Can anyone help as I am lost with my climate control module

[simonsen]

So I bought my xc60 ( 2010) around 5 months ago and we love it. Unfortunately we just realised that defroster / and driver side temperature damper are not working. Obviously I thought that motors are buggered so I ordered two online gutted dash board changed them and still nothing. I am getting some code stating that system has internal fault and incorrect components are installed. CCM-10874A. I tried dampers calibration - nothing, ccm calibration - no luck. I should mention that my driver heating seat is not working and on one forum someone mentioned that changing heating element cured the problem.
Help me please am I missing something?

I haven't checked any diagrams, but are you sure it's not just a fuse ?

[simonsen]

That was first thing I checked

Sorry - some folks aren't that technical !!

Since you've only had it 5 months, and if you can say that they probably never worked, you'd be within your rights to go back to the garage you bought it from (hopefully?) and ask them to repair it I believe, but you'd have to move quick, and in a covid secure manner.

Unfortunately car was purchased privately, it looks like someone was trying to sort it out before me as few plastic bits were broken.
I think it will be a matter of coding programming new/ used motors in vida but that's just my assumption.

As a final idea then, check out the vdash program - you have to buy a dice unit, but the chinese versions seem to work ok, and you pay for software configuration modifications - but it can work out a lot cheaper than going to a dealer, and once you're up and running with it, you can do quite a lot more. If you have a dice unit already, you could use it for diagnostics to some extent - although a downloaded copy of vida would also allow you to see button presses and the like. Good luck !!

Well it looks like ccm is at fault - problem i have now I can't find matching ccm part number online. There is a newer one which has all the buttons I need but part number doesn't match, also I found few with matching part number but that have less buttons missing parking sensors etc.

[JeffCooper63]

The buttons transfer really easily - if it's cheap enough, definitely get that same part no version and give it a try - even without the "option" buttons, you should still be able to test the vast majority of functions - especially the broken ones !!

I don't think the buttons are intelligent - I suspect each button switch has a code that's sent to the CEM, and then interpreted into the option that the car knows about, or gets rejected if it's not been programmed - your "buttons" are simply caps that clip over the switch. Or at least they are on my 2015 model, I guess I could be wrong for the earlier models sorry.

See if you can take to an auto electrician, they may be able to check connections/etc as it may be a wire to the module that needs fixing rather than the entire module?

I had similar with a rear door module, no power/etc but an auto electrician traced the issue that there was no cambus signal, this was traced and fixed and works great (touch Wood!).

I know this probably doesnt help much, but may give you a clue to the issue, and an intermittent issue could be a wire that is nearly broken and either touching every so often or a bad earth.

Not sure if this will help, but it will surely won't hurt to watch
