This is a Tool that we have rigged to take care of the VSC Lights @ SC Forum. It is about $3 off fleabay. Weld PINs as needed...
Get your tool made and follow this:
The problem is solved by putting a jumper on 2 pins in the OBD-II connector under the dash. I think a lot of owners have this problem especially after being scanned for code. Some scanners are not built the same-- that seems to be the explanation. Anyhow, here it is, with a little bit of modification as it suits the SC430.
1. Turn off ignition.
2. Look for the OBD-II connector under the dash, it has a black plastic cover which can be pulled out.
3. Using a 4-inch wire, insert ends on two pins (holes) of the OBD-II connector. Which ones? The connector has two rows of holes with pins inside. The connector's shape is basically rectangle but there's a little wedge shape to it. Like this:
______
/---------\
/-----------\
(see picture below)
I will call the narrower side of the connector the top row, and the wider side to be the lower row. Jump the following pins:
a) on the top row, counting from the left, where the first pin is 1, insert on pin number 3
b) on the bottom row, counting from the left, insert on pin
number 5.
4. Turn ON the ignition, do not start.
5. VSC and Check Engine lights turn ON. That's normal.
6. Wait for the VSC light to rapidly flash.
7. Turn OFF ignition.
8. Pull jumper wire out, cover the OBD-II connector.
9. Turn ignition ON, don't start, wait about 15 seconds to make sure everything has initialized.
10. Start car. Test drive. You've just saved yourself couple of thousand dollars.

A few additional points,
1) Many of the posts regarding the clearing and resetting of the zero point calibration showed a few different jumper configurations on the DLC3 connector when compared to the one shown above. They did not work for my car. Only the jumper configuration shown above worked for my car. Be sure to make sure you put the jumper wire into the correct pin locations. Double check this.
2) I did not need to put a weight on the passengers seat or press on the brakes.
3) I did disconnect the battery prior to this procedure. I read in one Toyota source that this was required. I'm not sure if this is in fact true, but I did it anyway. Be sure to reinitialize your windows, moon roof, and back hatch after disconnecting the battery.
4) For some reason, the vsc off light only came on after I drove the car a few feet after turning on the car. It did not turn on after starting the ignition and leaving the car stationary. Again, I would have to drive a few feet or more for the dreaded light to turn on. It would not turn off while driving.
5) Lexus wanted $40 for the diagnostic read and $100 to reset the zero point calibration. No thanks. I did it myself.
6) One Lexus service "adviser" told me that the resetting of the zero point calibration was only needed for errors related to the airbags. This is not true. This error light comes on after various car modifications and repairs as explained in the article above. You would think this "adviser" would be better informed.
7) I did not want to take the chance of Lexus finding "some fabricated problem" and charging my big money for a problem that does not exist.
Well, I hoped this helped. Let me know if you have any questions.
Take care,
Rich
