CCM-dd01 fault
 

Hi

2011 XC90 executive

Climate control fault CCM-DD01 I cannot clear the fault, cannot recalibrate and I have replaced the climate control module, none of motors move and heat is on one side and not the other

Anyone have any ideas as to what I can do next please

Long shot, try disconnecting the AQS, and see if things return to normal (under the scuttle on the ns.) It can have lots of issues on the network if faulty, esp one side cold one side warm.

Hope it helps. :regular_smile:

Oh, you will need a puller to remove the wiper arms.

Try unplugging the heated seat modules (assuming you have them) - if they fail they can cause problems on the Lin Bus. You'll find them under the seats.

You may need to re-calibrate the CCM as well - you'll need VIDA to do this.
