Signal Specification

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.

General 

All the values given below are between the terminals stated in column 1 and terminal #D12 in column 2 (power ground). This applies unless otherwise indicated in the last column.

NOTE:

It is important to connect the breakout box and check the ground connections before starting to measure.
