Perfectly normal to have with the 58v FICM

It's normal? I have a 58v and no code

[Dave]

What are you reading codes with?

[kdogg85]

Livewire and cts both show it, but read 58v koeo, koec, koer. I seen the code and went, oh crap. But checked voltages and everything is the same as the day I put it in. just checked codes while getting strategy for matt.

Not recently. But after installing and several months later after new alt and batteries. No check engine or codes on the insight
