Signal Specification
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2011 Volvo XC90, 2010 Volvo XC90, 2009 Volvo XC90, 2008 Volvo XC90, and 2007 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.
General
All values specified below are between the relevant terminal and terminal #8 (power ground).
NOTE:
It is important to check ground terminals before taking readings.
| U= | DC voltage in volts (V) | ||
