Solution

1. Preparation

Gather required tools: OBD-II scanner, multimeter, soft cloth, and socket set.
Ensure the vehicle is turned off and parked in a safe area.

2. Clean Sensor Lenses

Use a soft, damp cloth to gently clean each parking sensor lens.
Avoid using abrasive materials that could scratch the sensors.

3. Inspect and Repair Wiring

Remove the rear bumper cover if necessary to access the wiring harness connected to the parking sensors.
Check each wiring harness for signs of wear, corrosion, or disconnection. Repair any damaged wiring or connectors.
Reconnect any loose connections ensuring a secure fit.

4. Replace Faulty Sensors (if applicable)

If testing reveals that a sensor is non-functional, remove the faulty sensor by unscrewing it from its mount.
Install the new sensor by reversing the removal process, ensuring it is secured properly.
Connect the wiring harness to the new sensor.

5. Reassemble and Test

Reattach the bumper cover if it was removed.
Turn on the vehicle and perform a system check to ensure the sensors are operational.
Test the parking sensor functionality by engaging the system and checking for accuracy in alerts and readings.
