2007 Chevy 2500 HD Classic & Brake Controller Issues
After three days of failed attempts at making either of my brake controllers work, I have decided to make my first post.
Tow vehicle: 2007 Chevrolet 2500 HD Classic, 6.0L Gas, 4.10 rear end, 4x4
Trailer: 2007 Jayco Jay Flight 27.5 BHS
Brake Controller: Hayes Genesis
I decided rather than order a brake controller, I’d pick up a Hayes Genesis in person locally. I realize many folks use the Tekonsha’s, but I wanted something I could always source at an O’Reilly, Northern Tool, or other shop and I noticed the Tekonsha’s were hit or miss. I do have a backup Tekonsha Voyager I’ve owned and used for 10+ years. This post focuses on a problem occurring with either the new Hayes Genesis I purchased or my old Tekonsha Voyager.
The Genesis shows an error message “OC” (Open Circuit) when there is no trailer connected to the tow vehicle. This is the basic symptom, also exhibited by a lack of feedback on the Tekonsha Voyager when I try it.
- I used the harness recommended by Hayes (081780-HBC) and verified with them to be correct for my truck. There are two 2007 models and mine is the Classic.
- I verified the Hayes wiring chart to the corresponding plug under my truck’s instrument panel.
- There are two fuses that seem to matter: a 40A fuse that sends 12V to the trailer and a 15A fuse that powers the brake controller. Both visually check out fine and with a meter.
- I can measure power back at the 7-way plug on my bumper. I stopped by two trailer places and they said “looks like your controller and plug are working.” So I hooked up a light tester myself to each lead and have tested brake lights, power to electric brakes… It looks like it should work. When I hit the manual button on my controller, I see power coming through the correct pin on the truck’s rear connector.
- I tried my truck to another friend’s trailer that is known to be working. Same results.
- A friend towed our new fifth wheel to our house. Trailer worked fine with his controller. A neighbor stopped by and tested his controller to our trailer, also fine.
I’m open to any ideas…. What else should I check?
