Volvo XC90 2005 immobilizer problem
1993 Chevy Lumina 3.8L dies while driving. Starts good runs good for 15 miles at most then dies. Will not restart right away. Have to wait 30 mins to an hour then will start up fine and drive fine for another 15 miles and die again. Its not overheating. No check engine light. Have changed fuel pump fuel filter plugs wires. Sensors would trigger check engine light always? Actually its SERVICE ENGINE SOON on this car. Unless there is also a CHECK ENGINE LIGHT thats malfunctioning. that would make sense.
Hey EasyAutoFix!, I have a 2019 Toyota Tacoma with manual transmission, what kind of symptoms would I be getting from a bad ECM??
Bro you sounds super baked lol
My ECM was causing me a misfire on one cylinder and needed to be replaced.
If one is watching this video, chances are they aren't having a monumental day..lol..
Lmao
It’s weeks
@@great1fromza234same brother
Me
Yup
This video literally just explained everything that is wrong with my car thank you so much bro
Same here..thanks
Literally.
Same here too
😂😂
Same here, my mechanic is on it now! Thanks for sharing the video!
Bro my car probably has every light on 😂😂😂 looks like Christmas in my car 🚘
Yea mine to 😆 🤣
Damn did yall get it fixed?
@@baconatorsupreme5165 a lot of people don’t for some odd reason
Same here
I thought it was just mine 🤣
Quite interesting..I have all that you described in the video! I own a 05 Explorer 4.6 with 260k.. I still have another 40-90k left on that truck!
Thanks this has been helpful.
Spent too much money on the wrong things, thanks for this video! Going to get the ECm checked and replaced
Same here smh
I changed oil pump, water pump, air flow sensor and as they downed the engine many other stuff for wear and tear. Eventually they say ECM maybe is down and they have no clue to fix it. Now I’m thinking is it better to go Ford Workshop then outsiders for experts is missing and no solution to the problem.
So my car has Alzheimer’s
Exactly 😂!
Lol
GOOD ONE.
Yes just like sleepy Joe Biden lol
Lmao
You are awesome! Did diagnosis for my harrier no code but sugg. Electrical
Jackpot, my car has Loss of acceleration + bit hard shift.Oh! Lot of love from Bangladesh.
May lord God restore all success and happiness to you❤
Ditto
Thank you so much.Very helpful video.That s what exactly my Chrysler minivan is doing. I ll replace that engine modulo control box .
Great video. Exactly the symptoms of my car
This checked all the boxes . Thank you
Simple and to the point. I think this is the problem I’m experiencing with my 2004 jeep. I heard that Jeep’s are bad about that. I’m driving and stall out. It’ll start back up, after a time but I’ve changed the TPS, the coil packs, the oil sending sensor and still my jeep dies, randomly! I’m so frustrated.
Did you change the crank sensor? My 1.8T Audi would cut out when warmed up. Took about 20-30 mins to cut out. Took 45mins to cool down then it would start
Excellent video,remember this, the newer your car is the more unlikely scenario that your ECM is bad unless it was in a flood or some catastrophe like that, a lot of ECM's have capacitors in them and capacitors have a lifespan like everything else,some of these capacitors control or "help" the processors make decisions and if they are leaking their guts out (which they do as they age) then you start having problems,they start minor and get worse as they get older and leak some more, this usually happens 10\15 years or so in the life of the car, less these days because the electronics are cheaply made.
These problems need to be addressed promptly as the stuff they leak is corrosive to the board and what started as a simple problem will take out a nice chunk of the board overtime and cost you much more in the end,the only way to find out about this is to have a visual look at your ECM,you dont have to be a scientist or some super duper electronics specialist to conduct a visual inspection,it will be screaming at you as soon as you see it,sooooo if you have been replacing things you thought were bad and have checked and double checked everything and you still have issues more than likely its your board.
