It's not talked about on this site, but it's a thing in almost all Toyota/Lexus models - zero point calibration.
I have not researched this topic enough to understand it fully, but it's generally recommended after any sort of suspension, alignment, steering rack work, that a zero point calibration be performed on the yaw rate sensor. This calibrates the skid ECU so that it's reading accurately, such that it responds properly to driving conditions.
I'd imagine there's many of us that are due, especially if an alignment has not been performed at a facility that is aware of the procedure. If one gets unexpected VSC intrusions, it's very likely a calibration needs to be performed.
I'm also interested in hacking this... Wonder if this same sensor feeds the ECU/transmission map such that we could effect shift points for larger wheels, by making the vehicle think it's going uphill.
