1. Under the Dash: The most common location is under the dashboard, on the driver's side. Look for a black or gray connector near the steering column or center console.
2. Near the Fuse Box: It could be located near the fuse box, which is usually found under the hood or in the passenger footwell.
3. Check the Owner's Manual: Your Honda Civic's owner's manual will have a diagram showing the exact location of the DLC.
Once you've found the DLC:
* Ensure the ignition is on (II) but the engine is off.
* Connect your scan tool to the DLC. The connector on your scan tool should match the shape and size of the DLC.
Important Note: For older vehicles, the DLC might be located in a different spot, or there might be a different type of connector used. If you're unsure, it's always best to consult your owner's manual or a qualified mechanic.
