That's a great price. I was thinking about getting the Autel MaxiDas DS808 but I think I changed my mind.

Eric, how do you like this scanner? i am in the market for one. Review?

I would like to know how the scanner is holding up and if you like it 🏰🏯♏

[@bjohnson9759]

2010 JKU horn suddenly stopped working one day. Fuses were good...watched your video and made the same repair and it worked immediately. Found lots of corrosion inside the coating. Thanks for the video.

[@SuperGlacierGirl]

Eric, I'll give you a tip. Heat shrink can be stretched too. I use either a pair of needle nose pliers or forceps to stretch the heat shrink to fit over the terminal end. Slip into place, heat it and it will shrink right back to a nice tight fit.

[@klwthe3rd]

I love these fairly common component failures that are really a bad ground. Everyone wants to blame the component first but in reality a lot of times it's the power source or a bad ground. I love that mini launch. Wish I could afford it because that would be perfect for a DIYer since it's so small but gives you bi directional controls. Great video.

[@davidb.fishburn9338]

A little late here, but just found and watched this. I hate the TIPM idea. Permanately mounting relays into a circuit board is a bad idea, especially for those on high use circuits, like the cooling fans. I'm glad that Chrysler abandoned that concept. Eric, you may already know this by now, Chrysler has schematics/illustrations in the wiring diagram section that show where every connector, splice, and ground are located. Very useful for when you're looking for things and don't want to tear the vehicle apart to find them. It's saved me countless times.

[@70kid8]

Eric, I have learned so much watching your videos over the last couple of years. I agree with your statement at the end of your last video: "If you don't like how I do things, don't watch my videos". I wouldn't even respond to the know-it-all commenters: it's not an eylet, it's a "ring terminal", you need to get larger sized heat shrink, you need to use rosin paste or liquid flux, you need to use a ratcheting wrench (which you did when you tightened the ground terminal btw), don't quench your solder...etc. That Jeep will be in the scrap heap long before your repair fails. Your honest, you fix things the right way and you don't fire the parts cannon. Thanks for everything you do.

[@SouthMainAuto]

Bah, it don't get to me. Everyone has an opinion :)

[@brianbaker9715]

I really want to Thank you for The Video. I just purchased a 2011 Jeep Wrangler Sahara Unlimited and My Horn wasn't blowing either. Guess what I had The Same exact problem. The Grounds. I took a Jumper and went to ground and sure enough it worked. At first I said I will just run a wire to ground and I said Nope I'm going to Fix it right. I ended up extending the little wires with Butt splicing and Heat Shrink. I separated and soldered the little wires together and then installed ring terminal and tied to Ground. I really think also they have the wires stretched so tight that when the vehicle moves up All over the place The Wires Break. I'm a retired Electrician at a Nuclear Power Plant it May be a Good Thing looks like I will be fixing a lot of Grounds. Thanks Again Sir

[@tonyscola8751]

This saved me hundreds of dollars on my 2010 jeep wrangler spent $44 on parts found the bad grounds and replaced.. this ground also controls side markers and horn .. and other stuff.. thanks.

[@jeremyanthony9300]

man those Chrysler's really keep you busy. thank you FCA for all cars that keeps Eric o's shop so busy.

[@SouthMainAuto]

Amen!

[@dfb1111]

Great video, I was just chasing that G102 ground for the same problem with a RH turn signal not flashing brightly. Quite a coincidence it was the same day you published this! Well done, articulate, methodical, clear diagnostic approach. You are a true professional.

[@SouthMainAuto]

I saw on the diagram that the lights go there also!

[@dfb1111]

@@SouthMainAuto Great tip on the switch being inoperative while in the bi-directional control. That could be a "Hair-Puller-Outer"!

Eric O at it again! Another great diagnostic video! And this guy was up earlllly! Thanks Eric!

[@defendermender4959]

That tick tocking @3:15 is the sound of the time bomb Jeep on the way to the scrap heap! lol Oh and i have those wire strippers you just need to adjust the thumb wheel on the slide for a better bite.

