@sicktrickintuner: you didn't by any chance, have Chinese food for dinner, did you?? Lol
I have a 98 Jeep Grand Cherokee 6 cyl. After a mechanic broke a wheel speed sensor, the ABS dash light came on and the brakes acted funny. They replaced the sensor twice and the third time the ABS light came on, they said the ABS Module was bad and they wanted over $1000 to replace it. I bought a rebuilt one from an ebay seller for $80 and it worked perfectly. I watched a few UA-cam videos showing the repairs to the module and since I was a retired electronics technician, I opened the defective module and repaired it in under 30 minutes. Bad solder connections were the only problem. The hardest part was opening the sealed module and then resealing it.
yeah, my 2000 chevy Silverado was close to $1000 15 years ago. ABS light came on while on a trip to Southern California in the desert. Took it to a dealer and wasn't sure if they were taking advantage of an out of stater but after some checking it was what they cost back then.
I had a mechanic break a wheel speed sensor on a 95 grand too. They beat the hell out of a brake rotor and broke the sensor.
I cut mine open, resoldered , resealed the module. Fixed.
I broke my sensor the other day. I bought new one but still not work correctly. So you're saying it's possible to damage module just from breaking a speed sensor?
@@derekmitt23 No - the ABS Module failed after they replaced the wheel speed sensor twice but it was just a coincidence
If I lived near south main Id be there for everything just from watching the videos can tell you take True Pride in your work KEEP IT UP ERIC don’t have a lot of these people around
I think that if those of us who would like to live near South Main Auto actually *did* live nearby, they would have to have bleachers in the front of the shop, and nothing would get done there.
If I lived near SOUTH MAIN AUTO, I would affix a catch sheet under my vehicle, so the rust chunks won't fall on him while he works on it!!
I do live near SMA.
Thanks for sharing and describing the wiring schematic and the CAN signals. Really enjoy when you walk us through the wiring schematics. A very big and important part of the whole troubleshooting process. Thanks for sharing. Artie ❤️
The ability to read a wiring diagram and visualise it against what is in front of you is priceless, not many people "have it".
You've made a very valid statement. Diagrams aren't a topography map, and having to read a schematic and ignore the topographical suggestion of it can be difficult.
@@Resistculturaldecline topography maps are hard enough to read
I totally agree
"If I can do it, you can do it" Yeah Right.
Another great video sir. Great diagnostic process, too many technicians lack the ability to fully and properly diagnose a bad module. Quick, methodical, confident diagnosis, just as it should be.
Mini series!!! Besides, its a Chrysler product so you know theres gonna be a part 2!!
That and the "To Be Continued" at the end...
Wonder what his first clue???
Things that make you go HMMMM!! Lol
Got a thumbs up from me just for the Fluid Film shirt!
Hey Eric, don’t know if you know there’s a company called BBA in Taunton Ma, that repairs ABS modules, instrument clusters, pcm, tcm, etc, cheap dough and super fast turn around. It’s worth checking them out.
did a quick check, they have some rough google reviews (depending on what was sent in for repair)
They have been great for our two shops they will ask you what code you are getting and will determine if they can actually fix it or they will tell you up front if they are not sure until they open it up usually a one day turn around for us but our two shops are in Massachusetts.
Love to see a part 2; hope you get the job. (or find an obvious fault at or around the module itself). Thanks, always enjoy your content.
Great diag Eric - like your simple deduction process.
Perfect Video to teach troubleshooting WK electric gremlins. Once the signals get into the BUS they get lost is space. Eric's testing the connector for power and ground and working bus was exactly the right way to find the problem. Now to find a cheap DIY scope to verify the two Canbus wires.
Thank You for your help and inspiration. If you weren't 500 miles away would be at your shop in the morning!

Another great video! Sunday I represented SMA with my new SMA T-Shirt!
First module that could go bad was in the Seventies with electronic ignition. Now we have lots of modules. As the video first started I'm thinking a module issue (just guessing). But your tip on bigger pins is right on with power and ground. In a perfect world you have known good modules laying around. It takes a couple of years to figure out common module failures like Ford's old TFI modules. Good work as always !
Ford thin-film ignition modules were made in France! Modules were not upgraded so purposely made to fail.
@@GregoryBirulkin no wonder they'd give up so easily lol
Really, transmissions, engines, and rear ends are modules. The "Field Replaceable Unit" (FRU) designation is tighter - you are not supposed to go inside a FRU.
Chuck Norris doesn't need to talk with an ABS module the module spills it's guts out of fear of Chuck Norris. All jokes aside, nice job Eric O.
