SYMPTOMS OF A BAD ECM (ENGINE CONTROL MODULE)

I bought a 1,000$ scanner to reflash my ecm. Dayum! Now I have a thousand dollar scanner. Bought a new ecu. Dayum!! Reverse polarity from your battery will do major damage.

Always check the battery and polarity first. It's easy and fast.

Let me explain. I was out and about...Left one store and went to the next right across the highway...Leaving the 2nd? Every light on the dash known to man was on. Took forever to start...Limp home? More like pray I get there.

Here we go...It's NEVER the ECM...EVER.

My 2012 Chevy Traverse when you turn the ignition to start it and let go of it it sounds like you're holding the ignition switch I can turn it off and then turn it back on and it will start

ECM, PCM, TCM it's enough to drive you crazy...

Pauly Shore 😂

That's exactly what's happening to me with my car - new sensors, relays, connectors, etc. and still getting varied error messages.

Great😂 video

my car have all this signs,and also p1351 code on odb! do i have to change all acm,or need to see where the problem is located? if anyone can advise me i’ll appreciate it

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!

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.

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

I have a check engine light and portable scanner red
P0606...ECM MODEM MULFUNCTUION, tuk it to the service and thay said that instaling new software would fix it.

My ls460 which is know to have PCM issues in the 2007s have amlost all of these syntoms it says I have miss fires on the whole right side of my engine but it idols fine but has a visible miss fire in the rpms during acceleration only getting it up to 3k rn no higher because I don't want to break anything too expensive... My power train is under warranty still so I'm not to concerned but I'll update if that was the issue

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?

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 ?

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.

So this dosent sound like my issue so it's wiring issue I'm having

Can a bad ecm send a vehicle into limp mode?

My car is experiencing a lot of these problems but my error code is P0777.

PLEASE HELP ! i have a error code P063400 " CONTROL MODULE INTERNAL TEMPERATURE 'A' TO HIGH " i replaced the ecm and checked all the wirings and vaccum pipes changed all the sensors still the error does'nt go away and the turbo wont even activate tried everything still not able to solve this ! car brand is vw polo

Dude I just replaced my ecm on my 91 firebird it fixed it for a month it just quit running and I can't get fire at all and my fuel pump quit too and my speedometer stopped also

What if my truck only runs correctly when my hazard lights are on

Sometimes it can be fuse’s too because people don’t change them out at times.

Bullshit

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?

My 2013 Ford Explorer has P0219 code help me😊

Great video!
I replaced the Runner control on my 08 Jeep Compass located on the manifold (3 screws 1 electrical connector) I put everything back together and now it doesn't start. Can it be the ECU? ANYONE???

Must be the reason why my throttle body want open

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?

My 2000 mustang shakes SO bad and just not started to not shift into 2nd till it almost red lines, but if I put the shifter on 2 it’s just fine

U save me and my Dakota thanks a lot

Oh I'm here having a Monumental day all right! My fecking car died!

Could you disconnect the electrical connections to check for corrosion and if corroded spray some electrical contact cleaner ?

Which country

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.

I have every symptom 😂😂 ecm come in the mail tomorrow

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.

He so for all the chips with trucks and mechanics around to help.. can someone please help me locate the ECM on my o2 chevy silverado 2500HD 8.1L gas engine!!!????? Thank you💙

I’m getting a code P0883 Can that be a bad PCM?

SOUND LIKE MY ISSUE.. MY 1996 F150 STARTED DROVE 100 YARDS.. THEN STOPED.. HS SPARK HAS FEUL, HAS AIR... TURNS OVER BUT DOESNT BARK.. JUST TURNS .. EVEN WHEN I SPRAY STARTING SPRAY , WONT START... HELL IT SHOULD.. SOO IGNITION ISSUE..

OK

ok

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

I had the code P0505 bad idle air control valve sensor for the longest. I cleaned the throttle body and replaced it 4x idle air control sensor but I still get the engine light with rpm going up and down. 😢😢😢 I think it the ecu

i have a genuine question, if my current ecm has gone bad and i buy another oem ecm do i need to do any programming or tuning since it’s a new oem part?

can it cause the timing to jump ?

My Toyota Rav 4 2000 yr with a 2.0 litre petrol engine when run upto normal estm temp thr green Econ light comes on yhen thr rngine misses runs rough sny ideas whats causing it
