Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to avoid any electrical shorts during repair.

2. Inspect and Clean Sensors

Tools Required: Soft cloth, cleaning solution
Inspect each parking sensor for dirt or debris.
Clean the sensor surfaces with a soft cloth and an appropriate cleaning solution.

3. Repair or Replace Damaged Components

Tools Required: Socket set, multimeter
If any wiring or connectors are damaged, cut away the damaged section and splice in new wiring or connectors.
If a sensor is faulty, remove it by unbolting or unclipping it from its mount.
Replace with a new sensor, ensuring it is securely attached.

4. Test the Control Module and Wiring

Tools Required: Multimeter, OBD-II scanner
Reconnect any connectors and wiring that were previously disconnected.
Ensure the control module is receiving power by checking the voltage at its connector.
If the module is faulty, replace it following the manufacturer's guidelines.

5. Reassemble and Final Checks

Reconnect the battery terminal.
Reassemble any components removed during the repair process.
Clear any fault codes using the OBD-II scanner.