[@johnmckamy6398]

Just had my first summer cold and whoa , What a nasty cold . I remember your video when you were dealing with a summer cold and now I know how bad you felt . nice simple video and I loved the little tool x431.

Thank you for yet another fine example as to why old cars are better than new cars.

Nice to see such good mechanic with your diagnostic skills! Thanks!

Eric o, does it again...even the simple repairs are entertaining ,eric o is a big kid with a new toy.lol.i want one..lol

[@ALZ2526]

Nice diagnostic tool , all the years in HVAC the right tool for the job. Like to see that in the future.

[@DillonTurner395]

Good find! I had to chase a problem with the horn on my 06 mustang so it would pass inspection. Fuses good, relays good. Horn was good when I gave it power. Tested the horn switch in the steering wheel and checked the clock spring all good connections. Diagram showed where the horn button connected to the bcm. checked there and bingo. couple large connectors. got those popped off and sure enough inside this where it connected to the bcm some of the bcms pins had the crustys and one was no longer existant. sure enough that one was my horn. Odd for being in that sealed connection. Ended up getting another bcm used on ebay and now my horns works. Later on I think I may have found why it got the crustys... Friend was riding with me one day while it was pouring rain. Next thing he starts saying his feet are getting wet lol. Found the drain under the wipe cowl was plugged. Filled the hvac box full of water which was running down on you guessed it, the bcm directly below.

[@frugalprepper]

Could have just hooked that noisy power probe up to the positive wire shoved it under the hood and shipped it with a new sounding horn. Thanks for showing the Diag Gun. I am going to consider it. I have been looking at all the 431 stuff and saving my money for a better scan tool, I think that fits the bill and will save me a few hundred. I was looking at Autel, but Keith convinced me Launch was the way to go.

[@frugalprepper]

Sm Ms - It's apparent that you do not know!

[@throttlebottle5906]

if it's fairly soft rubbery heat-shrink, cut the length you need, put it on a pair of needle nose pliers and "pull them open" rotate the heat shrink and repeat, it will stretch out some and likely fit and should still shrink back down without issues :)

[@MerrixsOutdoors]

Thank you very much for this video. This was exactly my problem. I don’t know that I would have ever found thought to check that particular ground stud.

[@125sm3]

Great job Eric O , cant beat getting the horn 😂

[@philjones8306]

This fixed it for me, took me 30 minutes. Thanks !

[@joe2mercs]

Jeepers! Way to go Chrysler! Over complicated horn operation design out weighed by skimping on the fundamentals of corrosion resistance of the wiring harness.

[@haywardsautomotive6156]

Nice diag. Looks like a nice little scan tool and great price! My buddy from FL calls me all the time to help him diagnose his car and he needs a reasonably priced scan tool with bi-directional control...looks pretty good. The compact scan module attachment every scan tool should have. I've sent my Snap-On down the road before.

[@SouthMainAuto]

Oh yeah I have sent a few of mine for rides!

[@kiddbrother3]

another good video on grounds! thanks, Fiat/ Chrysler for job security for mechanics!

[@jeffryblackmon4846]

Good t-shooting. One thought- using flux helps the solder flow better. We used it extensively in electronic assemblies at my employer before I retired.

[@kevinganley6452]

Just had to do the same exact repair, thank you so much!

[@ronalddmeacham3722]

Good videos Eric have been following you for a while now. you said at the end all you really needed was a test light and a buddy couldn't you have used a test light and the panic button on the key fob most Chrysler products are equipped with?

[@SouthMainAuto]

There ya go! That is thinking outside the box, I totally forgot about the panic button!!

[@dm7097]

You have all the cool toys! Seriously though, they are a real time saver. Just out of most of the little guys price range. Oh well at least we can dream about them! Lol

[@panteraklan681]

[@denniswilkinson1118]

Nice job, another happy customer.

[@bighurk30able]

Good job as always buddy I would have thought the bracket the horn was mounted on would have been the ground but I guess that's old school

[@RJMaker]

Man, Eric you have all the nice tools.

