thank you so much for sharing it.

Thank you. I just snapped a picture of the relays/shunts with my phone to record their placement for reassembly. This video helped me get at my CEM ('02 v70 2.4t).

Thanks. This is very helpful. I've just had my CEM checked, a new processor installed and reprogrammed. All is well now. It helped considerably that I could remove the module myself and take it to a specialist. At £100 per hour labour it saved me a lot of money.

what astoundingly great service...to suggest I disconnect the siren in hopes o f relieving the no start problem!! Thank you for that. I wonder if the car will still run if I just disconnect the siren? I see the challenge of replacing the battery, and do not feel I need the siren, and happy to do without it is the start problem solved. Await you expert opinion and leave my gratitude..Thank You!! Bill

Awesome video! This is giving me a new hope to a problem I am having with my 2004 CX90 T6/AWD. The CX90 is running quite smooth just like when I first drove if off the lot back in NOV 2003. I have parked/garaged it for almost two years because of an “intermittent” problem that a VOLVO dealership could not fix, they could not even tell me what causes the problem. MY XC90 engine will just cut off without any secondary indications, but each time this occurs it will start right back up and run like nothing happened. The Volvo dealership stated they could not see any codes on their Engine/Computer Analyzer that would cause my XC90 to cut-off in that manner. They practically said we can’t fix it but will give you $$$ (a lowball offer) if you trade it in… I said, “no thank you”, and I just parked it. I would like to inspect my CEM as you have demonstrated on your video before I make another step/decision. 1. If I unplug the CEM to “visually inspect”, will I be able to operate/start the XC90 again upon re-plugging it back to the harness? 2. If there is evidence of corrosion on the CEM, do you have a local branch near Richmond, Virginia that can repair the CEM . I’d greatly appreciate any assistance you can provide. Thank you!

Great video, I'm about to remove a CEM from a 2004 S60R, it has a suspected CRM problem with the following conditions : clicking under drivers side dash followed by all gauges going back to zero then they come to life again, get a bit further down the road and gauges and digital readouts drop out followed by a big clunk in the transmission. By this stage the CEM appears to have shut down resulting in the power windows, AC control and blinkers not working, a quick pull over and turn the ignition completely off and on again will usually gain control of most systems again but it doesn't last long, this car has only 112,000 kilometres but I have another similar car with double the kilometres and it has no issues. I will remove the CEM and retrieve the part number and email this to you. Hope this helps others diagnose the CEM.

Thanks for this video

Excellent. Thanks for sharing! But did you do anything about sealing the leak where the water intruded originally?

Just in case anyone is trying this with a V70, you have to turn the little tab on the side foot compartment molding before you just rip it out like he did in the video or you will break something. It then pushing toward the rear and pops out. Also, the xemodex troubleshooting document that brought me here talks about running the car with various environments (e.g., with relay removed and voltmeter attached) designed to duplicate / diagnose problem. How is that supposed to work if I have to disconnect the battery?

Muito obrigado!! Me ajudou muito!!!! Parabéns!!!

do you think if I have the aircon on full blast it would help me make that 1000Km? or taking off the covers and blasting the aircon and/or a cigaret lighter fan (bit of an out there idea I know).

I have a 2006 s60 2.5t with a CEM issue. Do you have any recommendations online that will fix them? I have none very close locally and the mechanic I have taken to has told me a repair like this still has a chance of not lasting even after repair. So I’m just wondering if it’s common to run into the issues more than once even after repair or should I send it to a better repair man. Also I was told if this repair doesn’t last I’d have to get a new part and completely recode it to my specific vehicle. And once again I don’t have a lot of options locally than help. The car is gonna cost me a fortune either way but I just need it back moving either to drive or sell.

Thank you.

I’m about to do this to my S40. I’ve been getting many intermittent alarms (all of them) and door electronics issues. (windows, locks, etc.) I hope this helps my problem.

