Diagnostic trouble codes (DTCs)

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Volvo V70, 2006 Volvo V70, 2005 Volvo V70, 2004 Volvo V70, and 2003 Volvo V70. 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 passenger door module can store up to 10 diagnostic trouble codes (DTCs).

Should a fault disappear for any reason after being permanently stored in the control module as a diagnostic trouble code (DTC), the information remains stored in the control module.
