WTF,
I don't care if it's just the infotainment system.
Engine (prime mover) should be off for any update on any vehicle.
I'm just wondering why you felt the need to include "(prime mover)"
Did you just like typing it?
To be fair it’s a pretty cool way to describe an engine
Because it's a main source of active power that can be re-directed.
A battery on an EV can be too, in which case the main contactor should be verified disconnected prior to any software update. But typically people don't refer to that as the 'engine'.
So prime mover encompasses engines and main batteries.
So the motor on a fuel based car is the prime mover, but the battery on an electric car is the prime mover, rather than the motor?
I'm guessing then that you would call the tyres the terrestrial contact devices? 😂
Yes. The primary source of power.
It's not like I'm making shit up out of thin air. This is typical nomenclature for safety systems.
If you have an air system, the prime mover would be an pressurized air tank or accumulator.
Properly recognizing the prime movers of a system and defeating them correctly is part of safety.
Agreed, it’s a waste environmentally, on my pocket book, waste of time (do you have to babysit this thing while it’s updating?) and is unnecessary wear and tear on the engine.
The electrics stay on on my car when you turn the engine off, until you open the door. I don’t see why that behavior can’t be overridden until the update is done, and then turn itself off.
It's a safety issue.
Crazy inexplicable things can happen when modern cars have electrical control access to brakes/steering/throttle.
Firmware doesn't take right, download message emulates by accident another message, random bit flipping that even CRC checks miss.
There's no reason to risk any of that. Just shut the engine off.