Thx, will chk it out 👌👍!
great channel straight to the point
Big brother thank you very much for making this video, am very grateful. You are Blessed❤
2009 Kia Sorento, check engine light came on months prior to this: had occasional symptoms of possible clogged catalytic converter or even maybe fuel pump issues, drove it home one night, no new issues, next morning it crunk up but wouldn't go in reverse and acceleration in drive was very minimal and no power. Drove about 4 miles and it cut off, popped hood and seen that the transmission fluid and blown back out the dipstick, added more fluid, cut it off and back on and it was as if nothing had happened at all. Drove about 2 miles to store, got gas, drove about 1/8 of a mile and there was a grinding sound if you will, car cut off and would not start back up (acted like it had a dead battery) I let it roll in neutral to my yard, where it remains. It wouldn't crank back up then, 6/7 hours later I try to crank again and it would as long as I sit in the gas pedal. I check and confirm all fluids are good and leave it be for the night. Next morning it cranks up with no problem at all but now when I put it in gear it won't move, revs up, but in no gear will it move... Any advice on what I have going on here?
crankshaft sensor or some sensor. start at the bottom
Thank you! Should've watched THIS before putting it in the shop! My van was sitting in my yard waiting for my turn signal relay. Ran just fine before that. Replaced the relay went to start it...NOPE! Thought it was the fuel pump, just got off the phone with the mechanic and he said-"well, it's NOT the fuel pump, sounds like it's the ecu." Dang it! When I tried using my OBD reader it malfunctioned, well....that explains it!
i changed ecm+cts+maf+fpr+o2 both sensors+ exhaust system+fuel filter+plugs+wires. finally running great.
What car brother?
@@OrlandoRodriguez-lz7df don't just love it when no one ever responded to your question ❓
@@peacepoet1947 lmao 🤣
Literally the same thing and all it was, was the damn ecm😂
@@bigremy2099oh boy it looks like I’m on that road. Ordering a ecm this week 😬
When i change the ac temperature, or turn on and off the vehicles features, even usb plug on and off my iphone/somebody else’s iphone, the throttle and brake pedal harden or soften. It’s pretty weird, could it be ecm issue?
Having the same problem w/my 05 Ford focus zx4. Was driving home from work, car just died on me. Tried to start it again, couldn't. My miles turned into dash lines on my odometer. Could be the ecm. Any help or suggestions would be appreciated.
I haven’t yet replaced the ECM, my van 2013 Dodge Caravan starts and dies already. I’ve replace sparks, coils, rockers -lifters, and alternator I still get every code relating to misfires and slow response time in camshaft. I do have a used ECM I pulled from the yard. How would you tackle this? Tried clearing the codes with the scanner with no luck. Please any help would be so appreciated.
Can sensors confuse the ecm/pcm? Like If i fix my throttle actuator codes will the ecm/pcm function as normal?
When do issues with the ecm start to pop up? Im asking cause I bought a new car and within a year, Ive had it fixed for malfunctioning ecm. Then afterwards, after months in, it happened again and I’m just shy of over a year.
Could a bad ecm trigger a p3400 code on a 2009 dodge ram 1500? Tried replacing throttle Body and still having issues. I'm also having Hard shifts when moving from park to drive.
Man thanks for all that. I have a 91 LS 400 and I've had engine stalls and loss of power/acceleration just out of nowhere. Now I have something to fix this problem. 🤞 appreciate the video. Good work. 👊
Any updates?
Hey man, did you replace the ECU on your car? I have random loss of power on my car when it's warmed up and it loses power even more on these hot summer days, the car is Audi A4 B7 1.9 TDI, I've checked and replaced everything, injectors tested, new turbo, new N75 valve, blanked EGR valve, intake and exhaust clean, new MAF and MAP sensor, new tandem pump, checked vacuum hoses and still I wasn't able to solve the problem, regular maintenance is done even before it should be, engine timing also fine, all filters changed etc. Let me know if replacing the ECU solved your acceleration problems, because I have replacing my ECU on my mind soon...
Haven't changed out ECU. I understand there's a guy in Dallas area who works on/replaces ECU's. But I don't know it thats specific for LS 400's only. Man you've done a lot of work to your Audi. GL
could be an intermittent loss of ground
Long shot but would anyone know if this would relate to a 2012 GMC Sierra I’ve changed the throttle body tps and the acceleration pedal and it was fine for a week and at random my gas pedal will quit responding and it will run super ruff you can pull over turn it off and turn it back on and run fine for a while then do it again
This video was so helpful I had no idea what the ecm code on my car was , and this video describes all the symptoms my car has. Awesome video, well done. 💯
did you fix it ?
