WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.
Stored diagnostic trouble codes (DTCs) can be read off and erased using this function.
After the diagnostic trouble code (DTC) is stored it can also be read off if the fault is still present (permanent fault), or if the fault has disappeared for any reason (intermittent fault).
Diagnostic trouble codes (DTCs) can only be erased when all diagnostic trouble codes (DTCs) have been read at least once.