Great video, thanks! I have a 2001 V70 T-5 and I didn't get to change the timing belt for the 3rd time quick enough and it broke. Engine is obviously now dead. I am looking at a 2003 S60 that supposedly needs a new CEM. Wondering if the 2001 CEM is compatible with and can be used in the 2003? Thanks. John

when it turned off I heard a clicking sound from the area where the CEM is located. Does this mean it could be something else or it is still the overheat issue?

Hi, was just looking at your video and it seems you really know what your doing here. I have a 2002 Volvo S80 2.9 that drives normally but the gear position indicators on the dash are just "dashes", also has a "transmission service required" light on the dash. Once again I want to say that the car presently starts up drives and shifts normally, but I am wondering what could be causing these indications. Any help you could provide would be greatly appreciated. Thanks.

How to fix Communication with the lamp switch module (LSM). Signal missing?

This could be the answer?? My 2000 S80 has different engine (not sure which one), but intermittently hard to or refuses to start,,turns over, does not sound like fuel pump engaged. sun roof won't open, battery drains, sometimes if I jump to start it then stalls..based on your expert experience, do you suggest I send the CEN to you to solve? Very gratefull for what you provided for us all, now await your verdict..Thanks, Bill

Thanks a lot

Hey man useful video! I have a rather interesting project. I have a 2020 S60 heated/ cooled seat with all the elctrical components. I believe the module found under the seat is what controls the axis movements on the seat. However is there a possibility that I can (lets say a raspberry pi) contol the heating and cooling functions of the seat? Note the seat is not in a car and will not be, however I would like to be able to to control all functions of the seat. Any chance we could communicate? Any insights I would be absolutely thankful for!

hi, is this a CEM Type-1 type2 or Type3? If it's for a 2002 Volvo v70xc , does it use type 1 type2 or Type3? I need to know as I am told that to program new key I need to know what type it is. Thanks if you can reply but quickly.

Hello, Thanks a lot for the great illustration and repairs video. I have a 2002 Volvo S80 2.9 litres car of which I lost the start key for some years now. I decided to keep it in the garage till i get a good and competent programmer to reprogram a new key for it. Unfortunately, the one who worked on it took away the original CEM and the uncoded key for the programming, then came and fixed it back, but the Dashboard signals and lights were all gone with nothing working. Not even the window glasses. The only signal on the Dashboard was the "Check Engine". The car couldn't start neither. I tried another programmer who later also destroyed the traces on the motherboard for the main CHIP when he tried to read the code. I got mad and took the key and CEM back. I'm totally confused and wish you could advise and help me out. Is there any way I could send some pictures of the car and the destroyed traces in the CEM? So that you see clearly what I mean. Thanks again.

I have a 2004 XC 70 with a po 600 code. Engine light on and message box shows transmission service required, but car seems to drive fine. Any suggestions on what I should do?

Thanks for the informative video! I have a some questions. 1, what was wrong with the car in this video. (What electrical issues was it having before repair that made you pull Central Electric Module?) 2, the water intrusion, where did it come from? And did you address that issue? (I just rear the other comments and saw that you suspected it was from sunroof drain. Has thet car been back? 3, what kind of warranty do you give on this repair? Thank you. FL Bill

Hi XeMOFeX i would like to ask about my xc70 D5 manual 2007. Because i check my dtcs diagnos i saw my CEM,BCM and DEM are need to be set. Do you think all of this need to repair or one of those is broken and causing some modules to error.? Thanks

If I do this and maybe stop for 2 hours after every 300Km, could it fail so bad at some stage that the car will stop working?

Hello XeMODeX, Great video ! Question, (I'm French, so sorry for the bad English), my dashboard won't come on when I start the car but the engine is running and I can drive. I have a xc90 - 2004 - diesel. Volvo says that I have to replace the DIM and the CEM. Can I buy a reprogrammed one on the net or do you sell these things ? Also, the car is less powerful since the problem appeared. Best regards, Alex

Вольво с60р 2005г Такой вопрос, гена выдает на холостом 13.4 под нагрузкой 11.8 Гену менял на другую тоже самое, кидаем на стенд у генераторщиков 14.3-14.1 гена обслужен. на тачку 13.4-11.8 Акб в норме и меняли на другой.

hi I'm in the UK do us reaper the e.c.m on Volvo s60 d5 2006

Hey I love your vid.. I have xc90 from 2003 and i have "breakfail. Stop now" and code is CEM 1A5F. It cant connect to my bcm.. what do i have to do with the cem? Same thing that you did, will it help?

