As you look at the box, the left module is the actual ECM (or ECU) while the right one near the engine is the TCM (Transmission control module) that appears to work for both manual and automatic transmissions
Just wanted to update. Cleaning the transmission connectors on the connector tree on the driver side towards the front bumper with deoxit d5 made the code go away. Back to normal as far as I can tell. I would absolutely recommend anyone with this code try this FIRST as the cost is only about $15 and anybody can do it. The connector tree is near the driver side front headlight, and they are all oriented vertically, so water can easily collect on top of the connectors and soak down into it, causing corrosion. As an additional bonus, you can use your extra spray cleaner to clean your battery terminal or any connectors you ever mess with in the future, and even clean your turn signal switch stalk if it's acting up.
@@Peppermint1 I forgot what it was but it was a transmission control module code. Researching the code online showed potential repairs as replacing and reprogramming tcm or replacing shift sensor. Thankfully I knew I had caused the code by introducing water into the engine bay, and back when researching it led me to your video. Most likely was whatever code you discussed on this video
I have a 2009 xc90..I can be driving and all of a sudden my vehicle has no power..i can step on the gas and it doesn't do anything. it does end up coming out of it quickly though. I can turn my car off and turn it back on and it seems to be out of it. I have vida..all it came up with for codes are p1719 and ecm-p001268...any idea? Thank you
Thank you for all your video, I took out the little fan and applied 12v red+ , black -, so the airflow direction is blowing air into the box. But when I put back the fan into position, I can't feel the airflow? Previous owner never changed cabinet filter. I changed it once I got it. So could it be any clogging behind the firewall.
I did wonder too about the air direction. It's not easy to measure it - may try keeping a napkin close see if it suck or pushes it. My impression was the fan was actually pulling air from the box towards inside the cabin, which would perhaps make more sense, otherwise it will have to fight against the vacuum from the cabin blower. I'm not aware if the fan duct goes behind the cabin filter, I would guess it enters the climate ducts before the filter.
@@Peppermint1 I will double check with wiring. I encounter the ECM or CEM overheating issue. Dash shut down, but still running. So I wonder, for the ECM the cooling fan is not strong enough. Try to put a temperature controller there to monitor the temp.
@@Peppermint12004 V70, 70k, Basically like online many people described: A/C not working, All meter not working, the alarm system not working. Very Rough driving. It is because CAN bus failure. so the CEM and other parts can't communicate
@@calebandrachellezhang3597 There might actually be several separate issues with the car. AC not working can be a problem with lack of freon or too much clutch gap at the compressor or faulty cabin temp sensor. Alarm system is caused by failed alarm siren module. Dash gauges may be caused by the common DIM failure but mostly 2002-2003 cars were affected - possibly early 2004 if they have similar dash. For other problems look under the dash see which model of CEM you have. If it has many small fuses on it, it's the one that gets water leaking on it from a faulty seal under the windshield. If it rather has like black small relays, it's the earlie CEM model which is not affected by water.
I don't. Here's how to try removing the modules - battery disconnected of course. Also remove the ignition coils see if there's water on the spark plugs, soak it up with towel without removing the plugs th-cam.com/video/pqCzHmM03mU/w-d-xo.html

Hi mate! I have following you since years, but never attempted to ask you. May you help me? I have replaced everything in my 2006 XC70 gearbox even valve body.

It thesame as i experiencing now with my volvo s60 2001. My mechanic told me the problem is the tranmission gearbox. Because when i change the gear from 2 to 3 then acceleration is not as it should be n the arpm going crazy and thesame when i change from 5 to 3 i feel no power at all. I look at it if the is wet or so.
It's automatic ? What you describe sounds like the transmission is slipping in the 3rd gear. May be because a garage removed the top 27mm bolt thinking it's a refill hole, or simply because the 3rd gear band is completely worn.

I have a 2002 volvo c70 , it has 200,00 miles, anyway its doing something weird when I put it into drive it sometimes double clunks rather abruptly , sometimes it's just a double bump that's not a abrupt one, when it's cold it doesn't do it, and sometimes it depends on the way my steering wheel is ( what way it's turned) other than that it drives pretty good , everyone in a whole it shifts a little weird but not major mostly if I gas it too fast not sure how to explain , the mechanic said it was my transmission , it shifts smoothly MOST of the time , the mechanic would not even bother w it, I haven't had it long and truly love it already but I'm not sure what to think it is, the mechanic seemed like maybe he had another car he would have rather worked on🥴 any thoughts? I have no clue about cars but am wondering if I should just drive it into the ground like the mechanic said
That's what's happening to mine, and the guy before me poorly maintained it. And I hoped after changing all fluids it would work like new but when shifting to 3rd to 4th gear it's starts to slip and mis fire. I'm not sure if it's ECM or the transmission wear and tear on gears

Normally repair services for electronic modules will try to salvage yours. It works most of the times. Xemodex in Canada is expensive, there are other electronic module repair services on Ebay. In rare situations where it really needs replaced, I think Xemodex can give you a used CEM already programmed from your old one, but they are not cheap. And Volvo will only reprogram if you buy a new unit$$$$. May also have a look on this blog, at the beginning volvos60xc70xc90buyersguide.home.blog/
