I was able to test a few things tonight and would greatly appreciate any feedback from JoshS98, gbalthrop, NZE90, or anyone else!

First, I removed the fuse for the windshield wipers since they were constantly on after my DSC programming fail. Please let me know if this will cause issues in my troubleshooting.

I decided to start at connector X6021 which is in the white “DME” box on the passenger side of the engine bay. Most of my codes are DSC signals to the DKG and this connector is between the DSC and DKG in the wiring diagram.

Voltages by pin number at X6021 are:
5, PT CAN H, 2.581
6, PT CAN L, 2.34
7, PT CAN H, 2.583
8, PT CAN L, 2.34
9, 15WUP, 11.06
10, no wire
11, SP GND (ground for switch), 18.5
12, SP SIGNA (signal, shift paddle, 5.45

Next I took ohms for the following pins at X6021:
5 / 6, 60 Ohms back probing with connector in place, 120 ohms when testing with connector removed
7 / 8, 60 Ohms back probing with connector in place, 120 ohms when testing with connector removed

Next I verified ohms on CAN H and L at the OBD connector using the attached picture. Anyone know how to find the OBD connector wiring diagram in ISTA? I am not using the correct search terms because I can’t find the diagram.

OBD Test result:
CAN H / CAN L ,60 Ohms

Then I tested voltage at the EKP connector:
9, PT CAN H, 2.62
16, PT CAN L, 2.39

I believe all the results are normal, right? Where would you go from here? Check the connector at the transmission?

Finally, what do the splices look like? Actual connectors or some sort of butt connector or something like the PT CAN clear covers (picture below)?

Thanks again for your help. Hopefully I am going in the right direction!
