CHEVY SILVERADO SERVICE TRAILER BRAKE & WHEEL SPEED SENSOR FAULT DIAGNOSIS & FIX
Vložit
- čas přidán 4. 05. 2022
- Hey guys! Welcome back to the channel. Today we take a look at a 2013 Chevrolet Silverado 2500HD w/ a 6.0l V8 engine. The customer recently purchased this truck at an auction, but the truck has some problems. Along with the ABS and brake light being on, there is also a message in the cluster for "Service Trailer brake", "Service traction control" and "Service stabilitrak". Using the scan tool we find several codes including Can communication codes, C0050-05 Right rear wheel speed sensor circuit and a P0602 TBCM not programmed. Let's see if we can determine which codes are real and which codes were set by previous mechanics.

As a 40 year automotive electrical diagnostician, I have to say your diagnostic and repair procedures are exactly the way I would have done it. Excellent work!
Even though I'm not a mechanic it is so cool to see how a real professional trouble shooting mechanic does it.Keep up the good work and thanks for being an honest mechanic.We need more like you .
Sad that nice truck wasn't tough enough to withstand some mud in the undercarriage.
Great job Eric 👏
I've got a system that puts a pulse in the wire. Then a sensor you run down the length of the harness. when it stops beeping you found your break. its made by power probe and I bought it thru snap-on. Used it many times and it works awesome.
I AM pretty sure many people was screaming through this video, "that knows". Content. Great Video.
Great find Eric. We have exactly those challenges with mega harnesses in our vehicles where there is a bundle diameter the same size of a child hand. Its getting worse with 48V EV and inverter circuitry so hang in there!
Awesome diag man! I learn so much watching your videos. You lay out the process so clearly and explain the theory behind the problem so that I can learn and follow along. It was reassuring to see a professional decide it's time to just splice in a new wire and end the torture. I'm learning as a hobby how to service cars and I feel like a hack sometimes, a lot of youtube videos make it look so easy which definitely is not the case when I try the same thing. It's really reassuring when you show that things can be less than ideal even for the seasoned pros. Thanks.
Absolute masterclass of automotive diagnostics. I bought a 2012 with abs on. Brand new speed sensor was still throwing a code. I broke out the parts cannon and just changed it to a Bosch and it worked and hasn't came on since. Last guy put on a cheap aftermarket part. I figured it was worth $30 to just throw a new part on and hope. I got lucky
Great work again eric im trying to be half the mechanic/tech you are but your vids help me and im sure many others greatly!!! Thanks
Man, you are a wizard at this stuff. Excellent fix with the bypass wire. Sure was nice of someone to replace everything before you took over. Cheers!
Young man I am always impressed when I watch your videos the knowledge that you have is outstanding
Thank you!
I really enjoy your auction troubleshooting vids. Keep them coming.❤
It's absolutely the best informative video I've ever seen on a variety of topics on my truck. We'll done!!!
Kick-Ass Man!! It's the device and the Wiring Prints between connections... Patience and direct focus!! Tech Masters and their Finest of Skilled Technicians. Keep on Truckin!!
I am the new viewer, I which I would've found your chanel when I was an automobile technician, lasted about 25 years in this stuff anyway you're making me want to come back, thanks..
Wow what a mess underneath, but an awesome job Eric! Beautiful truck too!
Eric!
Get yourself a "wire hound". A wire break locator that injects an RF signal that ends at a short or a break.
I'll be sure to check that out! Thanks!
@@ADVANCEDLEVELAUTO Wow, never knew about those. Seems to work like a stud finder !
Excellent video as always. Does make you wonder if the previous mechanics replaced those parts unnecessarily. Great job.
For sure,owner spent a lot of $ , got nowhere, send it down the road! LOL
1 st. Video I watched ! U my friend are good @ what u do ! I just subscribed! I’ve been doing this shit for 45 yrs. & still doing it ! Repairs like this is why! I really like your side comments of mud in your hair,eyes back of your shirt! That makes you real! Your thought process follows my line of common sense! Thanks for reminding me of the hassles of not just “fixing a problem” it’s stuff we have to deal with in the process !
!
Wow Eric. Yes, I was hoping you would find the abs ref wire fault only because you put forth such a tremendous effort. work arounds are good too. the next tech will have to put 2 and 2 together if a dtc on that wheel sensor ever arises. I can't tell you how much I appreciate your vids. Hello from the colorado rocky mountains! God bless bro!
Eric once again dam good job.looks like that p up has gone threw hell. Well done my friend. Sam
This was a great job. What you were working on was a "water baby", a truck that had been in water and mud at least up to floor level, and if above that, the cabin was cleaned up really well, where you could not see or smell any traces or water, mud or mildew. Great job, great choice in running the the wire. My only question is in making the splice, did you use a low temp solder connector with heat shrink tubing over it or a crimped butt connector with heat shrink tubing for a water-proof connection, or some other method? Inquiring minds out here, hanging on your answer for the best practical, water-resistant splicing method. The re-programming of that trailer brake module was an excellent lesson in how to do something many of us would never see done or have any idea know how to do. Thanks again for sharing your knowledge and diagnostic techniques with your viewers.
