The best mechanic's are the ones that take the time to diagnose without jumping to immediate replacement of parts. Fix it right the first time and word of mouth from customers will keep you in business forever. Thanks for your conscientious quality.
👍
I was a mngr for Firestone for a lot of years. Tech's like this were like finding gold and we did all we could to keep them! Not a parts changer, this guy. Great diagnostic and repair, great video!
Hey Lyndel, thanks for watching and for the kind words! Glad you enjoyed the video.
Mike Becker, Senior Technical Instructor
The BEST RUclips I've ever watched for auto diagnostics and repair. I wish medical doctors were as good as diagnostics as you are Mike.
Thank you very very much!
Mike Becker, Senior Instructor
There are more great techs out there than doctors are. If all the techs were like most doctors, you'd see wheels and parts falling off cars. But yes, there are idiot techs also.
THIS is the kind of Mechanic I want. Someone who is thorough and real good at what they do.
Thank you very much D, appreciate it!
~Mike
You are completely thorough and honest! I loved how you explained and showed each detail. Thank you for letting me learn from this video!
Hey Cheri, thank you very much! Glad this video was able to teach you a thing or two :)
Mike Becker, Senior Technical Instructor
Now, THAT is a proper diagnosis and repair and verification! After what we've been subjected to at high prices and repeat failures, is a dream come true! Thank you, Mike! I have subscribed to success!
I know that this video is some 5 years old now but still. You did a great job diagnosing and repairing this fault. Your last statement about corrosion from aging and environmental exposure let alone the flexing is spot on. One more thing you should do however to address the corrosion at the connector is to apply some dielectric grease to the pins in the connector and to the backside where the wires are crimped to the sockets. Even some water proof shrink tubing will help as well.
Hey Jim, thanks a ton! You're right, a little dielectric in the connector would be a great move.
~Mike
Thank you for this well made diagnostics video. The fact of you not only having know how, but also know why is something to be proud of.
Thank you for watching and commenting Christian! Hope this helped you fix your own car.
Mike Becker, Senior Technical Instructor
I do like the way you work. Being ''CORRECT'' is the best way to be, also honest with the customer. These are the qualities that people look for when looking for mechanics. Keep up the good work.
Hey Richard, thanks for that! Appreciate you watching!
Mike Becker, Senior Instructor
Best honest knowledgeable no bull shit video.
Thank you for staying on point. You are a sharp dude!
Hey CauCajun Man, thanks man! Can you please edit your comment to remove the profanity. We like this channel to be viewable by all. I appreciate the kind words. Thanks! :)
Mike Becker, Senior Technical Services Instructor
Great job! Diagnosing it right the first time leads to fixing it right the first time = happy customers!
Hey Rick,
Thanks for watching!
~Ryan
Great job Mike. A month ago I did basically the exact same as you just did but on an 06 montana minivan. No relevant codes.. Live data to the rescue. Saw the dropouts on drivers front wheel. Set up my cheap little hantek scope right beside my maxidas and could see the bearing respond but the abs module not seeing it. The problem was the exact same yellow wire inside the connector as yours. What a coincidence. As a DIYer it was pretty satisfying to have found and fixed the problem without throwing a bearing at it and still tracking down the problem afterwards. I owe it all to the guys like yourself who are teaching those of us who enjoy learning your craft. All the best Mike.
Hey Mike! Thanks man! Glad you were able to fix it right the first time! Nothing better than proving it before installing parts. Weird it was the yellow wire again...I wonder if it's always the yellow wire...hmmmm...gotta be some fun theory behind why the yellow wire gets it but the blue doesn't...that's a topic for another time :)
Mike Becker, Technical Services Instructor
Fantastic video, by far the best. Helped me use the volt meter, set things up the exact same way very easily. Tested the same way, found a break in the same wire, did the the repair. All fixed, and returned the hub that I was told I needed to change.
Thanks a bunch !!!
Hey Mark, i'm glad the video was able to help you out! Thanks for watching.
Mike Becker, Senior Instructor
I've been following your channel for a year. This is the best series yet. Nice format and clear video!!! Please keep this going.
