Why ADAS Calibration Matters After Collision Repair

Many newer vehicles use Advanced Driver Assistance Systems, commonly called ADAS. Cameras, radar, and sensors may support features such as automatic emergency braking, lane-departure warnings, adaptive cruise control, parking assistance, and blind-spot monitoring.

Why a Collision Can Affect ADAS

Sensors may be mounted behind bumpers, in grilles, on mirrors, or near the windshield. Even when a sensor is not visibly broken, a change in mounting position or vehicle alignment can affect where it is aimed.

Repairs That May Require Calibration

Calibration requirements depend on the vehicle manufacturer and the work performed. Examples can include windshield replacement, bumper or grille repairs, suspension work, wheel alignment, structural repairs, sensor replacement, and removal of certain cameras or radar units.

Static and Dynamic Calibration

Some vehicles require a static calibration using targets and precise measurements inside a controlled work area. Others require a dynamic calibration while the vehicle is driven under specified conditions. Certain vehicles require both procedures.

Why Manufacturer Procedures Matter

Calibration steps, ride-height requirements, tire pressure, alignment specifications, fuel level, and environmental conditions can vary by vehicle. Following the applicable repair information helps determine which scans, inspections, and calibrations are required.

Ask About Scanning and Calibration

Before delivery, ask whether the vehicle was scanned, whether any ADAS components were affected, and whether calibration was required and completed. Documentation should match the operations performed on the vehicle.
