That CF is a fault in the system! Inspect your harness especially at the connector, then check your 3 12 volt powers at the connector behind the trailer brake module and then check the 1 ground! If all is good then the module is at fault! If ou have no power check the fuses there is 5 to 6 fuses in the fuse box under the hood!
