Before connecting the Data Cable to the vehicle’s OBD-II Data Link Connector, switch ignition to Key On Engine OFF.
Plugging in the cable
Now connect the Lighted Data Cable to the OBD-II connector. The ETHOS Edge will automatically power up if not turned on already. Wait for the beep! Select Scanner. Depending on the vehicle, Instant ID may occur automatically and only ask you to confirm the vehicle, or additional screen prompts may be displayed to enter vehicle information.
