Subaru ADAS recalibration after windshield replacement is commonly required when a windshield-mounted camera runs safety features like Lane Keeping Assist, Forward Collision Warning, Automatic Emergency Braking (AEB), traffic sign recognition, and portions of Adaptive Cruise Control (ACC). The reason is tolerance: removing and reinstalling the windshield can change the camera's relationship to the road by millimeters, and the software is designed around tight specifications. Calibration restores that relationship to factory targets so lane guidance, warnings, and braking interventions occur at the correct time and distance. Depending on the Subaru model and sensor package, calibration may be static, dynamic, or both. Static calibration uses manufacturer targets, precise measurements, level flooring, and controlled lighting. Dynamic calibration uses a defined on-road drive cycle so the system can relearn lane lines and reference points in real traffic, usually in good weather on well-marked roads. In either case, a scan tool is used to check diagnostic trouble codes (DTCs), confirm module communication, and document completion. At Bang AutoGlass, we set expectations up front and coordinate the proper recalibration path so your ADAS works the way it was designed. If you are using insurance, we work with all insurance companies when your policy includes comprehensive coverage.
