jllowery Posted May 9, 2011 Posted May 9, 2011 I've got a 2001 rx300 (217k) awd and for the last few days a fast beep has been coming from the dash area. It was first only on curves and is now intermittently engaging even on straightaways or over bumps at any speed. A google search leads me to believe this is a vsc issue and there is surely a sensor somewhere that needs replacing or possibly the vsc can be overridden/disabled. The car runs fine but with this many miles on it I don't want to take it to the dealer and spend much money on it. In the 2wd models, I know there is a vsc switch, but don't think that is the case with the 2001 4wd models. Suggestions greatly appreciated. John

John There are only 2 sensors unique to VSC, a steering wheel rotational position sensor and "yaw" detection sensor. The first is integral to the steering wheel/assembly and the second is floor mounted, bolted to the floor. Under the rear seat I think. Try disconnecting the battery for 5-10 minutes to reset the VSC ECU. "..over bumps..." Loose yaw sensor, maybe "loose" internally.
jllowery Posted May 11, 2011 Author Posted May 11, 2011 Thank you so much, jaswood. I'll definitely do that tomorrow. I found myself on an open stretch of highway today and played with it a bit. When I swerve a little, as if steering into a skid, the beeping stops (until it starts again with a lane change or curve.
Cody2001xrlexus Posted July 3, 2020 Posted July 3, 2020 I'm experiencing the exact same issue in my 2001 Lexus is there anyway I can disable the beeping from inside the cab behind the dash it's going to drive me crazy
Tat2doc Posted July 6, 2020 Posted July 6, 2020 I have the same issue on a 2002 Lexus RX300. I have disconnected the ABS at the connector between the ABS control module and the coolant fluid reservoir and tried recalibrating the yaw sensor (although it did not do anything). I have not located the yaw sensor. Do you need to remove the rear seat to access that sensor?