Ya same here, if had trouble with it for a while. Ut I didnt know it was about the ecm
Feels like doctor says what is happening to us
@@sbkhatri 😂👍
X2 mines on the way. 2010 Hyundai sonata
if wire from engine harness caused a short but short was corrected could this be a result of no start and blown ecm ?
Hey would the DME from an e46 318i be compatible for a 316i,both within the year of 2002-2004,same n42 engine and DME number?
Could you disconnect the electrical connections to check for corrosion and if corroded spray some electrical contact cleaner ?
Thanks bro really helpful 👌 👍

I've been jump-starting my car a lot lately and this week I experienced new problems. The tach needle won't rise to idle, the instrument cluster won't light up, the transmission shifter stays locked in park, and the engine dies when I take the jumper cables off. I've replaced the alternator, and my 2-year-old battery has been a pos, so I'm replacing that too. You think its bad ECM, or lack of power??
This is describing almost exactly the problem I'm experiencing except for the shifting problems.
Engine light code reads as an oxygen rich problem, but after switching out the ignition coils, spark plugs, both oxygen sensors, air filter, and also checking for air leaks...the problem persists.
Then i remember getting a high pressure car wash, and water was leaking into the driver compartment. Thats when all the problems began with engine light, reduced power light, and traction control lighs all turning on....This is most likely the problem.
How did u fix the problem? Having similar problems
He said ECU is most likely the problem @@isaiahbaah515
Hi pls suggest what to do i have this error message p0606 component y3/8n4 fully integrated transmission control unit is faulty.. can i service or have to replace the sparepart
Thank you for this video !
Hello,Circuit Intermittent , sometimes when you starter the vehicle check engine going on with VSA, nothing different after update , already replaced the crank shaft , the problem is still , I try to take off the cable from cam shaft sensor and I drive the car. It's nothing gonna be happen no a check engine going on , the pcm has been delay to see I take of the jack from the sensor so what do you think the problem? Thank you.
My fans keep spinning when the car is turned off and it drains my battery … I changed the coolant temp sensor and checked for corrosion can the module be the reason for this ? I usually just pull the fuse after I park the car so the fans don’t spin. It’s VW GOLF
I have a 2007 chevy suburban .it started at sometimes and got worse, I would loose 1st and 4th gear. I replaced the shifting solenoids and checked the wiring in the transmission. And now it's all the time I only have 2nd and 3rd. Chevy place wants me to by a new transmission. I also think I have fase code popping up. You think the transmission problem could be the tcm,or ecm ?
Okay so I have a problem with my 2000 mustang GT, it won't start it has fuel it has spark it has air and I've checked the grounds they're fine, but my car still won't start it will start on starting fluid but won't keep running, starting to think it's my ECM but I don't know I took it out and looked at the motherboard it all looks fine no corrosion or anything could the ECM just gone bad?
I have code P0505 on my truck saying "Idle Air Control System". I replaced the Idle Air Valve and still have the check engine light, any ideas?
Wow . Wish I would’ve seen this video sooner . Now the car won’t even start and these are all the issues I had up to this point . I changed so many other things and spent money on so many other parts .
I need help with my 2010 Skoda Octavia 1.9 tdi combi. The glow plug light initially kept blinking while driving and so I finally had an engine shutdown. Engine doesn't start anymore, glow plug light doesn't come on again, obd2 not communicating with ECU. Gateway changed and nothing changed.
I went through this with my 2011 Altima right before Christmas of 21. It took me a couple of weeks to make the educated guess that my ECM was bad. It kept throwing P0705 Shift Range sensor but I pur 2 new ones on it and didn't fix it. I even did the multimeter pin test someone recommended on all 3 and they passed so after much research I got one from a place online (cheaper than going to Nissan) when I got it all installed the car wouldn't run.
I called them, they asked me to see if I can find out why it's not running. I said way ahead of you, it's not getting fire to the plugs. So they sent me a shipping label and asked me to send both of mine back so they could clone the original and flash theirs and send it back. When I got them back it worked.
