ON BOARD DIAGNOSTICS II (OBD II)

General

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 (DTC's) and system parameters. OBD II contains only emission related diagnostic trouble codes (DTC's) and parameters and cannot provide the comprehensive range of information available from the Volvo On-board diagnostics system.

Note! An SAE/ISO diagnostic trouble code (DTC) can correspond to several DII diagnostic trouble codes (DTCs). All of these must therefore by rectified in order for the corresponding SAE/ISO diagnostic trouble code (DTC) to disappear.

Several SAE/ISO diagnostic trouble codes (DTCs) may also refer to the same DII diagnostic trouble code (DTC).

There are DII diagnostic trouble codes (DTCs) for non emissions-related faults that do not correspond to any SAE/ISO diagnostic trouble code (DTC).
