i have a 2000 gs-300.
occasionally when i drive over a bump, the check engine light,vsc light and vsc off light all come on, then i am unable to accelerate the vehicle. i then pull over and shut the car off, the lights may or may not appear again and drive off. it's a little dangerous when you just lose your ability to move.
has anyone heard anything about this. i didn't really get any help from the dealer, other than the sensors may be a problem. but it mentions these lights coming on on the owners manual, and says bring it to a dealer

Possibly a old connector. Check the 3 electrical connectors going to the throttle body. Make sure they are fully clicked in. Also check for any damage on the wires.