I always like your videos and the music you use very motivational!!!
Thks Eric. Another great video as always 👍👍 I think you 100% made the right decision to run your own wire 👍
It’s all in the way you “make things right in a hidden way” New owner happy , now Eric can move on to the next can of worms ! You are what you eat ! LOL
Eric awesome job bro.
The diagnosing is pro.
Keep it up brother.
Nice job! Thanks for posting. Great diagnostic work
Very helpful I have same issues in my 2011 duramax thanks for the video

Great video as usual, Thanks for sharing Bro👍

The more videos or what you may call it a case and each one being totally different. Any way you seem to amaze me and I'm pretty sure other persons out there think the same.
Thanks for the great content!
Good job my friend i wood have done the same thing if it was me keep on keeping on
Video cua ban rat tuyet voi. Rat hay. Cam on.ban.❤.
good video you explain very well ,thanks
Thank you!
I wonder if one of those short/open tracing devices would've helped here. I liked the video as always.
Good job on that fix
Great video and repair
Thanks!
Nice job E-rock…..Pine Hollow Diagnostics or South Main Auto had a very similar issue recently too which might be an interesting watch for you after dealing with this one.
Eric @ South Main is a very good wire finder! Difference is, the swearing, bad attitude is a hoot! He’s real good,,, reminds me of me sooooo much of me ! Old & grumpy, but get r done!!! Gotta love him!
good job as always
Thanks again!
Get yourself a Power Probe Ect3000. Connect the signal output to the cable you want to trace and use the receiver to look for the cable along the harness. When the beeping from the receiver stops, that is a general area where the break in the cable happened.
Wow! I learned a lot
Another great video 👍 👍
Perfect. 👌
Electronic modules on the underside of a 4x4 - smooth move, GM.
Good job my brother
Best master
Good job
Great job
Thanks again!
Great video,thanks.Question regarding the repair.Will there be an issue if the sensor wiring isnt a twisted pair ?
informative ❤️❤️❤️❤️
thanks you are just good
Grasias
Awesome
South Main Auto just had a video on this very subject. 😂
Thanks for this video, I'm currently looking at a 2012 Sierra 2500 and it has service trailer brake system light on dash. Is the same issue you fixed on this video? On average how much would it be to fix?
My 2017 F150 had the same problem adding the electricb steering would not work the problem was fixed. New power wire to wheel sensor and had to replace the abs module.
Did you consider having the shop remove the box? Its not that difficult and would provide full access. Either way, great job.
My truck doing same thing, thanks
You’re awesome, wish you were in my neighborhood and 😊
I.would have done.exactly what you did but that was a pickup you tilt the bed up on the driver side to access the top of the fuel tank for a fuel pump or whatever instead of dropping the fuel tank. It's easy and quick.
Man! It's an amazing video. Just one little thing... while you speaking you going tu fast. I can't even keep with the subtitles in Spanish
That was a great fix on your part. Question, when you use a piercing test lead does the pierced puncture require sealing ?
Yes resealing the wires is a good idea, but in this case we ran our own wire so it didn't really matter. Thanks for watching!
Great job, I can see the frame of that truck want last much longer if he doesn't start getting some of that mud off
Main frame rail stuffed full 😐9:15
Some things are meant to “Do Not Disturb!”
Thank you.. Great video as always.
I have a question here on the vehicle speed sensor. I have a car that I swapped its engine and ecm to a higher model. The donor car had ABS while my car doesn't. Since the swap, i have a check engine for this wheel speed sensor. Is there a way to disable the abs module since i don't have it on the ecm so i don't get the check engine light anymore.
It depends on the manufacture. Some models use the same computer hardware wise and the only thing you have to do is change the software configuration. Others are physically different parts and are not compatible.
This could be the greatest video I’ve ever watched on CZcams. I have been fighting with my dealership for four years about a trailer brake warning issue that will go off every four seconds. It’s absolutely insane. Now I’m gonna take all of this information go to them, punch him in the face and tell him to learn how to be a better mechanic and hopefully he will fix it
Good repair. Ya, I would have run a new wire also. Programming went great. Do you have a subscription for GM programming?
Yes. You have to buy a subscription for each vehicle. Thanks for watching!
You'll be much more effective and efficient if you had a PowerProbe ECT3000 for searching for short-circuits and opens.
The symbol indicating that the ITBC needs to be programmed is clearly visible on the barcode label (7:34). Whoever replaced that module is either unaware or did not have the equipment to do so.
Exactly!
