Replaced the transmission control module on my 2002 dodge grand caravan work van due to been stuck in limp mode 2nd gear, after install the problem was still there and was disheartened, more research led me to realizing i had to reset the TCM and then i came across your video, Initially i was skeptical but gave it a go, IT WORKS!!, not only does it work, its works better than ever. Thank-you so much for the information
Damn bro how much was the new transmission control module ? I had my check engine light come on, took it to autozone, n dey said I needed a new one. They were going for like $600-$800 so I needed to find another way 😂. I found out about resetting the cars computer, so I did it (and also changed my transmission fluid because it actually really needed a change) n now my car was running great. But about a week after I reset it, my gauge that tells me if my car is overheating or not, isn’t working. I’m gonna do another reset just to see if it will fix but I’m not sure
Check your coolant temp sensor sometimes the sensor goes bad sometimes it's just the pigtail that goes to it
After replacing my battery in my V60 2012 the car infotainment system vent totaly crazy. Nothing worked, every fuse was ok. The car had around 20 error codes. So i started searching on web for solutions and i came across this video. I must say i was very skeptical. Had nothing to looze so i tried it. After i shorted the cars electric system with battery disconnected, and then reconnected battery the car was normal again. Thank you very much!!
What symptoms did your car have before you did that??
What the hell is a V20? A Volvo? They have a completely different electrical system than the Chevy truck in this video and doing what is did accomplished nothing except perhaps a better connection from the battery to the alternator and cars electrical system. It is no longer B+ to the dash, it is serial data thru one wire and some two wires twisted 9 times per foot to prevent RFI. Don't know what that is...Stop! With battery disconnected & jump positive to negative is simply drain capacitors which is fruitless, waist of time. From 1998 and newer, the dash or instrument cluster (IP) has power, ground and class-2 serial data to operate the shifter's position and gages. Those signals are class-2 a signal from 0-7 volts and a good volt-ohm-meter on pin two of the OBD-2 connector (Cavity 2 - 1.5mm wide) will show 3.5 volts on average on an active circuit. By disconnecting the battery does nothing. Saved favorite radio satiations are still saved on an electronic erasable programmable read-only-memory or (EEPROM) as these are used in almost every module. Re-connecting the battery most likely fixed a dirty-corroded cable and have system voltage, 13.2 volts hot to 14.6 volts hot. By disconnecting the battery (If it will run) you lost the opportunity to check and diagnose the root cause by seeing 12.6 volts at the alternator B+ & ground, then 12.7 volts the battery bolts on the side. If you had a (DVOM) with a Min-Max feature, set it to voltage, crank over, go back to the (DVOM) and see 9.8 volts. This maybe enough to start it be freaks out the electronics or produces 10.4 volts to the entire system while running. Even the shift display has an electric switch on the side, by hydraulic switch inside on the valve body of the 4L60e. Alternators produce direct current, get hot and change output depending on temperature. The lower the temp, the higher the charge. But is one of the 3 positive diodes or 3 negative diodes fail and leak voltage backwards, then A/C voltage goes out thru the entire DC system. This activity disrupted the 0-7 volt class-2 serial data signal, UART, Keyword 2000, Keyword 2001 or GM-LAN (Two wires, twisted 9 times per foot, 120 ohm termination resistors at end modules. 1 volt high & 1 volt low to offset high voltage induction and frequently foil covered and connected to ground.

Thanks bro, your knowledge actually works even on 800 cc alto car, I was badly disturbed by car abnormal rpm, I paid more than 3000 at service center they cant setups properly , done throttle servicing too, I request them to do calibration too, but they denied, it's ok.. veh is ok..they said, but I was not satisfied by them... finally I did by ur help, thank once again..🙏

