Most people are misinformed about this.... just disconnecting the battery doesn't reset anything, it hasn't really since the late 80's. The correct way to do it is to disconnect both sides of the battery (remove it completely from the circuit) and then hook the two positive and negative cables together with a jumper cable or something similar.... this completes the circuit so the PCM's capacitors can discharge, then turn the key to the on position for approx 10 minutes. This will discharge any capacitors in the circuit which may facilitate the retention of memory by powering the ROM and the RAM modules. Without connecting the cables to each other AND turning the key on, the caps on the printed circuit boards cannot discharge because there are two opens in their circuit (the disconnected battery cables, and the off ignition switch). I don't know where the myth that you can just disconnect the battery came from but that hasn't been true for nearly 40 years. The circuit must be completed and the caps discharged.... that's how it is done. I'm really surprised that info isn't readily available on the internet, must be a trade secret they don't want laymen to know.... job security ya know.
For my actual job, I have replaced several capacitors in my day and know all about discharging them. I tried that before shooting this video and even fully discharging everything did not reset the computer fully.
@@zachattackcustoms Greetings: True. That is Bcuz it is a ROM / EPROM device. The caps discharge dumping the RAM and temporary systems. However the programs, faults, commands, history and related is in the above noted ROM and EPROM devices. Such R not effected by cap discharge or OV. Therefore the previous statement, of which U replied, is mostly false. Thx 4 the share. Bsafe
May not have totally reset the system but by disconnecting the negative cable for 30 minutes cleared my PCS system error. This allowed my adaptive cruise and lane keep start working again. Also saved me a couple of hundred dollars that the dealership wanted to charge.
I watched this 8 minute video to find out the way to “reset a Chevy Silverado computer” per the title of the video, is to take it to a local shop and have them do it. I felt like 7.5 minutes of the video was you trying to sell a diagnostic tool. You should probably change the title.
These guys are mechanics that are just here ti bring business to to shops that are extremely expensive and very rude assholes and the woman that work there are worst
Thanks for the feedback, I have adjusted the title so no one will find the video and just allow people to keep resetting the battery only to find that it doesn't work. I will also work on the description. Sorry you found it to be misleading, I just title things based on people's searches to help them find out that there isn't a way unless you take it in for a full reset. I showed off the scanner because it helped in my discovery. I do apologize.
That was the main point I was trying to get across in the video. In my experience, resetting the battery may reset some things, but it does not reset everything like most people say.
To reset to factory default use a 1ohm 10 watt resistor remove both battery terminals and connect the resistor between the two terminals for ten to fifteen minutes and now you are set to default.
I just replaced my motor and had everything taken apart, now that I got my new motor in my idle is all messed up so I have done the throttle body re learn process a few time and seemed to work.. untill it didn’t. It still idles a little high and now if I shift from Drive or reverse to neutral sometimes the RPM’s jump up to 2500-3000rpm and won’t drop back down unless I shut to truck off.. would a ECM re flash be needed to reset this issue??
I did a motor swap years ago and never experienced this issue. Honestly I feel like it depends on the year. The newer the vehicle the more it depends on the computers and what data they are receiving. Did you clean the throttle body and the MAF sensor? If not I would try that and then do a reset on the computer. Don’t take it to a dealer, they will charge an arm and a leg.
@@zachattackcustomsI did clean the throttle body out pretty good yeah, not realizing it would matter I had the throttle blade open to clean all the junk outta the housing and off the blade, I didn’t touch the MAF sensor though. I did try the throttle re learn process a couple times and I thought it worked until I let it idle for few mins and then once I tapped the gas pedal the rpm’s rocketed to 2500-3000 and never dropped.. it’s done it a few times since too
Hello friend, is this scanner used to code a new ECU? I have a problem with my Silverado, I live in Brazil and there is no one here who can code the new ECU
No, the only way to code the computers in the newer Silverados is to pay to get them unlocked unfortunately. That’s why it cost so much to tune the newer trucks.
So don't believe these guys, but buy this scanner. Thanks BTW for the truck info in video like what issues you were having that scanner cured , so on so forth. Best non info info on U tube
That’s the thing, I was preparing to film a video to show the scanner off, I wasn’t having any issues but the scanner found a communication error. The auto/stop start stopped working before and I didn’t really care to get it back but after the shop did a reset on the computer the auto/stop start started working again. This video just reflects my experience with the scanner and I have disconnected my battery several times for different mods and obviously it didn’t reset the computer.
Thanks, definitely been trying to learn all the technical terms on the scanners, there is a lot to learn. Biggest thing I’ve been interested in is the fuel trims. Not a certified mechanic by any means.
You can’t even buy a decent repair manual anymore. They are useless now. You’d have to buy the Master Mechanics Books to get any real data on your vehicle now. They cost over $3k each 😕
Yep, I hear ya. I used to buy the Haynes manuals at the auto parts store to work on my older vehicles. It's painful now just to try and find torque specs on anything these days. It's mainly just google search and hope the people on the threads are correct.
@@kdtxtooldad Don’t care if you buy this scan tool or any other scan tool, point of the video was to inform people my experience on listening to all other videos telling you that resetting the battery fixes everything. Because it does not. Title is how to reset the computer, did I not answer that question? You have to have a scanner tool more advanced to reset everything. Computers these days are locked down and you can’t even tune them without unlocking the ECM. I would say it’s a perfect video that doesn’t give you false hopes. It tells you about a truthful experience. lol the thought that I care about making a commission off of a $20 scan tool is hilarious. Might make a dollar if that. I am here to help people not make a living on TH-cam. I have an actual job that contributes to society unlike most TH-camrs.
@@zachattackcustomsGreetings: The Information was OK. Perhaps rephrase the title 2 reduce confusion. I was not confused or misled. Nor was I hunting info as have others. I am here 2 observe, advise or critique. Bsafe.
I watched and didn't learn anything new. Your title needs to be changed. I wasted over 8 minutes to find nothing. Could have used that time on a real how to video. 😊
The point of the video is to help you understand that there is no video out there on how to actually reset it the computer for newer vehicles. When I went looking for one to help me diagnose some problems, none of the older videos helped. I feel like the manufacturers are making it so hard these days to work on your own vehicles.
You can always buy a scanner and do it yourself, you must have missed the point of the video. The point of the story is all these people that say to just disconnect the battery are wrong.
I am sorry it seems that way to you. I honestly just try to help with my experience. I am confused on how my title is click bait. I stated what everyone else tells you to reset the battery and I said that it is false due to my experience. Sorry you feel that way.
The point of the video is that you can’t reset the ECM yourself by disconnecting the battery, sadly I have to title things by analytics on what people search or no one would ever find the video. The point of the title is for you to see what you are searching for and then get the facts. I only try to help people on this channel, not deceive them.

Is there a list describing the initials stand for?
I did the brakes on my 2022 Denali. Unhooking the battery completely did not reset anything for my.

To reset to factory default use a 1ohm 10 watt resistor remove both battery terminals and connect the resistor between the two terminals for ten to fifteen minutes and now you are set to default.
That would pretty much be the same as shorting them together
Will it work for permanent codes ?

You have to disconnect the battery and put a jumper across the battery cables to drain the capacitors. Da.
Yes I have drained the positive to ground before, no luck.
Still doesn't work
