I’ll be adding the factory TBS to mine. Once I have the time. Lol. I’ve got the modules ready to go (to get programming done) along with my cluster. There are 2-3 modules, programming, and wiring

From what I've heard, the factory controller can't be added later. Need to look at aftermarket controllers.

Nope. Not yet. Module still with WAMS. No free time Sent from my iPhone using Tapatalk

Free time? Nope, that’s time you’re essentially paying for! Can’t wait to hear the good news....I mean confirmation that I’ll be spending more money on another upgrade!

Following this as I want to install one in mine but I like the factory look

since I haven't seen a pgamboa video about this subject on YT, I assume it's still a touch further down on the upgrade list..

Yup. WAMS has my cluster and TBCM and CCM. Still trying to get them to communicate.

It seems bizarre to me that GM would make something like this so complicated when an aftermarket box can be added so simply (at the cost of major aesthetic points).

Especially when it seems every vehicle with any of the tow package RPOs appear to have the all the hardware to make it happen.. (save the dash switch).

Yep.  There are 2-3 modules that are specifically for trailer brake.  So those items are omitted...even though some of the dash harnessing is present.

Looks like it can be done now. I'll be trying this out in a month or two.
 

 

This is for a replacement, not adding something that wasn't there before.

Not bizarre, it's INTEGRATED whereas the other ones are not.  One gets features not usually available with an aftermarket controller, especially from 2012 on.

I have a question that I can't seem to find the answer to... My RV that I would be towing does NOT have ABS brakes, but the truck would have (most likely, as I am currently without a truck). 

The question is... would the integrated TBC have any advantage over say an aftermarket TBC if the truck I purchased did not have it installed from the factory?

Yes, check the owner's manual of the truck you're looking at for specifics.  ITBC controls sway and the brakes on the trailer during sway for example.

Stock controller can't be added later which is lame ...I went with the Redarc controller too, for the remote control ...here's my version

Gents, at the risk of being sounding dense.  I want to confirm that i cannot just purchase and plug in the new dash piece and controller head?  I bought a tekonsha and was wiring it up and took my dash apart and lo and behold theres the harness for it!  The presense of the harness does not prove that im good to go?

Welcome to the site.

 

No sir, the brake controller is a factory option, and is set up in the ECU, BCM, and so on, it can not be added after the fact.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Have considered installing a DC to DC charger in your camper to replace your isolator?

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
