Help Needed,,,,

 

hello all , I purchased a set of the Tri-mode steps for my 2015 Sierra Denali and followed Phil’s diagram and made my harness but I cannot get them to work correctly. Thinking I maybe Have done something wrong I made a new harness checked it over and over and I bought a new module and to my surprise it continued  to do the same thing. When I enable them and open a door they slide all the way to the back. Today I had tech connect his computer thinking it might need to get flashed or programmed and after 4 hours he could not get them to work. I’m at the point where if I can’t  get them to work they are coming off. I would really appreciate any ideas. Thanks in advance.

Here is my How To Video on how I was able to retrofit these Articulating (Tri-Mode) Running Boards onto my 2016 Silverado LT.  I'll have a complete parts list here shortly.   Enjoy the video

Thanks to everyone who helped me pull this off.  After watching the videos this really wasn't a hard install.  It just took a little patients.  I ended up finding a set of steps, off an 2018 Denali, o

Are both of the running boards doing this (driver AND passenger)? What if when they are retracted and you press the foot switch on the end of the running board, does it swing out to the rear position? If pressed again, does the running board fully retract? 

 

There is a Hall Sensor (basically a sensor that detects magnetic fields) inside each motor that senses the position of the running board. Not entirely sure what happens if these go bad or if these sensors are actually replaceable. I would think this is a sensor issue since the running boards do extend and retract, they just don't extract to the proper position when you open the door. 

 

As I said the Hall Sensor is inside each motor and needs to be wired up to the control module. Each Hall sensor uses 3 wires, a +5V Reference wire, a ground wire (or Low Reference), and the sensor output wire. These go to the X2 connector on the module (the 12-pin connector) and they occupy pins 1 thru 6 of said connector. 

 

On the motor assemblies themselves, there is an 8-pin connector for each, and the Hall Sensor uses three of the 8 connections (pin 2, 3, and 4). You can see these in the Upfitters Body Builders Electrical manuals for the Sierra 2016 and above. 

 

I would double check these wires are correctly pinned, as if they are not the sensor would not work to tell the control module where the running board position is. 

 

Good luck and keep us informed on what you find.
