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,

Just for the benefit of others since I couldn't find the exact part number on the forum and one part number I did find here were sensors that didn't work. The correct TPMS Sensors for the refreshed 1500 is gm 31533166.

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.

I am looking to get a set of 2020 chevrolet 20" take-off rims to replace my factory 2006 Yukon Denali 17" wheels.
My question is 2-fold.
Do you guys think these should fit first of all?
...And secondly will my 06 GMC recognize the 2020 Chevrolet tpms sensor if I take it to have them reprogrammed?
