Any help before I have to leave the truck at the dealer for a few days would be great. 2017 Silverado Dual 7 pin and 4 pin connector Test the 7 pin : 8 volts when grounded to the wiring harness Test the 4 pin : 7-8 volts when grounded to the wiring hardness Test the 7 pin : 8 volts when grounded to the Frame Test the 4 pin : 7-8 volts when grounded to the Frame 7-8 Volts on when testing at the fuse panel under the hood. Grounded to the engine block. Relay seems good, all 4 fuses are good. Other Fuses like lights, radio and wipers all bring back 12v range. I am not sure where to go from here. I don't want to miss a ground wire or something. I did clean and re-attach the ground wire next to the brake controller under the rear of the truck. Thanks, -
Anyone using the GM trailer TPMS optional sensors?

2020 Rocky Ridge K2 Silverado 5.3L 14K miles First time posting. Have been expereincing intermittent brake lights staying on after engine shut down for several weeks. Took it to the dealership, who ran a diagnostic on the truck and came back with "all things look normal, no codes". By the time I got home, the brake lights were in a state of constant "on" and I was able to restart the truck without applying the brake, even with the key fob outside the vehicle. Received several Onstar warnings to "Service Parking Brake". The parking brake had engaged and would not release. I disconnected the battery for 20 minutes, reconnected the battery which cleared the code. Called the dealership and was told I would have to leave it with them for awhile (several days to a week) to find out what the issue is. Would be ok except they do not provide a loaner car and rentals are thru the roof in our area ($100/day) so I have been living with this inconvenience until I can find an alternative way to work (80 miles rt). Then this happened over the past weekend: While driving back from the lake with my boat in tow, the truck went into a critical brake failure mode. Here is the series of events. Moored boat at dock and went to retrieve truck to remove boat from water. Could not unlock door on truck with FOB. Truck was "dead". No voltage activity. Used 12v portable jump pack to start vehicle. Let run for @20 min before proceeding to drive home with boat attached. Check engine light was on for 30 seconds then went out, but no warning dialog boxes. After we were on the road for @15 min, in rapid succession, I received the following warning dialog boxes: Service Trailer Brake System Service ESC Service Parking Brake Brake System Failure - 62 MPH Top Speed Check engine warning light Traction Control Off warning light ABS Off warning light As soon as I saw this, I tried to apply the brakes and they went to the floor. As you might imagine, it was chaotic in the vehicle when it became apparent that the vehicle along with the 6000lbs of Boat/trailer in tow was not going to stop in any timely fashion. Along with the trailer brake failure and vehicle brake reduction, the backup surge brakes on the trailer would not engage due to the lack of quick inertia braking force. I had the pedal to the ground and eventually we came to a stop. The rest of the ride home (2 miles) was a 5mph white knuckle event. The insult to the injury is there has been no warnings, email, text or posted on account from Onstar about this series of events but... I did get one on the same day that my Oil change is due. I am posting the screen shots I took after we came to a stop. It is being towed to the dealership tomorrow. I will let you know what happens. I absolutely love my truck. It is the 5th Chevy that Ive owned, and sadly the worst one of the bunch. M

Hey everyone, I bought a 2014 Sierra 1500 back in September that was perfect EXCEPT it didn’t come with the oem brake controller. So I contacted my local GM dealer and gave them my vin. They looked up my truck and verified that it was built including the trailering package. This is important because I’ve seen that your trucks computer has to be programmed to accept the oem trailer brake controller, the piece isn’t just plug and play. So I verified this with the dealership. *I’m really thrown off that my truck has everything in the trailer package for that year except for the brake controller* I purchased an OEM piece from another GM dealer on eBay, ACDelco and everything. Plugged it in and haven’t received an alert but I also can’t tell if it’s working. I’m going to try plugging a trailer with brakes in and see if anything changes or if the controller does anything. But from what I’ve seen I should already see a new info page for the brake controller. I’ll update the thread later whether or not it worked, regardless I’ll leave the thread up in case anyone else is in the same boat. If anyone has suggestions or advice it would be much obliged. -
Looking to add the Tire Pressure Sensors to each of the 4 wheels of my RV. If anyone's truck came with these and you do not need them, please PM me

