About Volvo Trouble Codes (DTC)
OBD II is a diagnostics system designed to meet statutory requirements. A standardized instrument for fault-tracing can be plugged in to the data link connECM-tor (DLC) (OBD II socket) to read diagnostic trouble codes (DTCs) and system parameters.
OBD II contains only emissions related diagnostic trouble codes (DTCs) and parameters. It cannot provide the comprehensive range of information available from the Volvo On-board diagnostics system. Volvo has its own diagnostic trouble code (DTC) designations that adhere to the in-house Volvo On-board Diagnostics protocol (called DII from model year 1999).
Table explanations
The table below is a conversion table between standardised diagnostic trouble codes (DTCs) (SAE/ISO) and the equivalent Volvo diagnostic trouble codes (DTCs) (DII). SAE/ISO diagnostic trouble code (DTC): Standardized diagnostic trouble code (DTC) according to SAE J2012/ISO 15031-6. The diagnostic trouble code (DTC) can be read off on vehicles with standardised on-board diagnostic systems for emissions related faults, certified in accordance with OBD II.
