Volvo On-Board Diagnostic (OBD) port, also known as OBD-II or OBD 2, is located under the dashboard on the driver's side.
The Volvo diagnostic port is used to read fault codes, clear codes, activate the sensor, and program the various modules.
Volvo OBD-II Port Location
Use the OBD-II port to diagnose all warning lights.
Check engine lights can be diagnosed with a generic OBD-II scanner, but systems such as ABS, Airbag, SRS, and Transmission require a Volvo scanner.
Did you know that all 1996 and newer Volvo vehicles sold in the US have an OBD-II port under the dashboard?
