Verifying Repairs: General
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.
After carrying out repairs it may be necessary to check that the fault really has been remedied. One way of doing this is to check that the engine control module (ECM) has carried out a self diagnostic for the function / component that has been repaired, and that the diagnostic trouble code (DTC) has not recurred.
Verifying repairs is only intended as an aid if uncertain whether the fault persists or not. If an obvious fault is detected during fault-tracing it is not necessary to verify the repair.
