Diagnostic port location (OBD)
Illustrative — for orientation only.
Under the lower edge of the dashboard on the driver's side, just left of and below the steering column, above the driver's left knee: the spot where most cars have the bonnet (hood) release (on the ATS the release sits lower and further in, so do not confuse the two). The 16-pin connector is recessed and faces down, so kneel in the door opening and look up under the dash edge. Same position on sedan, coupe and ATS-V, all trims 2013-2019; US-market ATS are left-hand drive only.
