Current limiting

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.

The central electronic module (CEM) checks and sometimes limits the current from the battery and generator.

The central electronic module (CEM) communicates with the alternator control module (ACM) via serial communication.

If there is a fault with current limitation, the general warning lamp will light in the driver information module (DIM) and a text message will be displayed.
