Good info for older vehicles pre 2003 ish , but be aware. You may accomplish the task of clearing stored codes, however a lot of that information would be helpful to diagnose current issues so your not testing or changing multiple components. Many vehicles store data to set thresholds for components to rely on. If you hard clear your stored data it may take days for your car to set new parameters. With a professional scan tool you can remove unnecessary or multiple issues and save needed data. If necessary I would only remove neg bat terminal with a terminal tool and turn on some lights to drain down stored power in capacitors. If you hard drain the electrical system on some new vehicles you lose data stored for fuel economy and performance curves. Radio, GPS, phone, seat, some keyless entry, and many personal settings on some equipped cars.

Hay Scotty, In resetting the PDCM with a resistor, I noticed that you disconnected the positive terminal from the battery first.Yosu even used vice grips to do so.I think that you were putting yourself at risk for creating what could have been a dangerous spark around the battery with explosive gases!! If you had touched any of the negative ground surfaces under the hood this could've happened. I enjoy watching your informative videos and want to keep you SAFE! I feel that you should explain in a video why when working around a battery that you always disconnect the negative cable first on a negative ground vehicle, then the opposite when reconnecting. It would also be a good idea to instruct people to wear safety goggles around batteries, as you only get one set of eyes!! Keep your videos coming, STAY SAFE!

You are so correct on that resistor. Even though you may remove the ECM, there still is voltage potential in its capacitors. I am a retired electrician so I used to work with things similar to this.I can see if a person shorts the --- and +++ together, that would cause a large inrush of current through all of the electronics from the negative to the positive destroying its solid state components. Just a very slow bleed of electrons going from negative to positive wont hurt any of the surface mount components. Scotty Sir,,,,YOU are the man. I find your podcasts very informative but entertaining as well. BTW, were you an Army paratrooper at one time?

[@badbrain3185]

I'd use a 1k ohm resistor. It would be a lot slower to drain any charges, but at 1 ohm if there are any charges built up that might drain them way too fast.v=iR or i=v/R.

[@electrician248]

@@bettepage4856 It all depends on the manufactures design.

[@rutchu]

Around the 4 minute mark, when taking off the batter terminals, you should take the negative off first. The neg is grounded through the frame, and if you attack the positive first and are vigorously twisting with pliers, you might accidentally touch some other metal part electrically connected to the frame and complete the circuit with little internal resistance, resulting in a nice, burning arc. Watches, bracelets and rings are especially dangerous in this case.

[@LarryCook1960]

@@CreeCarnivore Electrically speaking, it doesn't matter. The reason for removing the negative first is if you should accidentally touch the wrench to ground while it's on the positive terminal, if the negative is still attached. That would be bad. If the negative is removed first, you don't need to be careful when disconnecting the positive.

[@rtel123]

love your videos but agree with "Vetsus". If the wrench on the positive touches any engine or body metal, you get electric welding and could blow up the battery with the short circuit to ground.. If you remove the negative (ground) first and hit something with the wrench, nothing happens. Once it is off, the positive is no longer chassis-seeking, so you will never short the battery that way.

[@capnbly]

Good practice to always remove the negative cable first, since it is grounded to the frame and body.

This is a very handy tip! I take precautions such as this when I work on computers, but it never dawned on me to do the same when working on car systems. It makes me wonder why car manufacturers don't just include a factory reset button as part of the wiring. I'm guessing they don't include a reset because that would make it too easy. And regarding scanners, I did take Scotty's recommendation from a previous video and purchased a ThinkOBD 100 scan tool. The $35 scanner saved us hundreds when we knew roughly what was wrong and found a mechanic who used their $5,000 scanner just to verify and charged us nothing for diagnosis and knew exactly which ignition coil to replace.

[@robertbritton9674]

His scanner cost $5k. The snap-on scanner that a lot of shops use are $10k.

If you're concerned about a direct short causing a spark and damaging your electronics (I'm not too worried, but whatever), and since most folks don't have a 1 ohm resistor laying around (I do, but I'm weird) just find any incandescent light bulb, from a car or a home, and include it in the circuit. They have a low resistance of a few ohms when initially turned on. Or just use an old fashioned automotive test lamp, which use an incandescent bulb.

[@liz6034]

Would love to know how!

[@ScotTheGr8]

Might want to use a 1,000 Ohm vice 1 Ohm resister. 1 Ohm still gives lot of current when you short the plus and minus sides together. If you do, resister can also be smaller than 10 Watt.

