What is blind spot calibration?

Blind spot calibration is the process of calibrating the BSM sensors on the vehicle to ensure they can accurately detect and promptly alert the driver of any obstacles in the vehicle's blind spot.

Why need blind spot monitor calibration?

In real driving, the blind spot refers to an area around the vehicle that a driver cannot see. Blind spot monitors are safety features installed in vehicles. These monitors use sensors to detect the presence of other vehicles in the driver's blind spot, then provide a warning to the driver.

Calibrating blind spot monitors is important to ensure they function properly and accurately detect other vehicles, which is an important aspect of vehicle safety. If the blind spot monitor is not properly calibrated, other vehicles in the blind spot may not be detected, or false alerts may be provided. This distracts the driver and may even lead to an accident.

How does blind spot monitoring work?

So, how does blind spot monitoring work? Let's learn more about it!

Blind spot monitoring systems typically utilize sensors mounted in the side mirrors or rear bumper to detect other vehicles in the blind spot. These sensors use radar or sonar technology to determine the distance and speed of other vehicles.

When the vehicle enters a blind spot, the sensor sends a signal to the system's control module, which then activates a warning signal to alert the driver. Warnings can be in the form of visual alerts, such as lights in side mirrors or on the dashboard, or audible alerts, such as beeps or chimes.

Some systems also use cameras or other advanced technology to provide additional information to the driver, such as a live video feed of blind spots.

How to calibrate blind spot monitor?

Calibrating a blind spot monitor (BSM) usually involves the combination of resetting the system, checking sensors, and making sure the system is functioning properly. It is best to have a professional operate the calibration. The exact steps for calibrating a blind spot monitor may vary by vehicle brand and model, so it's important to refer to your vehicle's manual for more detailed instructions. Here, we just briefly describe the general steps that can be followed.

Here are some general steps to follow:

  • Place the vehicle in the specified environment and turn off the engine.
  • Find out the blind spot monitoring sensors on the vehicle.
  • Inspect the sensor for any damage or debris that may be blocking its line of sight. Clean the sensor if necessary.
  • Check that the BSM system is turned on and functioning properly.
  • Reset the BSM system. This can usually be done by disconnecting the vehicle battery for a few minutes, then reconnecting it.
  • Test the BSM system by driving your vehicle in a safe and controlled environment such as an empty parking lot. When you are approaching another vehicle, pay attention to the BSM warning light and make sure it activates when another vehicle is in your blind spot.

If the BSM system still does not work properly, take your vehicle to a certified repair shop or dealer for the system to be checked and calibrated.

What kinds of blind spot monitor calibration tools?

Performing calibration often requires specialized tools, blind spot monitor calibration tools probably including:

  • ADAS calibration tools: for example X-431 ADAS PRO PLUS, X-431 ADAS Mobile, X-431 ADAS LITE.
  • ADAS targets: specified ADAS targets are used to align radar sensors and camera systems to ensure they are accurately aimed at the correct location.
  • Diagnostic scan tools: this tool is used to access the vehicle's onboard diagnostic system and retrieve any fault codes related to the blind spot monitoring system.
  • Calibration software: calibration software is used to initiate the calibration process and adjust the blind spot monitoring system as needed to ensure proper operation.

If you're starting a repair shop, you can get the above tools directly from your dealer. But for all specific tools, I suggest that you must ask the dealer!

How long does it take to calibrate blind spot sensors?

You must be curious about this question. It is related to how you allocate your time! In fact, how long it takes to calibrate blind spot sensors depends on the following factors:

  • Brand and model of vehicle
  • Sensor type
  • Calibration method

Typically, the calibration process can take from a few minutes to over an hour or more. Because some blind-spot sensors can calibrate themselves and automatically adapt to their surroundings after a short drive. Other sensors may require manual calibration using special equipment and software.

If you're unsure about your vehicle and the blind spot sensor calibration process, it's best to consult your auto's manual or contact a professional calibrator or dealer for guidance. They can give you the most accurate information and help ensure your blind spot sensors are calibrated and functioning properly.

How much does it cost to calibrate blind spot monitors?

Of course, the cost is also our biggest concern! There are also many factors that affect the cost of calibrating blind spot monitors, including the brand and model of the vehicle, calibration method, where the repair center is located, and the extent of the calibration required. Typically, the fee can range from $50 to $400, or more. Some service providers may charge a flat fee for calibration, while others may charge by the hour. Also, some vehicles may require more extensive calibration, which adds to the cost.

We have to take the cost into account, but compared with our own safety, it seems to be less important.

In conclusion, calibrating your blind spot monitor has a huge impact on your safety and the safety of other road users. We should follow the manufacturer's calibration guidelines or have a professional perform the calibration to ensure accurate and reliable results.