I was sceptical at first but it worked like a charm did this on a 2006 Buick Lucerne and upon reconnecting the battery the interior lights came on the horn honked and stopped it started like a charm.
This helped me save a ton of money. I had a ECM malfunction and the recommendation was to reset the ECM but the dealer wanted to charge a fortune just to do that. Worked like a charm. Thank you very much 🙏
I came here looking to see if this would work for that exact reason! Thank you
Good advice
Were you getting any activity from the vehicle before you did the reset? I crossed the leads on a jump start and I have no lights or anything. Will this work on fried ECM?
@@stevencamacho8234out
Could I do this as a overnight process
I just used this method on my 2005 Honda CR-V it worked like magic. I tried a Milwaukee impact, a Dewalt impact, my air impact, a long cheater on a breaker bar using the Honda tool (I broke the harmonic balancer doing this). First try using this method it came loose. Hooray!😅 Thank You.🎉
This is an absolutely reliable procedure that calls ecu flashing I communly uses on Audis and chevy very successful procedure because it is able to drain mili-volts in every single circuit like capacitors resistance and chips even E-prom component thanks .very nice video greetings from Venezuela.
After more than a year of my engine light being on with the knock sensor code, which was preventing me from getting it inspected for 6 months, I just did this today on my 2002 Chevy Silverado 1500 HD and with this method I was able to get it to pass inspection. I got the knock sensors replaced more than a year ago but that didn't stop the light from coming on. Hopefully, with the new sensors and the ECU recalibrated using your method today, it is fixed now for good.
Did that work
I'm curious as well. Did it work? I have an 02 Silverado 4wd
@@waltercallihan my solution was finding sensors from dealer that aren't faulty. You need to test them before installation even the ones from dealer. There's a RUclips video that shows how to test them. No light for about 2 weeks now
You can buy a cheap OBD2 scan tool that will tell you the codes and you can clear them. Harbor freight even sells them....
Knock on wood -- been chasing this for two weeks now! Did the above ECU reset -- couldn't trip the codes (heavy rainstorm preventing monitor-resets) but also couldn't trip the KS codes. Will be retesting in better weather tomorrow. Optimistic... but have been that way a dozen times now! Will update if this nailed it!!
Man, divine intervention directed me to you. This is EXACTLY what Ford says is wrong with my Explorer, and they quoted me 1800.00 to replace it. I'm excited to try this! THANK YOU
Any luck?
@@brettzel91 unfortunately, no. I went just now and picked one up, and now I need to know how to program it to my truck. Any "how to" information you can share? I suppose I could have done something wrong, but it was pretty easy to follow, so I have to assume now that the ECM is actually defective.
My 2006 Ford focus PATS systems activated and would not turn over. I did this and it reset the system and started right up. Saved me from having to have a locksmith reprogram my system.
R u serious? My 2010 f150 went into Pat's lock 18 months ago and it sat in my backyard for 17 months I was fidlling around with some wiring under the dash and alligator clips and somehow magically got it too start drove it for a month perfect no problems at all then it goes back into security lockout mode once again and now I cannot get it going I'm going to try this in just a second and I'll let you know if it works I'm really optimistic after your comment fingers crossed
Thank you . Thank you. Thank you. 2006 Silverado 2500hd battery change, then truck lost it’s mind. Followed this procedure, works better than ever!
What do you mean lost it’s mind
😅😂
This does work folks,Ive done it many times.
Wil it work on 2010 altima
@@marklewis4664Yeah. What this does is it temporarily kills a little battery in the computer that retains memory. Then the computer can relearn the sensors.
Thanks so much, I had the Rear AC Blower running all the time and it would not switch off (Toyota Sequoia 2014), by doing the reset steps in the this video the problem is solved.... 🤩🤩🤩.
Always check if you can do this with your year/make/model. This has been a common thing to clear the KeepAlive memory, except for '96 Fords. '96 was their first year of OBDII. Doing this on that year, maybe '97 and '98 as I can't remember when they implemented the fix, will instantly fry the KeepAlive circuit thus needing an ECU replacement. They fixed the issue eventually in later years. As always, proceed at your own risk.
Interesting video. I just disconnect the negative terminal from the battery and then turn on the lights to clear out residual power.
Thanks for clearing that up 👍
@@martyhughes7591 lpqqpppqa😊😊😊
Okay I was driving with a bad camshaft position sensor and the signal was so weak that the ECU turn off the fuel and spark. But once I replace the camshaft position sensor the fuel and spark is still off and my car still won't start. I did this and still won't start. You can't turn the fuel and spark back on once it has been turned off. I'm just going to have to replace the spark plugs again and I'm gonna have to replace the fuel pump. Bad camshaft sensor really messed up my car. Now that I have the new camshaft sensor my car still won't start.
@@BryanG830You might have got a bad sensor. I'd take it back and have it replaced. Before I put a new fuel pump in it. Because fuel and spark are both controlled by the computer. Sounds like the computer still isn't getting signal from the cam shaft sensor. And getting bad electronic parts happens all the time. Just a suggestion because I had the same issue with a Toyota Corolla. Replaced the cam sensor a second time and fixed it.
@@BryanG830 Try replacing your MAF sensor with a known good one.
I followed your instructions and got my car inspected 😅 thanks alot
Have a 2003 Trailblazer EXT Northface Edition 195000 miles, 4.2L 4WD. Had an issue come up where I was losing MPG and power, wouldn't stay on cruise control. Took it to a mechanic in another town because it broke down on the highway, spent $80 for a sensor, no joy. Replaced battery, spark plugs, fuel filter, air filter, and had oil changed; still no joy. Towed it to my long time mechanic ($180 for 40 miles), learned catalytic converter was full. Had it replaced. Still not right. Seafoamed it in gas tank and cleaned throttle body, still engine stuttering and bad mileage. Watched this video, replaced plugs with Bosch plugs and followed directions to clear ECU memory. Took it out and drove it, 45MPH on cruise without any stuttering; 70 MPH, no stuttering; 55 MPH no stuttering and fuel economy is back to normal. Problem seems to be gone! If it is, saved me buying another ECU and having it programmed, probably $800 or more. Thank you!!!!
Very cool. Congrats! And what a headache!
I took my car in garage after ignition switch and starter. I bought the reconditioned and programmed ECM from Flagstaff -- a company from New York ( priced at $176, but with exchange and shipping = $384)!!!
I'm a dyi'er beyond my skill set.
I took it to my mechanic who had a scanner, diagnostic technical knowhow, etc.
David W.- just sent my ECM back to Flagship One for reprogramming. How did they work out for you. Seemed like the BCM issues never reset. Your thoughts please....

