Rear 12 V socket
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.
There is a 12V socket on the right-hand side of the cargo compartment. This socket can be used to power a number of accessories.
The socket is directly connected to the 30-supply via a fuse and a directly connected shunt on the rear electronic module (REM).
The rear electronic module (REM) measures the current through the shunt periodically and calculates an average value. This is compared with a limit value to determine if any power consuming component is connected.
This information is transmitted via the Control area network (CAN) to the driver information module (DIM) which displays a text message when a power consuming component is connected (applies only to factory installed 12V sockets).
