Solution

1. Preparation

Gather required tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.

2. Inspect and Clean Sensors

Locate the parking sensors (typically mounted in the front and rear bumpers).
Clean each sensor with a soft cloth and mild detergent to remove dirt or debris.
Visually inspect each sensor for cracks or damage; replace any damaged sensors.

3. Check Wiring and Connections

Remove the bumper if necessary to access the wiring harness (refer to vehicle service manual for specifics).
Inspect the wiring harness for signs of wear, corrosion, or disconnection.
Repair or replace any damaged wiring or connectors.

4. Test Sensor Operation

Reconnect the battery.
Use the OBD-II scanner to clear any error codes.
Test the sensors by placing an object near the sensors while the vehicle is in reverse to check for proper operation.

5. Replace Control Module (if necessary)

If the sensors and wiring are functional, consider replacing the parking sensor control module.
Disconnect the battery and remove the module (typically located under the dashboard or in the trunk).
Install the new control module and reconnect the battery.
