Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean Safety Sensors

Locate the safety system sensors (e.g., front radar, cameras).
Use a soft cloth and appropriate cleaner to remove any dirt or debris from the sensors.
Ensure that no obstructions (e.g., stickers, dirt) are present around the sensor area.

3. Repair or Replace Faulty Components

If a specific sensor is identified as faulty, remove it by unscrewing any bolts and disconnecting the wiring harness.
- Tools required: Socket set, screwdriver set.
- Safety warning: Ensure the vehicle is turned off and battery disconnected.
Install the new or repaired sensor by reversing the removal process.
Torque bolts to manufacturer specifications (refer to service manual for exact torque values).

4. Reconnect Battery and Clear Codes

Reconnect the vehicle's battery.
Use the OBD-II scanner to clear any C-codes from the system.
Start the vehicle to verify that the system is functioning correctly.

5. Final Testing

Perform a thorough test of all safety features (adaptive cruise control, lane-keeping assist, etc.) to ensure they are operational.
If the C-code reappears, further diagnostic steps may be required.
