Try This First - Powertrain Malfunction / High-Voltage Battery Warning / Service Vehicle Soon While Charging

Someone on reddit said that their tech cleared some codes by doing something with the hazard lights (cycling them 3 times?), I hadn't heard this one before for this issue, any idea?

Is the car 'fully off' when you push the 'off' button after parking, close the door, (and lock it)? Or is it like a computer and has 2 or 3 'offs'.

The car is not fully off until 2 hours after shutdown.

That doesn't seem correct. That would affect the BCM only and sounds like a TPMS reset thing.

My question related to the phrase " Turn OFF the vehicle completely." My computer has: normal off, sleep off, and power off. The on/off button seems to be another peculiar kind of 'off'. Because it senses when I approach with a key or my phone at least part of it is awake.

Yes. I guess the best way to describe it is the car is in various states of sleep. The only way to have the car fully off is to disconnect the 12 V battery.

In context of the article, I mean that you can’t use accessory mode, and you can’t have screens active.

Seeing this method again tonight and it seems to be fixing SSN DTCs

You can add Flo public L2 chargers to the list. Although I've used a lot of these units over the past year, I found some particularly troublesome units over the week-end.

The interesting thing is I could trigger the SVS message when the car was plugged in and charging and I remote started it. Charging would stop and I'd return to the car with a nice SVS message.

For some reason this L2 really did not like that combination.
