Stan Wright Posted August 8, 2017 Report Share Posted August 8, 2017 Recently I was poking around in my dash and found the wiring and connector for a Traction Control switch tied up to the wiring bundle. Does anyone know if I got a switch and hooked it up would I have a functional Traction Control switch? Would it require dealer programming? I know sometimes options are in place but they aren't ordered or requested so they are hidden away. For instance, my truck came with a single power plug under the cupholders. Behind the dash panel was the connector for a second plug that apparently wasn't optioned...now I have two power plugs. Link to comment Share on other sites More sharing options...
NoDirectionHome Posted August 8, 2017 Report Share Posted August 8, 2017 Do you have ABS? Is it functional? Are you singled? What year truck? Are you really talking about the Inter-Axle lock, and not traction control?

Stan Wright Posted August 8, 2017 Author Report Share Posted August 8, 2017 2004. Tandem. It's not the interaxle lock. It says 'TCS' on the label. Do I have ABS? Good question. I guess I thought it was a standard feature. How would I tell for sure? Link to comment Share on other sites More sharing options...
Scrap Posted August 8, 2017 Report Share Posted August 8, 2017 That is for the defeat switch option. You put in a momentary switch, flick it on, and it'll defeat traction control for 10 min or so. Flick it within those 10 mins and it'll turn it back on. Traction control will have a valve on the control port of the rear relay valve if you have it.

NoDirectionHome Posted August 8, 2017 Report Share Posted August 8, 2017 My TCS switch increases the threshold of slippage when activated so you can spin the tires a little more to get out of certain conditions "There are No Experts, Do the Math!" 2014 Freightliner Cascadia DD16 600hp 1850ft-lb 18spd 3.31 260"wb SpaceCraft S-470 SKP #131740 Link to comment Share on other sites More sharing options...
Scrap Posted August 8, 2017 Report Share Posted August 8, 2017 Oops...on highway trucks...yea that's how it works. The switch to add is a mud/snow switch. Link to comment Share on other sites More sharing options...

Scrap Posted August 18, 2017 Report Share Posted August 18, 2017 LOL only the "connected trucks" can change the weather...... And reading back I was wrong again and made it all more confusing than it needed to be..... Mud/snow switch changes the ABS. TCS switch changes the traction control......just like the harness label says..... But I guess that is the point - installing the switch won't turn it all on, the truck needs to be plumbed and wired for it. Link to comment Share on other sites More sharing options...
PSD_Tweaker Posted August 23, 2017 Report Share Posted August 23, 2017 I have the TCS system, it is true that if you don't have the full system optioned into the platform, just hooking up a switch will do nothing. The system does employ the ABS signals to manipulate the braking forces to the drive wheels, but there is at least one major component that is needed. On my truck it is located on a cross member at the rear of the frame. I use the system quite often, when used with chains in snow it will definitely help to keep you moving.

Stan Wright Posted August 30, 2017 Author Report Share Posted August 30, 2017 It appears the answer to my original question is 'No'. The pins on the Traction Control switch I had didn't match the factory connector wiring so I just applied a ground to the control wire. When the control wire was grounded the TCS light on the dash would illuminate, but only as long as it was grounded. My assumption is if the traction control was actually being disabled the light on the dash would stay on. Link to comment Share on other sites More sharing options...
