Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, cleaning supplies (mild detergent and cloth).
Ensure the vehicle is parked on a level surface and the engine is off.

2. Clean the Sensors

Use a mild detergent and cloth to gently clean each parking sensor to remove dirt and debris.
Inspect the sensors for physical damage. If any sensor is cracked or damaged, it will need to be replaced.

3. Inspect and Repair Wiring

Remove the rear bumper (if needed) to access wiring harnesses.
Visually inspect the wiring for frays, cuts, or corrosion.
Repair any damaged wires using solder or appropriate connectors, ensuring a secure connection.

4. Test the Parking Sensor Module

Locate the parking sensor module, usually found near the rear of the vehicle.
Use a multimeter to check for voltage at the module. Expected voltage is typically around 12V.
If there is no power, trace the wiring back to the fuse box and check the associated fuse.

5. Replace Faulty Sensors or Module

If any sensors are found to be defective during testing, replace them with OEM parts.
If the parking sensor module is malfunctioning, replace it with a new module, ensuring compatibility with the vehicle's system.