Chuck's cars don't need no darn anti-lock brake modules!! The brakes are too scared to lock up!!
Chuck Norris's tank don't need brakes cause everyone moves out his way
Peter Martinez
Chuck Norris don’t need no stinkin tank! Enemies turn and run at the sight of his guns.
Inside taking a coffee break from yard work this morning. Discovered notification of two new SMA videos. That's the end of yard work for today. Oh, well.
Ah yes, the Apollo 13 instrument cluster! If only Jim Lovell had had it this easy.
Eric I think if it wasnt for Chevys and Jeeps you would be ...thinner.

I'm diggin that test light with the headlight bulb. I have one rigged up that I use for load testing circuits. I used it in my last video with the Dodge Ram. Thanks for the video!
The scope is such a beautiful tool for these types of diags. I got my MicSig (just a starter for now; it's what I could afford!) about six months ago and in no small thanks to you I'm leaning a lot more of how to use it. Found a blower motor that would intermittently speed up when hitting bumps in a Cheevy with only 34k miles. Without the amp clamp to catch the power spike and the psm signal being measured to prove it was internal to the motor not the control module it would have taken a lot of work to try and find a short or some other issue. With the scope I had proof and it did solve the problem and proved the new one no longer spiked. Not only was it easy but ensures warranty pays and we don't get a charge back! Same with a cam actuator solenoid. Signal is good and solenoid it outside the range. No circuit tests needed. The digital visual proof that comm is there while the malfunction is there eliminates a tedious GM procedure on testing the part and circuits. What i'm trying to say is thanks for being a great teacher and skilled mentor big guy!
Do you know what scope is his go to these days. Looks like he’s using a Bosch here
@@ronaldkleinsasser2842 Not sure. He's got a lot of options. I think it depends on the difficulty of the diag. For a simple speed sensor its easy to pull out the miniature one, but the pico is probably still king.
Very nice Dr. O!! You're getting so good, that Marie don't have to check your work, behind you, anymore!! Lol
I was voting for the TIPM. I blame it for ever thing because.... is an easy target!
A perfect Monday morning on a Tuesday. NEW SMA JAWN!!!!!
??
davecc0000 😂 it’s the day after Labor Day. Feels like a Monday...on Tuesday 😂
Hardly any videos and then a Jeep one....
Seriously Eric have a word with yourself mate 😜
I had to change my ring tone. Every time you phone would ring, I would look at mine. Keep up the expert work.
Thanks for the great video. it helped me diagnosis my caravan with the same Teves ate mk 20 module. Sent module to Module Masters for repair. Abs works great after the repair. Used foxwell nt630 elite for diagnosis.
Cool diagnosis look forward to a part 2 hopefully.
love it cant get enough keep up the good work buddy from the U.K
Very informative to watch!
Your diagnosis work is insane.
A Jeep without a green explosion in the TIPM?!! That's unheard of...
Must have already been repaired.
Gone are the days of Eric alone, working late to get caught up. SMA is full of activity! You keep bringing in techs you're going to need a bigger shop!
The Struggle I’ve seen videos where Eric said that he just wanted a small shop where he did it all because he thought it would be hard to find dedicated employees. I think that fame brought so much business that the small shop with a one man show ship has sailed. Now it’s 3 guys and even Marie seems to be stepping up to the plate and getting her hands dirty.
Nice diag...hope you get the job! Thanks for the video!
A warm hello to you from Sweden! Big fan of your channel! Recently had the abs light come on my 2003 Jeep WJ 4.7 in some snowy weather and I'm just doing some research before I start poking around. Can you simply swap out a broken module with an identical used one without risking bricking anything or setting off some immobilizer or does it have to be programmed to my jeep? I assume disconnecting the battery is standard procedure before doing the swap.
That sounds from the next bay sounds like money maker.
What we have here is a failure to communicate
V8Snail
Cool Hand Luke...err, Eric.
Since you can't talk to the ABS module, I guess that means it has antisocial brakes (rather than antilock brakes)?
😛
Abs module .Well there goes that trip to Disney World.😥
Anytime your Can Bus is putting out that's a good thing.
Okay, well, let's see what she says. Thanks Dr. O!
Just got done watching tv bloopers and then turned you on! Couldn’t stop laughing and had to stop watching!! Lmao!!!
Who`s this new guy on SMA, we want the girl back. LOL. Missed you, Eric.
Notice I see a lot of Jeeps broken on your channel. Why am I not surprised.
What ever happen to your Jeep? Is it done for also?
"like a ROCK, sittin on the side of the road.... like a ROCK..."
