Any help before I have to leave the truck at the dealer for a few days would be great.
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.

Anyone using the GM trailer TPMS optional sensors?

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
I am currently in the market for a camper and I am wondering how much weight I can tow. I have 2019 Silverado 1500 RST 5.3 V8 crew cab short bed. From what I can find online I should be “okay”, but really wanted some feedback from those of you that have a similar setup. I am aware the 2500 is the ideal setup, but that will be down the line a bit for me.
Truck Trailering Info:
GAWR RR 3800lbs
Max Payload 1819lbs
Max Tongue Weight 960lbs
Curb Weight 5281lbs
The camper I am looking at has a dry weight of 6300lbs and GVWR of 9,480lbs (no intent to load our camper down or travel with full tanks). Hitch weight of the camper is 680lbs. 32’ 11” tongue to bumper. Really only looking at going camping within 100 miles on the weekends.
We typically travel light with basic necessities for hook up campgrounds (clothes, food, chairs).
any help would be great!

I have a 2015 GMC Sierra 1500 Denali 4WD and I would like to install some Timbren bumper stops. On their website there are 3 different kits for the rear:
1. Regular Suspension
2. Magnetic Ride suspension and,
3. Adaptive Suspension
I came across an article stating that the my truck has the Magnetic Ride suspension but I need someone to confirm the fact. Also if anyone else installed these kind of bumpers can you please share the part number that would fit to this specific model of GMC?
