Diagnostic Trouble Codes (DTCS)

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2014 Volvo XC90, 2013 Volvo XC90, 2012 Volvo XC90, 2011 Volvo XC90, and 2010 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.

If the control module detects a fault, a diagnostic trouble code (DTC) is set. Any fault detected during the last run cycle is defined as permanent. Other faults are defined as intermittent. A run cycle comprises ignition on, the car speed exceeding 10 km/h (20 km/h in XC90 with B8444S engine) and ignition off.
