GM Integrated Brake Controller

Hi All -

I reviewed some of the prior posts concerning issues with the GM controller. Save me a little research and tell me what you think.

Truck is new (2016 2500 HD). Trailer is 2000 Sunnybrook.

I am getting the trailer connected/check trailer wiring/check brake wiring...

Never had issues with connection beyond the occasional cleaning etc. Got the new truck and have had nothing but problems. Figured it was the old pigtail so I put a new one on. Same issue, but I did notice it does not seem to plug in firmly. Shook the pigtail and noticed I was getting the warnings. So I wrapped it with a velcro strap. Went on a short trip last week. Still got warnings, but mostly only when I hit a bump, and then it would continue to ding, ding, ding, ding. I'm still hearing dings...

I had to pull over once and redo the velcro. It stopped for quite a while..until I hit a bump.

Checked the trailer wires best I could and did not seem to matter if I shook any of the obvious wires under the trailer. So I think it is right at the connector...

Connector on the truck is the problem?

  • I think you answered your own question, it is a connection somewhere, likely near the plug at the back of the truck, but not for sure.

    My 2011 had a problem once, I unplugged and plugged the connector several times and made sure the lock was latched on it (plastic cover that holds the connector in). No problems since.
