Question:

I installed my new hubs and electric brakes SA 10 on my utility trailer. I have a Curt Triflex already installed in my 2011 Toyota FJ. I hooked up the trailer and tested the brakes with the manual control all the way to full power and and the highest sensitivity. I could barely feel the trailer brake working. I do not have any strange codes on the controller. Any suggestions?

Expert Reply:

I recommend putting a tester on the 5 o'clock pin of your 7 way connector on your FJ Cruiser. This is the brake controller pin. Hit the manual override and see what your readings are. The Curt TriFlex Trailer Brake Controller - 1 to 4 Axles - Proportional # C24VV is a proportional controller so only the manual override can be tested accurately when still using a multimeter like # PT89ZR.

I've attached a troubleshooting article to assist.