I never had another problem until yesterday. I went somewhere and when I went to go home, it's in limp mode again just like last time. When I checked the code, same damn code P0705😡 I still had a new switch and just for aguement sake I tried it and just like last time, I think it screwed my ECM again. It's only been a year and a half since I fixed this and about 4000 miles (my car only has 60 000 miles on it and I bought it new) at this point I'm ready to soak it in gasoline and burn it to the ground, I'm not gonna keep fixing the same problem at the ridiculous expense that frequently. Bought it brand new and these problems are getting ridiculous. I'll NEVER own another Nissan again, I don't give a damn if they paid me to take a truck load of them.
Have you heard of ECU xchange out of Florida? wasn't sure if thats where you sent your stuff to, they are really solid people and might be able to help you out, you could have a bad ground thats messing up your ECM's, not trying to be argumentative and i have never owned a Nissan in my life but all cars are the same pretty much,they all have a quirk that causes them to have issues,granted 60 thousand miles is nothing,you shouldn't be having any problems and it sounds like your mechanically inclined, sorry for your troubles, when the car is not running right is a major source of frustration,been there many times.
Question, so I test my ECU Relay and fuses when ignition is off and nothing is lit, but when I turn ignition to on ECURelay and Fuses light up...I that how it's suppose to be and does my ECU good?
I was having a problem with my car it’s a 2005 Nissan Altima 2.5s and it got a engine code for P1065 is this a code that the ecm throws? Please let me know
Hi I am a fan and watch your videos. I Do have a situation and hoping I get some direction.
I have a question on 2004 suzuki that cranks but not start , and no comm issue and but have proper ground and power on pins 4,6 , and 16 on the DLC . Also ECU is not grounding the control wire on the fuel pum relay control wire, therefore no power on fuel pump. However, I noticed igintion fuse that power fuel pump also powers the ecu and the spark plugs, that wire if I cut it from the fuse now the cut wire stilled attached to ecu shows ground. with a light test This supposed to be power but shows ground when disconned from the fuse does this mean there is a short in the ECU? Also the ECU is not grounding the control wire for fuel pump relay as I said. Would you say the ECU is shorted?
I have a 2018 Chevy traverse when I’m in auto stop my stabili track light comes on sometimes my parking assist too and powder steering reduced service light too! But when I turn the car off they all go away. I got my ECM replaced less then a year ago. Could this be the problem? The ECM?
OBD Fusion figured out my problem. I’m glad it told me that my battery was dead but now I know that my alternator
Thank you 🙏🏻🙏🏻
Looking for any help=my 05 camry no start no crank but when I turn the key on the only instrument panel lights that light up is engine light and seat belt light.
What about rpm surge when clutch is in. My motorcycle has rpm surge when pulling the clutch and idle rpm is also higher than 2000. The service centre says their diagnosing software says faulty ECM.
My cars lights on the dashboard kept turning on without a key, then my car wouldn’t turn off, I disconnected my whole Ignition switch, and after connecting the battery it still lights up, finally got a code that said short to ground 3/4 of the fuel injectors, and fuel pump is open, but Removing fuse #3 small red 10A turns computer off, does this sound like an ecm issue?
I replace the engine on a 2009 blazer and i have bad contac on battery post and i blame on the starter was only clicking i use a jump box puting 24 vlts to it and then cranks but not with 12vlts now i fix the problem on the negative post but now cranks only and never starts do you think i damaged the computer already???????
Can a weak car battery get a po685 ? I have no symptoms other than occasional check engine light that comes on and clears on its own. I did scan and got the code po685 could it also be a faulty relay in the fuse box?
I have all those symptoms except starting. However, I have one that you didnt talk about. One day all my dash warning lights came on all at once then they went back off, except for the engine light. Then I noticed, while on the freeway, that my speedometer was not working, and while I looked at it, it shot back up to where it should have been (about 70 at the time) could this also be ecm?

