Multiple module faults trailer brake control fault, no pwr at RCM 
Résolu
Ford F-350 2013 6.2 gas engine 74000 km
Multiple module faults. Trailer Brake Control Fault, advancTrac fault, Hill decent Assist fault, 911 assist offline. Airbag light. CD player continuously trying to eject a cd that isn't there.
Found no power to the fuses related to the Restraint Control Module and no power to the fuse related to the Trailer Brake Control. Codes showing no communication to RCM. I clear the codes and the Trailer Brake Control code comes right back and the no communication with RCM comes back. Disconnected battery. Etc.
Starting to think the Smart Junction Box (SBJ) has an issue. Trying to figure out how to confirm this.

My car has almost the same faults; it usually spends more time in the shop than on the road. I haven’t been able to find a definitive solution, and I hope to find a real fix for so many issues it keeps having. Friend, I’d love it if someone could help me.

I removed the SJB (smart junction box)
Or as I always call it. The interior fuse panel. I removed it. Took it apart. And found white corrosion inside on the circuit boards. According to chat gpt this is caused by leftover flux ftom when the soldering was done plus moisture. I cleaned it with qtips and rubbing alcohol. Put it back together. Hooked up the battery and drove it all weekend all over the place. All of the faults went away and i have power at those fuses in thst box. The cd player is still freaking out but that must be a separate issue.

My 2014 has issues like yours as well...thank you for the info! My CD goes into ghost mode as well. I go to blue tooth or radio, the CD will usually stop activating soon after.