Thanks Tgoodm1 Glad you liked it!
Mike Becker, Technical Services Instructor
Excellent video! This is the procedure I was going to perform to diagnose my 2014 Impala Limited, but I really liked the harness switch trick you did. Well done! It boggles my mind how many people I've seen on various forums that have gone into a dealership, only to have the hub/sensor replaced, and then driving off and having the same problem recur.
Thanks for watching. Glad you liked it! Little tricks like that can really save time and money!
Mike Becker, Technical Services Instructor
its420erik exactly what I’m going through right now. Just replaced front left hub bearing and rear left . My abs light was on it’s off right now but my brake flutters and feel /sense a spring like noise / vibration. I took my car back only to have it returned with the same issue. This issue has cost me $424.13 so far taking it back tomorrow feeling pretty frustrated! Any advice?
First time on your channel. I have to commend you for a superb video. Filming was great. The lighting and camera work really showed what was going on. Mike's knowledge and his ability to fully explain/describe the issue and fix were very good. Can't wait to look over some of your other videos. I hope to see some diagnostic tools at different price points. I'm a DIYer , so I can't afford top of the line equipment. Obviously I going to Subscribe. Keep up this type of work.
Absolutely FANTASTIC and in depth video. I knew I had an issue with one of the speed sensors, and have replaced both cables on GM's before based on other videos. Replaced them right to the ABS module. I extend the new harness to the module with some old outdoor extension cord. take the remainder of the sketchy GM harness right out of the equation all together. However, I am ashamed to say, that as a former mechanic, I would have never thought to jump from one side to the other to verify, absolutely, the problem. I've done that a lot with other components, speakers, lights, etc. But never thought to do it with the wheel speed sensors. Genius sir!
I'm adding you to my list of Tube videos, you really make it clear as to the problem and the diagnostics. As karma would have it I have this problem in a 2005 Cavalier which is also intermittent. Its going into dealership Wednesday. Used to fix my own, but to old anymore. Thank-you again.
Excellent accurate diagnostic's I like the way you look for the source of the problem before you start throwing new part's at it , and your way of thinking how you can't afford to be wrong because you have to be right, there is no money to be made if you can't fix it the first time in the shop, I love the hands on instruction with the different tools you used thank you!!!!!!!!!!!!!!
Hey man, thanks! I'm glad you liked the video and the approach. Let me know if you enjoy some of our other vids!
Mike Becker, Senior Technical Instructor
One of the best videos all around, well explained, great camara work, clear voice, good professional setup, just great, thank you .
Hey thanks Mxfern12! I'm glad you enjoyed the video :)
Mike Becker, Senior Technical Instructor
You work and think like I have in 60 years of my tech /mech carrier good job great work !
Good job! Great video. I will be checking my olds van and hope to end my abs woes. Thanks for the intuitive video.
Awesome, that's great to hear Keith!
Mike Becker, Senior Instructor
Hi Wells, I am so glad i watched your video. It has explained how to diagnosis and fix the problem with my wiring harness.
Hey C Peake, thanks for watching! Glad the video helped :)
Mike Becker, Senior Instructor
Nice presentation. The camera(s) work and details are outstanding, really good quality. Makes it a pleasure to watch. ;-)
Note to self, must get a car lift... ;-) Already did similar on several cars. Gosh! The lack of a lift makes it a nightmare job. Tedious and time consuming.
Keep up the good work.
Cheers
Hey, thanks a ton! A lift does make this a much easier job!!!
Mike Becker, Senior Technical Instructor
Nice diagnosis and repair Mike. Great to see that Wells makes a quality replacement part for this fix. Thanks!
Hey John, Thanks for watching!
Mike Becker. Technical Services Instructor
Great find Mike and nice repair! The crusty wire closeup shots were cool.
Thanks Glen! It is cool to see what a wire looks like after all that time...I didn't expect that much rust/solidification.
Mike Becker, Technical Services Instructor
Excellent video...only I wish my mechanic was as honest as you are, he and most others will charge you for everything including a wrong diagnosis.
Rick, a good trustworthy tech can be hard to find. I wish you luck in your search!
