After the technician finishes preparing, setting up the equipment is their next step. They use specific tools and devices for this part of the process. This ensures that all advanced driver assistance systems work as they should after replacing a windshield.

The technician should follow manufacturer guidelines to set up the equipment. Each system might require different setups to test steering control or speed limit recognition properly.

The tech will want to make sure they have all the necessary information about your vehicle’s model and type before starting because some may have
unique requirements listed under a specific RPO code found near the rearview mirror or suspension parts area.

Calibration Process

The calibration process starts with setting up the right tools and equipment. Technicians use specific machinery designed for ADAS to ensure everything is precise. They will likely follow a checklist to prepare the vehicle, making sure it’s in the correct position and environment for calibrating advanced driver assistance systems.

This preparation is crucial for accurate results.

Next, experts carry out the actual calibration tasks. This involves adjusting various components of the vehicle’s assistance systems to ensure they work as intended. For dynamic calibration, this might mean taking the car on a road test under certain conditions to tune its systems properly.

The goal here is not just about meeting standards but ensuring that each part of the system communicates correctly with others for optimal performance and safety on roads bustling with traffic and varying speed limits.

Post-Calibration Checks

After completing the calibration process, the tech may perform a thorough examination of all ADAS components to ensure proper functionality; double-checking the position and condition of all sensors, ensuring they are securely attached without any damage or obstruction from dirt or debris.

They can also use diagnostic tools to verify that each system is communicating effectively and accurately interpreting data. Conducting road tests to confirm that all ADAS features, such as lane departure warning systems and automated braking, are operating as intended in real-world driving scenarios is the final step.

It’s crucial for technicians to meticulously inspect the vehicle post-calibration to guarantee that advanced driver assistance systems are functioning reliably. Regular verification checks play a fundamental role in maintaining safety and performance standards across vehicles equipped with embedded ADAS technology.

  1. My ADAS fell off the windshield due to the sun. Everyone I call to have it recalibrated try’s to tell me I have to replace the windshield . There is no logic reason to me other than there are just trying to make more money. Can the ADAS be recalibrated without buying a new windshield?

    1. Hi Renee,
      Thanks for the question. Without seeing the vehicle in person it’s difficult to say. it’s possible that either:
      1. The mount cannot be re-attached and the only way to obtain an attachment is with an new windshield.
      2. The area of the windshield where the ADAS attaches is damaged.
      Some mounts are integrated into the windshield in very specific ways. The shops that you spoke with likely want to do whatever is necessary to ensure the ADAS equipment doesn’t detach again, creating a safety hazard.
