If you're disabling this feature by other means (cutting a wire or something like that) you'll risk damaging your traction control system.
Maybe because I had it in 1st then put in neutral it still did it...either way I did it when it wasn't in gear and it held the car when I took my foot off the brake. I did this today in my driveway.
