Module order and temperature sensor help

[Supermans1]

Hi I have a problem with a erratic tempature sensor
So am gonna drop the battery and fix it
What I want to know if someone knows is the order
I have 27 modules in my battery pack
With 2 tempature sensors in each so total 54
The pack is daisy chained
I have number 52 that’s dodgy and keeps shutting the battery down
Am I right in thinking that 52 would be module 26 second from the end
Any help be great
Yes I now it’s 400v I’m a electrician I work on 1kv all the time so have all correct tools and ppe

You'll probably need to give a bit more information on the battery pack, is it an OEM pack or a custom one?

It’s a oem vivaro 75kwh pack
3s4p
27 module
Daisy chained
9x slave bms that controls 3 modules each
can find nothing really apart from a few posts about them stripped down
Thank you
