Also y’all, clean all your grounds good. My 2013 had a Bus A failure which can be low battery voltage or bad ground or In my case the relay in fuse box was bad. This can be a very complex issue with a bad PCM as worst case. This video was by far the best I FINALLY found after 2 months and fixing it myself but I’m ordering that relay right now just to be safe. Good luck!
wow, why couldnt i find this video last year? Ended up breaking bolts because i did not realize that i could slide it out. now i know. thanks.
THANK YOU! Ordered the parts on amazon. Penetrating oil worked great. And it was a very easy fix. Appreciate it greatly. 2008 GMC 2500 DMax.
Hi there, thanks for putting together the video, here’s my situation, exact, same truck, and had the trailer brake warning come on, took it into the shop, as I had another issue that needed, addressing, and as soon as I went to go to a trailer it was clear it was not Repaired. I need to check with my shop once they’re open after the weekend to see if they did the same repairs or different, all I know is when I went to go plug in my trailer I didn’t hear the characteristic dings from the cab, and after the first smile knew right away, that my time and money have been wasted, if I can fix my truck at home after watching your video, I/O, you a beer!
Awesome! Ordered the trailer brake relay switch on Tuesday. I started getting the the service trailer brake system on Monday. I get the travel trailer all hooked up and my trailer brakes would not engage (Had reservations for this weekend and was loaded and noticed the trailer brakes would not work). Well, just received the part 30min ago and installed it and what do you know....The service trailer brake system does not show up anymore on my dash. Well, this video helped because my brakes on my trailer now engage!!!!! Beer 30!
Hell yeah!
Worked like a charm on my 2008 gas 6.0L. Thank you!
Same problem on my truck Help me a lot 👏👏👏👏
Thank you so much u are the only person I found that talked about that 30amp fuse , I thought I checked everything. I was getting pissed 😆. 2014 sierra 2500 hd fixed everything
Nice!
Thanks for the video and the links for the parts. Delivered from Amazon like in a day and a half. I have a 2008 dually so mine is on a bracket off the inside frame rail. Yes on the wd-40 spray or something similar. Very easy fix.
Thx so much brother! I had no idea where to start! But do now! U tha man!
Glad it helped you!
Totally fixed my 2008 LMM Duramax! Thanks only needed the relay fuse was fine
Thank you helped me out a lot buddy. Worked great on my 2007.5 LMM
Thank you for the video, I got lucky and it was just a fuse. I loaned the truck out, they pulled a trailer and blew the fuse.
You're welcome! Glad it was a simple fix.
Mine wound up being the relay in the fuse box which I heard a while back chattering badly when it all got damp. It’s the relay second from firewall and can be changed out with parking light relay to check. It’s also same as starter relay which I bought a 2pk a yr ago.
Great to know if I come across this problem, I would of put dialectic grease on the connection but thanks 👍
I replaced the relay but the light is still on. Is there an extra step after replacing the relay or should the light just go off
Thanks Murph! Shop truck had the same issue, got her all sorted now.
Thanks for watching! Hope you are well.
Thank you so much!! Duramax is back in action
I just fixed my 2011 Silverado 2500 HD Diesel and the part was found above the spare tire
Ron name did you have to drop spare to get to it?
Ron name did you have to reset it cause I also have a 2011 HD and changed that relay and light still on
@@Duendes63 mines still on too. What you find?
What size torque head screws?
Replaced mine on my 2011 3500 Duramax last night. Was above the spare. What about the fuse? There's no "Trailer Brake" fuse in the diagram or manual?
Is there a way I can test this part before replacing? I do have a multimeter.
You can always test any relay or switch with a multimeter, by checking resistance, and by voltage.
Mine is a 2011. But no brake power at the plug. Hopefully the relay is
In the same place as yours. I’ll check it out. Thanks for sharing!
Hey there did it work i have no power in my truck plug i have same truck?thanks
@@buddyyll I don’t think my problem was the truck, rather the trailer. Even after I replaced the relay...couldn’t really get power at the plug using a test light. Rather a pulsing dim light. Used a different truck on the same trailer. Still very weak brakes. Found a broken wire on the trailer brakes.... that helped a bunch. So I’m not really sure my relay module needed replacement. Sorry, I’m not giving you much information. Bottom line for me is that my trailer needs new brakes. I’ve already adjusted them out.
Thank you very much. For the very important help great job
I got 2008 Chevy Silverado HD Gas it might be able to find that relaty in the same location?
Just replaced mine and I still have the service trailer brake light.
Pro tip: spray that dirty/dusty connector down with foaming glass cleaner to loosen and flush out debris to make it easier to disconnect.
Love this tip! You'll probably see it in a future video!
Thanks, I needed that info.
What does the red wires do to go to the two stud bolts on the fuse box
Thanks I didn't know why did the light came on know I know
I just got the “service the trailer brake message “ Aswell as the abs blinking on and off when the trailer message pops up, is this the same issue ?
Would this cause the p0571 fault I have the service trailer brake system. My brake lights are stuck on illuminated with the running lights.
I just got the some problem and did everything as the video but still having the problem “brake system trailer” and the emergency brake on too..
I thought it would be the same for a 2010 Chevy suburban 2500 I cannot find this thing anywhere
Question... my'08 will throw this message only when I'm NOT connected to my trailer. When I plug my trailer in, I have to turn off the ignition and restart. Message goes away and trailer brakes work fine. When I disconnect the trailer, the message comes back. Any ideas? Thx in advance!