I purchased my 2020, 2500 Duramax in September. I ordered it with the all of the trailering features. I also ordered an auxiliary camera to attach my travel trailer, which I installed in November. It worked great for the first two months. Six weeks ago it stopped working completely. I tried every combination of plugging and unplugging, cleaning connectors, switching between the interior and exterior jack. Finally, I removed it from the trailer and took it to a Chevy dealer. They let me plug it into one of their trucks to see if it was the camera or my truck that was the issue. The camera did not work on their truck either. Chevy sent me a replacement camera under warranty, which I received last week. After installing it, it worked great for two days, then stopped. Has anyone else had similar problems? Thank You

I bought a 2020 GMC sierra that has camera jacks at the 7 pin hitch hookup. I have a travel trailer that i have hooked up a rear camera (used to view on a separate back up screen on top of my dash in old F150). I would like to use this camera instead of forking out $500 for one from GM. I thought I would be able to plug camera feed from trailer (RCA Plug) into trailer camera jack at rear of truck. My first hurdle was the truck jack is not RCA but a PAL(mainly European) connector. Was able to find a RCA to PAL adapter cable. When I hook up trailer and plug in camera, screen says no camera detected. I crawled under truck to make sure wires go to truck camera jack - there is a cable to the rear camera jack but not to the interior camera jack next to it. Does anyone know how to get the camera to be detected?

I have a 2002 gmc sierra 2500hd 8.1 with 7pin trailer plugs in the bed and at the bumper. There is no 12volt power to either plug for top off of trailer batteries or 12 volt trailer accessories...ie winch. I know that gmc has 2 12volt posts at the fuse box and 40 amp fuses to those corresponding posts ( left post controlling the 12v trailer charging and the right post controlling trailer brakes). I have power at both posts, both fuses are good and the trailer brakes work but still no 12v power at either plug. Any one have any suggestions?

Hello, I recently bought a new sierra 1500 year 2020 with the technology package. My boat trailer lights are not constant. I bought a truck side 7 pin trailer tester from Curt. It demonstrates that internmentant issues on the truck side. I took the truck back twice to the GMC dealership and they say they use a gm certified $200 tester and they state the truck is fine. Any thoughts? -
Hey there i am having an issue with my brand new 2020, I installed my new snowmobile deck and connected it through the camper connectors built into the bed using the 4 pin connector and i have tried a 7 pin adapter too. The LED lights on my snowmobile deck turn off and the DIC says trailer disconnected when i press the brake and or use my turn signal. Functionality is restored once i remove my foot from brake or turn my signal off. I need to be towing a real trailer 14000lb and i cant now with my new shiny truck. Frustrating to say the least. I traded in my 2012 and it handled the snowmobile deck just fine with full functionality 2 days ago. PLEASE HELP. -
I noticed when towing a trailer with a trailer mounted crank jack (tongue jack bolted onto the trailer) that the large tailgate on my 2019 Chevrolet Silverado 1500 LTZ Crew Cab strikes the trailer crank jack when opened. It appears the tailgate is much larger than older models so that when the gate opens, it actually hits the trailer mounted crank jack handle and could cause damage to the finish of the tailgate. This seems to be a design flaw with this tailgate. Something everyone should be aware of on the 2019 Silverado. I don't think there is any solution to this issue.

So it seems there is very little info out there yet about how people are using the integrated rear camera. Anyone have experience with it pulling a fifth wheel? I have a 40' 5th wheel and I wonder how good the factory system is, difficulty installing, etc. I think I found that the 2019 camera works for the 2020 ( 84580657 ) but not 100% certain. can't find the 2020 part number reference yet.

No Power At Fuse Box for Trailer Lights
jkrosky posted a topic in 2015-2019 Silverado HD & Sierra HD
I have a 2017 Chevy Silverado 3500 HD High Country with 6.6 diesel equipped with tow package. It has dedicated trailer brake and trailer fuses within the primary fuse box under the hood. My passenger side trailer blinkers and brake lights are not working. I've traced the lack of 12v power all the way up to the 10a fuse dedicated to the right side trailer brake/signal light (fuse #17). I have replaced the fuse, re-tested, and still no power. The left side trailer brake/signal light (fuse #14) has 12v power going to it, tested on the top of the fuse when the flashers are on, but the right side has nothing. I've also swapped and then replaced the trailer parking lights relay switch (relay #63) and still nothing. Is this most likely an issue with fuse box or something else supplying power or ground to the fuse box? Thanks for the help... this is the craziest thing. -
I have a 2015 GMC Sierra and I had a light bar in the back for the brake lights connected to the 4 plug trailer light connector, one morning I started my truck up and the light bar was on working fine five minutes later I go out to my truck and the light bar was off so initially I check the fuses and all seem goodthe blinker lights and brake lights work fine for the trailer but the running lights don't work so I unplug the bar and tested each connector with a tester and found the running lights don't work at the plug. is there anything I can check before I start following wires?