Wasn't that Chevrolet's jingle?
G'mornin, Eric! Thanks for the video!
Not going to lie but I thought I was gonna see some sparks flying from the thumbnail 😂
Eric, knowing how much you dislike Dorman products... i found one you might not think so poorly of and even have a chuckle from it. #13422 a Cotter pin assortment.
I'm curious too say, u made the call on the abs mod, question is would you still comdem abs mod if it was showing erratic voltages on the network when plugged in? In the vid You would think the mod its fine since it didn't do that or drop the network. Love the content by the way
Of all the scanners you've used which one is your go to
ABS modules seem to fail alot across alot of brands
bmw
Eric, why did you grab the Bosch scanner this time? Is it because this is a Chrysler product? Or...?
davecc0000 Bosch have wiring diagram. They are very expensive and more advanced then autel.
Wearing my SMA shirt to work today...
Chrysler never lets you down
WOOOOOT!!!........get to see another vid. SWEETNESS
Quick question. Awesome channel, btw. An often overlooked tool you use very often is your service carts. Might I ask where you acquired them at? Looks like the cart my sixth grade teacher wheeled the projector in on.
I believe in an older video he said it was from a school district
@@superjoe83 ok thanks.
Thanks Eric.
nice video, very helpful
Just a thought. Wouldn't it be interesting if when ever you did a segment on a particular brand of vehicle you also wore a hat with that brand name, such as a Chevy hat for a Chevy, Ford for a Ford and so on. All just for play that is.
as usual great job!!
And the first words out every customer's mouth will be How much will that cost. I know I would too. Lol
ABSOLUTELY!!
The first words are never "TAKE MONEY FROM ME"!
GREAT DIAGNOSIS WOULD LOVE TO SEE PART TWO..., IF POSSIBLE THE PROGRAMMING DONE WITH AN AFTERMARKET SCANNER NOW THAT WOULD BE SOMETHING VERY NEW . MAYBE WITH ONE OF THE LAUNCH X431 SCANNERS OR JUST AN AFTERMARKET ONE BECAUSE YOU DO HAVE THE KNOW HOW AND THE EQUIPMENT AND ONE OF THEM SHOULD HAVE THE CAPABILITY . ALWAYS ENJOY LEARNING SOMETHING NEW ON YOUR CHANNEL THANKS YOU FOR YOUR TIME ! ! ! JUST CURIOUS IS ALL WELL WITH KEITH DEFAZIO JUST ASKING BECAUSE HAVEN'T SEEN MUCH FROM HIM LATELY THANKS AGAIN ?
Cool find
Eric, is there a site or option (free or payed) for DIY's to get detailed wiring diagrams when our Haynes/Chilton's manuals don't cut it?
Jorden Epps alldata diy.
www.bbbind.com. Look under resources
Jorden Epps Try BBBind.com They have free wiring diagrams.
notorious for cold solder joints
Mr O,did Marie check your work?lol,nice,quick diagnostic effort from the legend!
Hey Eric. How’s the, uh, soccer scene.
It's got a rainbow of codes including radio
14 years of vibration, I wonder how the circuit board looks. If she buys the repair I suggest opening up the defective one for giggles. Might have nasty's in there or a cracked board or open solder joints.
three words (salt water corrosion)
Hello love ur videos. Quick question, on a chrysler 300 c 2006. Abs module wiring harness, coming out of the module towards the vehicle there is a black cable that is cut. I have looked everywhere for the other side of the cable and wiring diagrams dont show a black cable. I have the abs bas light on. Please help.
so much to know about networks did the abs work ?? just not communicating and with the engine light on no ny inspection sticker even tho it works fine but one sibling wont talk to the others. that abs gotta wedgie? lol
Hi, great work, thank you.
My question is about the wiring diagrams on the BOSCH tool. It that a separate subscription?? Im in Australia and having access to good wiring diagrams is a real problem. Does Bosch provide the wiring diagrams with their tool?
Michael Galvin He is probably accessing Mitchell/AllData/Identifix on the tool, separate service. I would run that stuff on my scanner, but we don’t have WiFi in the shop
Bosch provides the wiring diagrams (I have an OTC Evolve it has Bosch software).
Nice job
One out of three Jeep owners are as unhappy with their purchase as the other two.
Previous owner of a 2000MY, 210'000 mile WJ Grand Cherokee Overland with the 4.0 straight six. Great car, really comfy, built like a tank, but with a pretty poor interior quality, (it was the Wifes car)
Whilst I was working away, she traded it in for a one owner, 90'000 mile 2006 WK Grand Cherokee Overland 3.0CRD with full main dealer service history. What an absolute stinking heap of shit it was.
