Code 10 on the other dash
The number alone is not enough. A Gen3 dash reads code 10 as Firmware Update Failure; a Gen2 dash reads the same number as Battery Temperature Warning Stage 1. 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
Cypher III dash: SR/F and SR/S (2020+), DSR/X (2023+), S/F, and the S, SR, DS and DSR from 2024, when those four moved to the FST platform.

Questions
What does error code 10 mean on a Zero Gen3 dash?
Firmware Update Failure. Firmware update failed because the cellular signal was too weak. It is classed as warning: monitor the situation, may self-resolve.
What should I do about it?
Retry somewhere with better cellular coverage.
Does code 10 mean the same thing on a Gen2 Zero?
No. On a Gen2 dash, code 10 is "Battery Temperature Warning Stage 1" — 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.
