OBD II is a diagnostics system designed to meet statutory requirements. Fault-tracing instruments can be plugged in to the OBD II socket in order to read diagnostic trouble codes (DTCs) and system parameters. OBD II contains only emission related diagnostic trouble codes (DTCs) and parameters and cannot provide the comprehensive range of information available from the Volvo On-board diagnostics system.
