In today’s vehicles, technology plays a bigger role than ever before. Features like lane departure warnings, blind-spot monitoring, adaptive cruise control, and automatic emergency braking have become common. These systems rely on sensors, cameras, and radar to work correctly. After a collision, even if the damage seems minor, it’s important to recalibrate these systems to make sure they’re functioning properly. Calibration is essential in modern collision repairs to ensure your car’s safety features are accurate and reliable.
Let’s break down why calibration is so important and what it involves.
What is Calibration?
Calibration refers to the process of resetting and adjusting your vehicle’s sensors, cameras, and other electronic components to their original factory settings. After a collision, these sensors and cameras may be misaligned or damaged, even if the impact wasn’t severe. Without proper calibration, the systems that rely on these devices may not work as they should, which can affect your safety.
For example, if your car’s front camera is out of alignment, the lane-keeping assist feature may fail to alert you when you drift out of your lane. This could lead to a dangerous situation, especially at high speeds.
Why Is Calibration Necessary After a Collision?
Modern cars are equipped with what’s known as ADAS (Advanced Driver Assistance Systems). These systems depend on the accurate placement and function of various sensors and cameras located around the vehicle. After an accident, even a minor fender bender, the alignment of these devices can shift. This can cause the ADAS features to malfunction or give incorrect information.
When calibration is necessary:
Windshield Replacement: If your windshield is replaced, the front-facing camera mounted on the windshield needs to be recalibrated.
Bumper Damage: Many cars have sensors for parking assistance and collision warnings in the front and rear bumpers. After a bumper repair or replacement, calibration ensures these sensors are aligned and functioning properly.
Suspension or Wheel Alignment: Even minor impacts can throw off your vehicle’s alignment, which in turn affects systems like lane departure warning and adaptive cruise control. Calibration after suspension or alignment work is often needed.
Airbag Deployment: In some cases, airbags are connected to systems that require recalibration after being deployed in an accident.
The Calibration Process
The process of calibration typically involves two main types: static calibration and dynamic calibration.
Static Calibration: This is done in a controlled environment, like a repair shop. The vehicle is placed on a level surface, and special equipment, such as calibration targets, is used to adjust the cameras and sensors to their factory settings. This type of calibration doesn’t require the car to be driven.
Dynamic Calibration: This is done while driving the vehicle. During the calibration process, the vehicle is taken for a road test, and the sensors and cameras are adjusted as the car moves. The car’s onboard computer receives data from the sensors and makes necessary adjustments.
Both types of calibration are important depending on the vehicle’s make and model. Some cars need both static and dynamic calibration to ensure all systems are working properly.
The Importance of Using Certified Technicians
Calibration isn’t something that just any repair shop can handle. It requires specialized equipment and trained technicians who understand how to properly adjust and reset the advanced systems in modern vehicles. A shop that is certified by organizations like ASE (Automotive Service Excellence) or I-CAR (Inter-Industry Conference on Auto Collision Repair) will have the right tools and knowledge to perform proper calibration.
What to ask: When choosing a repair shop, ask if they have the equipment and training necessary to perform calibration. Not every shop has this capability, so it’s important to find one that does to ensure your car’s systems are accurately restored.
Risks of Skipping Calibration
Skipping calibration after a collision can lead to serious risks, both for you and others on the road. ADAS features are designed to help prevent accidents, and if they’re not working correctly, you could find yourself in a dangerous situation. For example:
Incorrect Blind-Spot Monitoring: If the sensors for your blind-spot monitoring system are not calibrated, the system may fail to alert you when a car is in your blind spot, increasing the risk of an accident.
Faulty Collision Warnings: A misaligned front camera can cause false collision warnings or, worse, fail to alert you when a collision is actually imminent.
Without proper calibration, these systems may not work as intended, which could compromise your safety on the road.
How to Ensure Calibration Is Done Correctly
To make sure your vehicle’s calibration is done right, follow these steps:
Choose the Right Repair Shop: As mentioned earlier, not all repair shops are equipped to handle calibration. Be sure to choose a shop with certified technicians and the necessary tools.
Ask for Proof of Calibration: After the repairs are complete, ask the shop for documentation that shows the calibration was performed. This should include details about the systems that were calibrated and any tests that were done.
Test the Systems Yourself: After getting your car back, take some time to test the ADAS features. Try out the lane departure warning, adaptive cruise control, and any other systems your car has. Make sure they’re working correctly before you resume regular driving.
Conclusion
Calibration plays a critical role in modern collision repairs. Without it, the advanced safety systems in your vehicle may not work properly, putting you at risk. After a collision, it’s essential to ensure that your car’s sensors, cameras, and other ADAS components are properly calibrated by a certified technician. By choosing a reputable repair shop and following the steps outlined in this article, you can make sure your vehicle is safe and ready to get back on the road.
