In a panic stop situation, and I mean by that a TRUE panic stop situation, which should be EXTREMELY rare, you should reach down and hit those trailer brakes before you step on the truck brakes.

I know this takes concentration, but it is what every big rig driver knows to do to keep that trailer straight. Those who don't do this often end up jack-knifed or worse.

My 2014 Ram 2500 has the same brake controller as the '15 and I feel it works as it should.

I do NOT have to do that, as with my P3 and TV brake pedal switch...it
does that for me when I just touch the TV brake pedal...the brake light
switch sets before the MC rod is moved

Once the P3 tells the trailer brakes to turn on with the preset boost
level...the accelerometer takes over and will continue to tell the
trailer to brake

Then when my foot moves further down to then touch the TV MC Piston
to then develop MC PSI (this is when these MC PSI sensed, highly integrated
brake controls will 'START' to tell the trailer brakes to turn on)...the
TV will then join in braking...which will then tell the accelerometer
that there is even more deceleration...to then have the P3 send more
if it hasn't topped out at 12VDC


As for 'highly integrated'...EVERYTHING on/in the TV's computer systems
are tied in...and...too many times by software coders (not necessarily
an engineer) who know little to nothing about towing

These are the sub-systems that I can think of that are tied to the
computing system(s) of any of today's TV's...heck vehicles..as a buddy
just bought a Mercedes and had to take classes to learn HOW2 deal
with the +100 computers of her C class

• ABS
• Traction Control
• Torque Control
• Tow-Haul
• Sway Control
• Power Mode
• Shift Points

Can even ask if the AWD/4x4/etc are tied into this...betcha a Costco Dog
that it is...

Tractor trailers have had computer controlled anti lock braking systems for years including most trailers.

But in an extreme situation I will always pull those trailer brakes first. Period. While the new systems have REDUCED the tendency for trailers to jacknife or worse it has definitely NOT eliminated it by any means. Getting on the trailer brakes first is always going to be your SAFEST option.
