LeLink2 ordered and will try that likely next week to see what is available on the CAN Bus.
In the meantime, here are some CAN frames if anyone has any wisdom they would like to share on which CAN IDs correspond to what parts of the system.
I found this page https://github.com/dalathegreat/leaf_can_bus_messages but can't seem to link the IDs described to the data I have captured.
@isak if possible it would be great to know if the sequence below indicates what is wrong, I have a text file of the whole sequence I can send you. This is a lot of work so no problem if not, but would be great to know what each ID corresponds to. Thank you
Will see what leafspy says next week, failing that I will be ordering a new OLED.

The PDM doesn’t clear the firewall lol, at least if your adapter plates are the same thickness as mine. Hence why I removed mine, can send some pictures of the motor and PDM mounts if that helps
@RufusL That is some good info to know in advance thanks. I would love some pictures of your motor and PDM mounts. Always wanted to try welding - this may be the time. As the PDM is mounted I cant tell how the radiator/fan is situated. Are you using the original truck radiator?

Could there be an issue where the inverter or motor is missing a ground to the chassis? Could the input power to the inverter be hot but something in the controller or BMS not activating because it is missing a pathway to chassis ground in the 12 system that it would normally have through the physical connection with the pdm that is now gone? Not sure if I am thinking this out fully but might be worth establishing a temp route to chassis from the inverter housing just to see if that might be the problem?

@badkins I’ll get some photos to you soon, my first proper welding job too, pretty simple if you use some thicker material, I’ve got a hobby gas mig welder and that’s doing the job fine.
Good thinking re. the motor ground, I’ve actually got a connection from the inverter casting to battery 0 V so will be sure to check continuity but I don’t think that’s it.
Not using the truck radiator, the PDM is there cos it’s the best space I could find for it with my limited fabrication skills, plan to mount a radiator horizontally above the wheel arch, being EV a small one should do with a decent fan is my thinking. -

Managed to get leafspy connected. Reads out the cell voltages so I guess BMS CAN working. Unsure how to test PDM and inverter but will look into the app instructions a bit more.
Anyone understand these error messages before I get into the documentation?

Cleared the codes today to try and power back on but LeLink wouldn’t connect again, gutted. Going to try another reader as it’s connecting fine to another app and read similar issues online between leafspy and lelink.
The first time it did connect and managed to “read ECU versions” but didn’t get much of a readout, bit concerning but not sure until I get a reliable connection. Can anyone share a screenshot of leafspy ecu readout on there resolve setup?

Finally got the wheels turning, LeafSpy connected for long enough to do some DTC fault finding. Errors reported as expected when disconnecting different parts of the system, only when the inverter was disconnected no change in DTC.
So I checked the inverter connector for continuity and there was a wire break on the ground. Nice easy solution despite lots of investigation.
Time to find space for the batteries.