@@ADVANCEDLEVELAUTO Action vehicles are no different than any others! We are not to question,, who & why others did what they did! Deal with what you got & repair it! You/ I don’t get paid for investigating the past! Personally , I don’t care,,, get r done! LOL
Jose is very good on his work
Great job. Why you're not using cable tracer?
I've always had hit or miss luck with those things, but it may have been worth a try. Thanks for watching!
Do I need GM specific (there software) to reprogram the trailer brake control module ?
Unless someone has OCD, that's the best repair available at a rational time/cost.
You shouldn't be apologetic for not torturing yourself to find a broken wire. Run a parallel wire, test it, and call it a fix.
Agreed, I just did the same thing to repair my electronic fuel filler flap. Wasn't going to spend hours ripping the interior apart, cut the old wire, ran a parallel one, job done.
Hello Eric I have question , 2015 Camaro with only code U0101 ( Lost Communication with TCM) , everything perfect except check engine light because this code , driving . shifting , Harness all good any idea ? thanks
Trying to trace an open or broken wire can be easy or become a nightmare. Have you ever considered using a circuit tracer? You can actually find where the break in the wire occurs without physically probing or touching the wire. Just my two cents worth.
Would this be the same for a 2008 Silverado for trailer brake , I have replaced that as well as dash electric brake switch, and remain on, Someone put a aftermarket one in, But that dash message is annoying, Also I watched other videos where they replaced without programming on the 08 chevys , help please....
great diagnosis! I think chevy had to put a better protection for the wires against mud :)
For sure! Imagine trying to get a reading on the “ gas tank pressure sensor” without causing 10 more trouble codes!
Another good component replaced because of lack of testing!
Are you using mitchel or alldata
Eric O. From South Main Auto just fixed the same thing in his last video.
Terrific job done well. Leave your business cards at the vehicle auction site.
That would be like “ pulling your pants down in a whore house!” LOL
I have same truck same color same wheels same trailer brake codes also swamped with more mud
I have same problem with my pickup truck.stability service track
Im having the exact same problem. i too want to just run another wire, but at the abs module, im not sure which wire it is by the module. Any help would be greatly appreciated. 2018 chevrolet silverado
Rear driver side wheel speed sensor
Here in Indiana even a pinhole in the insulation is an invitation for corrosion to eat the wire. I didn't hear you mention it, so how about some liquid plastic to cover the piercings.. except you ran a new wire, so nevermind.
U in good ole Indiana too?
@@randyanderson4360 Yessir, and I saw in some of his other videos that he is familiar with liquid tape.
💯👍☝🙏
What is the name of this harness
As an Auction Driver, 90% of vehicles have problems, 50% have serious problems. Unless you're a Technician/Mechanic, you will probably spend plenty of money in repairs. All Sales "As Is, No Warranty."
Wonder how that wire got messed up? 🤔
Aliens!
The mud and grit likely wore through the insulation causing green oxidation and dissolved the tiny wire via vibrations and movement over time.
Same codes came up on mine 2 days later transmission went out
Looks looks this truck has been in a flood or God knows what, my advice to that owner would be to get rid of it.
It’s at a used car lot now! Clean looking work truck! Will be on front row for sale after Eric gets paid ! I hope, great repair!
Another "pro" fix!
Sir can you please send me the valve lash specs for a 2014 Honda Accord EXL Coupe 3.5l V6 .
I’m sure you can find that on google, man.
@@dumbeezy5480 thank you
third brake light is leaking headliner stained
You are 100 percent correct!
I WANT YOUR HELP MY FRIEND I AM FACING A STRANGE SITUATION I HAVE STFT -18% - -23% AND LTFT + 24% AT IDLE AT WOT NOTHING CHANGE FUEL TRIMS ARE SAME.THE 02 SENSOR 1 DONT WORK AND THE CAR STALL WHEN GO TO STOP AT LOW RPM (1000 RPM) .UNPLUG MAF AND FUEL TRIMS GO TO NORMAL AND STALL PROBLEM STOP BUT CONECT MAF AND DISKONECT 02 SENSOR 1 STALL PROBLEM IT GETS WORSE . HOW CAN I BE RICH IN STFT AND POOR IN LTFT?ΤHE MAF READING NORMAL AT VOLUMETRIC EFFISIENSY AND IDLE AND 2500 RPM HAVE READING IN THE SPECIFICATIONS
ECU TO CLOOSE LOOP READ THE PRICES OF THE O2 SENSOR AND THE MAF TO REGULATE THE FUEL TRIMS?DO YOU
THINK IT IS RIGHT TO CHANGE O2
SENSOR FIRST?SO THE ECU READ THE O2
SENSOR BECAUSE NOW THE ECU DOES NOT SEE ANYTHING FROM THE DEAD 02
SENSOR! WHAT DO YOU THINK IS MAF OR O2 SENSOR FALSE? THANKS MY FRIEND
