4. Setup and Installation

General Installation Steps (Consult a professional):
- Safety First: Ensure the vehicle is turned off and the battery is disconnected before beginning any work.
- Locate Existing Sensor: Identify the faulty PDC sensor on your vehicle's bumper.
- Remove Old Sensor: Carefully disconnect the electrical connector and unclip or unscrew the old sensor from its housing.
- Install New Sensor: Insert the new Aramox PDC sensor into the bumper housing and secure it.
- Connect Electrical Plug: Reconnect the electrical connector to the new sensor. Ensure a secure and tight connection.
- Test Functionality: Reconnect the battery and test the parking assist system according to your vehicle's manufacturer guidelines.

5. Operating Instructions
The PDC Parking Sensor operates automatically when your vehicle is in reverse gear or at low speeds, depending on your vehicle's specific system configuration. It uses ultrasonic waves to detect objects in the sensor's range.
How it Works:
- When activated, the sensors emit ultrasonic pulses.
- These pulses bounce off obstacles and return to the sensor.
- The system calculates the distance to the obstacle based on the time taken for the pulses to return.
- As you approach an obstacle, the system provides an audible warning (beeps) and/or a visual display on your vehicle's infotainment screen, with the frequency of beeps increasing as the distance decreases.
- A continuous tone typically indicates that the vehicle is very close to an obstacle.

6. Maintenance
To ensure the longevity and accurate performance of your Aramox PDC Parking Sensor, follow these simple maintenance guidelines:
- Keep Sensors Clean: Regularly clean the surface of the sensors on your bumper. Dirt, mud, ice, or snow can obstruct the sensor's function and lead to inaccurate readings. Use a soft cloth and mild cleaning solution.
- Avoid Damage: Be careful not to scratch or damage the sensor surface during cleaning or vehicle washing.
- Inspect for Obstructions: Periodically check that no foreign objects (e.g., leaves, debris) are blocking the sensors.
7. Troubleshooting
If you experience issues with your PDC Parking Sensor, consider the following common troubleshooting steps:
- No Warning/Inaccurate Readings:
- Ensure sensors are clean and free from obstructions (dirt, ice, mud).
- Check for any visible damage to the sensor or its wiring.
- Verify that the electrical connector is securely attached to the sensor.
- Constant Warning:
- This could indicate a faulty sensor or a persistent obstruction. Clean the sensors thoroughly.
- If the issue persists, professional diagnosis is recommended.
- System Malfunction Light:
- If your vehicle displays a parking assist system error, it may indicate a sensor failure or a problem with the control unit.
- Consult a professional technician for diagnostic scanning and repair.
For complex issues, it is always best to seek assistance from a certified automotive technician.
