Thank you for your purchase from etrailer of the Curt TriFlex Trailer Brake Controller # C24VV.

The L.6 code of the TriFlex controller means that your tow vehicle has low voltage and the tow vehicle's battery system needs to be checked. Since your brakes are locking up it could be that you also have a connector which is corroded or dirty that needs to be replaced or your wiring could have a short which is causing an issue. So you'll want to check your trailer and tow vehicle connectors as well as your wires to see if any are frayed, broken, or otherwise damaged.

I have also added a link below to a troubleshooting help article I recommend checking out.
