Code 41 on the other dash
The number alone is not enough. A Gen2 dash reads code 41 as Low Battery Voltage Disable; a Gen3 dash reads the same number as Motor High Temperature. 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.
Which bikes use this table
Sevcon-era dash: S, SR, DS (2014-2023), DSR (2016-2023), FX (2014-2025), FXS (2016-2021), FXE (2022-2025). The SDS and XMX owner manuals print the same 0-63 table.

Questions
What does error code 41 mean on a Zero Gen2 dash?
Low Battery Voltage Disable. Battery voltage too low - motor disabled for protection. It is classed as warning: monitor the situation, may self-resolve.
What should I do about it?
Charge the battery immediately.
Does code 41 mean the same thing on a Gen3 Zero?
No. On a Gen3 dash, code 41 is "Motor High Temperature" — 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.
