OK, gotta ressurect this one.

Thanks to Alain for this pic of 96+ TCU:


Question 1: What's the box labelled U / D? That's not a schematic symbol I recognize. I think it must be a relay, but the pins aren't labelled, and it's the wrong symbol.

Question 2: What's the Circle marked "F11" "(1)" "Off/Run/Start" supposed to be? It's not labelled "Ignition", so that's not it.

It seems to me the F11 circle should be the "Arm" switch, the one that would be triggered by pushing a real autostick over into the autostick "neutral/O" section of the gear selector. But the schematic doesn't show it with a ground or a switch symbol, so it can't be a switch.

Question 3: Isn't a hall-effect switch a magnetic, 3-position switch?
