Replacing the control module

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.

The diagnostic trouble code (DTC) indicates an internal fault in the central electronic module (CEM) which means that the control module needs to be replaced.

Read off the customer parameters from the control module before it is replaced. Click on the VCT2000 symbol. Make a note of the values.
