Driving under normal conditions, typically around a curve our traction control will engage. Car immediately slows, dashboard warning beeps/lights for a few seconds and then back to normal. My mechanic and Toyota dealer could not replicate it during test drives to get error code. Any advice on how to diagnose and what it could be?
This had happened to me when i used those portable ram. I just unpluged the negative battery terminal for a couple hour then the problen went away. It did not come back after that.
