Detailed recording of these procedures remains critical for meeting warranty requirements and reliable verification of safety systems.

Dynamic vs Static Calibration Methods

A crucial aspect of Advanced Driver Assistance Systems (ADAS) is ensuring precise calibration, which is achieved through two main methods.

The static calibration process takes place with the vehicle immobile, often in a specialized workspace like a workshop. The process demands a flat surface, regulated lighting, and specialized calibration tools. This approach delivers high precision, but it requires a designated area and is often time-consuming. It's less adaptable and incurs higher facility costs but delivers predictable performance, independent of weather.

On the other hand, dynamic calibration procedures, also known as mobile calibration, is performed while the vehicle is moving. This approach needs clear weather, well-defined lane markers, and particular vehicle velocities. You'll benefit from its flexibility, as it tests the system in actual driving situations and needs less specialized equipment. However, it is greatly influenced by weather and road conditions, and the results can vary.

Deciding between these methods is based on vehicle requirements, manufacturer specifications, and your facility's capabilities. In many cases, both calibrations are essential to ensure ideal ADAS performance, particularly after services like windscreen changes or wheel balancing.

Each approach requires professional expertise and must be approached with precision to ensure system integrity.

Camera and Radar System Diagnostics

Modern ADAS vehicles require careful diagnostic procedures for camera and radar systems to ensure reliable functionality.

Begin with examining sensors visually for damage or obstruction. You must check for system error codes that may indicate operational issues or alignment concerns. Verify sensor positioning according to manufacturer specifications.
