Cadillac OBD2 Port Location
The diagnostic port, also known as OBD-II or OBD2 port, on Cadillac vehicles is located under the dashboard on the driver’s side. Look under the dashboard right above the brake pedal.
For short, the OBD-II diagnostic port, or OBD port for short, can diagnose vehicle problems, reset codes, stream live sensor data, and reset warning messages. You will need a Cadillac Diagnostic Scanner to access advanced options since a generic OBD-II scanner can only read and clear check engine codes.
Most Cadillac, including ATS, Escalade, CTS, SRX, STS, XTS, CT6, and XT5, have the On-board Diagnostic (OBD) port under the dashboard driver’s side.
The diagnosis port will allow you to read and clear fault codes from the Engine Control Unit. If you have an All System Scanner for Cadillac, you can read and clear codes from any module, including transmission, airbag SRS, transmission, climate control, ABS, traction control, and more.
A basic OBD-II scanner will only access trouble codes related to the engine. It will not show any other fault codes, even if warning lights are on.
