ADAS stands for advanced driver-assistance systems. These technologies use cameras, radar sensors and other equipment to monitor the road and support selected driving and safety functions.

ADAS calibration adjusts or verifies the position and operation of cameras and sensors so they correspond with the vehicle manufacturer’s specified reference points.

ADAS features rely on accurate sensor information. An incorrectly positioned camera or radar unit may misinterpret distances, lane markings or objects around the vehicle.

Calibration may be required following windscreen replacement, collision repair, camera or radar replacement, bumper work, suspension repairs, wheel alignment or other work that affects sensor position or vehicle geometry.

Not every vehicle has a windscreen-mounted ADAS camera. Where one is fitted, the manufacturer’s instructions should be checked to determine whether calibration is required after replacement.

Yes, where calibration is required because of another repair, a warning message, loss of alignment or a manufacturer instruction. The camera and its mounting must be suitable for calibration.

Static calibration takes place while the vehicle is stationary. Precisely positioned targets or reflectors are used with diagnostic equipment according to the manufacturer’s procedure.

Dynamic calibration involves driving the vehicle under specified conditions while the system calibrates using road markings and surrounding information.

The manufacturer determines the required procedure. Some vehicles require static calibration, some require dynamic calibration and others need both.

The time depends on the vehicle, system, preparation required and type of calibration. Dynamic procedures may also be affected by traffic, road and weather conditions.

Yes. Wheel alignment and steering geometry can influence the reference direction used by some ADAS systems. Certain manufacturers require alignment to be checked or corrected before calibration.

They can. Incorrect tyre pressures may affect vehicle height and geometry, so the manufacturer’s preparation requirements should be followed.

Yes, subject to the vehicle and system being supported. Body alignment, sensor mounts, wiring and related repairs should be checked before calibration.

Calibration may be required if the radar sensor or its mounting has been disturbed. The correct procedure depends on the vehicle manufacturer and repair completed.

No. Clearing a diagnostic trouble code is not the same as completing a manufacturer-specified calibration procedure.

No. An ADAS warning may result from obstruction, damaged wiring, sensor failure, an incorrect component, software problems or communication faults. These issues may require diagnosis or repair before calibration.

A failed calibration may indicate incorrect vehicle preparation, wheel-alignment problems, damaged mounting brackets, an unsuitable replacement component, sensor failure or another system fault. Further investigation may be needed.

Where applicable, A1 Diagnostics should provide a calibration report showing the vehicle, system, procedure and outcome. Confirm the available documentation when booking.

A1 Diagnostics can assess suitable light commercial vehicles. Compatibility depends on the vehicle’s size, weight and ADAS equipment.

Yes. A1 Diagnostics supports independent garages, bodyshops, accident repair centres and windscreen companies requiring specialist calibration services.
