I had a kid clean my car and he killed something in the CCM trying to remove dust from the vent on the front. Now the CCM is almost completely dead. I say almost because you can just barely see the light in the recirc switch glowing at night. I got a used one and it was not the exact part. It looked identical, but it was not as wide so there was about 1/4 inch gap all around. This unit did work, a little. It would work the temp and fan, but nothing else. It also had the added feature of never turning off, so I had to pull the fuse to get it off.

I got another used module that was working in the car it was removed from, and is identical to my part. It does not work at all.

The dealer said it is a VIN specific part and will only work in the car it was installed in. He claims I HAVE to use a new part and load the new software. $1,400!

Is this true??? If so, why are there so many used modules for sale on eBay and used parts forums? If not, can anyone tell me how to get this module to work in my car???

Car is 2001 S60 -- Dual automatic climate control with Defog, rear window defrost, dual heated seats, auto-recirc module.

Thanks in advance for any help!!!

 

Unless some one figured out how to do it you cannot put a used one in.

People are selling them like mad because they do not know any better.

 

Thanks, but I have found that this is not true. I got a part from a 2002 V70. It was the exact part number as mine. It works perfectly. $25.

So, from what I have found from others who have done the same thing, the part numbers must match and it has to come from the exact year and model, or one very close to it for there to be a chance for it to work.

Just my own .02, but for a part this poorly made and with the reliability I've read concerning it, it's absolute robbery to charge $1,400 to replace it. Add to that the extreme lack of knowledge from so called Volvo specialists at the dealership, and I have one very strong argument to make this my first and last Volvo.

 

Good luck I hope all works out well for you. I have seen more not work than work when trying that.

I agree it is way to much for the module and programming.

 

MAX AC only works on higher temps

As for the climate, yes it can be the module only way to find out is to swap with a other car and see how that turns out.

Welcome here

 

From your first post to your 2nd post, what did you have to do to get the '02 CCM to work? Also did you just "plug 'n' play" or did you need to take it to the dealer for a software upload/upgrade?

Also, was the '02 V70 module close enough? I have an '01 S60 and found an '01 S60 CCM. Do you think that is close enough or will I need to ask the supplier for a part number to match? It has the same or similar features.

Thanks

 

I am guessing you are refering to the small wire with a bead on it behind the slots over the passenger side temp control ****, when mine got broken I bought a used one from E-Bay and replaced the thermister in mine with the one from E-Bay, the module that came with the car stayed with the car. I did state a requirement that "the wire behind the vent over the passenger temp control be intact". Basic soldering skills are required.

 

When you replace a CCM head, it has no idea where the damper motors are at or where their limits are. You must reload the software and calibrate the head for it to work properly. As for used units, I have many, MANY customers come to my shop with inop used heads that dont work. Usually end up buying a new one and being out the money for the used one. We have a moto at our shop. "Get it fixed somewhere else, you'll be back to get it FIXED".

 

V-60, I made sure it was the exact same part number and from an almost identical car. No dealer or programming was involved.

 

Precisely why this will be my first and last Volvo. IMHO, risking $25 to save $1,400 is acceptable risk. However, you illustrate better than I the superior, condescending attitude that I experienced with Volvo dealer techs. I might also suggest that the used units your customers brought in were probably inoperable when they bought them due to the high failure rate of these units due to their poor quality. If they cant be made more reliable, then they should be repaired more economically.

My motto for this car is, "If I cant get it fixed somewhere else, then trade it."

 

Volvo's are complex. I have worked for a few dealers and Volvo's are definitely the most complex to learn. But once you do, its fun. The CCM does not have a high fail rate, but the customer cutting corners is. I often recommend brakes and the customer comes back a week later because they put cheap parts on and they have squeaks, vibration, and other terrible problems. Just the other day, a car needed spark plugs because they neglect their service guide, customer declined and installed some cheap autolite plugs. Guess what came back today for misfire and check engine light? Now he has to pay twice. Used modules happens alot and usually causes more problems than needed. They are inop because their are soo many part #'s that seem to change daily as well as the need for a software download/calibration to most modules once replaced. I agree the software downloads are a bit too much sometimes, but it is what Volvo does and gets away with.

