Brake controller not operating trailer brake

2016 Tundra 4x4 factory brake controller will not operate trailer brake. Any fixes out from Toyota?

 

run a search on forum plenty of info...s.b. flash helps but doesn't make it a tekonsha(sp?)

 

Hey thanks. Found a T-SB that might help. Hoping so anyway. Was one of the selling features on the truck. Let’s list the problems. Warped rotors at 15gs, no storage except dog house, exterior sensor replacement, blind spot has to be turned off when towing, harsh ride, etune problems, bad millage, brake controller not functioning. Can’t read gauges in low light, This is my first Tundra 1794. Dealer wants two weeks to look at the problem an says there is no T-SB. Guess if I want to tow the boat I’ll have to borrow my friends 250 Ford

 

the sb should help... If I tow anything other than small dump trailer I hook up my Tekonsha... very easy...one plug

 

I had a TSB performed on mine within a week after purchasing due to towing a car cross county. I'll see if I can find the TSB (might be a newer one available now). I believe the TSB indicated the VIN numbers of the impacted vehicles.

Edit: TSB is attached although this doesn't reflect the 2018's. This TSB was published in June 2017. Posting anyways as it may help someone else out.

 

2016 got flashed last week.
Works like it's supposed to now.
8000#+/-,set at 6.5 slowest it down nice now.
Before flash all or nothing at 9.5 in automatic mode,always worked in manual mode.
Just hated to have to think about putting my hand down there..

 

Hey thank you
Have appt with local dealer. Soonest is two week out. Although they told me they checked for TSB an found nothing. I’ll take the number with me that has been posted. Right now I’ve got nothing to the bumper. Thinking they may turned it off somehow. I had asked if they could turn down the blind spot sensor in the computer somehow. When I picked it up they showed an told me to use the brake gain to adjust the blindspot sensor. I did not say anything to them, figured it was a wast of time. Service manager is always right you know
