Update: On my 2011, I went ahead and disconnected the TCU entirely, and have had no issues or noticeable changes in vehicle behavior for almost a week. If you are having 12v battery drain issues, or have a now-useless 2G TCU like me (Carwings update says "No service") then I'd recommend...

Is the OBD2 port under the dash just a female-female connector? You're saying I can put the Y splitter behind the OBD2 port? Would you mind posting a link for a part? (sorry I'm new! computer nerd, not car nerd)

Thanks for all this info! So in theory I could connect my OVMS (or any other OBD2 adapter) to pins 1-2 (battery +/-) and 9-10 (CANbus) of the TCU connector, rather than have it occupying the OBD port. I may try this once my OVMS arrives, as it would be nice to be able to run LeafSpy without...

I would very much like for OVMS to be a plug-and-play replacement of the TCU. I think this would require putting the OVMS on the white EV-CAN connector, as the codes being thrown are from the EV ECU not seeing what it expects on the EV-CAN. Is this the same bus that is exposed on the OBD port or...

You are correct, the relay clicking with LeafSpy happened again today with the TCU reconnected. On another thread here I discovered this can happen when the car is not powered on. Occasionally LeafSpy does not detect that the car is sleeping and addresses the car as if it were on. I also...

The white connector is the 1-40 pin connector on the left, which is used for power and EV-CANbus. The grey connector is the one in the middle, which connects the TCU to the touchscreen. Last night I decided to test this. I disconnected the 12v battery, removed the glovebox, then disconnected...

Sorry to revive an old thread, but I am finding conflicting info. For a Gen1, and for the purposes of wishing to conserve my 12v battery, should I disable the TCU by yanking the grey connector, the white connector, or both? The 2012 service manual shows the TCU receiving its power from pins 1...
