What needs to be replaced after the pedestrian protection system is triggered?

Components related to the pedestrian protection system need to be replaced, including the hood, hinges, lift rods, etc. Here is additional information: 1. Precautions: The pedestrian protection system is designed to reduce injuries to pedestrians in the event of an accident. The system is a one-time-use component and cannot be restored once triggered. You should immediately contact a 4S dealership for repairs. Continuing to drive on the road may pose safety risks to yourself and others. 2. Principle: The pedestrian protection system works by installing an active hinge and a specialized lifting device at the end of the engine hood, along with cameras on the vehicle body and pressure sensors on the bumper. When the vehicle collides with a pedestrian, it prevents the human body from directly hitting harder objects upon impact. The raised hood creates a buffer zone between the body and the engine compartment, thereby protecting the pedestrian.
A few days ago, my car accidentally hit something, and the pedestrian protection system immediately activated, causing the hood to pop up quite high. During repairs, I was told that the hood lifting device had to be replaced—it was designed for one-time use. Additionally, the sensors and control module, similar to an ECU, needed replacement as they were responsible for detecting and triggering the action. It was also recommended to check the bumper and front wiring to ensure no other damage from the impact. I paid around a thousand bucks myself, but considering it helps protect others, it felt worth it. Now, I drive even more carefully, reminding myself to check these systems before every start. After the repair, a reset test was necessary to ensure proper operation next time. Never overlook this issue—safe driving comes first.
