    What OBD tool do you use? Do you have power on the OBDII port's pin 16? Posting the codes you have would definitely help. For example, if you were to post you had P0A0D, we could advise you to check whether the service plug grip has been installed properly. Most people fail to complete step three, for some reason.

    When you press the start button do you hear the 2 clicks of the relay by the traction battery? For sure check the safety tab as Dolj suggested.
