The Suburban 2500 I have is a 2011 model. A front and rear ITBC relay module is located underneath the front and rear passenger seats on the frame rail.
It was a Chevy Silverado 2500 HD from the year 5 that I installed the part. There is no information on the number of years it fits or the model.
I am not sure, I apologize.
In short, yes. Regardless of whether a trailer is powered by gasoline or diesel, the brake system is the same.

The 2012 Silverado 2500HD is a 6 cylinder. After an unintentional trip through a farm field, the 4x4 with 0 gas received a Service Trailer Brake System message. This type of failure was widely reported in the research. To replace the old one, I ordered a new one. When I managed to get to the relay on my truck (had to drop the spare tire) I saw that the hardware had quite rusted. I also noticed that the wires had been severely damaged by corrosion. As well as a computer module, this relay is mounted to a separate bracket. As a result of removing the entire assembly, access could be gained to the mounting bolts, and the heads could be ground off to allow I had to remove two corroded wires and replace them with new 12 gauge wires in order to get the error message to stop recurring.
After I had done that, everything was reassembled and the error never occurred again. It is highly likely that the relay was fine, but this was merely cheap insurance for a part that is widely.
It is no longer necessary to service trailer brake systems. This has been a wonderful experience for me. The stupid service trailer brake system I had been tripping over for months, even though both the lights and brakes of the trailer were still working fine. It kept bugging me every time I restarted It was impossible for me to figure out where the problem lay. It seems like people are talking about taking voltage readings, inspecting this and that, blah, The fix is as simple as changing a relay for $15, and it works like magic. I am unaware of why the relay in question did not work, so I cannot report that it was designed incorrectly. It took only 15 minutes to change my hair. There's no doubt about it, it's so awesome people figure this stuff out and share it. It is likely the dealer would have advised him to replace everything from bumper to bumper for a few thousand dollars and everything would have been fine. I think so. I just wanted to let you all know, this is for a The Silverado is a five-door.
I am a stick to it at all costs kind of guy, but GM's idiocy is just too strong. ". In the Suburban, the relay is located just forward of the spare tire, mounted on the top of the controller in the center of the vehicle. There is no way you can just replace the relay beneath the vehicle since it is mounted from above using two bolts. As part of removing the original relay, you will have to pull the controller and the brackets so those bolts can be accessed. If you don't want to mess with wiring, you can easily unplug the old relay, replace it with a new one, and zip tie it back to the It's a five minute job if you do it this way.
On my 2008 GMC Sierra 2500HD Turbo Diesel (LMM Duramax), I fixed my "Service Trailer Brake System" message in the Driver Information Center (DIC). Also remember to check and replace if necessary the 30 amp fuse under the hood (it should be the one connected to the 12 volt.
It was necessary to remove a metal plate with this and another electrical assembly attached to it, and I did that after dropping the spare tire. After plugging in the charger, mounting it to the plate, replacing the plate and the spare tire, there you are! You no longer have to deal with an annoying A total of about an hour was spent.
In my dash, I was getting a code for "service trailer breaking system. ". Following the replacement of this part, the code was no longer present after starting the truck several times. This was located on the inside of the frame near the left rear tire. Videos I had seen had said it should be above the spare tire. Bolts could be accessed from the wheel well, and the spare tire was not needed to be removed.
Another will be ordered so I have one on hand. The error message has been resolved. It wasn't possible for the dealer to identify himself. The problem and error message were fixed after I advised them to install/replace the part. (As they admit) It seems that the tech team is not highly trained on the towing system installed by OEMs. Most of what they learn is through trial and error. The other will be kept on hand in case I need it in the future. I have either my own or know someone who does. This was on standby for a long time and saved a lot of time.
On my 2010 Silverado LT 1500 2WD, I was receiving a warning about the trailer brake system. Even though I have owned this truck since new, I have never tow a trailer with it. It was a perfect fix to use this part. A precautionary step I took was to also change the J fuse under the hood. video on YouTube that shows you where the fuse is located, as well as the specific part.
