When evaluating a vehicle for ADAS recalibration after windshield change, which components are typically checked?

• A. Engine control unit and braking system.
• B. Camera, radar, lane-keeping sensors, and mounting brackets or reflectors that influence alignment.
• C. Brakes and tires.
• D. Windshield tint and defroster performance.

Answer: (B)

ADAS recalibration after windshield replacement centers on sensor alignment. The key sensors that rely on the windshield as a reference—the camera, radar, and lane-keeping sensors—must be checked to ensure they’re positioned correctly and functioning within specification. Any shift in their location, even small, can bias readings and degrade performance, so technicians verify each sensor’s alignment and perform recalibration if needed. The mounting brackets or reflectors that influence how those sensors are held and aimed are also inspected because they establish the exact geometry relative to the vehicle and the road ahead.

Other systems like the engine control unit and braking system operate independently of ADAS sensor calibration, so they’re not part of the recalibration process. Brakes and tires affect overall vehicle performance but not the sensor alignment used by ADAS. Windshield tint and defroster performance don’t impact sensor calibration either.
