Code 47 on the other dash

The number alone is not enough. A Gen2 dash reads code 47 as MBB Charger Connected Disable; a Gen3 dash reads the same number as Memory Fault. And the model name does not settle it: the S, SR, DS and DSR kept their names when they moved from the Sevcon dash to Cypher III in 2024, so it is the year that tells you which table applies.

Does code 47 mean the same thing on a Gen3 Zero?

No. On a Gen3 dash, code 47 is "Memory Fault" — a different fault entirely. The two tables share numbers but not meanings, so read the one that matches your dash, not your model name: the S, SR, DS and DSR kept their names when they moved to Cypher III in 2024.
