Code 33 on the other dash
The number alone is not enough. A Gen3 dash reads code 33 as Battery Module Awaiting Connection; a Gen2 dash reads the same number as SEVCON Error Turn Off. 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.
