Curt TriFlex Trailer Brake Controller A.E. Error Code Troubleshooting


I have a 2017 GMC sierra king cab 1500 pick up truck. I got the dealership to install my Curt TriFlex Trailer Brake Controller last year. This year I changed all the breaks on my three years old trailer. Now my Curt TriFlex Trailer Brake Controller is reading AE. it says, Accelerometer error, powering brakes using default values? I dont no what that means can you please help me out? Thank you.


Expert Reply:

The operating instructions for the Curt Triflex brake controller # C51140, which are linked for you, indicate on page 19 that if the unit displays the error code A.E. this indicates an internal fault with the controller's accelerometer. This is not a serviceable problem and the unit should be replaced or referred to Curt for warranty service under the terms of the limited lifetime warranty.
