: In some cases, it may be a "ghost code" caused by missed programming or external interference, such as certain aftermarket USB dongles.
On the road, it defies physics. The unibody construction (a point of contention for purists) means it doesn't wobble around corners like the old models. It feels planted and surprisingly agile for a box that looks like a brick.
: This signal is often used for features like speed-dependent volume or "Active Sound Design" (which pumps synthetic engine noise into the cabin).