So far so good
HEY MAN WHATS UP. I APPRECIATE THE INFO HOMIE. I DIDNT KNOW TO DRAIN THE MAIN VEIN OF POWER TO RESET THE WHOLE SMACKAROO. GOOD ONE CHIVATO
Thank you very much young man if it wasn't for your video I wouldn't know what to do when my car wouldn't start, much appreciated.
Did this fix your no start issue?
@@vasilybk1760 only if you fix that actual issue at hand. Meaning whatever was causing the no start originally.
On a modern car this could possible cause power spike in the capacitor causing more issue or even new issues including a fried ecu. You should always use a resistor inline between the negative and positive cables. 1ohm 10w resistor should take roughly 15min . You can use higher resistor but Higher resistors wil need to be connected longer
My Mazda 5 2010 diesel have suddenly lost the Bluetooth - option does mot appeare when pushing on the phone knob. - mute - appeares instead
Anyone know procedure for resetting?
where do you pick one of them up at?
Usualy when i push the phone-button the i car phone system starts asking if wsnt to make a call, reg a New phone, etc - and when someone calls me while i my car i hear 'incomming call' i push the button and anser the call over the loadsystem..
My obd2 also get No contact with the car.
After disconnecting the battery, turn on the headlight to dissipate the capacitors.

Work for my 1996 chev Tahoe ty I was fixing to buy new ecm man nice job
Hi could you tell me what problems you had before resetting? Thanks
Thanks so much for sharing this method. I will perform thess same steps after replacing my throttle body.
Did it work, I cleaned my throttle body and now my Chevy idle is to high after I step on the gas ,
@@michaelgallo2723 on my ram when replacing mass air flow the manufacturer said to cycle throttle 5 times to the floor with ignition in Acc mode
@@michaelgallo2723 ppl never put their end results for us all to share. Sad, but true. Hope you fixed your issue.
as you said that more complicated cars you cannot dissconnect the battery, my question is don't they always dissconnet the battery on every vehicle when they weld the car to protect the battery, I am no pro at this but I am wondering how this works.
Ssangyong Rexton 290 2002 automatic, would not shift to 4th gear and would usually shift very ruffly otherwise.
After doing the reset, as shown in the video, shifting to 4th is no longer an issue. Also it shifts like a dream between all the gears now.
Thank you very much good Sir!
This really works. But, it is only meant to reset the ECU only after the problem has been rectified.
This was a big help for my 07 Expedition. TCM was acting up and a reset did the trick. Thank you for the video!
Thanks!! Worked perfectly with a 2014 KIA Sorento!
I've done this before and I think it really works,I have a 2001 vw Jetta by the way 👍👍
you are not sure if it works ??
I have no check engine lights but can’t smog because of modules not being cleared. Will this clear them? 08 wrangler JK manual transmission
Thanks so mucho for greate information...i fixed a Ford escape 2012 with this process.

