Traction Control Activates on S curves

4209 Views 3 Replies 4 Participants Last post by  hutzi69
I live on a curvy country road. All of the sudden traction control now activates on the S curves that I have been driving for years at the same speed, etc. Shocks, etc. seem fine, but this new problem is quite annoying! Any ideas how to diagnose/repair?

Hi, I'm from Germany and my dealer has no repair guide for the Toyta Sienna: So maybe is there so to help me:

Where is the control modul for the tire pressure warning system? The yellow light is always on and the mechanic cannot find the control modul to inactivate it.

Thank you so much for helping!!
