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.

Launch software and click "connect" button. Your OBDLink EX scan tool is now ready to use.
