Code 44 on the other dash
The number alone is not enough. A Gen2 dash reads code 44 as Kill Switch 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.
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.

What does error code 44 mean on a Zero Gen2 dash?
Kill Switch Disable. Kill switch engaged - motor disabled (normal). It is classed as informational: normal operation events, no action required.

Does code 44 mean the same thing on a Gen3 Zero?
No. On a Gen3 dash, code 44 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.
