Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, cleaning supplies (cloth and water).
Park the vehicle on a flat surface and turn off the ignition. Disconnect the battery to ensure safety while working on electrical components.

2. Clean Sensors

Sub-steps:
- Locate the front sensors mounted in the bumper.
- Use a soft cloth and water to gently clean each sensor lens to remove dirt or debris blocking the sensor.
- Dry the sensors thoroughly to prevent water from affecting functionality.

3. Inspect and Repair Wiring

Sub-steps:
- Reconnect the battery and use a multimeter to check for voltage at the sensor connectors.
- If no voltage is present, trace back to the wiring harness for any breaks or damage.
- Repair any damaged wires by splicing in new wire segments and using heat-shrink tubing for insulation.

4. Reconnect and Test

Sub-steps:
- Reconnect the electrical connectors to each sensor ensuring they click into place securely.
- Clear any fault codes using the OBD-II scanner.
- Perform a system check to ensure sensors are recognized.

5. Final Testing

Sub-steps:
- Take the vehicle for a short drive to allow the sensors to recalibrate.
- Test the functionality of the front sensors by engaging the parking assist feature.
