I was all excited when I installed my own oem trailer brake controller and had the dealer enable it in the computer. Everything appears to present and working in the dash computer / menus.
Problem is, the trailer brakes didn't work.
Testing the plug at bumper, the brake pin gives constant .9 to 1 volt and this does not change whether brake is fully depressed or untouched.
If I unplug the brake controller the brake pin reads zero volts
I checked the harness and looked good. Checked all fuses with tow in the name and looked good.
Got replacement overnighted with warranty and it does the same.
What now?
