Step-by-Step Guide: Using iScanner on Your Mercedes-Benz Truck

Alright, let’s dive into how you actually use iScanner on your Mercedes-Benz truck. Don't worry, it’s not rocket science. Here’s a step-by-step guide to get you up and running.

• Step 1: Preparation: First things first, make sure you have the iScanner tool, any necessary adapters, and your Mercedes-Benz truck ready. Ensure your truck is parked on a level surface and that the ignition is turned off, but in the "on" position (or the engine running if you're checking live data). If your iScanner requires a power source, make sure it’s properly connected.
• Step 2: Locate the OBD2 Port: Most Mercedes-Benz trucks have an OBD2 port located inside the cabin. Typically, it’s located under the dashboard, near the steering wheel, but on some models, it might be in the center console or under the glove compartment.
