Thorough documentation of these processes is crucial for meeting warranty requirements and reliable verification of safety systems.

Static vs Dynamic Calibration Methods

A key component of driver assistance systems is maintaining precise calibration, which is performed through two main methods.

Static calibration procedures is performed with the vehicle immobile, typically in a specialized workspace like a workshop. The process demands a level floor, proper illumination, and specific calibration equipment. This approach provides high precision, but it necessitates a designated area and tends to be time-consuming. It's more rigid and requires substantial facility costs but guarantees reliable outcomes, not influenced by weather.

On the other hand, dynamic calibration procedures, or on-road calibration, is performed while the vehicle is being driven. This approach demands clear weather, visible road markings, and specific driving speeds. This method offers its flexibility, as it assesses the system in actual driving situations and demands less dedicated tools. However, it is greatly influenced by weather and road conditions, and the results can vary.

Choosing between these methods is based on automotive specifications, OEM guidelines, and your workshop's resources. In many cases, both calibrations are required to ensure ideal ADAS performance, specifically after services like windshield replacements or alignment services.

Each technique needs professional expertise and should be approached with precision to ensure system integrity.

ADAS Camera and Radar Diagnostics

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

Start by conducting a visual inspection of sensors to identify any blockages or damage. You must check for system error codes that may indicate component issues or positioning problems. Check the placement of all components following factory guidelines.