The paint looked like Stevie Wonder had painted it. All WK's that I've seen in any other colour besides silver have awful paint. It rusted worse than a 1970's British Leyland product.
The 3.0CRD diesel returned worse fuel mileage than her old 4.0 petrol and was dangerously underpowered. The engines are supposed to be 217bhp, but I'd be surprised if they are even 150bhp. The auto box was clunky and slow witted.
The ride quality was the worst of any car I have ever driven, (and I've personally owned over 40 cars in my life). It was like it was over-dampered and under-sprung, with a harsh, crashy but also wallowy ride. Whoever signed off on that ride quality needs taking outside and beating to death.
It was plagued with constant electrical problems. The dashboard thought every day was Christmas with the amounts of lights that would flash on and off seemingly at random, and often different one day to the next.
Jeep under Chrysler were really well built. Jeep under Mercedes were absolute heaps of shit. I should have known how bad it would be having previously owned a Mercedes CLK back in the early 2000's. That was a heap of shit also.
Jeep? That's Chrysler in general.
1999 Jeep Cherokee, with over 280,000 miles!!
I HATE THIS THING!!! It's only two wheel drive, and in excellent condition!! 99.9 percent of the brite red paint is still brite red! Same factory engine! Same factory trans. Same factory interior, only, the headliner is held in place with a couple hundred push pins!!
Damn Jeeps!! Can't make a headliner glue that lasts 20+ years!! Dangit!!!
roadkill5333 : I’ve no complaints about ‘proper’ Jeeps. They used to be built like tanks and ran forever.....
Then Mercedes took over and they became utter shite, (just like most Mercedes really).
Yeah!! Forever!! My neighbor has one of those Jeep Comanches!! 1989 I believe!! He just rebuilt his engine, himself!! Had a machine shop work it, and did everything else!! We don't get the rust down here, in Mid Tenn!! A lot of salt, but only once or twice every 52years!!
Yeah yeah, Jeep Cherokee....I want to see Eric O fold up into a sputtering Tata Nano.
The one good thing about Fiat Chrysler is they allow automotive techs and mechanics to make a good living!
Surely the quality of the product has improved infinitely now Jeep are no longer Mercedes owned ? That probably says more about Mercedes quality than it does about Fiat quality.
Quality is at an all-time low with Fiat. Not one single even-semi-smooth model launch since they took over. None of them have been on-schedule, mostly because of quality issues (their specs are just that lousy)
Gilles Thibault : How on earth could the vehicles have been any worse quality-wise than they were under Mercedes ?
@@frazerguest2864 Guess why FCA still makes the DS Ram? Why has the Grand Caravan just been discontinued, instead of the Spring 2017 as it was supposed to? Quality problems. Every new model launch under Fiat is more of a s..t show than the previous. No wonder their customer satisfaction, and reliability ratings are in the basement!
Gilles Thibault : The thing is, you kind of expect such woeful quality with FIAT, (Fix It Again Tomorrow), it’s the shit quality under Mercedes ownership that pisses me off the most.
In the small town that I live in is a guy driving round in a 1989 Mercedes 190. Besides the faded paint and worn drivers seat, the car is like brand new. Still runs super smooth and has zero rust. I also see a 2007 Mercedes S-Class S500 driving around locally. Besides the bumpers, ever single panel is riddled with rust, as are most Mercedes around here approaching ten years old. That in itself is just one perfect example of Mercedes so-called ‘quality’. I’ll tell you what, I don’t see Fiats and Alfa Romeos rusting as badly as Mercedes.
All manufacturers seem to be following the same path, (with the exception of Toyota). Accountants have taken over from Engineers. Cars are built to the absolute cheapest price. If a car manufacturer can sacrifice quality to save 1 cent per unit, then they will do.
Cars used to be the second highest purchase a family would make, which is why most folk used to own a car for ten years before selling it on, (or scrapping it). Now with the advent of cheap finance / lease deals, cars have become a throwaway consumable item, built to last the duration of the warranty and not a day longer, (and sometimes not even the duration of the warranty, which often isn’t worth the paper it is written on).
But such is the way a lot of our consumer driven society works. Just look at Apple products. Clever marketing aimed at the hard of thinking = sky high prices, yet the products are utter dog shit, often not fit for purpose and you’re lucky if they last two years before becoming nothing more than an expensive paperweight.
I went into an engineering workshop a few weeks back. They had a lathe and a pillar drill in use that the firm had bought in the 1950’s. These pieces of equipment had been used every working day for nearly 70 years and were still going strong. I bet the same wouldn’t be possible if you bought new engineering equipment today. It would be scrap mental after ten years.