Hey All, New to the forum. Few questions. There is a truck I am interested in and unfortunately I cannot rely on the sales person. Here are the build details from the sticker. What I am curious about is, is this trailering package also known as the "Max Towing Package" ? Reason I ask is the hitch is a GM V-5 which is rated at 12,000/1,200. The owners manual also says the following... 1500 4x4 crew cab short bed 5.3L V8 - 3.42 - MTW 9,100 - GCWR 15,000 5.3L V8 with 8-speed Auto and Enhanced Towing package - 3.42 - MTW 10,700 - GCWR 16,700 5.3L V8 - 3.73 - MTW 10,700 - GCWR 16,700 What I am ultimately trying to do is figure out what this truck will ultimately haul and what its max towing capacity will be. I cannot tell by the build. So I would appreciate any insight/info. The manual says a few things, the door jam says another, and I want to be sure. Build details 2018 - 1500 Crew Cab 4x4 - Z71 - short bed All star package 18" P265/65R18 allterrain, blackwall tires 3.42 rear axle ratio (But not sure if this one has 3.73 due to the trailering package.

2016 Chevy Silverado 4.3L V6 3.23 Reading through the manual: Max Trailer Weight 5,600 lbs, any other weights/limitations I should focus on ? Looking into installing Class 3 Trailer hitch, is a class 3 pretty standard, sufficient ? Im interested in 17-21' fiberglass center console in the future, any issues towing this type of boat (not knowing weight of boat / trailer etc )

Does anyone on here have one of these dump trailers? I’m thinking of getting one for hauling mulch and gravel. I like that it has ramps and I could put my tractor on it. It’s around $3,600 which is about average for this size trailer. http://extremeroadandtrail.com/66108.php

Adapting An Aftermarket Trailer Brake
rallysport096 posted a topic in 2014 - 2019 Silverado & Sierra
So I tried searching in the forum and I'm not sure if it's working right, but I only found one post that addressed this, but the OP I guess gave up on it. I apologize if this post is a repeat. I have a 2015 Sierra 1500 AT and I love everything about it.... except a couple of things I'm working on adding (leveling kit (done), larger tires (done), trailer brake, wireless charger, any mods I can do to the touch screen, etc.). One of those would be a trailer brake control. I would really like to avoid having to use an aftermarket switch, but in doing the research, the wiring harness in the truck won't allow for the addition of the factory module and I don't want to have to try to figure out how to reprogram the ECU to show up on the dash. So, I have to go aftermarket. I purchased the Hopkins Insight controller to try to avoid having the bulky box near my legs but got to thinking how I can adapt the factory switch (which I ordered) to work with the Hopkins controller. First issue, there's a third button for the Hopkins that the OEM module doesn't have, which isn't a big deal, I can figure that one out. Second, and main issue, is the rheostat or slider switch. I will end up doing some testing on it but I wanted to see if anyone has had any experience with this or might know where I can find the specifications or diagrams for both the OEM switch and the Hopkins. My goal is to hide as much of this aftermarket install as I can, minus the display and third button. @pgamboa I thankfully stumbled upon your videos awhile back and was wondering where you obtained your electrical connectors? I want to be able to attach the factory switch as clean as possible and wanted to try to find the right connectors. Thank you! -
I have a 2017 Silverado CC LTZ 4x4. When towing my trailer with 900lbs of tongue weight I sag roughly 3.5 inches. Will Sumosprings help reduce the sag? If so, there is a 1000lbs or 1500lbs capacity. Any recommendations or even better, I would like to read your experience with photos... Experienced the Timbrens and while they manage the sag/squat they are really rough when driving with out a load. Can really feel and hear the impact with 1.5" of clearance. I currently use 1000 lbs Blu Ox WDH and it helps reduce the sag/squat by 1". -
The Service Trailer Brake System light is coming on at random times. The trailer does not have to be attached. It happens when I take my foot off the brake pedal and resets when I restart the engine. I have replaced the module near the spare tire, the controller on the dash and the sensor at the master brake cylinder. I don’t know what else to do.

