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 car's DSTC (Dynamic Stability and Traction Control) system, and stabilization is achieved by braking one or more of the car's wheels and reducing engine torque.