Hello what were the problems in the first place before you reset?
@@philjagdon6774 I am not sure what trigger the immo. I recall jacking the front of the car, quite high, for some maintenance, maybe disconnecting the battery, and afterwards the car did not start.

Where is the ECU located on my
66 Chevelle Super Sport ?
It won't stop pulling both front tires off the ground ,
And gas mileage is 3 miles per gallon ,but horse power is 450 ,
Should I go back to the Crane
camshaft and 1050cfm carb. ?
If you want to go a step further, with both battery terminals DISCONNECTED, turn the key on and then off once.
What does that step do for you?
That's a good 1, open the circuits. Like a 2 way switch.
You mean turn it on then disconnect the battery and turn off the key ? Thanks
@@philjagdon6774 Read it again.
Awesome video 🙏🏽
I’ve ordered a remanufactured BMC flashed to my vin twice, and both times got a no start. I’ll probably have to perform this process to get it going, but now I’m wondering what will happen if I reset my original BCM 🤔
I’ve had my truck for 2 years and the horn never worked, and the same with the A/C. Recently the third brake light stopped working
Since last summer my CEL would flash after about 3K rpms, it started idling rough, and had all types of codes.
Replaced everything, cleaned all grounds, and now I’m down to the BCM, but I’m really wondering if this step will cure it of the random codes, cel flashing and everything else.
THANKS!!!
Do you mean connecting the positive and negative battery cables together? And you are using the jumper cables to hold them together? Someone told me to do that so i can reset my navigation on my 2007 honda odyssey . im just wondering if this is what they meant for me to do
Yes
Hoping this will work for my 2002 Dodge Ram. Need a good battery first though. Had it running earlier but not enough juice within the battery to keep it going with my foot on the gas.
How do this work for my 04 Chevy duramax? Obviously she has 2 batteries
Why did you remove/ isolate the positive from the battery in this video but left the positive connected to the battery in the other video with the Ford Explorer?? Is it different with the Chevy or does it matter?
Absolute life saver.
If this actually works on my 2013 accord then YT should add another donation feature on ur channel cuz it’s saving me almost $2000 to reset or reprogram my dashboard lights (steering wheel, traction and tire pressure) after I changed my clock spring on steering wheel last week 👍⭐️💰🔧🚘😅
Special exfil exit glitch works if you do it during the countdown too. We do it daily cause we initially were under the impression we have to close the game before the countdown ran out. 😂
Idk if its gonna fix what i got going on but its a free education and well worth a try … so that means it gets a like and a comment .. lol
Will this work to relearn my crankshaft position sensor after I replace it?
no.
I have an 89 Dodge ram van 318 didn't really need to tune up but I did anyway in the 6 years time that I've known it it's never needed any work plugs wires cap rotor air filter immediately ran like shit. Check coil it was fine so replace fuel filter just recently found out that it may have the brain box. I've heard of disconnecting the cable watch the video and liked it my question is the tipm the same as the ECU is that the same as brain box? And what's the difference between a hard reset and a soft reset? Again the van is always drove by and it was our church van always had a tank of gas right now I run on here a lot and even ran out a couple times should I check the new fuel filter it's only been 2 weeks should I drop the gas tank and clean it? Not sure where to start and I know nothing about computers thank you
I hope this works on a 2010 Malibu! Thank you.
absolutely phenomenal video. Works like a charm on my 2004 tahoe
What problem were you having?
@jacksmall8968 what was your problem mine just lost power while driving and now no start no crank
@@kennethlsealsjr4874 same. I wish ppl would give feedback of their results, would be helpful for us all!