 

Ha! Same issue, same result. Bought a new-to-you 2001 S60 & was cleaning that little fan on the AC module. AC, etc. kaput & check airbag URGENT light on.

So, off to the repair shop. Spent >>3<< hours having Volvo trouble shoot something they had essentially told me over the phone was the problem. Only question was whether it was connection or the module needing to be replaced. How long 'should' it take to run diagnostics on a 'known' (or I should say widely recognized/reported) problem? They only charged me for an hour of labor -- but wasted an additional 2 of mine.

Here's my question to the forum: Might a software reset/reload cure this or should I bit the bullet and pay the $1350 to replace the CCM? Diagnostic summary said "found DTC CEM at 1A55" (assuming that is a memory location) "No communications with other modules on low speen network. checked connection at CCM OK. Checked power at CCM OK. Checked ground OK. Needs new CCM". When I asked the tech he said he cannot just reset the software (but others in this forum have had success ...though I suspect they may have had lesser comms problems on that low speed network)

 

Wow, hmm. Lots of bad dealers around, it sounds like!

You can swap CCM, there's no software to load, but you DO have to reset the ECU's faults. It doesn't take very long, and anyone who has done ANY work on any Volvo using VIDA/VIDAS/DICE should be able to do this extremely quickly.

The CCM compatibilities are:

- '01-03 V70
- '04 V70
- '05+ V70 (So long as it's still a P2 chassis)

Compatibility is dependent upon having a) The right switches (you should be able to swap your old ones on) and b) The right options. IAQS CCM will work with an IAQS CCM-equipped car and the other way around. Temperature measurements need to be the same, too (C or F.)

OJO: You probably don't need a new CCM OR a software download, you just need to get them to run the delivery validation tests again, and it will likely clear up, unless there's a worse underlying problem.

The reason the newer ones won't work with the older ones is the CEM and security module is integrated heavily into the '01 to '04 models, and you'll not be able to unlock/lock your doors. That, and the fact that the later models rely on having a plastic frame into which the pieces slide, which is then slid into the normal dash opening, whereas the earlier ones use a slightly longer climate control module that is designed to push against the head unit above it to press into place.

The later model parts will physically fit as long as you have the frame, but getting to work with the CAN/electronics is something I've not really got a good answer for.

This is all from just my personal experience with working on a huge amount of Volvos and doing a lot of CCM work. A dealer SHOULD have mechanics that also know these things, plus more, but I rarely encounter that. I don't trust dealers at all for a number of reasons similar to this.

Beyond all that, to address people's concerns with this being 'overly complex and absurd' have clearly not worked on many modern cars that have automatic climate control! Aside from cable controls, electronic climate control is often quite like this. It's no different in any BMW, Jaguar, Porsche, Volvo, newer Subaru, Toyota, Hyundai and so on and so forth.

So, if you want to avoid this problem entirely, and don't want to deal with ECC/don't get any benefit from it, I recommend getting a car with manual climate control. =)

But this principle can be applied to anything; You don't want to have an ETM (electronic throttle), automatic transmission, climate control, power windows, power seats, central locking... All of these have ECU-registered components that need to be validated are within specification and have had full diagnostics done to make sure they are operating correctly. These validations exist to ensure the car operates consistently and safely, and allows for fewer potential mechanical failures (basically trading the possibility of mechanical failure for electrical failure.)

Ahem. Sorry, I went off a bit tangential, but at the top of this post should be some useful information, at least!

If only that were so! The ECM got fried when we tried to clean that dirty little fan in a used car we bought, then seeing that something 'blew' we checked fuses, then we pulled it out to trouble shoot it without disconnecting the battery. Our fault. That said, to me the ECM seems insanely sensitive, not complex. Anyway, the ECM was able to be repaired & reinstalled, but <shocked face, > the dealer never offered this option. So I saved myself $1000 finding someone with the bench & skills to fix it.

To follow the complexity thread, based on limited experience & moderate research, I am lead to believe Volvos are not overly complex (or advanced) compared to their peer-competitors but that (one hypothesis ) they're poorly designed. (changing cabin air filter; adding fog lights are 2 examples) I happen to like my electronics...but I think the current state is either immature (advanced, yes, but still ...inelegant? unnecessarily hard/expensive to repair?) or self-serving. Neither of those will win me over to ever buy another used &/or a new $60k Volvo.
