Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, cleaning cloth.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Clean Sensors

Locate the parking sensors on the front and rear bumpers.
Use a cleaning cloth and mild soap solution to gently clean each sensor.
Ensure that no dirt, snow, or ice is obstructing the sensors.

3. Check Wiring and Connectors

Reconnect the vehicle battery.
Access the wiring harness connected to the parking sensors.
Visually inspect for any damaged wires or loose connections.
If necessary, repair or replace damaged connectors or wiring.

4. Replace Blown Fuse

Locate the fuse box (refer to the owner's manual for the exact location).
Identify the fuse corresponding to the parking sensor system using the fuse diagram.
Remove the fuse using a fuse puller or pliers and check if it is blown.
Replace with a new fuse of the same amperage if necessary.

5. Test the System

Reconnect the battery.
Start the vehicle and test the parking sensors by placing an obstacle near the sensors.
Verify that the sensors detect the obstacle and that the warning sounds function as expected.
