    I'm strongly in favor of solving issues as they arise. Otherwise your car becomes this slowly growing heap of issues you've decided to ignore, and has warning lights always on so you can never tell if there's a new one, and it's halfway to jalopy status.

    The troubleshooting steps for that code in the repair manual run to five pages.

    Its winter again and the electric steering is starting to shake at low speeds. I am going to disconnect the power steering computer today. Do i need to unplug all 4 connectors or just any single one?

    You kind of have your choice of unplugging the torque sensor (that plug has skinny wires) as the ECU won't send any motor signals if it's getting no torque input, or just unplugging the motor (that plug has fat wires) so it can't send any motor signals. Or just unplug everything from the steering ECU and put it on your bookshelf. Yes, all of that by definition puts the steering completely in limp mode, but then that's the idea.

    ok got ya, i tried unplugging some wires today. Easy to find the module and also unplug the wires but got the annoying triangle and PS on screen. So i decided i am going to leave it plugged in for now but now i know what to do and how easy it is to unplug in case it gets a lot worse or wont stop.
