Trailer Brake Controller Issue

That's good my friend but has nothing to do with the TBC. The TBC has one wire control. My Chevy will not tell me when a 4 pole trailer is connected but will show in the turn signals if a trailer tail light is not functioning. Sure new trucks have better light technology, granted. The TBC looks for a load on the one wire associated with brakes and uses that load sense to determine a trailer connection - ONLY FOR THE TBC. It is designed to NOT be associated with lights and is a safety factor. I can send you pics of how your Pod is wired and connected or you can do it yourself, just find a 7 pin flat standard RV connection diagram, you will see one wire is used from the TBC to the wheel backing plate. It doesn't matter about light technology the vehicle system has to work with the existing RV technology, end of the day the RV brakes have nothing to do with lights and the RV lights have nothing to do with brakes. I can have a disconnected TT plug and energize the brakes with a jumper and not have a single lit light.

Maybe 'm not being clear. The truck is saying "Trailer not Connected" (that may be paraphrasing). That is one issue. It's separate from the trailer brakes not working.

HOWEVER. If the truck thinks that there is no trailer connected, it may be that it has decided that there is nothing there, so has not enabled the trailer brake.

What I am trying to say, and seem to be failing miserably at, is that it may be just that the truck is not sensing the trailer (as in through the lights), and therefore it is not turning on the power to the brakes.

You guys may be right that the Ram senses the trailer via the TBC circuit (I know that our Ford does not do it this way).

So what I'm trying to suggest is that the sensing of the trailer and the operation (or not) of the trailer brakes are potentially two different issues.

BTW - here how tow command works on a Ford: The optional factory in-dash installed Ford Motor Company "TowCommand" integrated TBC (Trailer Brake Controller) system available and compatible on the heavy duty commercial Ford Super Duty line of trucks starting with the 2005 models. TowCommand has since been added to the full-size Ford F-150 pickup and the full-size Ford Expedition SUV. It is built and engineered jointly with Tekonsha who are known for their Prodigy TBC.

With adjustable +/- trailer braking gain in a digital readout from 0.0 (no trailer brakes) to 10.0 (full trailer braking) in 0.5 increments and a manual override lever (to test trailer braking action), the Ford 'built into the dash' TBC provides smooth braking even when pulling up to a 15,000 lb 4-axle conventional (receiver mounted) or 26,000 lb 4-axle 5th Wheel (bed/frame mounted) trailer. TowCommand being different from most aftermarket TBCs, ties into the trucks' computer and hydraulics, so it senses truck brake pressure and can apply trailer brakes as fast as the truck's brakes. Master Brake Systems 'BrakeSmart' TBC is the only other TBC that taps into the trucks hydraulic lines in modern trucks.

The TowCommand TBC is made of three major components; the in-dash TBC module, a TowCommand master cylinder with a brake pressure transducer, and an activated PCM (Powertrain Control Module) parameter by a Ford dealer's NGS or WDS programming method. All 2005 and newer Ford Super Duty trucks are pre-wired for the TBC from the factory, no matter if the TBC option was ordered and installed at the time of the trucks assembly or not.

Before ABS (Anti-lock Braking System) came to trucks in the 1980s, most TBCs were activated by the trucks' brake hydraulic action. In an emergency situation with the trucks ABS activated, Ford's TowCommand can automatically reduce the trailer brake pressure (gain) as it communicates with the truck's computer for faster reaction time with proportional trailer brake control, to prevent the trailer brakes from locking up even though trailers do not have ABS sensors. TowCommand will also inform the driver with an audible alarm and in the digital readout if the trailer wires and/or trailer disconnects from the truck. Next to the TowCommand is an empty storage tray or the $85 optional 4 AUX (auxiliary) toggle switches for winches, snow plow, off-road lights, etc.

The only disadvantage, unlike aftermarket TBCs, is that it cannot be transferred from one truck to another. Another advantage, unlike aftermarket TBCs, any Ford service center can have it serviced. The TowCommand is covered by the standard bumper-to-bumper warranty as long as it is not discovered to be an actual trailer problem. The TowCommand has only been verified to be compatible with trailers having electric-actuated drum brakes (one to four axles) and not hydraulic surge or electric-

From what I can ascertain - major complaint is the Towing App- and visible readout on dash doesn't show a brake failure versus a light failure. The APP provides basic connection info. From above it expalains that alrm sounds if a connection fail happens, but doesn't relate to brake failure. The TBC knows the system has issues but the app relays only electrical info.

Interesting etrailer.com has article about Ford owners adding after market TBC because they want a trailer brake monitoring system, not an electrical system monitor.
