    B1475 means the A/C inverter (the electronic circuit that makes the A/C compressor motor move) got too hot and shut down.

    In gen 2, the A/C inverter was located in the big inverter assembly under the hood, and cooled by the flow of pink coolant like all the rest of that.

    But in gen 3, the A/C inverter is built into the A/C compressor, and cooled by the refrigerant passing through.

    The code might be caused by the wrong amount of refrigerant, or a problem with the condenser cooling fans, but if it isn't something simple like that, the fix will probably be compressor replacement. There just isn't that much else for it to be, in a gen 3.
