Code 32 on the other dash
The number alone is not enough. A Gen2 dash reads code 32 as Module Variance Too High; a Gen3 dash reads the same number as Contactor Open. 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.

Questions
What does error code 32 mean on a Zero Gen2 dash?
Module Variance Too High. Battery module voltage varying too much from other modules. Cells out of balance. It is classed as warning: monitor the situation, may self-resolve.
What should I do about it?
Perform balancing charge with onboard charger (<0.4C). Leave plugged in overnight.
Does code 32 mean the same thing on a Gen3 Zero?
No. On a Gen3 dash, code 32 is "Contactor Open" — 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.
