How to Calibrate Windshield?

Posted by Mariios on May 21, 2024

Not sure how to calibrate the windshield properly? You have come to the right place, as we will be discussing everything related to windshield calibration here. 

Calibrating your windshield ensures that the ADAS system in your car works right, helping drivers stay safe. Advanced driver assistance systems (ADAS) use cameras, sensors, and other tech to see obstacles, people, and other cars on the road. However, for these systems to work effectively, they need to be calibrated properly. 

Here is it’s done:

  • Before calibrating the windshield, the technician makes sure the vehicle is on a flat surface with properly inflated tires. They check cameras and sensors for cleanliness and damage. 
  • Then, they connect calibration equipment to the car’s diagnostic port. This equipment talks to the car’s computer to find which ADAS features need calibrating. 
  • They may change the camera mount or angle to make sure everything lines up right.
  • After adjustments, the technician tests the ADAS system to ensure it works. 
  • They might drive the car at a certain speed or direction to check. 
  • Finally, they write down what they did and what tests they did to keep track of the car’s maintenance history.

Windshield calibration is a complex process that requires a trained technician to perform the job correctly. At Blue Diamond Auto Glass, we can help you with all your windshield concerns. Whether it is windshield replacement, repair, or calibration, our technicians are highly trained to perform the job smoothly for you. 

The Process of Windshield Calibration

Here is how the windshields are calibrated:

Step 1: Preparation

First, the technician checks if the car is on a flat surface and if the tires have enough air. Then, they look at the cameras and sensors to make sure they’re clean and not broken.

Step 2: Connection the Calibration Equipment to the Vehicle

The technician will plug the calibration tool into the car’s computer port. This tool talks to the car’s computer to determine which ADAS features need fixing.

Step 3: Alignment

The next step in the windshield calibration process is the alignment. The calibration equipment helps the technician make changes to the cameras and sensors. They adjust things like the camera mount and angle to ensure they’re in the right position, which ensures the system works correctly.

Step 4: Verification Process

After making changes, the technician checks if the ADAS system works as it should. They might drive the car at a certain speed or in a specific direction to test how accurate the system is.

Step 5: Documentation of the Process

Lastly, once the windshield calibration process is done. The technician writes down everything they did during the calibration, like the changes they made and any tests they did. This writing is important because it helps keep track of the car’s maintenance history. It is important to note that it is a complex process that is very difficult to do by yourself if you do not have the right equipment. 

Do windshield wipers need to be calibrated?

No. Windshield wipers do not need to be calibrated. However, you need to calibrate your windshield to ensure it is at the correct angle. This helps prevent your windshield wipers from wearing out quickly. 

How do I know if my windshield needs to be calibrated?

If your vehicle has recently undergone windshield replacement or repair, it must be calibrated. Doing this helps ensure that the vital safety features on your vehicle are working as they should to lower the chances of collision. 

Why is it important to calibrate your windshield?

It’s important to calibrate your windshield to ensure the accurate functioning of your vehicle’s safety features and that the windshield is at the correct angle.


In short, the windshield calibration process involves preparing the vehicle for the technician’s examination of its tyres, cameras, and sensors. Then, the technician connects the calibration equipment to the vehicle’s diagnostic port and determines which ADAS components need calibration. The technicians then perform alignment, verify, and record everything in detail to provide a recorded history.

We at Blue Diamond Auto Glass can help you with the calibration process as we have the right equipment to perform the job right and our technicians are highly experienced and trained in auto glass repair services.