[@wyattoneable]

Autel is giving Snap-On a run for the money. That's a price that approaches the DIY'er and I see prices coming down or the capabilities improve in their line up of other tools as well. Nice explanation of the process too. I like "simple, Keith said I was a master at "simple". That still cracks me up.

[@chekelley6861]

wyattoneable launch?

[@spelunkerd]

Yes, Autel may be my next. I believe Autel hardware have a battery that can't be replaced, which sets a limit of how long it will last. New lithium batteries last a lot longer than previous iterations, but it is a little irritating. Also most of these devices have optional annual updates that greatly increase the price, especially for the DIY market where we hope for longer shelf life. The device shown is the Launch, which is pretty cool but which may be harder to read and use. All of these seem great out of the box but the real test comes in a few years. I haven't found a scanner that I don't love to hate.

[@SouthMainAuto]

spelunkerd I just got an Autel MS 906BT. I think it may be right up your alley if you like to tinker on cars. Seems to be just like my MS908 just half the price and a tad smaller.

[@davemc3650]

wyattoneable so autel top line 3k is wourth getting?

[@snowman25045]

I am having a problem with the horn not working on my 2012 Jeep Liberty. You covered this issue pretty well in this video but most of us don't have all of the fancy equipment. One of the first things I did which you didn't suggest in the video is to hit the lock button on your key fob. I did that on mine and the horn honked telling me immediately that I didn't have a blown fuse, bad relay, or bad ground. I haven't torn into the steering wheel yet to check the button or clock spring but I am guessing it is one of them.

[@aleblanc3547]

Always fun to watch, Eric...one thing though, seeing you flick that razor knife reminded me how much I missed ole Mr. Brake Cleaner. :>) Thanks, Man!!

[@bobweiss8682]

Another great SMA video. Are you planning to do a review on that X431 scanner? Looks like a pretty capable unit for the price, and the cheapest one I have seen with bidirectional controls. Would love to see a video putting it through its paces, showing the datastream, graphing capabilities, etc.

[@Paul1958R]

Eric, Another great video! Im exasperated by the fact that the manufacturers feel it necessary to add $500 worth of body modules, can buses, etc, to monitor a $3 horn circuit and the like. OIt just out of control. That is why I will continue to own 15 years old cars that dont have this stuff. Im old fashioned (and old). Thank you and God bless Paul

[@Jack-ns5mn]

Found that end operating wire stripper that has no grooves just a pull blade and has adjustable tension is much easier to use especially under the dash. I never use that one you are using any more.I have two of them. They are just too cumbersome. Had no trouble pulling strands off and virtually instant with no set up so a great time saver.

[@SmittySmithsonite]

I haven't fixed a horn yet on a modern vehicle. This was a great eye opener for me. Comm lines for a friggin horn! What is the world coming to? Contact, wire, relay, horn - what was wrong with that?!? Was too simple and reliable, I guess. They just have to throw a computer into the mix. It's a wonder you didn't have to reprogram the horn after fixing the ground path ...😖 I better not give them any ideas!!! THANK YOU Eric for your help in the last comments section go around. You were right about the ABS module on that Sierra taking care of the no-comm at the FSCM! She's fixed! I just need to have someone program the stupid module - another GM brainstorm designed to vacuum every last cent out of your wallet. Money light and brake light are off, but ABS light is still on for "configuration error" - guess that means programming. I used Stud 2, meant for the trailer brake power (used a 40A J-case), to run power down to the ABS motor (in place of the ABS 1 circuit, which was open). I spent way too much time digging around the harness trying to find the open to no avail. And of course 2 of those 4mm bolts holding the module on, snapped off inside the ABS unit. Lesson learned there - next time I'll be replacing the ENTIRE assembly! Now I'm off to do multiple carb cleans. Got a pair of 70's Evinrude and Mercury outboard motors, a Yamaha PW80, and a Kawasaki Brute Force ... plus about 18 push mowers, lol. I need a break after troubleshooting that Sierra! 😁

