Volvo models this fault code applies to
Applies to the following models:
7 modelsS60 (2011–), S80 (2007–), V60 (2011–), V60 Cross Country (2015–), V70 (2008–), XC60 (2009–), XC70 (2008–)
What does this fault code mean?
The climate control module (CCM) compares its configuration ID with the one that the central electronic module (CEM) sends on the CAN network. If the IDs do not match, the fault code is set. The module then answers only diagnostic commands, and normal CAN communication does not work. The fault may come from a used module with the wrong software.
Possible causes
- Faulty configuration ID, because the module is not meant for this car (for example a used module with other software or hardware)
- Intermittent open circuit on one or both CAN wires in part of the network
What you can do
- 1Has the climate control module recently been replaced? If so, check that it is meant for this particular car
- 2If you have a diagnostic tool, read the code after a restart and note whether it returns
- 3Check that the CAN wire connectors are secure and clean
- 4Have a workshop reload the software in the climate control module
- 5Leave the CEM in place for a CAN fault unless troubleshooting shows it is faulty
Symptoms you may notice1
- Climate control does not work at all
What the fault can affect2
- The module stops sending messages on the CAN network
- The functions of the control module stop working
General guidance for car owners. Diagnosis on the car can point to a different cause.
