ADAS & Current Vehicle Technologies

For vehicles featuring ADAS systems, technicians need to perform both dynamic and static calibration to guarantee accurate system diagnostics for cameras and radar units.

Maintain awareness of the latest programming and software updates to preserve proper functioning of safety systems and adhere to warranty requirements.

Comprehensive logging of calibration steps remains critical for warranty compliance and proper safety system verification.

Dynamic vs Static Calibration Methods

An essential element of Advanced Driver Assistance Systems (ADAS) is guaranteeing precise calibration, which can be accomplished through two main methods.

Static calibration takes place with the vehicle stationary, often in a specialized workspace like a workshop. You'll need a level surface, controlled lighting, and specific calibration equipment. This technique delivers high precision, but it demands a designated area and can be time-consuming. It's more rigid and requires substantial facility costs but guarantees reliable outcomes, not influenced by weather.

In contrast, dynamic calibration procedures, or on-road calibration, takes place while the vehicle is in motion. This method demands clear weather, clear road lines, and specific driving speeds. You'll benefit from its flexibility, as it assesses the system in real-world conditions and requires less dedicated tools. However, it relies significantly on weather and road conditions, and the results can vary.

Choosing between these methods hinges on specific vehicle needs, manufacturer specifications, and your workshop's resources. Often, both calibrations are required to maintain ideal ADAS performance, specifically after services like windscreen changes or wheel balancing.

Each approach demands technical knowledge 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 optimal performance.

Start by conducting examining sensors visually for obstructions and physical damage. You must retrieve any stored fault codes that may indicate operational issues or alignment concerns. Check each component's positioning following factory guidelines.
