VSC dash light comes on in hot weather

[Blicky]

Gday everyone
I recently Brought a 2000 LX 470 with 280,000 k’s on the clock, it runs like a charm but I’m having an issue with the VSC – light coming on during the warmer parts of the day. It can be sitting there and I go to get in it when it has been hot and it is warm inside the cabin of the car and the light comes on immediately or I can be driving and as it gets warmer throughout the day the light will come on. I have read the posts about the light coming on and applying the brakes to one wheel but I am not experiencing this issue. It has been back to the dealership I brought it from three times and they still haven’t fixed the issue, they now say they need to replace that yaw rate sensor located under the dash somewhere which they seem to be unable to find. I’m located in rural Victoria Australia and have limited Lexus dealers nearby. Any one have any suggestions as to what this may be other than the sensor for me to check?
Cheers

check your power steering rack bushings......often overlooked, mis-diagnosed, trust me i spent weeks trying to figure the issue out, replaced speed sensors all sorts of trouble shooting, you can buy a kit on amazon for cheap to replace the bushings...i have dont the job for all three of mine,,,no more VSC lights or abrupt braking caused by the sensors....can be dangerous too i almost had an accident when the vehicle thought it was loosing traction and the ABS engaged the front right wheel while i was going 60MPH through a overpass curve.......made me almost crap my pants....its not a simple job but can be done you have to engineer a long piece of all thread with a nut and some big washers to get two of the bushings replaced....but way cheaper than a new power steering rack///

There is a post showing how to turn off VSC which may buy you some time until you can fix it.
