Detailed recording of these procedures remains critical for meeting warranty requirements and effective safety system verification.

Static vs Dynamic Calibration Methods

A key component of Advanced Driver Assistance Systems (ADAS) is maintaining precise calibration, which is performed through either static or dynamic methods.

The static calibration process is conducted with the vehicle immobile, usually in a controlled environment like a workshop. You'll need a level floor, controlled lighting, and specific calibration equipment. This technique offers high precision, but it requires a designated area and tends to be time-consuming. It's less flexible and incurs higher facility costs but delivers predictable performance, not influenced by weather.

In contrast, the dynamic method, or mobile calibration, takes place while the vehicle is moving. This process demands clear weather, clear road lines, and specific driving speeds. You'll benefit from its flexibility, as it tests the system in practical scenarios and requires less specialized equipment. However, it depends heavily on weather and road conditions, and the outcomes may fluctuate.

Selecting from these methods is based on automotive specifications, manufacturer specifications, and your facility's capabilities. Often, both calibrations are essential to ensure ideal ADAS performance, particularly after services like windshield replacements or wheel alignments.

Each method requires specialized skills and should be approached with precision to maintain system integrity.

Diagnostic Procedures for Camera and Radar Systems

Modern ADAS vehicles require a meticulous approach to diagnosing camera and radar systems to ensure optimal performance.
