Climate Control Module Damper Motor Fault Topic is solved

Post by **Botbasher** » 03 May 2017, 21:57

OK... I'm now on to the next adventure with my T5.... The DTC code, CCM-000c!!!

VIDA has quite a bit of info on this, but I've run out of easy options!! Let me explain....

The error is that the right side damper motor has failed to move properly.... So I started simple. Swap the motor into a different position... OK, that works.

Check the wires. Yep, they all check back to the CCM, so no joy there!!

So that kinda leaves me with the thought that the CCM has a dead line. Is there anything that would stop the CCM from controlling a single motor? All the others work in the calibration except that one. Could my remaining PHM DTC cause a single channel failure in the CCM??

OK, barring the PHM causing this, I have a bad CCM. Are these things coded to the car or is a JY swap possible?

Anyone have a 03 CCM that I could test it with?

Cheers!!

Here's a deep one for your May 4th contemplation....

The 02 XC that I raped for the interior had a nearly identical CCM. The biggest difference was that the "fan" on the back plugged in externally rather than having the built in header like mine. Mine is a "03", but the data plate says late 02 build date, so at some point they changed the configuration.

Question is... Will they function the same even if slightly different? I would think so, but you never know.

Sadly I parted the XC one (before I knew I needed it) for the knobs and other internal parts, so getting it isn't an option. I'm currently on the look out for an ECC with heated seats and IAQS if anyone has one that I could even borrow for a bit to confirm the fault!

Cheers!

This is the ECC I'm looking for if any one has one I could even test with. I'll cover shipping!!!

Think many have this issue. Mine doesn't blow hot enough and not strong enough, and seems it's because a flap door doesn't fully open. I'd rather look into a re-calibration in the first place.

Been there... done that... Got a t-shirt to prove it!!!

I found that under the Fault Finding Tree. The damper motor literally doesn't move at all when in it's normal plug. Move it to any of the others and it moves easily. Swapped in a couple of JY motors.. no joy.

Since it's on a parallel powered cord, and all the other dampers work fine, I traced out the blue line all the way back to the pin on the back of the CCM. It checks good.

That leaves me in the CCM for the cause of the fault and since I haven't been able to find a board level schematic for component fault finding... it's swap & pray!

I did use VIDA to confirm that the system sees the temp knob... it does, so it should be trying to move it.. it just can't. The only thing I haven't been able to determine is if the PHM error could/is influencing the CCM. CAN-Bus and all... it's possible, but to only have a single motor not respond (since they are on a parallel comm line) is highly unlikely.

Thanks for the thought though... I would loved for it to have been that simple!

OK... I found one that I can test out with. It's the exact same CCM (with the header fan). Be here in a few days!

Hopefully that cures the CCM-000C error!!!

I'll keep you posted!

Keep it updated, this is getting interesting. Maybe a CEM issue?

Sorry to disappoint Oragex.. completely a CCM issue... But I have some definitive answers about it and the CCM!

I happen to be walking in the yard this morning and low and behold, there was a XC90 they just moved in!! Could it have what I needed??

I peeked inside and the CCM was gone! DAMN! So I look around the rest of the interior. Appears someone's been going through it. Headlights gone... Taillights gone... But wait... What's that under the seat?? Holy Hidden Jewel Batman!! The CCM was stuck under the front seat!

Pulled it out and Holy Schnikes... It has DSTC and a header fan!!! Someone destroyed the tabs pulling it out, so I proceed to pull the board out of it and find a safe place in my huge tool bag!

Got it home and pulled the bad CCM. Swapped the board. Even though this one was a 2003, this CCM has incredible conformal coating on everything. Like it was replaced recently.

So all back together and installed. Fire up the car and hazaaaaa!! Passenger damper is operational! Fire up VIDA and run a calibration. All good! I now have passenger AC!

So the take away from this...

You can have a single line failure for a damper.

The other DTCs on the same line don't seem to effect the CCM. Mine is a missing PHM module!

And the big one!! You can swap CCMs between cars without any programming. There were no additional DTCs regarding the CCM after I cleared the CCM-000C errors.

The one thing I did come to in all the reading is that to successfully swap a CCM, you need to stay close in years (don't try putting a 07 into a 02, stay below the change) and to have a donor that has the same equipment (my donor had DSTC and security, I have DSTC).

So, I'll have a spare CCM shortly as I eBay'd a replacement that I don't require anymore. Maybe it looks better than mine... Who knows?

So hopefully this will lead someone having similar issues into a quick fix!

Cheers,

Whereabouts in NC are you? I know of several P2's in yards where you could score a CCM cheap.
Edit: My bad, didn't read through everything. Congrats on the repair

Winston... And you?

I'd never pass on parusing a bone yard find especially if there's a nice drive involved!! That's the thing with that particular repair... Cheap is good, but it has to match on many levels and a T5 had a lot of frills that base V70 didn't as I'm finding!

Currently looking for a XC grill for this thing. Realized this weekend why my buddies R looked so much better... Guess I got to the point where the outside worries me more than the inside now!! That's a good place to be!!

Cheers!!
