Step 3: Scan for Diagnostic Trouble Codes (DTCs)

Step 4: Inspect Wiring and Connections

Visual Inspection:

Step 5: Reset the System

Clear Codes:

Test the System:
- Take the vehicle for a test drive to see if the LKA system functions correctly after the reset.

Step 6: Consult Professional Help