Man I’ve got a 2000 Lexus LS400. Guy I bought it from said it might need a new ECM. It’s been throwing a bunch of codes. I just replaced the knock sensors and the knock sensor harness, VVT Solenoids, and I’m about to replace the connectors for those too. But the CEL comes on and it’s the same damn codes. Could be a bad capacitor on the ECM right?
I have a 2008 Ford Explorer 4x4 wheel drive 161000 miles on it. Basically, rebuilt the whole engine. Having trouble with the engine light and it's showing all 4 02 sensors bad I changed them all including the purge valve EGR valve air flow sensor I'm losing about a 100 miles a tank of gas. I rebuilt the whole engine all the Cam chains fresh tune up I did get a new ECM computer 2 years ago but that guy went out of business cause it was under warranty so now I gotta send it to some place to get rebuilt for 600 bucks. Other than losing fuel and the engine light staying on it, it runs and drives fine except for the gas.
my car wont start and the guages dont go up.chevy impala 2011
i was driving and out of nowhere all the gauges went down but the car still was driving good.what can be the problem??
So.....I'm on the highway going 60 and I step on it a little to get around a semi and the car jerks hard into a higher gear(automatic trans)but still hits 80mph is that possibly a faulty module? Not a transmission issue?
Can it cause a purge solenoid to stay open? I have a vacuum leak through my purge valve bc it’s stuck open, got it replaced but it continues to stay open… I don’t know what to do
My truck would not start after it sat for 10 minutes when I turned the key the brake lights on cluster came on but nothing happened. The starter did not work nothing. I reset the ecm and then the truck started right up is my ecm bad? Its also throwing a code that my cat is bad but reset it and didn't get a code until today a week later but I had to reset the ecm to get it started so no idea if it was the same code or another. The truck wouldn't start until I reset the ecm. 1997 f150 4.6
I had burning ignition coils. Also the obd scan tool cannot link. Getting errors!
My 1994 Toyota Corolla started to stall & eventually unable to pull out my driveway without it turning off or just not warming up and all the lights turn out & cant rev , HOWEVER I let it sit for a month or 2 with unplugged wires & one day I turned it on and it took about 10-15min to warm up after that I could drive around but I didn’t go far just the neighborhood & gas station it’s weird cause I could not even drive before now she warms up n sounds decent , Should I still replace the ECM Module ?
My car is 2015 Ford Fusion SE 2.5 L six speed automatic transmission. It’s sometimes will crank sometimes won’t. Also will die when I do start it. Could be ECM ? Weird thing is that only tire pressure fault light and steering wheel assist fault service required light will turn on. Also why do Auto Zone is able to read codes and OReillys doesn’t?
How about power steering my 08 cadillac cts has power steering problems after the start of vehicle once you go down the road, gets stiff, had the power steering checked everything was fine, it was plugged with a scanner and was told the computer could be the problem, is that possible and does the pcm have control of the power steering if not do you or anyone reading this have knowledge of how many modules the cts has?
So i have a 06 town car and the wrench popped up and car stopped i waited a few minutes and had to start it again. Would this be a ecm? Also i do have engine light on that is giving me a o2 sensor code too.
Intermittent all crank nonstart is an ecu problem? Changed fuel pump and relay already but still happening
Crv 2000 rough idle want stay on atleast i run the gas for min then went stop at light it has cut off "lights" that come on is the oil and battery any ideal wht this cld be
I have no check engine light on but when I move the wires that go connected to the ECM truck shuts off, any tips or any idea what can it be..
I’ve got no engine light but the radio keeps turning it self on when the car has been locked, also smells of fuel & the clutch has been playing up (could this all be linked)
Thanks!
How do you check ecm function? Do you have to send it in to a 3rd party?
If my car is tuned is it possible it can just throw this code because it's not used to the tune on the ecm? And if so if I clear should it be good? No problems starting up at all.
Can bad ecm cause p2138 code I've replaced everything from pedal throttle body and wiring pigtail, it still goes to limp mode and throws same code
THANK YOU SO MUCH.
Beautiful video mate
I appreciate you!
I think this is what im going thru about the acceleration, if is this can I buy and replace it myself or it needs a dealer? GMC Sierra 2010
After battery died on my Chevy I replaced it. But a idle or low speeds it would die out. It fixed itself after a while but could this be a bad ecm?
