Trailer Stability Assist (TSA)

TSA is activated automatically upon installation of the trailer module.

The purpose of TSA is to stabilize undamped self-oscillations, which can occur when driving with a trailer. TSA works together with the vehicle's DSTC (Dynamic Stability and Traction Control) system, and stabilization is achieved through braking on one or more of the vehicle's wheels and through reduction of engine torque.
