Chalk up another ToD spasm to tire pressures. I drove the VX to work on Friday, and the check light was on from start. About half way to work it went off, but I was getting spastic indicators - no lights to all lights, to some lights...
Today it started out fine but the check light came on again. Then it went off but showed no indicator lights. I search and found this thread, so on the way home, I stopped at the gas station to check tire pressures... 45+ psi all the way around!?! How the heck did that happen?!? Even if I filled them to 33 psi on the coldest day of the winter, I would not expect that much of a pressure increase. It hasn't been serviced recently, so there was no reason to suspect a grease monkey mistake.
Anyway, all was fine and normal the rest of the way home. Hope it holds... I don't want to fix a car I am trying to sell!

Posted too soon... I think I summoned the wolf from the woods (a translation of a Ukrainian saying...)
The ToD spasms persisted after adjusting the tire pressures. I brought it in and they traced the problem to the ToD sensor wiring harness. The insulation wore away where the harness passed through/by/over/under the frame, and it was shorting out intermittantly.
Oddly enough, I had a similar problem over the 2007/2008 winter, but that time the wiring harness came loose and was resting on the catalytic converter, which of course melted the insulation and caused it to short out.
Zadam - have your ToD wiring harness checked. I saw your video, and it shows the exact same ToD light spasms I was having.

Sorry, I have no idea - I brought it to the shop to fix it (both times).

just curious did your tod go crazy only when almost comming to a stop like mine or was it all the time?

Mine was on and off, with no noticable pattern.
If yours is doing it only when slowing, then my guess is that the wiring is grounding out in only one direction when the chassis flexes on deceleration.
Wiring is not like an alternator or other fixed part - the wiring runs are by nature a little different on every car, so these kinds of issues are going to be unique to yours. When you slow down, you are throwing weight forward in the vehicle. Your wiring harness may only be grounding out where it hits the frame or something as it shifts forward under deceleration.
I paid for 3-4 hours of labor on each of my two ToD wiring repairs - it takes a while for the mechanic to diagnose, find, and fix this kind of problem.
