Troubleshooting "Short" Error Code On Curt Discovery NEXT Trailer Brake Controller C84VV
Question:
I’m installed Curt discovery next 51126 with quick plug electric wire harness 51455 on my Toyota Tacoma 2022. It is working but when I push manual control button display no trailer connected shows ‘Short’. I don’t understand why is it showing because my Tacoma is pre wired to this type brake controllers. I just want to know is it normal or not. If not how I can fix it . Thank you Serg

Hello Surg. It is definitely odd that you are seeing the "short" error code on the Curt Discovery NEXT Trailer Brake Controller # C84VV, especially since your Tacoma was pre-wired from the factory. Nonetheless, this error code is definitely not normal, and is an indication that something is wrong. The display should show the current gain setting when the manual override is applied.
With no trailer connected, the "short" code means that the red wire is connected to ground side of the stoplight switch or is shorted to ground. I suggest that you thoroughly inspect the brake control wiring. You will be looking for any damaged, pinched or frayed wires. Since your vehicle is so new we would usually suggest taking it to a dealership for service.
