1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Torque wrench
Screwdrivers (flathead and Phillips)

2. Inspect and Clean Sensors

Remove any dirt or debris from the parking sensors using a soft cloth.
If any sensors are damaged or cracked, proceed to replace them.

3. Check and Repair Wiring

Inspect the wiring harness connected to the parking sensors for any signs of wear or damage.
- If damaged, carefully splice in new wiring or replace the entire harness.
Ensure all electrical connectors are secure and free from corrosion.

4. Test Control Module

Locate the parking sensor control module, usually found under the dashboard or near the rear of the vehicle.
