Installation Guide

Professional installation is recommended for optimal performance and safety. Ensure the vehicle's power is off before beginning installation.

1. Planning Sensor Placement

Determine the optimal locations on the rear bumper for the four ultrasonic sensors. Ensure they are evenly spaced and at a consistent height, typically between 50-70 cm from the ground.
Avoid placing sensors directly behind metal structures or exhaust pipes that could interfere with their operation.

2. Sensor Mounting

Use the provided drill bit (if applicable) to create holes in the bumper at the marked locations.
Carefully insert each sensor into its respective hole, ensuring a snug fit. The sensors should be flush with the bumper surface.
Route the sensor cables through the bumper and into the vehicle's interior, typically through existing grommets or carefully drilled access points.

3. Control Box and Buzzer Placement

Find a secure, dry location inside the vehicle's trunk or cabin for the main control box. Ensure it is away from heat sources and moisture.
Mount the buzzer in a location where its sound can be clearly heard by the driver, such as near the dashboard or rear shelf.

4. Wiring Connections

Connect each sensor cable to the corresponding port on the main control box (usually labeled A, B, C, D).
Connect the buzzer cable to the designated port on the control box.
Connect the power cable to the vehicle's reverse light circuit. This ensures the system activates automatically when the vehicle is put into reverse. Connect the positive wire to the reverse light's positive terminal and the negative wire to a chassis ground point.
Secure all wiring to prevent pinching or damage.

5. System Test

Once all connections are made, turn on the vehicle's ignition and engage reverse gear.
Walk behind the vehicle, approaching the sensors from different angles. The buzzer should emit a series of beeps, increasing in frequency as you get closer to the sensors.
Verify that all sensors are detecting obstacles correctly and that the alarm functions as described in the operation section.

Operating Instructions

The Tiiyee Car Reverse Backup Parking Sensor Radar System operates automatically when the vehicle is in reverse gear.

Activation: The system activates automatically when the vehicle's reverse gear is engaged.
Distance Detection: The ultrasonic sensors emit waves to detect obstacles within their range (30 cm to 150 cm) behind the vehicle.
Audible Alerts:
- As an obstacle is detected, the buzzer will emit a series of "Bi.Bi.Bi." sounds.
- The frequency of the beeps increases as the vehicle gets closer to the obstacle.
- A continuous "Biiiiii" sound typically indicates a very close proximity to an obstacle, usually within 30 cm.
Self-Test Function: The system continuously monitors the status of its sensors. If a sensor is damaged or malfunctioning, the system may provide an alert to indicate an abnormal state, preventing false confidence during reversing.

Maintenance

To ensure the longevity and reliable performance of your parking sensor system, follow these maintenance guidelines:

Sensor Cleaning: Regularly clean the surface of the ultrasonic sensors on the bumper. Dirt, mud, snow, or ice can obstruct the sensors and affect their accuracy. Use a soft cloth and mild cleaning solution.
Cable Inspection: Periodically check all visible cables for any signs of wear, fraying, or damage. Ensure all connections remain secure.
Avoid High-Pressure Washing: When washing your vehicle, avoid directing high-pressure water jets directly at the sensors, as this could potentially damage them.
Environmental Factors: Be aware that extreme weather conditions (heavy rain, thick fog, snow) can temporarily affect sensor performance.

Troubleshooting

If you encounter issues with your Tiiyee Car Reverse Backup Parking Sensor Radar System, refer to the following common problems and solutions:

Problem	Possible Cause	Solution
System does not activate when reversing.	No power to the control box. Incorrect wiring to the reverse light circuit. Blown fuse in the vehicle's reverse light circuit.	Check power connections to the control box. Verify wiring to the reverse light. Inspect and replace any blown fuses.
No alarm sound or weak alarm.	Buzzer cable disconnected or damaged. Buzzer malfunction.	Check the buzzer connection to the control box. Test the buzzer if possible; replace if faulty.
Continuous alarm or false alarms.	Sensors are dirty or obstructed. Sensor malfunction or damage. Incorrect sensor installation (e.g., angled towards the ground).	Clean sensors thoroughly. Inspect sensors for physical damage. Verify sensor orientation and mounting.
Inaccurate distance detection.	Sensors are dirty or obstructed. Interference from other vehicle components. Sensor malfunction.	Clean sensors. Ensure no objects are blocking the sensor's field of view. If problem persists, a sensor may need replacement.
