How To Reset All ECU No Scanner No Tools Required

You sir are a king 😭👑 you saved my car and money the immobilizer on my car was not allowing the car to start the mechanic wanted to change all my immobilizer, ecm, key fob and quoted me more than what my car's worth after trying this it magically started thank you thank you thank i have no words to express my gratitude sir 🙏🙏😭😭❤️

It works for me. Thank you so much. After putting everything back.I drove it for a minute and all warning signs are gone.

Keyless entry receiver stopped working on Tahoe and my hair was beginning to fall out until I did what you said and it solved problem. Tahoe was going into sleep mode and stopped listening for remote signal. Thankyou, sooo much unfortunately, hair still falling out for other reasons. Great video!.

Didn't see the dash lights BEFORE this procedure was done. Surely this would have been a good idea to show us a successful outcome.

It worked well. The radio and while making a Bluetooth call, they both would shut off for a few seconds and then come back on over and over, and I would lose power steering sometimes too. The check engine light came on and that's when I had Auto Zone give me a diagnostic trouble code, and it was showing the power train system, and ABS. Sure enough though, and the attendant tried to sell me a power train system for $456.90, but she made the mistake of saying that the codes just needed to be reset and that when I found this, and two other videos telling me to do this. Thank you very much!

Thank you for posting! This saved me a trip to the dealer to clear a fault code. Best description of this process I’ve seen on here. I recently changed out the coil packs and plugs on my e92 335i. I tried to reset the “service engine soon” light using several scanners but none of them could clear it or even see the fault code (presumably because it is now fixed). This fixed my only remaining problem, no more “service engine soon” light now. Only thing I might add is when hooking things back up to hook the positive up first. I’ve heard these cars are sensitive to that and it might cause a lot of other issues if the negative is hooked up first.

Thank you so so much! You saved my sanity! Couldn't figure out how to make my car run once again, and this trick worked. Thank you!

Excellent advice I also turn on the head lamps while the battery terminals are off, it drains all energy and you get a full factory reset, excellent video!

I was involved in an electronics sector for 10yrs or so. And I learned that DC Grounds are in pivotal position in circuitry and I developed a habit that I always disconnect a positive side before a negative side so that there would be no floating voltages around components which might kill components on PC boards. Just words from my experience.

I agree hundred percent? Negative first then positive? And connect positive first then negative

Are you from LIBERIA 🇱🇷? You speak very very clearly Sir.

God bless you! After disconnecting the battery I had a lot of electrical errors. The mechanics were telling me that I had to replace the components. Whit your advise I managed to delete all of them and I checked with vcds on the Passat B6 and they are disappeared. Thank you a lot !

Yes, that's right. When I upgraded LED light bulbs it might mess up the ECU as my dass board light sometimes come on and off, also the ignition. By chance I disconnect the battery and leaves it for about 10 minutes then reconnect it. I replaced all the light bulbs back from original. Wow, everything working as it used to be. The only thing in the video, I'd like to mention that : When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative. Many thanks for your video.

My k&n filTer felt off the pipe and my 18 taco threw an engine check code. I followed your instructions and it worked perfectly.Thank you!!!!

Remove negative cable first, connect last for safety. Rest is all good, nice video. Good luck

Thank you SO MUCH my car would not start after running into some water-But now it starts and runs

We followed your instructions exactly and our 2017 Subaru outback reset perfectly. Thank you so much for your time on doing this video. We sure appreciate it!

I like Scottie Kilmer method of putting a resistor in the jumper cables chain to prevent any sparking from a sudden discharge.

The ECU packed in on my 1.7tdci zafira .Total nightmare .Got all parts from a donor car .Clocks .ignition and transponder .fuse boxes .Was a waste of time .Rear fuse box in energy model is different from my elite model .The ECU on it's own from the donor car never worked .has to be blank and reset .Finally got there with an ECU from ECUs to go in Redcar .Great result .Fixed now thank god .

Thanks from Yukon, Canada, for doing this and your time budd...
