HI,
I am in the proccess of upgrading my nissan leaf 2012 white interier to 2022 40 kwh battery.

I though of it as pretty straight forward process, but I cannot make it to work.

I connected canbridge and rewired connector. Also interlock pins connceted on heater plug.

Leafspy show lots off errors: breaks, abs, hv battery interlock, can bus, etc.

Any advice on what to do?

Thansk.
 
This might sound trite but be sure your 12V battery is in good shape and fully charged. Otherwise, check out videos by Dala as he is an expert in this and has documented several of his swaps on youtube.

A bit more detail would help; at this point it could be anything.
Can you engage "drive"? Is power "limited"? Are you sure the 40 kWh pack was "good" (there should be no connections to the "heater" plug on the battery pack--I filled mine with silicone to prevent water entry).
I have done this upgrade (put a 40kWh pack in my 2011 Leaf), and there's lots of things that can go wrong.