[@edmercer1459]

I just posted this to Scotty.. ScotThe Gr8, YOU are correct. Hey Scotty, at the start of the video time index 3:35 you said the resistor is a 10 WATT 1 (one) OHM resistor. Near the end time index 9:30 you show the resistor and it is a 10 WATT 1K ohm. 1K = 1000 OHMS. please let us know which one it is! It most likely what the part shows. 10 watt 1000 ohm. THANKS!

[@alext8828]

@@edmercer1459 I noticed this the first time I saw this. Does he know what the K means? Not sure. Might be an oversight. I would go with the 1K. I don't even know if they make a 1-ohm resistor? ChatGPT says they do. Go with the 1K. How do we know when the process is finished? Shouldn't we include an ammeter? Did you do this yet?

[@johnsupervita5409]

Hey Scotty your awesome buddy but I have to point out I always instruct my Airman to always disconnect the negative terminal first. This avoids them from taking a welding class. 👍

[@dnkjdnkj2679]

This depends if you have a negative or positive earth electrical system> Either way, disconnect the earth cable first.

[@DMetal13]

Thank you for everything. Spent thousands over the years in repairs until I decided to use youtube university for the majority of maintenance now. Just got myself a bluetooth scanner for my 07 Ridgeline after I took it to the dealer to check out some overheating problem. They wanted over $800 to replace a bad ECT sensor that after looking it up myself, took me 10 minutes to replace and the part was under $20. Completely mad about how many people get ripped off like I almost did. Will forever watch your videos.

[@buggsy5]

That is just one of the reasons why auto dealerships are so distrusted. A few are honest, but your odds are better by using an independent repair shop instead - although many of them are crooked as well. Or have untrained mechanics that shotgun any problem - with you paying for all the parts/time for their failed efforts.

[@davidstark8894]

Like some of the others say in the comments, I think it is a 1K ohm or a 1.3K ohm resistor. Just want people to use the right part.

[@wingerrrrrrrrr]

It was oddly specific to even say 1 ohm 10W, since pretty much anything could be used, old turn signal bulb, headlight, car vac, load tester etc.

[@kmac1959]

@@wingerrrrrrrrr, is that true? That I could just substitute the resistor with an old turn signal bulb, jumped between the disconnected positive and negative battery cables?

Hi Scotty! Just want to say THANK YOU for all the help you've given so many of us! Literally couldn't have done it without you!! My question: I just had a used TIPM installed on my kids Jeep Compass. Everything works as it should except for the heated seats. The shop tells me that the heated seat portion of the TIPM needs to be reconfigured to this car by the dealer for almost $200.00! Will this "RESET" take care of the problem?

[@Eric_W]

If only you were the standard for all mechanics, Scotty! I have ZERO trust in mechanics because most of them have no respect or morals and some don't even have a conscience! Honest mechanics get repeat customers, ripoff mechanics lie and/or screw up your stuff to try and get you back as a customer. If accountability was extreme enough so that mechanics were afraid to rip you off maybe mechanics would be trusted by people... but yeah I know, that's a laugh! Thank you for your honesty Scotty!!

[@d.vaughn8990]

I was a car dealership mechanic - ASE Master mechanic with L1 Certification.. I always tried to do the customer right. Problem is, mechanics don't get paid to "do it right". Mechanics only make money if "they" cut every corner in the book. The dealership fat cat's (management) make all of the money. The mechanic can't even afford the car he is working on, or his tool bill, on the Snap-On truck! Yes, good advice...go to a reputable local independent shop.

[@canteskuyapete1459]

@@d.vaughn8990 I'm thankful you said this. I bought a newly used car, and the car salesman was able to get me a really nice deal on it. I've shopped around for other cars in my area, and 0 of them made the cut. Most were easily a minimum of $3,000 over. I went to get my transmission fluid flushed, as it was due time for it. At the dealership it would have cost me easily $430.0+. However, I went to another shop and it it cost under $200 with tax. I told them if they had a warranty on it, if it goes bad or wasn't properly done that it would be fixed by them, and that price was already included under their liability! I go to a different mom and pop shop here in town to always get a 2nd diagnosis on it, they have never started me wrong yet. Even if it happens, I can look passed it because they are the ones that actually care and will take their time and work after hours even if they are closed for the day. I love it, because they won't "stop" fixing on a car just because that time hits 6pm. They started on the car and love to finish it and thoroughly look after it from start to finish. Not all busted local mechanic shops have your best interest, but look for the ones that do!

