Experiencing issues with your Blind Spot Monitoring (BSM) system in your Toyota Highlander? It can be concerning when a safety feature you rely on seems to be malfunctioning. Many Toyota Highlander owners have encountered situations where the BSM system appears inactive, leaving them unsure about its operational status. Let’s delve into potential reasons why your BSM might not be available and some initial troubleshooting steps.
Understanding how the BSM system typically functions in a Toyota Highlander is the first step. When activated, usually by a button on the dashboard, a BSM indicator icon should illuminate briefly in your side mirrors. This signals that the system is online and ready to detect vehicles in your blind spots. However, if you’re not seeing this indicator, or if it disappears quickly and doesn’t react to vehicles around you, there might be an issue.
Several factors can lead to a “BSM not available” situation. A simple explanation could be that the system is inadvertently turned off. Locate the BSM button on your dashboard and ensure it is engaged. The button usually has a light to indicate its status. If the light is off, press the button to activate the system and observe if the mirror indicators appear.
Beyond being switched off, sensor obstructions are a common culprit. The BSM system relies on sensors, often located in the rear bumper, to detect vehicles. Dirt, snow, ice, or even bumper stickers directly over the sensor areas can impede their function. Carefully inspect the rear bumper and sensors for any obstructions and clean them if necessary.
Furthermore, system malfunctions, although less frequent, can occur. If basic checks like ensuring the system is turned on and sensors are clear don’t resolve the issue, there might be a deeper technical problem. This could range from a faulty sensor to an issue within the BSM control module.
In conclusion, if your Toyota Highlander displays “BSM not available” symptoms, start with simple checks: verify the system is activated and ensure sensors are unobstructed. If the problem persists after these checks, it’s advisable to seek professional diagnosis. Consulting a certified mechanic or Toyota dealership will help pinpoint the exact cause and implement the necessary repairs to restore your BSM system to proper working order, ensuring your safety on the road.