I am looking for help. I was towing a light trailer over the weekend and used my trailer assist for heavy traffic. On my way to returning the empty trailer an issue arose. First, I was at a stop light when I proceeded to go I hear a small thud followed by about 3 squeaks and it went away. Not thinking much of it because I thought it was the trailer. Upon heading home I was coming to a stop sign at the bottom of a large hill and then a loud THUD come from the rear end. Pulled over and did an inspection but found nothing. I made an appointment with the Chevy dealership for today. Upon taking it there, I heard three loud bangs about 100 feet apart, also from the rear end area. Chevy dealership said they didnt find anything and to not use trailer assist for light loads. As I was leaving the dealership, I came to another stop sign, this time, I took my foot of the brake and the truck stayed in place while on drive, I am also going down a hill when this happened. I gave it gas and there was another loud pop then a "release" of the truck. I have no clue what the hell is going on here. Seems to shift and stop fine. I'm scared to drive this truck anywhere.

John Goreham Staff Writer 8-2-18 The all-new Silverado has so many improvements and updates they are hard to grasp in a single overview. In this spotlight, we will focus on what Chevy has done to make towing easier and more practical for its 2019 Silverado owners. To suit a wide range of owners’ needs, Chevy is offering four distinct levels of trailering capability so owners can buy what they’ll use. The Silverado has three major towing technologies that are added to the already very capable truck. First up is the Hitch Guidance with Hitch View. This adds a dynamic backing guideline to the Rear Vision Camera system to help drivers line up the hitch. It adds precision and a visual cue to make aligning a hitch to a trailer a bit easier. Next up is the Advanced Trailering System. This system itself incorporates three components. First, Auto Parking Brake Assist. This eliminates that annoying bit of movement that you get once you perfectly line up your trailer and then put the truck in Park. It sets automatically when the vehicle is put into Hitch View to help avoid vehicle movement. The third new technology is Chevy’s Trailer Tire Pressure Monitoring System. Before we get too far, you’re going to need some added equipment on your trailer that Chevy can provide. However, if you get it, this feature can monitor the tire pressure and temperature of the trailer tires using the truck’s infotainment system to help prevent blowouts from overheating and low tire pressures. If you like your phone as a tool then you will also like Chevy’s Advanced Trailering System Infotainment app and myChevrolet app. The latter has some simple trailering features such as pre-departure step-by-step towing checklists and a glossary of towing terms. It also allows a solo driver to conduct a trailer light test using an automatic exterior light sequence to help confirm that the trailer is properly connected. The Advanced Trailering System app allows customers to track their miles, fuel economy and transmission temperature of their truck while towing. Brake gain memory is also part of this system and works with the Integrated Trailer Brake Controller, which provides fingertip control of the trailer brakes, to let the customer set and save the controller’s brake gain setting. Last, Trailer Theft Alert can activate the truck’s lights and horn if the harness of the trailer attached to the truck is disconnected. This works with your OnStar Safety & Security Plan and will send you a theft alert via phone, text or email. Chevy’s Trailer Camera Package can use up to four cameras to enable a driver to see a 270-degree view. To take the guess work out of capabilities, Chevy’s new Trailering label is located on the driver’s side door jamb of all 2019 Silverados. The label provides owners with the information they need to calculate before setting out with a trailer. This label takes the guesswork out of towing and hauling and provides information such as: Gross vehicle weight rating Gross combined weight rating Gross axle weight rating (rear) Maximum payload Maximum tongue weight Curb weight The folks at Chevy conducted a survey before designing the new 2019 Silverado. A majority of interested buyers, 60%, said that towing was one of their top priorities in a new truck. We’re one of those interested buyers and our new 2019 Silverado is on order with all of this technology. We look forward to doing a full review once our new GM-Trucks.com Silverado arrives.

