Advanced Driver Assistance Systems (ADAS) are in nearly every vehicle built in the last decade — and if your car has been in an accident, windshield replacement, or bumper repair, those systems almost certainly need recalibration. Here's what that means and why it matters.
What Are ADAS Systems?
ADAS is an umbrella term for electronic systems that help drivers avoid accidents. If your vehicle has any of these features, it has ADAS components:
- Forward collision warning / automatic emergency braking
- Adaptive cruise control
- Lane departure warning / lane keeping assist
- Blind spot monitoring
- Rear cross-traffic alert
- 360-degree camera systems
- Parking assist
These systems rely on a network of cameras, radar sensors, lidar, and ultrasonic sensors positioned around the vehicle — often behind the windshield, inside the grille, in the bumpers, and in the side mirrors.
Why Calibration Matters
ADAS sensors need to be pointed at exact angles to function correctly. A forward-facing camera behind your windshield, for example, must be aimed with precision measured in fractions of a degree. A camera that's off by even a small amount can:
- Fail to detect vehicles or pedestrians when it should
- Trigger false warnings or brake the vehicle unnecessarily
- Misjudge lane position and steer incorrectly
- Report incorrect distances to other vehicles
In short: a miscalibrated ADAS system can cause an accident instead of preventing one.
When Does Your Vehicle Need ADAS Calibration?
Many routine repairs can disturb ADAS alignment — even minor ones. Calibration is typically required after:
- Windshield replacement — most forward cameras are mounted to the windshield
- Bumper repair or replacement — radar and ultrasonic sensors are embedded in bumpers
- Collision repair — any impact can shift sensor positions
- Suspension or alignment work — changes in ride height affect camera aim
- Mirror replacement — blind spot sensors are often in the side mirrors
- Certain airbag deployments — impacts severe enough to deploy airbags usually disturb sensors
Static vs Dynamic Calibration
There are two main types of ADAS calibration:
Static calibration is performed in the shop using specialized targets, fixtures, and diagnostic equipment. The vehicle sits on a perfectly level floor at precise distances from calibration targets while the technician uses manufacturer-specific tools to align each sensor.
Dynamic calibration is performed while driving the vehicle under specific conditions — at a set speed, on clearly marked roads, for a set duration. Some systems require only dynamic, some require only static, and many newer vehicles require both.
The correct procedure is determined by the vehicle manufacturer, not the shop. Cutting corners by skipping required calibration steps leaves the system unreliable.
What Happens If ADAS Calibration Is Skipped?
Unfortunately, some shops skip ADAS calibration to save time or cost. This is dangerous because:
- The dashboard may show no warning light even though the system is misaligned
- The system will appear to work normally under most conditions
- The failure often only reveals itself in an emergency — exactly when you need it most
Additionally, skipping required calibration can void your vehicle's warranty and create liability issues if the misaligned system contributes to a future accident.
How to Know If It Was Done Correctly
Ask your body shop:
- Do they perform ADAS calibration in-house or send it out?
- Do they follow OEM (manufacturer) procedures?
- Can they provide documentation showing the calibration was completed?
A reputable shop will provide a printed calibration report confirming each affected system was properly aligned after repair.
ADAS Calibration at Anthony's Touch of Class
Our collision repair process includes proper ADAS calibration for vehicles equipped with these systems. We follow manufacturer-approved procedures to ensure every sensor and camera is recalibrated to factory specifications before your vehicle leaves our shop — because a collision repair that ignores ADAS is an incomplete repair.