Mike Becker, Senior Technical Instructor
Great helpful video and good tech explanation,much better understanding of how the sensor does its job,also that there are variations between manufacturer👍
Hey Edward, thanks for watching!
Mike Becker, Senior Instructor
I don't know Mike I'd be questioning my coworker. She took it to another shop first then brought it to you? Haha good job man.
I know, right??? If only they would come to me first! Silly co-workers. She's learned a valuable lesson on this one! Thanks!
Mike Becker, Technical Services Instructor
South Main Auto Repair yeah Hana knew better than to cheat on u, ha
South Main Auto Repair now now dr. O He's still learning my brother. We just got to tell her ( thats your problem lady). Eric your the best and all of us learn from each other.
Thanks for the troubleshooting step. I wish i saw this video before I replaced both front wheelhub assembly on my grand am. I'm still having intermittent abs sensor problem going off.
Hi Mike. I just did this repair yesterday. I just substituted a resistor across the terminals and left the key on with the windows open. I flexed the wiring until the wonderful abs chimes sounded and found the intermittent break of the wiring at the last clip on the control arm before the connector. Great job as always.
Great Detailed video wish all how to repairs were this great!
Thanks David!
Mike Becker, Senior Technical Instructor
If you make a RUclips video Now!!that's how you do it absolutely brilliant Mike.Excellent video !! Thanks for additional pointers through out video.
Sweeet, thanks for the kind words! Glad you loved it!
Mike Becker, Senior Instructor
I'm having a similar issue. I have a 2000 Alero and in the past two weeks the problem started. Prior to this, just after getting my car, it was raining and suddenly my service vehicle soon, ABS, and trac off lights came on. I thought little of it. Then it this winter it would disable ABS and traction control in snowstorms (I live in Minnesota). Thanks for the thorough diagnosis testing. I'll be freerzing my buns off (as long as it isn't snowing) tomorrow on the cold concrete slab that I park my car on (even though it's April 7th tomorrow) checking this.
Hey Tanner, thanks for watching. Did you find a similar problem to this video? Is that what it ended up being?
Mike Becker, Senior Technical Services Instructor
Absolutely wonder teaching video !!! Certainly saves a lot of time and money! Mine was the exact same problem only on the right wheel. Thank you so much!!
Excellent Presentation and logical checks. In my car, I opened wheel hub, sensors. Still have intermittent on off ABS. Planning to check all wiring including ground points . Thanks Buddy 😀
Nice video. Informative, great camera work, and excellent step by step instruction.
Appreciated as always Mike. A nice refresher more than anything though I do love the running the leads across to the other side. Thanks again.
Hey Matt! A refresher is always nice right? Not the hardest of diagnostics...but it is some good testing to be accurate. Nothing worse than guessing!
Mike Becker, Technical Services Instructor
Great video. Note as a electrician make sure key is off and don't cut both wires at the same time. I learned a lot. Thank you
excellent diagnostic and repairs...great teaching hope this is my issue that i can resolve quickly
Thanks for watching! I appreciate it :)
Mike Becker, Senior Instructor
Great video (posted years ago, but still relevant)! One big factor that the viewer should consider before he attempts this repair is whether he has a full sized lift for the car! It would have been a nightmare to try this fix lying on your back under the car on a floor creeper! In some cases with a different harness configuration you could do the job horizontally by jacking the car and pulling off each wheel, but even that way your clever diagnostic trick of cross wiring adjacent sensors would still be hard to do!
In any case, nice work and great attitude about doing a quality, accurate job -- applies even if its just a DIY project not for hire!
Like the old saying "Do it right at the first time" to avoid back job. Good explanation, Diagnosis & Testing., Well done Mate...
Thanks for the kind words and checking out the video!
~Ryan
Great video!!! Thanks so much!!! I will be doing this this weekend. I appreciate the help. Needed a starting point to diagnose and you've given it to me. Thx again!!
Hey Brad, thanks for watching! Good luck on your diag.
Mike Becker, Senior Technical Instructor
Excellent trouble shooting with verification of what you think you know. That's the way to direct your efforts to fixing the problem right the first time. Great video training on fixing this particular problem and in the discipline of troubleshooting and verification. That wire sure cooperated with your video training session, couldn't have asked for a better training aide!