Wht are u conneting the cable to? I cnt tell are u connecting it to the negativel cable?
Thank you for your video. Unfortunately by truck didn’t start.
Does this affect Recalibration done on the ECU?
Almost all the calibrations in the Engine Control Module are written to the EEPROM meaning it has to be electronically erased. This is done with a scan tool.
Clean the battery terminals with a small wire brush, a mix or paste of baking soda & water and use an old tooth brush. It is a chemical reaction between an acid and alkaline. Even a cola has citric acid so it can works on Cooper oxide, the part the turns green. Have the battery tested at you parts store. If you have / buy a digital volt ohm meter, then when running check the voltage level at the alt and move ground around to the fender, frame, block and battery negative. You are looking for a loss. Loss means a dirty, loose or corroded connection or broken. Remember that alternators produce the negative current off the back housing. 99% of the times, there is a threaded shallow hole on the back that allows a 10 gage or larger 6 gage wire & eyelets the from the alternator to the block, cylinder head or intake lowering resistance to the battery. Using "Star Washers" sold at home improvement stores sell internal & internal star washer that are effective on rusty, galvanized, painted or undercoating. But checking for voltage drop is alway done with engine on, lights, heater on high, wipers, stereo, just current flowing thru an active circuit to check. It works every time.
An Engine Control Modular's had to sent out for basic reprogramming be it used or update to a restoration. Visit LT1Swap website because Brendan has a lot of offer as extremely reasonable prices. DK, Omaha.

Exception would be jeeps 2018 and above have 2 batteries main and Aux and is you do that you will blow a fuse
Going to try this on a V6 Camaro I'm working on.
Thanks good video. I was told to start the truck put the transmission in low or 1st gear for 3 minutes and 2nd then drive and reverse. Does it make a difference ?
Yeah. There’s a ridiculous number of relearn processes out there. Some work. Some don’t. It is highly dependent on the year and if it has an electronic throttle body or cable.
I hope this works on my 97 Cherokee rough country. Need to get her runnin soon
What if I have beat in my vehicle should I disconnect my system from the rest of the electrical to prevent shortage or will I be ok I have amps and a capacitor in 99 durango
This is a nice tip, however I have a problem with my car. The dash board has no power as well all the body control function are not working but there's a power going to fuse box under the dash board from the key switch. Can you help me what is my next step?
My 1999 456M GTA Ferrari has several separate ECUs. Will your method of resetting them work on my car or is the engine management system too complicated?
Sir, my car has already started manufacturing,1,2,3 ignition coil is working fine, but ignition coil 4 is not supplying current, will the help of your teaching,solve my car problem.
Can u use regular black and red jumper cables to do this???
You can simply apply the brake pedal and accomplish the same voltage drain

After replacing the fuel pump in my Jeep grand cherokee laredo 3.7 WK- Im now having a problem with a vapor lock and my new pump is making a ringing/humming noise off and on-is there a way to fix it with a inline check valve or inline filter of some sort. I have to release pressure on the fuel rail to re-crank it after it runs for more than 20 minutes/ which is a possible fire risk.
My car is running rich what do I need know what I need to do. Also something is draining my battery
Will you answer ASAP God bless you and your thank you so much.
what type of jumper cables are u using? i aint ever seen cables with just 2 ends
Right???🤣🤣🤣
Will this wake up my 4wd tccm?
Would It be safe for me to do and get the stock/original tune back if the previous owner of my truck (2003 Sierra 1500 5.3l) took it to a shop and paid to have a custom "gas saver" tune put on it? and if so it would just revert my truck's tune back to stock right?
Because that's the goal here since the tune on it now doesnt allow it to rev past 3k rpm in any gear when on a stock tune 1st and 2nd gear shift out at 52-5600rpm.. so the truck just feels gutless and I to revert back
Can we direct disconnect negative sensor terminal for other task ? May it damage or create problems in ecm?
Thank you so so much! I put my car back to the road
Is this idea effective for Hyundai accent 2017 model. Gasoline?
