| Description of the problem | While driving on dry pavement, sometimes, but not always, after leaving snowy driveway, the 2004 awd toyota sienna's traction control light came on. This was accompanied by a very loud alarm. The traction control system then activated causing the engine to brake and the abs to continuously brake until the vehicle decelerated to appx. 9 miles per hour. The light and alarm would then go off. The whole scenario repeats when speed exceeds appx. 9 miles per hour. This puts the driver in a very dangerous situation. The vehicle is very difficult to steer when is it rapidly braking. This happened both at low speeds, start-up speeds, and on the highway when i was going 40-50 miles per hour, again, on dry pavement. The only safe option is to pull off to the side of the road. After driving for anywhere from 3 minutes to 15 minutes, the problem mysteriously disappears. The next time the vehicle starts, it may or may not malfunction in this way. The tires are in good condition and at appropriate inflation levels. There does not appear to be any snow or ice on or inside the wheels when this is happening. *nm |
