CHEVY TAHOE TRAC OFF LIGHT STAYS ON DTC P1571 & P1689 DIAGNOSIS & FIX
Вставка
- Опубліковано 21 жов 2024
- Hello everyone! In today's video we take a look at a 2002 Chevrolet Tahoe w/ a 5.3l V8 engine. The owners complaint originally was that the brake light, ABS light and Traction control light were all illuminated. They had a trouble code C0267 stored in the EBCM and found that the module was faulty. They attempted to repair the module by opening it up and re soldering some of the contacts inside the circuit board. After the initial repair, the truck drove fine for a few days before all of the lights came back on. When they reopened the module to inspect it, they found that it had been completely burned and fried. So, they decided to replace the damaged unit with a used replacement from the salvage or junk yard. Now there are no trouble codes in the ABS module and no ABS warning lights on the instrument cluster, but the TRAC OFF light on the button stays illuminated. With our scan tool we find the trouble codes P1571 and P1689 stored in the PCM or engine control module.

Very excellent video! The takeaway is: Always ask yourself "Is this the correct replacement part?" before installing it. Rock on, Eric!
Well said!
I’ve been watching your channel for several years now always enjoy your content
Thank you
I learned a lot as usual. I appreciate your use of the scope.
Glad it was helpful!
Scanner Danner sent me here, I like your methods diagnosis. Keep up the good work.
Great diagnosis Eric! Thanks for sharing your strategy on how to pin point the concern. Cheers!
Bro, this saved my friend from going everywhere. Checked the connector and module. It looked like someone messed with it, and bam, the connector didn't match the abs module.
Always helpful. Thanks for the good video's quality like adjusting the camera to avoid glare. Algo great explanation like sharing your questions at the end.
Thanks for watching!
This was my problem the whole time. Thank you so much.
I'm jealous when I see how clean vehicles in Texas are underneath. If that truck was here in the northeast you would probably have to replace all of the brake lines too. Rust issues are responsible for cars here being junked more than anything else.
Good job man. Your patience during work is always good
Thank you
Thank You I be having problems with my Trac light over a year put new throttle body drove months came back on hornace wires light came back on Truck been in shop 7 weeks trying to figure out my friend gave me this video showed mechanic and now he saying same thing this video saying We looking for the peace now wish us luck
very informative! im enjoying and learning watching your vids. looking forward to watch the latest vid
You my friend are very thorough. Thanks for sharing.
Great video and commentary man! . I’m having this issue with my 02 Avalanche. Had No idea about this system before watching this video. But now have some ammo going into the problem. I’ll check back after (hopefully) I fix this damn thing.
damn eric !!! ...... i love the full explanation to your vedio ....keep it up . i might turn into a good mecanic spome day .........burned up alterbator and a new battery with a dead short , turns out it was some sort of " rain gaurd " that caused the dead short , on the starter of all places , but would have never found it had it not been foir your past vedios .....thanks for saving me 547 dollars plus shipping for a new wiring harness !! ......AHO = THANK you in apache bro !
ERIC, AWESOME diagnoses and approach thanks fore sharing brother.
Outstanding video, I have a 2001 chevy avalanche qnd I've been having abs/break - traction off issue for over a year changed out two ebcm modules and no luck. Come to find out thanks to this video
I install modules that do not have all pins . Specifically A4 and B4 as per this video. That was my problem. Thank you
Great explanation as usual my friend. Love his videos. Right to the point..
I had the same problem my abs / brake light came on , I replaced ebcm 2 different ones from eBay and the trac light wouldn’t turn off so I found a place to fix my original ebcm and no more lights or trac light on I have a 03 Yukon cost me $125 to fix
I love your videos keep them coming...they are quite educational.
Wow wow, Advanced level Auto you are great, fantastic job, thank you. Habib Auto from Ghana
Man you are the best! I also kept wondering why you didnt have torque pids:) Now it all makes sense! Awesome video!!
Great stuff brother👍 man that can be frustrating to be that close and all it was, was a different style module. So many times it’s the little things. Had to bring the big dog in to figure it out😎
That wouldn't be hard to miss. But it usually turns out to be something simple. I have to give everyone credit. They didn't just keep throwing parts at it hoping to fix it. Test and prove answers the questions.
I don't think I would have thought to check the number of pins.
Of course, hindsight is 20-15!
I always say. "Try to keep it simple stupid"
Teaching you a lesson always make sure replacement parts are identical to oem
YOU KNOW YOUR STUFF BROTHER.
