Volvo models this fault code applies to
Applies to the following models:
9 modelsS60 (2011–), S80 (2007–), V40 (2013–), V40 Cross Country (2013–), V60 (2011–), V60 Cross Country (2015–), V70 (2008–), XC60 (2009–), XC70 (2008–)
What does this fault code mean?
The climate control module (CCM) receives outside temperature information from the engine control module (ECM) over the CAN network and checks the quality of that information. The fault code is set when the engine control module reports a lower quality than the climate control module accepts. The check is made with the engine running, and the fault lies in the sending module.
Possible causes
- Fault-trace the engine control module (ECM), since the fault lies there
What you can do
- 1No fault-tracing procedure exists for this code itself. Follow the fault codes in the engine control module first
- 2If you have a diagnostic tool, read the fault codes in the engine control module and follow them
- 3Clear this code only after the cause has been fixed and the code for the cause has been cleared
Symptoms you may notice1
- Temperature control or air conditioning does not work
General guidance for car owners. Diagnosis on the car can point to a different cause.
