Is it necessary to go to a 4S shop for ACC calibration?

ACC calibration does not necessarily require going to a 4S shop, as regular repair shops can also perform the task. Below is a detailed introduction about ACC calibration: Introduction: Adaptive Cruise Control, abbreviated as ACC, is an electronic control system that builds upon the vehicle's cruise control system by adding radar waves projected directly forward from the front of the car. The radar sensor is installed behind the bumper cover at the position of the cooling vents, providing a clear forward detection field for the radar waves. Function: ACC is currently an intelligent automatic control product that adjusts the vehicle's speed based on the driver's preset speed and data feedback from the radar, maintaining a safe distance from obstacles and significantly reducing the driver's burden. However, due to cost constraints, this system is generally found in higher-priced vehicle models.
As an experienced long-term car owner, I don't think ACC calibration must be done at a 4S shop. Many professional auto repair shops can also perform calibration as long as they have the proper equipment and software. The ACC system typically requires adjustment of radar or camera sensors, especially after an accident or when components are replaced. I tried an independent repair center last time, which cost about 40% less than a 4S shop, and the ACC worked perfectly after calibration. However, the advantage of 4S shops is their OEM support and parts quality, ensuring greater precision. That said, many independent shops now have OBD scanners and calibration tools, making the process highly efficient. The key is to choose a qualified and well-reviewed place to avoid errors that could cause system failure. Safety always comes first, so I personally check the shop's qualifications and track record before deciding. In short, there are multiple options, but reliability should be the priority.