No ideas on my end. Wish I could help!
Thanks alot man!👍
Thanks ! 👍🏽
Do you have to put the bolts back in or can you zip tie it?
Will this fix work for my 2011 Chevy duramax 6.6
Don’t replace the 9831 relay switch above the 30 amp fuse, that ain’t it! Thanks for the good info
And if this don't work then what ?
what's the reason it gies bad, i have to change every year
I have a 06 Duramax ripped these wires out with the front driveshaft can anyone tell me where those two ground wires go that's on the frame right behind the driver side front tire thanks
Do you have to get the box programmed
@@brianhnatyshyn2939 nope
this did not correct this issue in my 20090 GMC 3500hd Duramax.
What size torques head screws? Can’t see them on my 2011 duramax 3500wt.
T20 or t25. I can't remember exactly
@@youbreakityoufixit9594 My 2011 ended up being t30.
I believe they were the bigger T-30. Often used in automotive applications.
What part of the country you live in? Dang rusted truck, I lived in Chicago and my 2002 truck has just been replaced with a less rusted truck. My issue remains on my 2012 but think my ABS sensor is affecting me. I added new fuse and new relay.
I live in Northern New York. Not the city. If the warning light is still on after the relay and fuse replacement it could be the trailer brake control module. Hope this helps. Thanks for watching.
@@youbreakityoufixit9594 Thanks, I just bought 2 ABS sensors that I have bad, if that dont fix it I will borrow a module from my buddy.
That's a smart approach! Test it before you buy it.
@@cutweldngrind how did you make out with your problem ... i replaced my relay fuze and no luck .....i have see chatter about brake pressure sensor on the master cyl ?
@@youbreakityoufixit9594 i replaced my relay fuse and no luck .....i have see chatter about brake pressure sensor on the master cyl ? any ideas where is the module is that the box right next to the relay??
Damnit so the problem iant the trailer wiring ?
I replaced the relay and the fuse and the service light still on. 😡😡
Question I did that on my 08 duramax but the service trailer break system stills come on any ideas
Maybe a bad wire connection somewhere
Thanks for video help replace same part but the message not go away any fuse related?
Any luck on yours
My relay replacement did not work still getting message going to try replacing module have already replaced main switch not sure what to try next after module
If you google this issue, they recommend checking your master cylinder to make sure you have enough brake fluid. They also recommend filling to Maximum level before buying any replacement parts.
Ty men
thank u got part out 2008 Silverado 2500
@youbreakityoufixit do you have an after market trailer break system or is it from the factory?
It's a factory trailer brake controller
Could you upload cheap mirror mods for 02 f150s?
Where is the jcase fuse located?
It's in the fuse box under the hood. It's on the right hand side of the engine bay as you look at it.
How did you clear the code?
I just replace mine and a fuse and it didn't take care of the problem
Same here. Any suggestions on next steps?
@@RichBigIron I saw on 2 other videos, check ground wires that attached the the frame near the gas cap and also to clean the inside of the trailer plug (the guy in the video used a pressure washer)
fuse ok so change the modul control still have the trailer service brake advise 😳
Do you find your trouble
Mine is the same thing
Changed mine and did not fix problem
you might want to do something with that frame before it get to bad
Totally agree. It's a constant battle in the North East
@@youbreakityoufixit9594 I got and 07 and it still look bran new 80 k miles on it but I live in North Carolina
@@tincupblast9647 I'm jealous!
@@youbreakityoufixit9594 I bet it suck to see your truck go down hill your no doing nothing but driving it what the life span of a vehicle there
@@tincupblast9647 it really depends on the vehicle. It's hardest on trucks. There are so many large open cavities for salt and water to collect. I've see trucks as new as 3 years old with rust over the rear wheel wells.
Your poor frame 😟 where do you live?
It's really depressing isn't it? I'm in the northeast currently
It didn’t fix mine
I didnt fix mine either. Im lost.
J'aimerais que sa soit en français
I’m having a problem with my electric trailer brakes. They work but just barely they don’t feel strong enough and they barely slow down my trailer when I hit the brakes. My truck Gail is on 10 and I replaced my trailer brakes. Anyone can help?
A few questions so I have a better understanding. How much weight are you hauling? What type of trailer? Does your truck have a factory brake controller?
@@youbreakityoufixit9594 im having this exact isuue? just towing a travel trailer. what do you suggest?
Nice rot
Clean the bolts and put never seize on them. Take some pride in your work.
Caught red-handed!
Hey Alex … Make your own video’s the way you want so you don’t have to criticize someone that actually has taken the time too.
No offense, but I’ve watched three videos now and every single one has a totally different solution for fixing this problem. So it would have been nice if you had mentioned exactly how you determined it was the Relay versus the switch versus the control box. You can’t just start off and say its the Relay without explaining how you came to that conclusion. Also, please don’t title this video easy. A cheap and easy fix means to push the reset button or disconnect the battery. Replacing a relay on the frame rail is not considered “easy”
Dude. Take your truck to a dealer then and be quiet.
No offense, but I’m offended.- Louis P.
taking two bolts off and disconnecting a connector is definitely an easy fix😭take your truck to a mechanic bad boy
@@valkyrie_voodoo So is pushing the reset button! Anything above that is not easy
Dude if this isn't considered easy,then you have no idea what a tough fix is. Meaning you probably don't belong having tools. Even if he doesn't explain why he came to this conclusion it's probably the most common. If you are so talented then why don't you make a video
