Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and ensure it is secure.
Wear safety gloves and glasses.

2. Clean Camera and Sensor

Step 1: Locate the front-facing camera and radar sensor, typically mounted near the rearview mirror or in the front grille.
Step 2: Use a soft, clean cloth and automotive glass cleaner to gently wipe the camera and sensor surfaces.
Step 3: Inspect for any physical damage; if damaged, the camera/sensor may need to be replaced.

3. Check and Adjust Alignment

Step 1: Using a professional alignment machine, check the vehicle's wheel alignment.
Step 2: If misaligned, adjust the alignment according to manufacturer specifications (usually around ±0.1 degrees).
Step 3: Ensure all tires are inflated to the specified pressure (usually around 32-35 PSI depending on load).

4. Inspect Wiring and Connections

Step 1: Remove any paneling necessary to access the wiring harness for the camera and radar sensor.
Step 2: Inspect all connectors for corrosion, looseness, or damage; reconnect or replace as needed.
Step 3: Use a multimeter to check for continuity in the wiring.

5. System Reset

Step 1: Disconnect the battery negative terminal and wait for 10 minutes to reset the system.
Step 2: Reconnect the battery terminal and check if the Lane Keeping Assist function is restored.