[@georgemoomaw9437]

After a decade on KZbin I just ran across Scotty Kilmer yesterday. I don't know where he has been hiding, but damn - what great videos. If the resistor here ever drops below ninety-seven-cents, I will buy one. Or maybe bite the bullet and buy one sooner if I ever need to reset my computer. Great advice. (Entertaining too)

[@g5alive795]

Scotty, I know you know this, but many may not. Always disconnect the negative side of the battery first. I learned this years ago. 😲😲😲

[@samkitty5894]

True...

[@imrileth6618]

Its a good guideline but it doesn't matter unless you manage to short circuit the tool against metal part (I have done that with tractor haha) It's not even possible in some cars to do it that way. In my car the positive needs to be removed before the fuse box and battery cover and holding screw can be removed then you can slide the battery forward and access the negative terminal because the battery sits length wise in the engine bay with the negative side under the windshield and positive side towards the front of the car so only it is reachable without removing stuff and moving the battery forward.

[@samkitty5894]

@@imrileth6618 If you start removing the positive terminal 1st and touch nearby ground, there will be sparks flying... Now, if you remove negative terminal first and touch nearby ground, nothing will happen. Then, with negative terminal removed, when you start removing the positive, and touch nearby ground, there will be no sparks since negative terminal is disconnected from the battery. I always remove negative terminal 1st. I still have all my fingers and all my tools...

[@daleinaz1]

Yes, the ECU has to relearn the idle pattern of the car. Some cars have a procedure to "teach" the ECU in the owner's manual or shop manual. I had to do that on my Dakota after cleaning the battery terminals, before getting the annual emission test.

Based on this information, you could damage your computer if the positive cable contacts any bare metal that is grounded to the frame. Also, I wish you would have disconnected the NEG. Cable before the Positive Cable.

That`s what we like about our 1970 C10 P/U. When you get the dwell right it purrs like a kitten at idle but once throttle is opened it roars like a lion without any computers or complicated electronics. You can set the dwell good enough with a .019 feeler gauge & once engine is running warmed up then you can get dwell setup fairly close by just listening.

[@captainjack8823]

Good one Scotty BUT the shop manuals I have say to ALWAYS disconnect the NEGATIVE battery cable BEFORE disconnecting the POSITIVE cable. Note: Both of my vehicles and their shop manuals were made before the year 2000. So things maybe different nowadays with newer cars.

[@sabasc3tube]

It hasn't changed. Negative table off first still applies.

[@imrileth6618]

It doesn't harm any electronics or make any difference in that way. It is recommended to remove negative first so you don't accidentally short circuit you wrench against grounded metal engine or frame parts. So its a good habit when it can be done that way. In some cars like mine the battery is installed in such tight space that you have to remove positive first since negative can only be accessed when fuse box and battery cover is removed and battery is pulled forward from under the windshield where the negative terminal is.

[@kenanderson7801]

Mr. Kilmer thank you your Good will towards vehicle owners is legendary thank you.

[@Spaniard47]

I never would have thought of this! Really great idea. 1 ohm is very little, but it makes sense that it would function as spike protection. Those computer modules have a lot of tiny capacitors, and if all of them are allowed to empty simultaneously with no current limit, it could cause many sections of the module to experience current levels WAY higher than they were designed around, courtesy of the current travelling backwards (no fail-safes). With 1 ohm there's at least a concrete limit that makes all the capacitors empty at a consistently lower rate. Amazing stuff, Scotty.

[@faradaysage15]

Electrician here woth an EE degree and ex mechanic . That's not how electricity works. Backwards? No. Current yravels from ~n voltage to a lesser voltage, any and all paths it can.

Scotty, thanks for all of the great information you share! I've been able to do much more to fix my vehicles now!

[@davebutler3905]

Use a 5W bulb. Yes backwards! The 12V system normally powers the computer, with current flowing into the modules. When the capacitors are discharging, the current is going in the reverse direction. A moden amimeter would show a negative.

Odd thought that might be worth spreading around ... Never mess with the Positive battery cable while the Negative battery cable connected? You only have to short the Positive to some piece of metal ONCE to understand why. 😉