Hello, I have seen your videos and I have the following question. on my C70 2012 Volvo, it's got those RFID-enabled door handles which means if the original key is near the door handle, then, either pressing the button, or pulling the handle, should automatically unlock the doors in case they are locked. Also, if you intend to lock the doors, pressing the black door handle button with the KEY nearby should also allow the doors to react and lock. After getting a paint job, I noticed that the right-door stopped reacting to this function. Only the trunk and the driver's door react correctly. Being from the technology side, I feel there is some RFID sensor that is either malfunctioning or missing for it NOT to sense that the KEY is within 30 cm outside the lock for it not to react. Pressing the lock/unlock on the remote control makes all doors react correctly. Do you have an idea how I can solve this problem?

No additional codes. Interestingly, I drove for several hours in 90 degree weather with the floor AC on and had no problems.

I always found the battery being in the back to be more convenient LOL especially if you are jumping someone

I have a Volvo s80 2001 that is going trough a battery drain it will turn on normally but then out of nowhere it just doesn’t want to turn on, I put a new battery and a new alternator but that’s not the issue would it probably be this?

Hello- just came across your video while looking for answers to what I thought were transmission problems on my 2001 Wagon, V70 T5. The wagon idles high, jerks forward while the car is stopped with brake on. Sometimes it shuts off as I slow down, before coming to a complete stop; I put it in park and it turns right back on with no problem. The jerking and high idling does calm down if I put it in neutral (while stopped). Mechanic has replaced several parts and took it to Volvo dealer to get tested. They said it was some kind of sensor in the transmission and that it would cost a lot to replace. I am confused, don't know really what it is but my gut tells me is not the transmission. Does what I describe sound familiar? Can you give me any advice?

My dash stoped working (needles , all dash lights) also my center controls such as A/C and heater wont turn on. Only the radio works. Turing signals and wipers still work but my driver seat does not work anymore. Could all this be related to the CEM? I have a 2001 V70 xc

Hi XeMODEXI just discovered your web on the internet as I am trying to get a solution to my car, I hope you will help me. I have a Volvo XC90 2004 model, the dashboard switches off after a few hours of driving and I wont be able to use the indicators, power windows, stereo etc but the engine will be running. Sometimes the car jeks a little bit. Could it be the CEM that has a problem?

great vid my situation is different my S60 doesnt start battery is good and all lights in the dash is working but wont crank cleaned terminals too but nothing all fuses are good i hear a click by the shifter and in the rear by the battery when i turn the key do you have any idrea what it might be??TY

Can you do a video for the 2006 xc90?

Hey guys, My 2004 XC90 was in limp mode so I disconnected the battery and pulled the ECM and CEM out. Pulled all the relay's etc out, sprayed everything with electronics cleaner and put everything back fresh and tight. Car started and runs great but now I have a SRS Airbag Urgent message. Is this a stored message? Is that normal after pulling a CEM?

Hi. What is E001 code? When putting my foot down on 2004 automatic XC90 it loses power and then I switch off the car and it's ok...until I accelerate hard again.

Hi, today stopped at the gas station’s ATM and turned my s60 II 2012 d3 off and than again turned the music on, so it played while I was away. After I got back, slipped the key into a hole and bam... blackout. No electricity whatsoever. Dead! So, after 10 min thinking I got ahead to the battery, took the both clamps off, waited 5-6 sec, put the clamps back on and bam... all the gizmos went back as they were before. Started the car normally. I’e never had such an experience in my 18 yo car possession life. Any hint?

