Diagnostic Functions: Notes

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2013 Volvo C70, 2012 Volvo C70, 2011 Volvo C70, 2010 Volvo C70, and 2009 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.

The control modules have a built-in diagnostic system, Volvo Diagnostics, which continuously monitors internal functions as well as input and output signals. The central locking system is a distributed system which stores diagnostic trouble codes (DTCs) in different control modules depending on where the fault occurred.