An excellent video! Good easy diagnostics. The only problem is affordability of your scan tool.
Hey Jay, thanks for watching! Yes, the diag tools can be expensive, for sure.
Mike Becker, Senior Instructor
really impressed by thoroughness and well-presented. i subscribed today.
Awesome Ken, thanks!
Mike Becker, Senior Technical Instructor
You do a great job ... I really appreciate you sharing what you know with us.
Thank you for watching and commenting. If you have any more questions, don't hesitate to reach out!
Mike Becker, Technical Services Instructor
Mike I just described your job gave me an example of the problem I have with my Impala the same wire fraying and rust well since I saw your expertise its time to do mine and thank you for such good detailed work!
Hey Tracy, thanks for watching! Glad you found the video helpful :)
Mike Becker, Senior Instructor
Because of these videos I would look for Wells replacement parts.
That's what I like to hear!
Mike Becker, Technical Services Instructor
so much detail! love it!! this channel needs more subs
excellent video. A week ago I got a C1233 (open/short right front). hubs are Timken and relatively new. It is winter. yesterday was below 0°C so there was no water. No ABS light. The day before it was above 0°C and there was water. Light was on. Connected scanner and drove. Wheel speed was being reported by all sensors and were accurate. With scanner I could clear code and it came back almost immediately. Repeated this process a few times. No way to "prove it". Would you recommend replacing wire harness for peace of mind. Bonus: no soldering required since there is a connector at both ends. Best price for harness is $105US + shipping. Car is '97 regal. I take good care of car even though this is a winter only car.
Hey Anthony, I wouldn't ever suggest just replacing something without proving it. There's almost always a way to prove it out. Jan 3rd we're doing a live broadcast talking about ABS signals and fixing issues. You should join for that and then make your decision.
Mike Becker, Senior Technical Instructor
looking forward to the video. I hope I have the necessary "tools" to diagnose.
I think I figured it out. I pulled the wheel off today and the abs sensor wire from the hub clips onto a mount/extension on the backing plate. Thanks to excessive road salt, the mount broke off of the backing plate and the sensor wires were moving around instead of staying in place. The white insulator that covers the wires has been compromised so I suspect the wires inside have been compromised. Will be ordering new sensor wire and soldering it onto the old wire. Hoping for some warmer weather since I will be doing it on my driveway.
This is a great video and very good work, thanks.
Thank you very much!!!
Mike Becker, Senior Technical Instructor
Wonderful Job Mike, your Training Paid off, great video. Two thumbs up.
Thank you so much for watching! Glad you loved the vid!
Mike Becker, Senior Technical Instructor
Great job Mike. Nice video, very informative. Also a very neat and tidy shop you keep. Having trouble with my abs system also. I just bought the truck and had to resolder some spots on the circuit board for my display for my gear shift. While I was in there I noticed someone had put electric tape over my ABS, and Brake light. Dirty trick. Shady to say the least. Thanks for the info. Wish me luck.
Hey Mark, thank you for watching. Our shop is more studio than shop :) That is a shady situation. Hope it's a quick easy repair for ya!
Mike Becker, Senior Technical Instructor
Thank you Mike, I like the the fotos at the end very much. A picture is worth a thousand words. ... Your working conditions are pretty close to optimal. You know that, don't you?
Hey Juergen! Thanks for watching! I thought you might like those pictures. I know, I do have it pretty great here, you'll never hear me complain! It's nice having that microscope, I like to show things like that because many techs don't have the equipment or the time to look that far into it. Thanks again Juergen!
Mike Becker. Technical Services Instructor
Been having intermittent abs & traction control problem on my 2010 Chevy avalanche...
Read the code...left wss changed the hub thinking it was the sensor but upon inspection found out the connector was repaired now I have to do the same as you and trace the wire back to see if it’s any tears further up
Sounds like fun :)
Mike Becker, Senior Technical Instructor
Great job Mike I need to make me some long jumper leads like that. Good little tug test will usually always find the fault lol. But you are absolutely correct in making sure 100 percent your correct unfortunately people do get paid for being wrong they just keep tossing parts then I get them lol. Great job going all the way with diagnosis.
