Detailed recording of these procedures is crucial for warranty compliance and effective verification of safety systems.

Dynamic vs Static Calibration Methods

A key component of ADAS technology is guaranteeing precise calibration, which can be accomplished through two main methods.

The static calibration process is performed with the vehicle stationary, often in a controlled setting like a workshop. You'll need a level surface, proper illumination, and professional calibration instruments. This technique delivers high precision, but it demands a specialized facility and tends to be time-consuming. It's more rigid and incurs higher facility costs but guarantees consistent results, not influenced by weather.

Alternatively, dynamic calibration procedures, or on-road calibration, is performed while the vehicle is in motion. This process demands clear weather, clear road lines, and controlled driving speeds. The advantage lies in its flexibility, as it tests the system in actual driving situations and needs less dedicated tools. However, it depends heavily on weather and road conditions, and the results can vary.

Selecting from these methods depends on automotive specifications, manufacturer specifications, and your workshop's resources. In many cases, both calibrations are essential to maintain ideal ADAS performance, especially after services like windshield replacements or wheel balancing.

Each technique requires professional expertise and must be approached with precision to maintain system integrity.

Diagnostic Procedures for Camera and Radar Systems

Today's ADAS-equipped vehicles need careful diagnostic procedures for camera and radar systems to ensure flawless operation.

Start by conducting examining sensors visually to identify any blockages or damage. It's crucial to retrieve any stored fault codes pointing to operational issues or alignment concerns. Check sensor positioning according to manufacturer specifications.
