Why does my Lexus say check BSM system?
If your Lexus displays a "Check BSM System" warning, it indicates an issue with the Blind Spot Monitoring (BSM) system. The BSM system is designed to detect vehicles in your blind spots and alert you when it's unsafe to change lanes. This warning light suggests a problem with the sensors or the overall BSM system that needs to be addressed.
What is the Blind Spot Monitoring (BSM) System?
The Blind Spot Monitoring (BSM) system is a safety feature found in many modern vehicles, including Lexus models. It uses radar sensors located in the rear bumper to detect vehicles in the driver's blind spots, which are the areas not visible in the side mirrors or rearview mirror. When the BSM system detects a vehicle in your blind spot, it will illuminate an indicator light in the corresponding side mirror, alerting you to the presence of another vehicle and helping to prevent accidents when changing lanes.
Reasons for the "Check BSM System" Warning
There are several potential reasons why your Lexus may display the "Check BSM System" warning:
- Sensor Malfunction: The BSM system relies on radar sensors in the rear bumper to detect vehicles in your blind spots. If one or more of these sensors is malfunctioning, the system will not be able to function properly, triggering the warning light.
- Sensor Obstruction: The BSM sensors can be obstructed by dirt, snow, ice, or other debris, preventing them from accurately detecting vehicles in your blind spots. This can also cause the warning light to illuminate.
- System Failure: In some cases, the BSM system itself may experience a more general failure, leading to the warning light being displayed.
- Software or Electrical Issue: Problems with the vehicle's software or electrical system can also cause the BSM system to malfunction and trigger the warning light.
If you see the "Check BSM System" warning on your Lexus, it's important to have the issue diagnosed and addressed by a qualified technician as soon as possible to ensure your safety and the proper functioning of your vehicle's safety systems.
