Pcm (ECM/TCM)
WARNING: This page is about a different car, the 2021 Hyundai Kona. However, it is still accessible from the selected car via links, so may be relevant.
The AVSM (Advanced Vehicle Stability Management) is a safety function which prevents a vehicle from crashing with the integrated control by the SCC (Smart Cruise Control) centered on the ESP (ESC). The SCC computes the likelihood of a collision with a radar that senses the speed and gap of a vehicle ahead. In case of crashing it reduces damage from it through the IBAU controlling the SCC system.
The ESP (ESC) exchanges signals with the ECM, TCM, SCC via CAN lines in order to control VSM properly.