Hello I've done about everything with crank no start and I'm wondering if it is my ecm. Can this be a symptom too?
my alternator went out and the car died 3xs or i meant the power went out multiple times completly dead...will that cause damage to ecm because my enginelight flashes but when i turn my engine it goes away ,my shift works but it stays on 4-5 i afto use the cvt to shift it, and i notice it sluggisjh everything works but i really think its a sensor or ecm..ever since it happened these problems occur, nd my alarm doesnt sound off anymore ,my radio also falted till i switched a fuse, i think it killed the fuses
Wow. My starter went out and my alternator was acting up, replaced both of them had no codes prior, but my idol was choppy and my car was stalling. Finally get it started again and it’s throwing p2195 and p0500 codes but I reconnected everything and I checked to make sure my mas was connected. Everything looks good. Probably going to take it for a tune up play stupid and see what they tell me cuz I don’t want to mess with the electrics of my car and I’m not jumping to conclusions about my ECM being bad
I think I’m having the same problem what did you do to gix
Idle
Can this also throw throttle position sensor correlation codes, causing reduced engine power light
Have all these symptoms yes also can this ECM cause the plug in for the trailer stop working?
I have check engine light, blinking cruise light, and shifting issues. Then I reset the ECM and they go away, however then later after driving a while they come back. So is my ECM going bad?
So. I have all this and my gauges were going haywire as well.. now it won't start... ECM or back ground connection?
06 Ford F-150 p062c internal vehicle speed module is is my ecm if so why only the 1 code y not more
Tanks it was a lot help
My 99 Isuzu Rodeo 3.2L has been having several issues. 1. Hard shifting and it will not shift into overdrive. It actually seems to go back into 2nd when it should go into overdrive. I'm riding 2500-3000rpms going 50mph. It seems if I get up to 70mph and 3500rpms and hold it long enough something lets go finally and then rpms drop and the check transmission light starts flashing. 2. My Rodeo also has an issue with starting then immediately stalling. It used to be every other time I'd start it up. Now it's nearly every time except on cold starts. But warm starts are ridiculous. Occasionally it'll try to start without a single crank, but stalls. And then other times it cranks and cranks and cranks and still won't start until I give it some gas. On these starts the idle is up and down and up and down til it settles between 500 and 1000rpms. On occasion it'll stall out while idling but not driving. That's even on cold starts. It just does whatever it feels like. There's no vacuum leaks that I can find. There are no codes thrown for any of these issues. None. One person did have a scanner tool hooked up that showed a "pending" code for an O2 sensor failure. But now 3. My 4wheeldrive suddenly stopped working too. Doesn't engage, the light doesn't even come on when I hit the button. So do I have a damaged ECM or PCM? Is there a difference? I think my Rodeo's brain is called a PCM. Any suggestions would be fantastic. I'm about to drive this off a cliff with no insurance. That's how frustrated I'm getting.
Did you find out the result?
Hello I’m really interested
I have an golf TDI 2015
I think I fried the ecu
While removing the battery
I'm having issues with my 05 nissan pulsar. The cam and crankshaft sensors have been replaced, but now there is no spark. Sometimes it does turn over and sometimes it doesn't.
Thank you bro.
2005 Silverado 5.3. what abt your cooling fan cutting on when truck is off with brand new relays.

and thank you very much!
May I ask i have a 1996 chevy suburban 5.7 k 1500. Starts and runs like new unless its summer time. Turn it off to run in the store and come out and it won't start until the next morning,fires right up then! The fuel pressure is perfect and it has a new distributor,plugs,wires,coolent temp sensor none of wich fixed this issue. NO check engine lights on! In the winter months this problem goes away. Thanks for the advice!?👍👍
I tried an obd2 scanner that gave me this error code. But my check engine light is not on. No notifications on my car’s dashboard. Is that possible?
My 1993 Buick regal keeps stalling no check engine light just a check Gage light fuel psi 40 with engine on 35 psi
Does anyone know if the ECU controls detonation and if that could cause engine knocking, even temporary knocking where the engine could knock for a minute or two while warming up then run fine ?