Hi all, I haven't posted too many times in the forum... but I have found another question and would like to hear some opinions. I am in the market for a new travel trailer. I have found the newer models are significantly lighter than my current camper. I am currently pulling a 32' travel trailer that weighs in (on the scale) just over 7,000lbs. Being an older trailer, I just don't think it hauls well... (and I will be honest, I have it a little nose down- my mistake when setting up the WDH.) I hate driving this on the highway, I prefer slower state roads that don't face big rigs passing by, winds that blow you around, and generally just feel more in control on them. On the highway, I feel I need to drive slower 55-60 and still keep a hand on the trailer brake. I have also noticed on newer campers they have begun spreading the axels a little farther apart (more stable?). I am trying to figure out if I need to step down in both weight and length to get a better towing experience, or simply lowering the weight (and correct WDH setup) will improve the tow-ability... Will a light but long trailer get blown all over the road? My truck details are copied below from another post; I am well within weight limits for my truck (@7,700lbs). I would like to be able to travel at normal highway speeds- 70-75) and feel comfortable... The hard part is finding a camper with the features we (my wife) wants that will tow comfortably. Suggestions are welcome here too! Bunk Beds, One or Two entry (if one it cannot be next to bunks), sofa, slide out for floor space, queen bed separated by wall... thats not too much to ask is it? (jk- its tough to find without hitting 30'+) If a manufacturer would just make a model with a sofa instead of a slide out dinette we would be sold! *2012 GMC Sierra 1500. Specs on the truck include; 4x4, crew cab, max trailer package (5.3 KDL HD Cooling Package, trailer brake harness, 3.42 ratio). I have installed the Tekonsha P3 brake controller. I currently have the Camco Recurve R6 hitch for sway and WD. The truck manual max trailer weight states 9,500lbs with a GCWR of 15,000lbs (truck GVWR 7,000lbs). I do understand the balancing required between truck and trailer for GCWR; if truck fully loaded is 5,500lbs and tongue weight is 1,000 pounds the max trailer becomes 8,500 pounds not the book stated 9,500. I am thinking a 7,700lbs GVWR for a trailer will fall WELL within specs. I also plan to add SumoSprings to my truck later this spring- and possibly stronger tires on the truck for towing... -
Well, I've done it now... I've just committed to our RV rental for our next vacation. We want to try it out and see if this is something we enjoy or not. I need to add a brake controller to the truck. I'm planning to get the Tekonsha P3, but am open to other recommendations. My question is about the truck, though. Are all the trucks pre-wired to accept a trailer brake controller? Is there an RPO code I can look for? -
Hello, I own an 08 GMC Sierra 2500HD Diesel Crew Cab Long box pick up, it's throwing a display message, but not giving me any codes, the message is service trailer brake system, it used to show that message and then I had it brought into the shop the second of July and they replaced the trailer break relay in the rear, had to change out some eye connectors at the fuse box. They also replaced the fuse. Worked great again from then to about a three weeks ago and this was including an 11 000km trip towing the trailer, it brought the message up again. The truck had been sitting and driven every once and a while, a bit of idling this winter as well, but no towing. so I replaced the fuse because it looked blown. After replaced it work fine again no more message thought maybe wet weather caused it. Now unfortunately now again yesterday I went to use it again and the message comes up, it was just recently used a few days ago and no message, today we have some dense fog as well as some rain. I think it only happens when it rains heavy or fog.. I am not entirely sure on that though. I replaced the fuse in the fuse box for the (ITBC) The one I changed out before to get it to work, and this time it did not work and nothing changed on the dash message still up. I can more than easily replace the Relay without any issues, but I don't want to do that if it is just going to create the exact same issue. Any ideas on what might be causing this? Also on a side note, whenever I start the truck it puts out grey smoke until it has warmed up passed about 79-85 degrees Celcius (174F-187F), which is normally after driving for about 5 mins 10 at most or letting it high idle until that temp, it also does smoke when driving until warmed up. it never puts out black or blue smoke. Its grey, just as it is on a cold day in a gas engine. today we've reached the highest temp lately about 8 degrees Celcius and it still smoked. It never did this in the summer or fall just after it got cold. So I am just wondering if this is normal or if something is causing this to happen when it shouldn't be. Could it be something as simple as it needing an oil change? Or also does it need a long drive at highway speed to deal with burn cleaning the DPF? I am a new owner to this pickup, and it is my first year with it so I am new to diesel's and don't know what to expect from them. Any help Is much appreciated!