Hey Techman 48917, why make them when Carlos at AESWave can hook you up with a great set? :) It is unfortunate, and all that does is give techs and shops a bad name. A few ruin it for the many! Thanks for watching!
Mike Becker, Technical Services Instructor
best how to video i have seen in a long time. i felt like i was watching a tv show. i guess i was haha thank you so much!
Thank you so much!!!
Mike Becker, Senior Technical Instructor
Should be more mechanics like you Mike, great video
Hey Donald, thanks!
Mike Becker, Technical Services Instructor
I Agree!! Mike I Haven't!!! seen anything like this in all my 68yrs. Wow! now I would be (happy) to pay You!
Hey Billy, thanks! I'd be happy to work on your car if you were in the FDL area in WI!
Mike Becker, Technical Services Instructor
Nice presentation! Detailed, scientific, very helpful. Thanks!
Thanks Walt. Glad you enjoyed the presentation! Thanks for watching.
Mike Becker, Technical Services Instructor
Excellent information and repair! A common problem with GM front drive cars with some miles on them!
Hey Mr. Lucky, thanks for watching! It is a common issue. I hope this sheds some light on the testing and verification!
Mike Becker, Senior Technical Instructor
Great video! I got one for you, I have never had an issue with my ABS or the ABS & Brake lights until the mechanic changed the speed sensors on both front wheels ! Now the ABS & Brake lights will not go off, IF we reset them & turn them off the ABS starts stuttering each time I need to hit the brakes hard . However IF we turn the lights back ON the brakes work perfect.. Have you ever heard of this ?
One other thing, why not just put a new harness in instead of soldering ? Cost ??
Hey John, thanks for watching! When the ABS light is on ABS brakes on not functioning. When you shut the light off they are working. The stuttering you are feeling is the ABS brakes engaging. You could have a sensor signal dropping out due to an air gap issue? Look for one of my recent videos on GM ABS. I describe this exact failure. The reason why this didn't get a whole harness is because there is no junction point. The wire runs allll the way back to the ABS module. Some vehicles have a jumper harness that you can replace. That is the best fix.
Mike Becker, Senior Technical Instructor
@@GoTechTraining Thanks, do you have a link for that Video? I am having a hard time finding it..
I just got back from another Certified Tech who had the correct scanner. not just a code reader . he was checking many fuses saying they are all communicating with what they are supposed to communicate with except the ABS Mod. He recommends me getting a refurbished mod & he will put it in, My problem now is how do I know for sure if it truly is the mod & not what your saying "You could have a sensor signal dropping out due to an air gap issue?" Appreciate your replies Thanks, I wish you all were in my area. You seem to really know what to do here !
John, here's the link. ruclips.net/video/mXSHEtI7eik/видео.html
Watch the video, I think it will help your understanding. Not sure about that module...
ruclips.net/video/mXSHEtI7eik/видео.html
I hear you Mike .
keep up the good work bro ,you're a very good Tech!!
You have an extremely talented Knack of troubleshooting- very impressive!!
Thanks MrRichBiker! :)
Mike Becker, Senior Technical Services Instructor
Great video and diagnosis! The only thing that I didn't like is the very last picture of the corroded wire. That is not normal at all, even for an older vehicle. It's a sure way to have more problems in the future. The corrosion is there and it's going to continue to corrode. One look at that would tell me to replace the entire cable. Speaking from an electronics tech with 40 years experience, and I also help a friend who runs a garage when he has electrical problems. Back to the good, you were very very thorough and many mechanics would have spliced the first broken connection and test drive to find they still have a problem. You got it right the first time and I commend you for that.
This was immensely helpful to me, especially the use of the alternate side harness to identify what was really wrong with my ABS sensor system on that side. After replacing the harness, I examined the old one and found a broken wire, though the insulation was undamaged.
Hey Neil thanks man! Glad the video helped you with figuring this out.
Mike Becker, Senior Technical Instructor
First time on your channel. Highly impressed!