[@SouthMainAuto]

Cool man glad to hear that! Hope they get it programmed for you. They are a quick programming on those. What is a carb!? Haha ;)

[@SmittySmithsonite]

Carb = SIMPLICITY. 😁 Love working on the older stuff - I just go through the motions, and the stuff runs, every time. Wish that were the case with me and modern stuff! Good to know about the programming. Thanks again for all your insight!! I thought I was going to be able to stop by there Saturday, but the deal fell through - someone was going to pay me $3 -LARGE (!!!) to trailer a brand new Chevy 2500 ice cream truck from KY back here to MA. Was a little over my towing capacity, but for that money, I'd just do the speed limit. At first he was going to fly me there, until he saw that would've cost him another grand. Figures - I needed that dough!! One of these days I'll get out there and bring you some liquid gifts. 😊

[@TheCowgirlNiamh]

Fancy! Love a fix without needing parts :)

[@Mr92cadi]

G102 = Gone.. good one Dr. O

[@gerardtrigo380]

In the old days we would have just spliced a new wire to the old ground wire and ran it to a new ground position. I found bad grounds on everything from Datsuns to Mercedes Benzs. In my day Chrysler was not particularly noted for bad grounds, Ford was.

[@SouthMainAuto]

Seems around here the Chrysler products are what haunt us

[@ford_performance_guy320]

Hi Eric another great video as usual.Keep them coming and a big shout out from Australia.

[@cheddarcheesehead2799]

Ah the TIPM, or as Chrysler calls it, "The Money Maker". This is one reason I will never own a Chrysler or any other vehicle that makes it so you have to spend $1000 or more just to fix a simple relay. It's fortunate for the customer this wasn't the case. Good diagnosis and repair.

[@joshwinky6005]

First, love you Eric O! Second, DON'T QUENCH YOUR SOLDER YOU GOOF! Doing that will make the solder crack, which will make it fail. Especially since you aren't using flux. Keep up the great work my friend.

[@joshwinky6005]

[@throttlebottle5906]

just jam an extendable pole/window washer from seat headrest to steering wheel horn button. worst that will happen is, you find the issue and it honks until you stop it. perhaps while cleaning your shorts a bit :))

[@TheFirstStater]

My MGA has a line from the negative terminal through a button on the dash to the horn and to ground. Works flawlessly.

[@c0ldt00l]

Great video! This fixed my horn! And my hyper-flash turn signal! Thanks!!!

[@graymodeler]

Mid 90's Buicks had the horn contacts in the air bag assembly. They close circuit when the foam deteriates and burns out the relays and horn coils. Cost me $1000 to get the horn to blow.

[@Chris-Fennimore]

Good video! The Diagun IV is available from AliExpress for $494.

[@Blazer02LS]

Except that is the non supported china version. If you buy the non-US version you get nothing but the tool, no updates or warranty support.

[@Chris-Fennimore]

Well, you wouldn't go back to the retail seller for Warranty or Software updates. You would go to the Product manufacturer's website. I update my Launch tools from the Launch website. Yes, it works fine. Looking over the Diagun's info sheet, it has 2 years of free updates, from whomever you buy it from.

[@MR-je1jb]

This is what you would call a grey market item. It isn't even listed on Launch USA's website, only on Launch China's website. Everyone selling the Diagun IV online is a Chinese company including Kingbolen and Alibaba.

[@v4vauxhall498]

[@thequickbrownfox7289]

Chrysler needs to add a "Check and clean chassis grounds" to the service schedules for their vehicles.

[@oh8wingman]

I realize that years ago we could honk the horn with a cheap mechanical switch and maybe a relay but you have to look at today's sophisticated vehicles with a philosophical eye. If you didn't have all of that myriad of electronic gear to assist you in honking the horn you wouldn't have a reason to buy all that shiny new testing equipment (toys) and your wife or girlfriend would look at you with that look that says, "Do you really need that? The kids need braces, the house is too small, I need new shoes, and the dog has a vet appointment........" LOL