Great, informative video! Thanks!
When working for John Deere I had a plug that looked liked shit. There was a tiny miserable crack that passed through the plastic that caused issues. Took me an exra day to find.
Good diagnose! Hopefully the new unit will be correct........and work!
They found a good used one!
great diagnosis. Wonder if the old abs module with the traction control is the same part number as the old one.. maybe checking the part number could help here
The number was difficult to read. Most of the digits had been faded off.
Made perfect sense to me. Good Job.
Great job. Maybe that's way the connection was damaged. It was the wrong fit?
That damn thing caught on fire internally
Yeah, and it's located next to the fuel filter!
@@ADVANCEDLEVELAUTO oh shit
@@ADVANCEDLEVELAUTO also if I was the tech replacing the module I would've still checked it to make sure it's the same pins and connector
Another great video Eric I have a 2011 Chevy Tahoe i bought it one year ago used and mine had same issue i put a used brake control module one works fine .
Good job Eric .
Excellent diag as usual!!!
Incredible video!
Thanks!
Hi Eric .great diagnosis as always with new info,
could you please make a video in this field i mean TCS system and how it tied up with other units ,or how to diagnostic using PID and what is known good for this sytem.
thank for the awsome knowladge and god bless you bro.
Good job, Dick love your editing skills too.
Thanks for watching!
Eric not dick
i just went through this on a avalanche and found out there is many different modules out there. some with traction control, and active braking control, others without traction control but with active braking, and others without both lol. the RPO codes in the glove box will tell you the options it has and try to go by that. mine was a nw7 with traction control but no active braking.
having the same problem on mine, just looked in glove box and have the same NW7 package as yours. do you know the part number to the module ?
@@gto.eduardo958 no i dont, sorry.
@@Angryblades all good, i’ll have to research a while. thanks for leading me into the right direction helped me from having a headache !
Can you have a part 2 after installation
Cheers Eric. Great video as always bro 👍
I suspect during the soldering process they created a ball of solder on one of the joints which later dislodged and shorted something cascading everything to failure. If it was a short when they repaired it would have likely occurred right away vs days/weeks later.
Can you list the shop info please? I have a truck I would love to bring in to you guys. Thanks.
DAMM BROO THAT TRUCK IS SPOTLES, here in Canada they are already dust
awesome, well-done Mate it was really useful >> if you can to show us if the ABS module sends voltage to the PCM will be nice
I will try and find one that I can test.
Thx for sharing!
All good.
good job finding that one. This is sesame street mechanics, one of these things is not like the other. I compare all parts, they get boxed wrong all the time.
Have you guys reset the module to the ecu
I'm coming to Texas Eric, we gonna make a million dollars 💸 with our powers combined
Excellent job 👏
Now that would be a great spot to use a different connector coding for a different Control Unit, wouldn't it be? That connector shouldn't fit if the unit isn't the correct one!
can you tell me what is better scan tool launch x431 v pro 4.0 or autel ms 906 or 908 ?
which tool you use?
One thing, we as a shop, always tell our guys....VERIFY YOUR PARTS ASAP. This prevents alot of issues from the beginning. If your getting the wrong part...tell us, so we can get on them (parts suppliers) to get us the right part.
Hey eric what scanner was that you used on that abs job .sam
You can find the link in the video description. Launch X431 pro3s+
Good stuff bro 😎. What would you call your “job title” electrical mechanic?
When people ask me what I do for a living, it's difficult to explain. Thanks for watching!
So why did it work for a week?
Next time when you know a customer have replaced a part, check that part first!!!!
This is why swap tronics is something people have to be careful with. Sometimes options in these computers are not the same.
Eres un chingon
Good job
How can one reach you?
I have a vehicle that needs work
Lesson, trying to save some money always is going to end costing more.

Hate these things - bad designed to be putting these electronics under the chassis and / or exposed to the elements. Also, this is what happens when electronics-ignorant people try and fix electronics... I agree, that looks like a shorted solenoid (big current short) - a competent tech would check all the solenoids before randomly touching the solder joints; if it was a stray solder redo, it would most likely just blow the stray solder trace itself.
Anyone else wanna know what the cops found in her belly? lol (ad on the code search page).
I was like why is this ad coming on his screen? What's he been searching for? lol
Lol 😂
Hey I would love for you to work on my truck.
way too easy for this to happen. too many options
I pm’d you
dont use fake thumb nail
Why is it always the first, or the last, thing you think of?
I'm surprised there were no codes for circuit integrity.
