Signal Specification
WARNING: This page does not describe the selected car, but rather 6 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.
Connector C, terminals #C1-#C2
All values given below are between the terminals stated in column 1 (terminal in the breakout box) and terminal #C2 (ground). This applies unless otherwise indicated in brackets.
NOTE:
It is important to connect the breakout box and check ground terminals before reading off.
