Blind Spot Monitor: Is It Standard On The Toyota Prius?

The Toyota Prius is a popular car model that has been in production since the early 2000s. Over the years, Toyota has introduced various safety features to the Prius, including blind-spot monitoring. Blind-spot monitoring is a system that uses radar to detect and monitor cars on all sides of the vehicle, alerting the driver to any vehicles in their blind spots and helping to prevent accidents when changing lanes or backing out of parking spots. While it is unclear exactly when blind-spot monitoring became available as a feature in the Prius, some sources suggest that it was introduced as an option in 2016 models and became standard in 2017. However, other sources indicate that blind-spot monitoring may have been available as early as 2012 or even 2010, but only in certain markets outside the USA.

Blind spot monitoring available on 2016 and later Toyota Prius models

Blind Spot Monitoring is an innovative safety feature that uses radar technology to detect and monitor vehicles on all sides of a car, alerting the driver to any potential hazards in their blind spots. This advanced system not only assists when driving but also helps prevent accidents while backing out of parking spots, thanks to its rear cross-traffic alert function.

The Toyota Prius, a leader in hybrid vehicle technology, recognised the importance of this feature and made it available on selected models from 2016 onwards. Specifically, the Gen 4, 2016 model and later versions offer this functionality, ensuring enhanced safety and peace of mind for drivers.

While the inclusion of Blind Spot Monitoring varied depending on the trim and option package of the Prius, it became a standard feature on the 2017 model. This meant that drivers could benefit from the added security of this system as a default, without needing to select specific upgrades.

The Blind Spot Monitoring system has proven to be so valuable that it is now a feature that many drivers actively seek out when purchasing a vehicle. Its presence on the 2016 and later Toyota Prius models underscores Toyota's commitment to safety and driver assistance technologies, making their vehicles even more appealing to consumers.

Radar technology used in blind spot monitoring systems

Radar-based blind spot monitoring systems were first introduced by Volvo in its 2007 S80 sedan. These systems use radar technology to alert drivers of vehicles, cyclists, or other obstacles in their blind spots, without the need to check a display. Blind spots refer to the area alongside and just behind a vehicle, which can often be the cause of serious accidents when changing lanes.

Radar-based blind spot monitoring systems typically use a pair of transceivers mounted behind the plastic bumper cover at the back of a car. These transceivers emit a radar frequency signal in a specific pattern and then monitor the area on either side of and behind the vehicle for that signal to be bounced back by an object. When a vehicle or object is detected in the blind spot, an indicator will illuminate to warn the driver, and if a turn signal is activated at the same time, the system will also beep loudly.

Some vehicles, such as certain models of the Toyota Prius, have started to include blind spot monitoring systems as standard or optional features. For example, the 2016 and later models of the Prius offer blind spot monitoring as an option, while the 2017 and later models have it as a standard feature.

Radar-based systems offer some benefits over ultrasonic sensor-based systems. Radar corner sensors have a longer sensing range than ultrasonic sensors, allowing them to detect fast-approaching vehicles at an early stage before a lane change. This helps prevent accidents due to misjudging the speed of approaching vehicles. Additionally, radar-based systems can categorise detected objects by their relevance, preventing false alarms.

Blind spot monitoring system calibration

Blind spots refer to areas around a vehicle that the driver cannot see. Blind spot monitoring systems (BSM) are safety features that use sensors to detect the presence of other vehicles in the driver's blind spot and then provide a warning. These sensors typically use radar or sonar technology, and sometimes cameras, to determine the distance and speed of other vehicles.

Some Toyota Prius models do have blind spot monitoring systems. For example, the 2016 Prius 4 Touring, the 2017 Prius 3, and the 2017 Prius Prime. However, it seems that not all Prius models have this feature, and it may be an optional extra on some models.

Calibration of a BSM is important to ensure the system functions correctly and accurately detects other vehicles, which is essential for safety. If the system is not calibrated properly, it may fail to detect other vehicles in the blind spot or provide false alerts, which could distract the driver and potentially lead to an accident.

Calibration usually involves resetting the system, checking sensors, and ensuring proper functionality. Here is a general step-by-step guide to calibrating a BSM:

• Place the vehicle in a suitable environment and turn off the engine.
• Locate the BSM sensors, typically on the side mirrors or rear bumper.
• Inspect the sensors for any damage or debris that may obstruct their line of sight. Clean if necessary.
• Ensure the BSM system is turned on and functioning.
• Reset the BSM system. This can often be done by disconnecting and then reconnecting the vehicle battery after a few minutes.
• Test the BSM system by driving in a safe, controlled environment, such as an empty parking lot. Pay attention to the BSM warning signals when approaching another vehicle to ensure they activate when a vehicle enters your blind spot.
• If the system still malfunctions, take the vehicle to a certified repair shop or dealer for further inspection and calibration.

It is recommended to refer to the vehicle's manual for specific instructions, as the process may vary depending on the brand and model. Calibration can usually be performed by the vehicle owner or a professional calibrator.

Additional Information

• Calibration tools: ADAS calibration tools, ADAS targets, diagnostic scan tools, and calibration software may be required for the process.
• Time: Calibration can take from a few minutes to over an hour, depending on the vehicle and sensor type.
• Cost: The fee for calibration services can range from $50 to $400 or more, depending on various factors such as the vehicle brand, calibration method, and location.
• Aftermarket BSM: If your vehicle does not have a BSM system, you can consider installing an aftermarket system. These systems can be purchased and installed to provide the benefits of BSM to older vehicles.

Blind spot monitoring control module

The Toyota Prius is a popular car model that has been in production for several years. While it is equipped with many advanced features, there is limited information on whether it has a built-in blind spot monitoring system. One source mentions a 2021 Toyota Prius undergoing a blind spot monitoring system recalibration, but it is unclear if this was an aftermarket addition.

Blind spot monitoring systems are essential safety features for vehicles, and they can be installed aftermarket if your car does not have them built-in. These systems use sensors, cameras, and indicators to alert you of potential hazards in your blind spots, increasing your driving awareness and response time.

If you are specifically looking for information on the blind spot monitoring control module, this is the component responsible for processing information from the sensors and activating the indicators when hazards are detected. When replacing a blind spot monitoring control module, it is important to follow the correct procedure, as outlined in the Mazda CX-5 Service & Repair Manual. The procedure includes the following steps:

• Disconnect the negative battery cable.
• Remove the rear combination light.
• Remove the rear bumper.
• Disconnect the connector.
• Remove the BSM control module.
• Install the new module and reconnect everything in the reverse order of removal.
• Perform the BSM radar test to ensure the system is functioning correctly.

It is important to note that the procedure may vary slightly depending on the specific vehicle and module manufacturer. Always refer to the owner's manual or a certified technician for detailed instructions specific to your vehicle.
