Blind spots are a significant hazard on the road, posing a threat to drivers and passengers alike. Aftermarket blind spot monitors (BSMs) offer a practical solution to minimize blind spots and enhance driving safety. This comprehensive guide provides all the necessary information for a successful aftermarket BSM installation.
Materials Required
To install an aftermarket BSM system, you will need the following materials:
- BSM sensors
- Control module
- Display unit
- Wiring harness
- Tools (wrenches, screwdrivers, drill)
Installation Steps
The BSM installation process involves several steps:
1. Mounting the Sensors
Determine the locations of the blind spots on each side of the vehicle. Drill holes and mount the sensors in the desired positions.
2. Installing the Control Module
Place the control module in a central location behind the dashboard and secure it using screws.
3. Connecting the Sensors and Control Module
Use the wiring harness to connect the sensors to the control module and ensure all connections are secure.
4. Mounting the Display Unit
Choose a convenient location on the dashboard for the display unit and mount it using screws or adhesives.
5. Connecting the Display Unit and Control Module
Run the wiring harness from the control module to the display unit and power on the system to check its functionality.
6. Calibration
Start the vehicle and drive at a low speed, turning the steering wheel to both sides. The system will calibrate itself and adjust the blind spot zones.
Benefits of an Aftermarket BSM System
Installing an aftermarket BSM system offers numerous benefits:
- Enhanced safety by reducing blind spot visibility
- Reduced potential for collisions
- Increased driver confidence
- Affordable and convenient solution
Additional Considerations
- Use high-quality components for optimal performance.
- Follow the manufacturer’s instructions carefully for proper installation.
- Test the system thoroughly after installation to ensure correct functioning.
- Consider professional installation if you are not comfortable performing the task yourself.
