Diagnostic Trouble Codes (DTCs)

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2009 Volvo S60, 2008 Volvo S60, 2007 Volvo S60, 2006 Volvo S60, and 2005 Volvo S60. However, it is still accessible from the selected car via links, so may be relevant.

A diagnostic trouble code (DTC) is stored if the control module detects a fault. The control module can store up to 10 diagnostic trouble codes (DTCs).

Should a fault disappear for any reason after being stored in the control module as a diagnostic trouble code (DTC), the information remains stored in the control module. If a fault is no longer permanent, the diagnostic trouble code (DTC) remains as intermittent.