Very intuitive on what's going on .I'm so pleased I hit that subscribe button.looking forward to more vids, thanks for sharing
Hey Johnny, thanks for watching! Welcome to the channel.
Mike Becker, Senior Instructor
Thank you for this. I like your methodology. But I have to ask, why did you chose to use shrink crimps instead of soldier and shrink on weather exposed wiring?
But great video none the less. I look forward to seeing more of your work.
Hey WesterStarThunder, thanks for watching! I have never seen an issue with properly installed heat shrink connectors. I have a long term test going with them now...we'll see how that turns out.
Mike Becker, Senior Technical Instructor
That car is nice for living in Minnesota. Fairly clean frame. :) Excellent job, i've been there, done that. Right before you found the corrosion in the connector, i saw an intermittent speed signal when you were spinning the wheels. Corrosion can cause intermittent problems, and i'd bet that there is a little corrosion in the right side connector, as you said that there was a code set for the right side. It's not enough right now to really be causing an issue that you can actually see. But, you will see the right side setting the code more often as time passes.
Hey David, good ole' northern winters huh? Does Minnesota use as much salt on the roads as we do here in Wi? Thanks! Yeh the signal did pop back for just a second. You are probably right, the right side will eventually fail down the road. It really is inevitable. Thanks for watching!
Mike Becker. Technical Services Instructor
Tried to answer earlier today on my phone, but for some reason my comment was not getting published. I'd say yep, our northern winters can be brutal. I'm in Michigan, and they salt the roads heavily, at least here in metro Detroit.
Very professional, I wish you were in my city, heres a problem I can't seem to get a solution too. 2009 Chevy Express 1500, 2wd, with Stabilitrac. Upon acceleration from a stop it feels like resistance from the rear end, as if someone gently hits the vehicle from behind sometimes, not always. Sometimes the stabilitrac light flashes when this happens. The button on the dash no longer disengages stabilitrac. I noticed this starting 3 years ago when I would get stuck in snow, prior to that never got stuck in even the deepest snow, any ideas, thankyou.
Hey Gerald, thanks for watching! Wish I could help in your city. If the system is faulting there should be trouble codes. Any idea what codes are stored?
Mike Becker, Senior Instructor
I just recently purchased some heat shrink and solder but connectors that I think will work great in areas like this. I hope they will work better then crimped ones.
Thank you for sharing the troubleshooting skills!
Thank you for watching me share my troubleshooting skills Ron :)
Mike Becker, Senior Technical Instructor
Thk-u for the quick response, love watching your videos, have learned alot.
Thanks Jamie! Glad I can help you grow your automotive knowledge!
Mike Becker, Technical Services Instructor
Thanks man , your a good teacher and you kinda look like Jim Cary : ) keep up the good videos !!!
Hey man, thanks for watching! I love Jim Carey, I've heard that before. Thanks for watching!
Mike Becker, Senior Technical Instructor
Your welcome, its the eyes, eyebrows and nose, now if you would just make some off the cuff jokes once in awhile that would be really funny : ) , i used to do 3d faces for Disney some years back ... The thing about your videos is your totally professional and so right about the wrong diagnosis doesn't make the mechanic money just more headaches you got that right !!! It just wastes everybodies time and torques off the customer and next thing you know hes down eating breakfast with his fishing buddies bad mouthing the dumb mechanic and the mechanic loses all sorts of local business.
Haha I'll work on my stand-up routine! That is so true. People will tell everyone if they have a bad experience. Hard to stay in business that way, especially in a small town!
Mike Becker, Senior Technical Instructor
The best youtube i ever seen well done .
Woahhhh thanks Hakan!
Mike Becker, Senior Instructor
wonderful, amazing, have no word for such a wonderful diagnostic and repair.
Hey Ghulam, thank you so much! I have no words for such a wonderful comment :)

Give that man a $100 bill! Good job!
Hey Allen! Thanks!
