Accelerating my brake controller applies the trailer brakes

Has anyone ever seen this before...

I have an Hopkins Insight Flex controller (HM47297). It works as it should when applying the brakes, numbers as high as 45/55, however when I accelerate I see the controller showing an increase on the readout... 5/ 10/ 20/ 25/ and even have seen it get as high as 35. Question is, is the brakes actually being applied even though I'm not applying the brakes? Triple checked wiring: Module pack is pointed with wiring to the front of vehicle: Module pack is perfectly level north/south and east/west: Been speaking with Hopkins and they say they have never seen this before. Vehicle: 2008 Chevy Tahoe LTZ Trailer: 2015 Tango 25RKS

  • Did you install this using the Chevy brake control harness or did you splice into the brake light switch under the dash?
  • I would agree but no, the lights are off and no foot resting... It's a perfect ramp up and back down consistent with the acceleration. You take off the number shoots up and as you level out the number settles back down to zero.
  • That would suggest to me that your brake lights are staying on. Are you resting your foot on the brake pedal when you take off or driving with two feet?
    If so then that's probably it.