I got my CEM about HALFWAY out... I pulled it foward and the tab to the car-center side slid out nicely but the tab to the car-outside side will not disengage no matter how much up pull it or try to wiggle it free. The white metal bracket itself (shown at 8:24 in your video) is flexing as a try to pull or push the relay housing / CEM. It's like they are welded together. WTF Volvo!? I'm guessing with the number of these that you pull, you might have a solution (short of removing the whole dashboard). Any suggestions?

so I just replace my CEM with yours works great except I have no low beams?

I have a 2001 S60 diagnosed by Volvo shop...as a bad CIM...for $1400,,car is wworth $2500....no ROI there so I found your site,... followed the steps removed the CIM replaced with same year and model ...and ran into the key code how do I re program the key to this new CIM .?? Serial number on new CIM ?? please advise James

Witch ones for the radio

i have v70 Volvo my signal light relay not working , can you show me we the relay which side of the dashboard

Hi by chance is the fuse for the brake light switch or tail lights there?

so I need to replace the flasher unit on my cem, the left turn signal is bad. which one of these modules would it be? thanks

my fuse box cover in the engine shows list of fuses on the "upper side" and also "under side". any idea where is the "under side"? the list shows "ffm8 - radiator fan - 60 mA" (which stopped working that I'm trying to fix) 03 v70 2.4t

I'm having this problem with my 2002 Volvo s80 2.9. do I have to have the CEM removed and sent to you? and How much it cost! please give me a reply. I like my Volvo but Just had transmission put it and it's now starting to be a money pit and I need my car!

I have 2004 xc90 with no start condition the rpm gauge doesn't read while cranking, other gauges work. It just lost power one day while driving, now it cranks but wont start. Only one other time i lost power while driving but recover on its own.I tried replacing the crankshaft position sensor but still no signal to cluster and the fuel pump can be heard working and all fuses and relays are ok. Could this be my problem?

Where are you located

I'm curious as to just how water gets in these. My 02 V70 is showing classic signs of CEM fuckery and I suspect it's why my sunroof suddenly stopped working and My AC no longer blows cold.

What should i do

Hi, I have this issue on my 2003 xc90 T6. Do you ship to I had the exact same problem as some of the other described below. Bought a 2003 XC90 in Dusseldorf and when driving it back home to Budapest, after the first 300km this problem started happening. Cluster off, windows, sunroof, break lights, indicator, transmission gears playing up, radio off and many others. Engine and Breaks working. If I turned the engine off it worked for 10 minutes again then again died. I limped to the first Volvo service station (Hanau) where they told me the car is very broken and they gave me 2 pages of error codes. I called the dealer in Dusseldorf, no help there. Left the car in Hanau and came back to Budapest. Now with all this new info at hand I am thinking of flying back to Hanau to bring the car to Budapest. Do you think the pc fan will do the trick for the 1000Km ride as a temporary fix or I need to pay for a new CEM in Hanau from the Volvo dealership (probably very expensive). In Hungary the repairs would be much cheaper. Other alternative is to bring it back with a trailer. Do you ship to Hungary, if so how long will it take to get here and when is the cost. (my emil is thomas.papp.eu@gmail.com) Many Thanks for your help.

Does the Volvo wagon have this in the same location?

If i get a cem from another 2005 xc90 2.5t. Will it plug in and drive while i send my original in to be properly rebuilt by ya'll?

Hi I have a 04 xc90 and I couldn’t remove the cem can you tell me where l have to push to get it down from the grooves?

Great video but where is the immobilizer located in s60?

Question: if you're just trying to remove the ecm, why do you have to remove all those shunts and fuses off the main board? Seems like extra work

That is exactly my Problem on my well in shape 2001 Volvo S60. who's repairing these CEM's! Any address available?

I have a 2004 V70R and i pressed the dtsc button, dash went crazy n instruments died. But it never turned off. Checked for codes and said "Communication error with tcm". I unplugged both tcm and ecm to clean the connections, once i plugged them back now it turns on and and only shows a dash instead of gear selected. And only drives in a "limp" mode. Like just stuck in a gear.

hello i would like to help you with a thing, i have a 2004 volvo xc90 with the steering wheel on the right and its signals are no longer not on the right panel that i controlled, i was told that it is a lighting relay but i don't know where It is . can you help me please nice

I have a 2002 Volvo S60 2.4t and some of the electrical components will stop functioning and at times they'll work. Recently the dashboard has stopped working and I removed it and cleaned it and got a check engine light, which is the only thing that actually shows on my dashboard. Do you think it could be the CEM?

