I have a weak cell that keeps me from getting Stealth miles 0-8 - which I'll fix someday. So, when my car tells me it detected a voltage variance issue basically once a week or when I get down below 20 Stealth Miles, I get that same code. I bought an OBDLINK device from Amazon for $69 and keep it in the OBD port (under the dash by your hood release) so I can whip my phone out and say "OK. Thanks. Now, please give me back my speedometer!!" I asked LorMax about those codes, and know that they are "livable".
I'm also hoping that the new Fisker might have some new options for us, regarding this.
Here's the link to the item I bought:
