So you have heard of this happening ????? Never experienced anything like that before quite frightening when you have an Artic up your rear Honking at you & it won't go .My Mechanic has worked on Van's quite a lot & never seen this before. It's only done it once on me & I'm now paranoid , looking down where my right foot is ..."big foot syndrome". Most disconcerting when it happens, but resets after a few seconds (and I'm pretty sure the code clears itself after a somewhat longer interval).
