Maintain awareness of the latest programming and software updates to maintain proper functioning of safety systems and comply with warranty requirements.

Comprehensive logging of these procedures is essential for meeting warranty requirements and effective safety system verification.

Dynamic vs Static Calibration Methods

A key component of ADAS technology is maintaining precise calibration, which is achieved through two main methods.

The static calibration process is conducted with the vehicle stationary, often in a specialized workspace like a workshop. You'll need a level floor, proper illumination, and specific calibration equipment. This technique delivers high precision, but it demands a designated area and tends to be time-consuming. It's less adaptable and incurs higher facility costs but delivers consistent results, independent of weather.

On the other hand, dynamic calibration procedures, or on-road calibration, occurs while the vehicle is being driven. This method demands clear weather, visible road markings, and particular vehicle velocities. The advantage lies in its flexibility, as it tests the system in actual driving situations and needs less specific hardware. However, it is greatly influenced by weather and road conditions, and the outcomes may fluctuate.

Selecting from these methods depends on vehicle requirements, manufacturer requirements, and your facility's capabilities. In many cases, both calibrations are necessary to guarantee ideal ADAS performance, particularly after services like glass installations or wheel balancing.

Each approach needs technical knowledge and needs to be approached with precision to maintain system integrity.

ADAS Camera and Radar Diagnostics

Modern ADAS vehicles require careful diagnostic procedures for sensing systems to guarantee reliable functionality.

Begin with checking all sensors to identify any blockages or damage. You must retrieve any stored fault codes which could reveal system malfunctions or misalignment. Check each component's positioning based on OEM requirements.
