Diagram for TCM pinout, TCM CAN bus wiring diagram needed?

Hi Andrin,

You like these wiring problems :) Here is a guide to help with the testing and the wiring diagrams for the TCM and CAN BUS, please start a new post for the ECU wiring. I don't have connector views for this car, sorry. Check out the images (below). Let us know if you need anything else.

They make work very easy. Thank you.

You are welcome.

Hi Ken, I noticed the TCM is not appearing on the network. I could not find the can for the TCM, but I got a code P1590, referring to a damaged TCM or ECM. I just need to verify the can, if good then I replace the TCM. I also noticed this model has a gate way module. I did not find it in the diagram you shared with me, can you please?

I don't think the car has a gateway module, where do you you see it? To me it sounds like you have a TCM that is out, I would make sure it is getting power and ground and if so, replace the TCM. Use the wiring diagrams above to test. Here is the location of the TCM.

Thank you, Ken, we found a blown fuse after noticing the TCM was not getting power.

Nice work Andrin! glad you got it fixed, have a nice weekend.
