Hyundai Blind Spot Detection System Not Working (FIXED)

Driving a Hyundai vehicle comes with various technological features, including the blind spot detection system. This advanced safety feature is designed to alert you of vehicles in your blind spots, making lane changes and merges smoother and safer. However, like any technology, it might encounter some issues that could stop it from working correctly.

When your Hyundai’s blind spot detection system fails, it’s essential to know what steps to take in order to diagnose and fix the problem. In this article, we’ll discuss common causes of malfunction and provide solutions to ensure your safety while driving.

What is Hyundai Blind Spot Detection System

The Hyundai Blind Spot Detection System (BSD) is an essential safety feature in your vehicle that helps increase your awareness of surrounding traffic. In this section, we will cover the key components of the system, as well as its safety and convenience aspects.

Blind Spot Detection Components

The BSD system consists of several components, such as sensors located on the left and right side of your vehicle. These sensors monitor your blind spots and provide alerts if another vehicle or object is detected. The system also includes a BSD module responsible for processing sensor data and sending alerts to the driver.

It’s crucial to maintain these components and follow the recommended calibration steps if you have recently replaced or serviced any part of the system. Proper calibration ensures optimal performance and helps prevent missing calibration issues.

Safety and Convenience

Hyundai’s blind spot detection system contributes to both safety and convenience while driving. When traveling over 20 mph, the BSD system senses the rear side territory of your vehicle and alerts you when a vehicle is detected in your blind spot. This can be particularly helpful when changing lanes on a highway where the high speed of traffic might make it difficult to detect vehicles manually.

Keep in mind that the system does have limitations, as it might not detect all vehicles or objects in the blind spot. However, it is still a valuable tool that aids in accident prevention and ensures a safer driving experience. Additionally, Hyundai offers a limited warranty covering the BSD system to address any potential issues and provide peace of mind.

Remember, it’s essential to keep your VIN handy when seeking service for your Hyundai blind spot detection system. Proper care and maintenance of the system’s components, as well as regular calibration, will ensure it continues to support your safety and convenience on the road.

Common Issues and Solutions

Faulty or Damaged Sensors

Faulty or damaged sensors are a common cause of Hyundai’s blind spot detection system not working. First, inspect the sensors located in your bumpers and side mirrors for any visible damage, such as dents or scratches. If you find any damage, you may need to replace the affected sensors. If there’s no visible damage, you can use a detection tool to check the sensors’ functionality. In some cases, bumpers and side mirrors may also require adjustment.

Calibration Problems

Sometimes, your Hyundai blind spot detection system might need a recalibration. This can happen after replacing sensors or making adjustments related to the system. To calibrate, use a detection tool and follow the system test called “Blind Spot Detection Calibration,” which can be found in your BSD module. Turn on the ignition and connect your detection tool. Perform the test on the left side first. In some cases, calibration may need to be performed by a professional mechanic.

Error Codes and Troubleshooting

If your Hyundai blind spot detection system is not working, it might display error codes on your dashboard. These codes, also known as Diagnostic Trouble Codes (DTCs), can help identify the issue. First, cycle your ignition and check for any DTCs using a detection tool or consult your vehicle’s owner’s manual for guidance. You can then use this information to troubleshoot specific issues:

  • Check continuity between CAN lines between two BSD modules using a multimeter.
  • Inspect wire harnesses for any signs of wear, tear, or poor connection.
  • Examine connector pins for damage, tension, corrosion, and ensure everything is properly connected.

Keep in mind that some error codes may require the expertise of a professional mechanic to diagnose and resolve.

Remember, by addressing these common issues, you can ensure that your Hyundai blind spot detection system works effectively, keeping you safe on the road.

How to Maintenance and Inspection Hyundai Blind Spot Detection System

Regular Inspection

To ensure your Hyundai’s blind spot detection system works properly, it’s essential to perform regular inspections. Check the sensors for dirt and debris, as these can interfere with their ability to detect nearby vehicles. Gently clean the sensors with a soft cloth to remove any buildup.

Additionally, be mindful of your vehicle’s alerts. If an alert malfunctions or the system does not seem to be working as it should, consult your vehicle’s owner’s manual for troubleshooting tips and guidance on when to seek professional assistance. Remember, the blind spot detection system is a safety feature designed to help you stay aware of your surroundings while driving, so it’s crucial to address any issues promptly.

Dealing with Bumper and Side Mirror Damage

In case your Hyundai experiences bumper or side mirror damage, it’s possible that the blind spot detection sensors could be affected. To ensure the proper functioning of the system, follow these steps:

  1. Inspect the sensors for any damage or debris that may have accumulated during the incident.
  2. Check the side mirror assembly and wire harness for open or shorted wires, frayed connections, or poor fastening. If you find any issues, consult a professional mechanic or your local Hyundai dealership.
  3. Confirm the connectors are fully seated by disconnecting and reconnecting them, and inspect the connector pins for tension, corrosion, or damage.

If any of the sensors or related components are damaged or not functioning correctly, you may need to have them repaired or replaced. Be aware that the blind spot detection system calibration may be necessary after replacing components or working on the system.

Lastly, consult your Hyundai’s warranty information to determine if any repairs or replacements are covered, as warranties may differ depending on your specific model and year.
