Diagnostic Trouble Codes
(DTC)
Interpret DTCs
In the remaining part of the manual you’ll find all DTCs from all control units in a Volvo car.
However, you will not find all definition variants to each DTC. The manual only presents the
all-embracing headline definition (marked red below). This is because of the limited space.
A complete list with all definitions for all DTCs is available on the home page.