Mike Becker, Technical Services Instructor
Right? Why can't all mechanics be that careful and thorough? That shop is also immaculate which indicates that this is a higher-end repair facility. I'm still struggling with an ABS error issue from last year with my 2005 Chevy Impala. A local mechanic tried to fix it and it failed right away as I pulled off his lot. He tried again by replacing the hub sensor noting that the new part was defective. It lasted less than a week. All of the info that I'm getting now seems to indicate that the wiring/harness goes bad and GM supposedly acknowledged this. As we can see, ABS systems aren't so simple to diagnose but it can be done, but you need to be very systematic without shooting from the hip and guessing (and wasting time and money). Thanks, Mike.
One of the best videos spot on
3 thumbs up that gives me a clear idea. Thank you.
Thanks for watching Harry!

I have a 2004 GMC Canyon and I’m having some real issues with my Right Front ABS. What happened before I got the error is that my brakes are going out and I decided to replace ALL drums and discs with the help of my dad. We decided to start on the front right disc which does need to have a new disc out. Before we don’t know anything of how my vehicle work or where to unplug the ABS to take the whole thing out. So we went in blind, took the bolts off the wheel bearings but didn’t unplug the ABS. And as he does that the wire gives a resistance and couldn’t let go which messed with the sensor. The left side didn’t need a new disc by the way so that side is good. We run the computer diagnostics and it’s pointing to the Front Right ABS. I ordered a new ABS sensor (by itself) and we decided to take off the old sensor and replace it with the new. We got some sprays that was going to use to clean the wheel bearing to fit the sensor on very well. We unplug the battery for no false ABS readings, started on the whole replacement process, sprayed good on the bearings and put the sensor on once dried. After putting it all back together on my truck, with a new installed caliper, the ABS warning light went off which was a relief. Until, we took the truck on a test run for both caliper and ABS. When I press on the brakes my truck steering shudders to the left and veered my vehicle to the left which I knew something’s wrong. After a couple of brakes, the ABS light went on and the I P Brake lights went on. Now I ordered a full wheel bearing assembly with the sensor and it’s on its way over.
My guess to what happened is that when we sprayed the old bearing to be put to use it messed with the sensor with the moisture or so. Could that be the problem to why my vehicle is acting that way?
It's really hard for me to say what happened without seeing it and driving it. It could be related to the ABS system, it could also be a base brake system issue. Normally brakes get replaced in pairs.

Brilliant! Even your shop is brilliant, even your cars are unbelievably clean, ha ha. The only point I take issue with is your remark that one never gets paid when one is wrong. That only applies in an ideal world, not the world I live in, ha ha.
Hey Spelunkerd, thanks man! It's really kind of a studio/shop. We take a ton of pride in keeping it clean for what we use it for. You are right, there are a lot of poor customers out there having to pay for someone being wrong :(
Mike Becker, Technical Services Instructor
LOVE THE VIDEO AND THE SHOP!! SHOP IS SO CLEAN LOVE IT!
Damn professional. Ladies... this is a pro. He'll be more expensive. But worth it.
lol thanks!

BEST VIDEO SEEN ON ABS DIAGNOSIS AND REPAIR
Hey Daniel, thanks!!!
Mike Becker, Senior Technical Instructor
Great video. Im having the same prob. Abs -Stabilitrak -lights on. When looking for a good repair shop with someone capable like yourself what should I look for? It would be great if you were located near Dayton Ohio.
Hi Gayle,
Looking for someone you trust to work on your car is hard. I would start by looking for someone that is ASE certified. Then I would check reviews left by customers, sometimes they are your best incite to what kind of work the shop does.
I hope this helps! Thanks for reaching out!
~Ryan
Great video, can I get a detailed description of what those fittings/connectors are on the jumper probes? Are they 18 AWG mini female connectors?
Hey Drewnashty, thanks for watching! Check out the UTest Advanced from AESWave, it'll have the proper pins in there. www.aeswave.com/uTest-Advanced-Terminal-Test-Kit-p9748.html
Mike Becker, Senior Instructor
very logic and simple troubleshooting best of luck hope to see more video. thanks keep rocking bro..
Are there any "cheaper" scanners to measure live data from the ABS module? Don't want to spend $1,000 right now. Your video has been a huge help. Very educational and thorough.
very well presented ....when are you coming over to fix mine?
