On a 2004 RX 330 I discovered while, cruising above 40 mph, turning slightly to the right, and slightly to the left the VSC light would come on and beep. Then, when turning a little more (but not hard), to the right or left. He would begin breaking until you let your foot off the throttle, and then it would slow naturally. However, when you would begin to reapply the throttle, it would begin breaking again. This creates a very dangerous situation on an acceleration ramp when everybody else is trying to speed up. It is also very dangerous on a deceleration ramp as it brings you down below this necessary speed to make the curve abruptly.
I have spent about eight hours over the last three days researching this, and only coming up with links to turn off the VSC and ABS light on the dash. I have also tried to re-calibrate it using the OBD connector for its auto diagnosis program. Unfortunately, this also had no effect. It seems as if the sensor is too sensitive to turning. Does anyone know if it would be the TPMS monitoring possibly triggering it or some programming within the ECM module?
any help would be appreciated. Thanks.
