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

It is necessary to replace the vehicle's front hood and its accessories, the external airbag system, the sensors of the pedestrian protection system, and the braking system. Here is some relevant information about the pedestrian protection system: 1. Basic version: It can be said that mid-size cars are the easiest among all vehicle types to implement pedestrian protection, as their body dimensions (including the front part) can basically ensure that the head of a pedestrian contacts near the center of the windshield during a collision. This allows for reducing the head injury criterion by modifying the energy absorption design in this area. Therefore, many mid-size cars take full advantage of this feature in their safety design. 2. Upgraded version: By utilizing hood pop-up technology, the engine is instantly raised during a collision, ensuring that the human body does not hit the hard car shell but rather a soft and smooth surface. Upon detecting a pedestrian collision, the vehicle automatically activates the hood pop-up control module, and the built-in ejection device can instantly lift the engine hood, effectively placing an air cushion beneath the falling person.
When the pedestrian protection system is triggered, based on my experience, it usually requires replacing several core components, mainly the hood assembly and related sensors. The system may activate if the vehicle hits an obstacle, causing the hood to pop up to cushion the impact and protect pedestrians. Once triggered, these components become inoperative and must be fully replaced; otherwise, the safety function may fail, affecting future use. For example, after detecting a collision, the sensors send a signal, and the pop-up section contains one-time-use materials that cannot be simply repaired. I recommend immediately contacting a professional repair shop for inspection—they will handle the replacement. The cost may be high, but insurance can help reduce the burden. Additionally, after triggering, pay attention to the vehicle's condition. When driving to the repair shop, avoid speeding to ensure safety comes first. Developing habits to avoid collisions can save you from these troubles.