Hi, I have 2003 XC90 T6, it experienced Volvo known sunroof water leaking issue second time last Nov, first time happenda few years ago. Now it has intermittent no start problem, starter and 4 1/2 years battery were replaced. The symptom is only dash light on, no cranking, no start, AC is off, headlight is on for 1 second, then off. Last time when I called AAA for towing (around 10 mins), I tried to start it again, it worked. If I use a cable to connect starter relay pin #30 & #87 directly (bypass ignition and CEM/ECM), I can start the car. It means problem happened between ignition, CEM and ECM, how to diagnosis it is CEM or ECM problem (I sas ECM is involved in start too)? Using hair dry for several mins to CEM can help (I saw it on your website)? Thanks

Can I send you mine so you can fix it and if so how much does it cost?

Need help with advice on CEMfor 04 volvo xc90 will this video work?

2004 XC90. After 2 hours I get three engine skips followed by BRAKE FAULT followed by BLANK instrument panel, car in limp home. Shut off car, wait, turn on with SRS warning. I pull 928C, 530B and 00D5 codes. Once I clear them everything seems to reset. I can do small trips over and over, no issues. Only happens on long drives. CEM module?

I have a 2004 xc90 while driving I hear a click and like a reset then again the brake lights abs on the speedometer goes down and loss power. If a turn the ignition switch back and on it goes back to normal.

I tried the fuse #8 and that did not do anything, the fuse was good. I have appointment tomorrow at a shop , will let you know what they find out.

Slt j'ai un Volvo v50 qui ne démarre pas après diagnostic j'ai la liste des défauts suivante DD01,DD11,0128,013A,E003,0071.J'ai besoin d'aide SVP

Hi, I'm looking to get some help with my Volvo V50 SE D (E4) 1998cc . I was driving this morning with some light rain coming down when all of a sudden a message apeared on my dash (Brake failure stop safely) with the (ABS, engine management and anti skid symbols displaying). I had no acceleration what so ever, I pulled over and tried restarting. A message then displayed (Immobiliser see manual ). If someone has any information on fixing the problem it would be greatly appreciated. Thanks in advance Jordan

"remove the electrical connector with a ratchet". The screw turns around infinitely, trying for hours, found no way to remove that cover without breaking it. So it broke. Still couldn't find a way to disconnect the power connector. The hard parts are those that go quickly in the video when the guy goes with his hands in front of the camera so you see nothing. Getting the CEM removed is 99% of the job, placing a heat sink is easy.

Hi could you share the link to the sheet

Can customers send ecm to you to be fixed ?

I have a car where there's no AC, radio, power windows, wipers, exterior lights for 5 minutes on a cold start. After 3 minutes of idling, the AC starts, after 2 more minutes the wipers and lights start (after an insane amount of clicking noises in relays all over the car). Is this the CEM? is it enough to change relays or does the whole damn thing need replacing? I've been informed by Volvo Dealership that the DIM needs replacing (that's like 1100 gpb) I believe that's not the correct diagnosis. Please enlighten me :)

Did the C.E.M. have to be reprogrammed?

I'm trying to remove the cem out of a 2003 Volvo xc90 and I cant get it to come out .

Hola amigo yo tengo un volvo xc90 y me esta presentando un problema eléctrico muy grande que mantiene las luces encendidas a toda hora y los intermitentes no funcionan haaa y me descarga la batería en poco tiempo

Mine looks NOTHING like this its a HUGE 'L' shaped module so Ive given up - I will have to strip out the whole dash :(

Volvo XC90 não funciona como resolver

I have a Volvo s80 2001 and it keeps shutting down on me when I accelerate and then let it roll

Что-то я не понял, открутил, закрутил, и всё? Как решить?
