The SC error code on the Valley Journey HD brake controller indicates that there is a short circuit situation. The trailer brake circuit (blue wire on the brake controller) may be shorted to ground.

To determine where the problem is you will need to sever the blue brake output circuit wire and using a circuit tester like a # PT89ZR test for voltage on the circuit from the brake controller using the manual override lever. If the SC code goes away then you know the problem lies somewhere in the wiring between the brake controller and the brake assemblies of your trailer. If the SC code stays then you know the problem is in the controller and should be replaced.

I have included a couple of links to the right on testing and troubleshooting brake controllers for you.

I attached a help article on troubleshooting brake controller installs as well.
