Code 10 on the other dash
The number alone is not enough. A Gen2 dash reads code 10 as Battery Temperature Warning Stage 1; a Gen3 dash reads the same number as Firmware Update Failure. 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 10 mean on a Zero Gen2 dash?
Battery Temperature Warning Stage 1. Battery temperature approaching limit. It is classed as warning: monitor the situation, may self-resolve.
What should I do about it?
Monitor temperature. Reduce load or charging rate.
Does code 10 mean the same thing on a Gen3 Zero?
No. On a Gen3 dash, code 10 is "Firmware Update Failure" — 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.