Volvo Trucks is another great example. They used to be real tough workhorses. Now gearboxes and turbochargers costing several thousand pounds each are consumable service items.

Can't say I like the scotch connector. Not the greatest choice under a hood or anywhere for that matter.
Thanks for the video.
I learned 30 some years ago that if you use them anywhere they can get wet they will corrode.
Crushing it!
Aren't they known for bad solder joints inside?
Do you have any idea how to depin the ABS connector? I bought a 2010 WK and it appears that someone moved some wires in the connector. Thanks.
What’s the best way to test a TIPM on a 2006 Charger? My high speed cooling fans will not come on. They may cycle for a split second, then not return. If I don’t use the AC, the engine light turns off. If using the AC, the money light will return on the second key cycle. I’ve replaced the radiator & fans with the same result. Checked the wiring and all the relays. I’ve acquired another TIPM from a salvage car, but haven’t swapped them yet. Thanks.. great videos.
The best way I've found is never by a Dodge or Chrysler.
@@blackhatter011 It's a 13 year old Vehicle most of the Ford Taurus and Impala's are already in the crusher WTF? So the guy needed a module big deal....You should go take your mopar hate BS to the Scotty channel !
@@robc8468 Butt hurt Nogopar fan girl.
I have noticed that you switch between a regular test light and your home made test light with the larger brighter bulb i assume the home made light loads the circuit can you help me to understand when testing circuits when to select the home made style or the regular style light?
I'm guessing "Part 1 final" means she decided to drive without ABS, the cost is too high for an old vehicle. On a day to day basis, the only thing one would notice is the annoying dash light.
The CEL is also tripped. Don’t believe it will pass NY inspection with the money light on......
Eric is too legit to quit !
MORE VIDEOS!! MORE MORE I SAY
Hopefully it was just the module, power and differential bus seems happy as larry :-)
Treat it like a starter motor, hit it with a hammer :-D.

Or a mid 70’s Ford electronic ignition module! They would always get you home if you had the foresight to carry a BFH with you.
seems to me somethng that makes .50 holes is better suited ;)
Muy interesante. Amigo espero un día ser igual qomue tu en mecánica
Is there a way to diagnose if CAN signals are working if you don't have a scope like that? Any way to do it with a DVOM or test light ?
Good moning.
How was your Labor Day?
Cheers
What scan tool are you using? The green one.
After multi high priced scan tools were used (many dollars), I found a bad ABS module on my '98 Dodge. My opinion is ABS is useless.
I am confused, if there is no comms problem, wouldn't the can signal be skewed ?
lol, maybe they spliced the front wheel speed sensors together to fool the thing and not replace one or some chinesium alarm/immobilizer/logging or vehicle motion pickup?
nothing surprises me anymore at finding stupendous things
Show me like you did before love you videos
I'm waiting on my coffee cup.
Nice!!
340K subs now Eric...Geez Louise .. my town population is around 9000 lol you have more then 25 of my towns of people watching you..how do you feel about that ?

I have the same problem with a 2007 Camry. I tried a junk yard replacement and didn't work, I plan to mail mine to a repair shop for about $ 200.00. I still drive it by using a GPS phone app that tells me my speed, since the broke ABS module disabled my speedometer.
You're *sure* the VSS is okay?
I vote speed sensor first parts cannon already been thrown keep going
Just curious, if the ABS module is left unplugged the brakes would still work ok ?
No sometimes you will get pulsation when you brake
@@miguelare3
Ok thanks.
many times the can bus runs "through" the abs module and doesnt stop in them as a dead end, so it unplugged could break communications with many modules.
even if it is the canbus termination endpoint, it unplugged means no termination resistors and same non communication or very noisy bus issues of random whack-a-mole com failures
@@throttlebottle5906
Ok, I think if it was just unplugged, it would cause more problems than if left as was. I hate when any warning lights come on though. Its even more aggravating when you take a. Car to a shop they say its fixed but all they did was remove the light bulb that was on instead of fixing the problem
Got a 2008 2500 recently I lost my abs system uo121 and p0501 ... This has shut off my exhaust brake and all and related like speedometer. I don't see any bad wiring at the sensors. One thing I found that started at the same time is the reverse lights stopped working and I noticed they work..key off...when in reverse but there's no power key off . I will need to check my abs module for power and ground and power key on ...but like I said I know reverse is showing no power key on but has key off power . Would there be a possible ignition switch wire issue to look for ?
Is the ABS module made of ABS plastic?
