Windows PC Quick Start Guide
Step 1: Install software
Step 2: Connect EX to the PC
The LED will turn yellow when you connect EX to the PC’s USB port.
Red LED? Drivers were not installed properly.
Note: If the drivers for EX do not install automatically, click on the link below to download the driver.
Step 3: Locate the OBD port and plug EX in
The diagnostic connector is always located in or near the interior dashboard of your vehicle. The diagnostic connector will usually be exposed, but sometimes it’s hidden under a decorative plastic cover, or behind an ashtray or coin tray. The most common location is below the steering column, just below the driver’s dash area. Don’t use excessive force, but make sure it fits snugly.

Step 4: Turn ignition to Key On, Engine Off position
On some vehicles the ‘ON’ position is marked with the Roman numeral ‘II’. If there are no markings, turn the key clockwise and stop just short of starting the engine.
The LED will turn green.
Note: Vehicles with push button start: press the button without stepping on the brake pedal.
Yellow LED? Check OBD port, auxilary port, and the cigarette lighter for blown fuses.
Step 5: Launch software
Launch software and click “connect” button. Your OBDLink EX scan tool is now ready to use.
