We've already established this as a working function which I do not doubt one bit. By continuing to call this a VDIM disable is truely false as VDIM controls other safety functions mentioned above for the new GS430, IS350, RX400h, Highlander Hybrid just to name a few. I think alot of people have no idea what VDIM really is as they confuse VDIM with TRAC and VSC over and over, time and time again. BTW, you can spin the tires and lay some nice rubber tracks on the ground with just TRAC OFF (from the dash button next to the ECT PWR switch) but as the wheel speed gets to 35 mph, the computer will re-enable TRAC (retard engine power and actuate ABS) as it was designed to do. When i find time, i will render that part of the video and load it for everyone to see.

You dont really know, you are just assuming. :-). I very much doubt VDIM interveens anymore or does anything at all with its two major components disabled.

Obviously they are not going to tell us how VDIM would be totally disabled because of legal issues, but what they have told us in our presentation of it's function is very logical. BTW, what does VDIM matter to people to those who have never experienced it or really know how it works? Seems like the people who don't have the car or have no intentions of buying it are the ones who seem to be all torn up about having a non exisitent VDIM control in the first place.

After 30 minutes of research... I can only find a way to turn off VSC//TRAC. There is no "VDIM OFF" mode. The VSC/TRAC OFF was designed for (as someone stated multiple times) chassis dynoing. The EBD is only disabled if the ABS system is malfunctioning. It's surprisingly busy at work today... so I'll read up the rest of the repair manual later and post up what systems are disabled and when.
An the only way to disable other systems on command is using the "GAME GENIE" hahahaha... (test tool)

why is everyone hung up on the terminology. how about this:
+ ( ....start the car with the parking prake on ....then foot brake twice....(keep the foot brake down)....then parking brake twice (keep it down )and repeat till skid light is on the dash )

However, VSC and TRAC are also standard on the IS250, so yes you should be able to disable VSC and TRAC simultaneously the same way.

Have any 250 owners tested this yet? Or is there a trac button on the 250's that when pushed would disable both trac and VSC?

THx! Does the TRAC button in the 250Rwd actually keep TRAC off past 30mph?
Also, if anyone has tried the parking brake, foot brake sequence in a 250 to turn off VSC and Trac, I'd be curious to know whether it worked.

TRAC OFF should automatically reactivate above 30mph as a default.

Even today, can you do an real burnout with trc off, or does it re-activate due to simply too much wheelspin? (and below 30-35 mph).
Keep in mind that main reason for trc off switch is to be able to move car in snow when trc would simply make it impossible...
