Code 42 on the other dash
The number alone is not enough. A Gen2 dash reads code 42 as High Battery Temperature Status Disable; a Gen3 dash reads the same number as Heated Grip 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.

Questions
What does error code 42 mean on a Zero Gen2 dash?
High Battery Temperature Status Disable. Battery too hot - motor disabled for protection. It is classed as warning: monitor the situation, may self-resolve.
What should I do about it?
Allow battery to cool before riding.
Does code 42 mean the same thing on a Gen3 Zero?
No. On a Gen3 dash, code 42 is "Heated Grip 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.
