Why ADAS Calibration After a Collision Is Non-Negotiable

Your car has more cameras and radar sensors than ever, and they all need to point exactly where the factory aimed them. Move a bumper a millimeter, replace a windshield, or repair a fender — and those sensors are now lying to the car's computer. ADAS calibration brings them back into spec.

What ADAS Actually Does Advanced Driver Assistance Systems include: - Adaptive cruise control - Automatic emergency braking - Lane departure warning and lane keep assist - Blind spot monitoring - Forward collision warning - 360-degree cameras

Each feature depends on cameras, radar, lidar, or ultrasonic sensors mounted around the vehicle. After a collision, these sensors are often physically moved or their mounting surface is altered.

Static vs. Dynamic Calibration **Static calibration** is done in the shop with manufacturer-specific targets placed at exact distances and heights. The vehicle must be on a level floor, at the correct ride height, with proper lighting.

**Dynamic calibration** is performed on the road at specific speeds, on clearly marked lanes, with the scan tool actively communicating with the vehicle.

Most cars need both.

Why It Matters A windshield replaced without camera recalibration can cause lane keep assist to gently steer you into oncoming traffic. A bumper replaced without radar recalibration can leave adaptive cruise unable to detect a stopped car in front of you. These are not theoretical risks.

What to Ask Your Shop - Do you perform ADAS calibration in-house or sublet it? - Do you use OEM scan tools or aftermarket equivalents? - Will I get printed proof of calibration?

If the answers are vague, walk away. Calibration documentation should be part of your final paperwork.
