The interesting (?) thing with these rather BAD readings (case : L-sensors log2 shown) is the naif/bad design of the whole BMS-K "error/fault management" capability:
I mean whilst is rather obvious that "something" is going rather bad in cyl2, no warning message is displayed in I-Cluster, nor
any kind of fault code (BMS-K inquired via GS911) is stored in memory. What it happens actually is that the BMS-K is trying to handle a hopeless situation that can't been handled.
It's not a mystery why the extremely slow responding GT-1 super gizmo (kinda) can't report anything bad.
Who designed the system? Was he (or she) some graduate student?
