Signal specification

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Volvo V70, 2006 Volvo V70, 2005 Volvo V70, 2004 Volvo V70, and 2003 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.

General 

Values specified below are between the relevant terminal and terminal #9 (power ground).

U= DC voltage in volts (V)  
Ubat = Battery voltage (V)  
Ulow = Voltage approximately 0 V
