This is my first post. I have a 2000 LC100. Just finished replacing instrument panel with LED bulbs and they really look great. First time I drove after the change, the VSC trac & VSC off lights turns on about 5 seconds when put to gear. Did I mess up something in the instrument panel or I have a real problem with my vehicle skid control system? any advise is appreciated.

Sounds like the skid control system needs a zero point calibration. Not sure why changing the dash bulbs would do that though?
Happened to me as well. Researched it a bit and some 4Runner guys had that happened to them. Checked everything and concluded it was the voltage change from the LEDs that triggered the lights. The code I get is c1207 (PNP switch circuit (P/R range). Installing new/old bulbs (had to order some new ones from Cdan) next week and seeing if the lights go off and no more codes show. Which is fine, I wasn't happy with the LED lighting for the dash/console - too bright at night and the blue was a little too boy racer.

Thanks for all the replies. Gwatts nailed it and it is the voltage change. But if I may add that changing the PRNDL to led's is what causing the Vsc trac and Vsc off to turn on. I put back old bulbs but retained led's in the gauges. no more problem!! the PRNDL led's are to bright anyway!!
Glad you were successful. I put all OE bulbs back in today, cleared the code and the VSC TRAC and VSC OFF still came back. Wonder if there is more going on with mine.
I think there is some write up on Zero point calibration here somewhere. Going to try that.
