I am warning you in advance, that I am a newbie who knows the basic theory and enjoys watching a lot of youtube videos of Mike, Dave, AvE, Jerri Elsworth, Applied science and so on, however, I am not by far an electronics engineer. I have an automotive repair dilemma here which ultimately boils down to electronic fundamentals in repairing a water damaged device that processes CAN signals.

INTRO start skip this if you are not interested in the explanations I own a volvo s80 that has stood on the outside for some time and it has turned out, that it has the infamous sunroof drain problem which in turn has caused water damage to the Central Electronic Module of the car. If anybody is interested in more details, please ask, but I arrived to this conclusion after a few basic fixes of the failed window washer pump did not work And after taking out the module itself, you can see the substantial damage caused to it.

The repair at the dealer costs too much for me to consider this option - EUR for the module plus another approx. All of that being done to prevent these modules from being stolen and sold left and right.

I have googled quite a lot and it seems that these modules are easily repairable, and a few people have completed it, but with different main causes. As well as there are services that specialize in the repair of these devices. I have a donor device, but I am not sure of the internals as I haven't had the time to pry it open and see if they are similar internally.

A picture of the old and new devices from the blog for those who do not surf links: Due to the fact that my CEM module is badly damaged, I do not think that a lot of the components will be usable as the water has corroded a lot of pins which have come out, as well as surely corroded much more.

This leaves me with the option, that is being stipulated in the blog above: " read flash from dead CEM; re-program new replacement CEM, done. Thanks, Juris. Unless you are very well experienced, this isn't a solder job I'd recommend a beginner to attempt. Also, do you own the equipment to do the job? If it means buying a hot-air station, programmer, new chip etc. Can you post some pictures of your device so that we can assess the damage?

Thanks for your reply, McBryce, but it seems to me that repairing the device itself is too costly compared to the fact that they are easily copy-able, even though bound to the car. Some extent of the damage can be seen on the pictures in the bottom gallery - more the connectors then the board itself, but, ahh, well.

I have done a fair bit of reading in multiple languages on this, and apparently the water damage, as well as over-heating of the MCU is a very common problem. There is even a service of copying the data over to a refurbished device.Welcome Guest Log In Register.

Central Electronic Module Repair & Return for Volvo

Started with radio getting stuck on one station but now the instrument panel goes dead or the windows won't work or the message center comes up with all sorts of warnings. Car seems to run fine though. The service manager is a good guy and I trust his judgement. He wasn't sure if I got one from a wreck whether it would plug in and go. Anybody tried this?

Hope this helps those of you in the ECM swap process. This was earlier. Benefits for this feature are several:. To erase, follow these steps:. ECM is now "virgin" and can now be swapped with another vehicle or used later. Sometimes the car may start, even though the "erase" SW has been downloaded. This is no error, and it will still be possible to do a ECM reload in another car. It does read that way, but I'm currently seeking advice from someone more knowledgable about this.

I've talked with Lucky about this. He knows how to change the immobilizer code, so that it is blanked. I've got 2 spare ECU's for cars, and Lucky told me that he can use those to clone another car, or so the owner could have a spare ECU if s he wanted. Did you ever get any more information about this? I'm sorry I don't have any new information at this time. Start new topic. Recommended Posts.

Thanks God.So lets put it in writing with things we KNOW work, not what we heard or someone told us.

I will reflect my personal experiences and will happy to update the original post with known swaps. Breakdown will be by platform.

Central Electronic Module Repair & Return for Volvo

ABS - Yes, early years only. If it says BCM, it's programmed to the car. Also, early DSTC modules cannot be swapped. Buttons do not have to match IE; seat heat button can be swapped and function. SRS - Yes, but only on early S80's. Look for chassis break, late break modules can't be swapped. I know I've forgotten many and there are few more platforms to add.

Please post up what you've successfully swapped or corrections to anything. You missed ETM on P2 cars. Supposedly, these cannot be swapped on any of the cars '99 - '01, they are VIN matched. However, I had an ETM that was bad, but didn't fail the sweep test, so factory rep made a deal that he would replace mine, and if it fixed problem, I got a warranty ETM.

You know he wouldn't take it back unless he could reprogram the VIN number. Go figure, but that was on a C70, I think. I also think the ECM can be reprogrammed, but again only by the dealer. Xemodex probably hasn't tried, but I'll bet they could.

I'm about to send a junkyard UEM to Xemodex to let him see if he can reprogram the VIN in that, as well; he's never tried to do it before. ETM's can be swapped, I've done dozens of them. ECM can absolutely not be swapped, tried that too. Please only post confirmed swaps not speculation! I've also been able to access the used unit and reprogrammed it with my DiCE.

Interestedly, I was also able to clear the DTC for altered mileage.Transfer includes the software, VIN number, key codes, mileage as well as the original CEM configuration and settings. The CEM will not need any additional reloads or calibration. Plug and Play! Please note: If your CEM lost the key codes from its memory then the transfer will not be possible. In this case please opt for virgin Un-programmed CEM. We always verify the number of keys programmed prior to the transfer.
