but I haven't been able to. The control unit is not responding.
The gateway is connected as follows:
Pin 1: Constant positive voltage.
Pin 2: Constant positive voltage.
Pin 9: Can Bus Low diagnostic connector + OBD2 Can Low Pin 6.
Pin 11: Ground.
Pin 12: Ground.
Pin 19: CAN Bus High diagnostic connector + OBD2 CAN High. Pin 14.

OBD2.
Pin 4: Ground.
Pin 16: Continuous positive voltage.

The gateway is from VW, part number 7N0 907 530.

In this configuration, the gateway should be accessible, right? Can someone perhaps say something about that ?

Regards,
Arth.

You haven't connected the CAN.

Did you forget to write that, or was your question a joke?

OBD Can is connected to gateway pins 9 and 19. The question is no joke; I'm trying to establish a connection to the gateway.

Now I understand what you meant; the OBD2 pins were included in the list above. Unfortunately, you have your H and L reversed.

Best regards, Rainer.

Thank you, Rainer, great help! That's all. And I can finally continue. Great forum, great admin
