    what is isolated ground? And where it is connected in a vehicle?

    Thanks,

    people here hesitate to answer questions related to automotive apps generally.

    an isolated ground is exactly what it sounds like - isolated from all other voltage planes.

    usually it is a separate poured plane on a PCB which acts as a floating ground reference of sorts - separate from both an earth ground (physical) or a digital ground reference for logic devices.
